Learning about electromagnets with Project Attraction from EEME

One of the best additions to our homeschool time this year has been the projects from EEME. Zachary has absolutely loved the hands-on learning and put it well into practice. One could say he is ‘wired’ this way (and yes, the pun was definitely intended)!

Learning about electronics one project at a time and gaining the knowledge of the ‘why’ behind how things work has been encouraging and confidence-building for Zachary. He has since started asking his dad to help out with projects (or may have attempted some on his own – cough), but it has given him a much deeper interest in how and why things work the way they do. 

Learning How to Make an Electromagnet

IMG_7239

Using Project Attraction from EEME, Zachary learned how magnetism is related to electricity and built an electromagnet. The project taught about: 

  • reed switches
  • electric current and heat

Overall, Zachary was able to finish the project in about an hour and a half (build time is approximately 1.5-2.5 hours) because he had a little bit of a hang up on one portion of the process and needed my help. Typically, he is able to work through the steps without parental help (I love that), but the fine wire used in the building of the electromagnet was more challenging and  required a little assistance from me at that point in the project. 

As with all of their projects, there are short step-by-step video tutorials to follow along in the building process. All of the materials needed for the project were enclosed in the box and detailed in the first video:

  • a small magnet
  • an LED
  • a 2″ wire
  • a resistor
  • a reed switch
  • a metal bolt with tape around thread
  • a thin wire coil
  • sandpaper
  • AA battery
  • rubberband
  • paperclip

The timing of this project from EEME couldn’t have been better. As part of one of our co-op classes for The Mad Scientists Club book, the kids participated in a science fair where they chose a short story read during the year and then worked on a project based on what they learned. They needed to explain the scientific principle behind the project and create a display to showcase their learning. 

The electromagnet project fit in perfectly with the story “The Voice in the Chimney,” and Zachary was able to base his entire science display on this project. (We won’t talk about the short detour he took after putting together the project when he considered creating a much larger electromagnet using his father’s riding lawn mower battery. Fortunately, someone caught onto the boy’s mind meandering and he lived to see another day.)

Science Fair Project electromagnet-3-2

On a much more sane note, Zachary put together a science board explaining how electromagnets worked and showed the one he had created using Project Attraction and then another he tried on his own following the same principles learned in the video clips from EEME. I love that he was able to use the one project as a jumping off point to create more and learn more!

One of the big things learned during this process was the heat generated when creating the electromagnet (the bigger one he created generated more heat, so THANK GOODNESS he didn’t get far on the one with the lawnmower battery). The current flowing through creates the warmth/heat and the battery can also quickly drain if left connected. 

Things to LOVE About EEME

Aside from the fact that all the supplies are included in each of the EEME project kits, the video curriculum is well put together and explain the building process in detail. Each of the videos is between 2 – 10 minutes long. In addition:

  • videos explain the step-by-step process AND the principles involved (how/why something works) – a huge help for parents who don’t know the answers themselves (cough)
  • shorter videos help those with limited attention spans
  • comprehension questions ensure kids are understanding what you are doing
  • videos can be stopped/paused if needed during the process
  • the videos are free to watch – check them out here and get a peek!

The projects would be wonderful extensions to current curriculum or even as after school learning – or even make a great gift! There are different purchase options available, including a basic monthly subscription, individual projects, and a 6 month Project Set. They have different purchase options, and we’ve completed the first four projects so far from the basic subscription.  You can find more information on the EEME website, or follow them on Facebook, Pinterest, Instagram, and Twitter.

Egg Drop Experiment – #STEM Challenge for Kids

Apr252016
April 25, 2016 by 3 Comments

 Egg drop experiment #stem challenge for kids

For our final co-op class, the kids were all challenged to create a device that would keep a raw egg safe from a second story window drop. They have had a blast with their prior STEM challenges this semester, and this egg drop experiment was no different. Seeing the various creative ideas each came up with to protect their eggs – and the groans and cheers that resulted was equally as fun as the egg drop itself! 

The eggs were supplied when the kids arrived, but during the week prior there were a few guidelines to follow in creating a protective barrier for the eggs: the completed device could be no longer/taller/wider than 12 inches and they needed to use items they found around the house. This meant that if a parachute was added, it was also part of the 12 inch guideline, so it needed to fit within that parameter. And yes, I brought a ruler. A few kids had guessed beforehand and ended up making last minute modifications to have it fit. 

Egg Drop Experiment Ideas

Ideas from the kids varied and it was much fun to see if they worked and hear their theories as to why they thought it would. Some had tested their devices before coming (and had success), but many waited to see how it would work. 

Egg Drop #STEM Challenge for kids-2

Our first egg drop used an old plastic jar lined with cotton balls galore. The jar was surrounded by skewers and adequately taped. The intent was to drop it and have the skewers cushion the drop so the jar wouldn’t hit the ground. 

Egg Drop #STEM Challenge for kids-40

While the container flipped during it’s drop, the impact wasn’t enough to break the egg and the cotton balls did their job cushioning the blow. The only thing that did break the egg was trying to get it out of the jar. A success! 

Egg Drop #STEM Challenge for kids-4

A recycled dishwasher tablet container filled with popcorn was the second entry. The overall container was very lightweight. 

Egg Drop #STEM Challenge for kids-44

Another egg survival! 

Egg Drop #STEM Challenge for kids-16

A ziploc bag filled with marshmallows and the egg surrounded by a gallon sized ziploc bag with more marshmallows was another entry. Predictions were looking good for this submission. 

Egg Drop #STEM Challenge for kids-28

Unfortunately, the density of the marshmallows was enough to crush the egg and it made a fairly runny mess. 

Egg Drop #STEM Challenge for kids-9

The smallest entry in the egg drop was a little box cushioned with cotton batting, a single egg carton styrofoam piece, all topped with rubber bands, the lid, and secured shut with a few rubber bands. 

Egg Drop #STEM Challenge for kids-34

Even though it was so small, it worked beautifully! 

Egg Drop #STEM Challenge for kids-5

A single roll of toilet paper with the cardboard tube removed and wrapped in duct tape was a cozy home for another egg. 

Egg Drop #STEM Challenge for kids-48

The squishably soft goodness of whatever brand used was enough to cushion the drop – another survivor! 

Egg Drop #STEM Challenge for kids-15

Bubble wrap around a small box was a last minute pull-together from one of the boys who may have forgotten to work on his assignment until the last minute. A parachute was also part of the plan, but was nixed due to size limitations. 

Egg Drop #STEM Challenge for kids-20

Fortunately his last minute effort paid off and his entry made it! 

Egg Drop #STEM Challenge for kids-13

This next one was fairly simple: tissue paper surrounding an egg with extra cushioning inside a plastic baggie then placed in a paper bag with more tissue paper. It was tested several times at home with success. 

Egg Drop #STEM Challenge for kids-54

Unfortunately, the padding was not done the same as it had been prior, and the egg did not survive the official drop.

Egg Drop #STEM Challenge for kids-8

Someone’s dad might be a little upset this summer when he realizes a few car sponges are missing from the garage. Originally this creation had a parachute added, but it needed to be removed because of size requirements.  The sponges were glued together and a small space was hollowed out in the middle to house the egg. 

Egg Drop #STEM Challenge for kids-23

This one was a definite success, even after multiple bounces when it landed – and HIGH bounces at that!

 

Overall, this was such a FUN time with the kids and a great way to end our semester class together. Have you ever done an egg drop with your co-op class or kids at home? If not – have some fun and see who can come up the most creative idea!

Build an Alarm – Electronics for Kids

Apr72016
April 7, 2016 by Leave a Comment

build an alarm - electronics project for kids

Apparently Zachary has something special that needs protecting from his dangerous siblings or the animals roaming in our woods. He had the option of creating a door alarm, but decided instead that his cash box needed more protection. Using our most recent EEME kit, Project Tentacle, Zachary worked to build an alarm using electronics.

Over the past six months, Zachary has learned so much about bread boards, resistors, capacitors, and how to get his wires crossed (or not). It has been a fabulous learning time for him and something he has soaked up and absolutely loved.

IMG_6986

While we made a suggestion to not label his cash box, the alarm he built using the lessons from EEME were clearly a better option (grins). The alarm system using Project Tentacles was definitely a more creative option for his cash protection, and again Zachary learned more about circuits and different components, including NPN transistors – this was fun for me to learn as well, and you’ll hear more about it in the video clip below.

Building an Alarm – The Process

Contents for building EEME Project Tentacle

Because we have worked on several other projects from EEME, we had a few of the key components already on hand: a power supply and a breadboard. Otherwise, we received the following items in our kit:

  • buzzer
  • 2 – 6+” long white wires
  • 2 – 2” yellow wires
  • 1 – 1” blue wire
  • 2 resistors: orange band
  • 1 resistor: blue/green band
  • 2 3-prong transistors

I’ll be honest and tell you, the name of the project scared me a little bit at first! Fortunately, it wasn’t anything that involved lots of legs and crawled around the house – although the finished project did have some long wires that were all over the place.

IMG_6992

Zachary has a much better understanding of circuitry now that he has completed three projects with EEME, so it didn’t take him as long to complete this project overall other than figuring out the best way to ‘rig’ his cash box with an alarm and make it work every time the box was opened (a little duct tape goes a long way).

A Peek at How the Alarm Works

 

Zachary did a great job explaining the different components and how his alarm worked (ignore that I called the base a breadbox, please? I do know better than that!). Feed readers can click here to watch the video.

 

review questions

One thing I really appreciate about the projects from EEME is the constant review between the video clips. Some are review from the lesson while others are overall electronic questions based on what they have learned throughout.

You can see the three other projects we’ve worked on here:

Jellybean and Toothpick Structure STEM Challenge

Apr62016
April 6, 2016 by Leave a Comment

Jellybean and toothpick STEM challenge - building a structure that supports weight

For one of our most recent STEM classes at co-op we took advantage of Dollar Tree jellybeans and an overabundance of toothpicks. The kids have had so much fun with our hands-on challenges and learning about the best ways to build structures that are weight bearing and can stand a little pressure.

IMG_6948

Initially we divided up into four teams of 2-3 students each but gave the kids the option of combining with one other team to build their jellybean and toothpick structure. The kids decided that was definitely the better option and quickly moved together. They also realized it provided them with more jellybeans for eating, should they not used two entire bags for their structure (smart kids).


IMG_6951

One of the BEST things I heard came immediately after the kids combined (and while I eavesdropped on their strategy talk). Both teams were discussing the best way to build a structure that would support the most weight and still have a good height. From each team, the words “a triangle allows the strongest support” was heard. (Yes, they are listening!!)

IMG_6952

KEVA Planks were used as a sort of ‘holding pen’ for one of the teams – they didn’t want to risk floor contamination of jellybeans that may possibly be edible later. The other team obviously had no regard for where their beans ended up.

IMG_6955

IMG_6947

Both teams worked with a triangular setup for their structures, although one took a more systematic approach, setting up an assembly line of sorts. Team members started the process of putting a toothpick into a jellybean and creating piles, while others created pre-made triangles for another team member to work into their structure.

 

IMG_6953

Overall both teams had a blast with this challenge.  One structure was definitely more organized and that may be the team that wasn’t distracted by eating jellybeans along the way. 

IMG_6954

While Team 1’s structure was taller overall, it came to a definite peak and would not support as much weight when added (we stacked file folders on each structure to see how many it would hold). Team 1 eventually lost their triangular structure as their building continued( see the note on jellybean consumption), lost focus, and that ended up being their downfall.

IMG_6960

Team 2 had a much wider and elaborate base design (neater overall) thanks to their assembly line process. While their structure didn’t reach quite as much height as Team 1’s design, it supported more than twice the weight since it was able to more evenly distribute the weight when stacked.

(And jellybeans were consumed by all).

Such a fun and sticky challenge. Incidentally, picking up a box of 500 toothpicks that are spilled can be pointy and painful.

Bouncing Egg Science Experiment – Dissolving Calcium Carbonate with Acid

Mar242016
March 24, 2016 by 2 Comments

bouncing egg science experiment from Homeschool Creations

Before you go and think I’m crazy nuts, our bouncing egg science experiment involved a safe acid (grins). Zachary has loved all the hands-on projects to go along with his Christian Kids Explore Chemistry this year, and this one to see how acid interacts with calcium carbonate was no different.

That said – it was super easy to pull together and one that every family should do (did I mention it was easy?). Aside from learning about chemical reactions, what’s not to love about an egg that can bounce?!

Bouncing Egg Science Experiment

IMG_9595

The main purpose of this experiment was to test the reaction of a weak acid (white vinegar) with calcium carbonate (CaCO3 – an eggshell). If you’d like to try this at home, you only need a few items:

 

Here’s the quick science explanation:

An egg shell is made up of calcium carbonate, so when the egg is soaked in vinegar (about 4% acetic acid) a chemical reaction begins. Carbon dioxide is released (the bubbles you see on the shell) as the vinegar begins to dissolve the shell. The membrane of the egg will remain (the rubbery part of the egg).

 

IMG_9592

The egg was supposed to soak for 24 hours and then observations were to be tracked. Ours ended up soaking a bit longer (as in four days) because it stayed in the schoolroom over the weekend and we completely forgot out it. It was a lovely stink come Monday morning. (grins)

IMG_9606

The vinegar was carefully drained from the egg and GENTLY rinsed off under clean water. (May I stress gently again?)

IMG_9607

We pulled out another raw egg to compare and contrast to our experiment. The egg that had been soaked felt completely rubbery and could be gently squeezed (again with the gentle). The entire shell had dissolved thanks to the chemical reaction with the vinegar.

Size-wise there was a significant difference as well. When the egg soaked in the vinegar,  some of the vinegar and water in the vinegar moved through the membranes of the egg and into the egg. Egg membranes are semi-permeable so water can move through them (an example of osmosis).

 

IMG_9608

Trying to find the yolk now the shell was missing, we grabbed a flashlight as well to see how translucent the egg was. 

IMG_9616

The fun part came in the bouncing of the egg. To keep the counters clean, we pulled out a tray and tried dropping it from different heights to see if it would break.  You can see a short (and slightly blurry – sorry!) video here or below.

 

Once we were done bouncing and playing with the egg, we popped it with a fork to feel the membrane of the egg. (And yes, we all thoroughly washed our hands when we were done!).

IMG_9631

This is one of those experiments we would like to do again, but this time with several eggs in different jars and then try a few variables when we are done soaking them all in vinegar: moving one to plain water, one to cornstarch, and letting one sit out on the tray to see what happens to them all.

There’s so much more we could do, but this was a fun start to our egg experiments.

More Science Fun

If you have some time and need a few ideas, we worked on both of these projects this year and had a blast with them (especially the cookie skillet!).

Using Times Tales for Tricky Multiplication Facts

Jan202016
January 20, 2016 by 6 Comments

Educents is a blog sponsor and provided a digital copy of Times Tales for our review.

using Times Tales to learn multiplication facts

Multiplication facts have been a bit tricky for two of our kids, especially many of the ones in the 6, 7, 8, and 9 tables. Drilling wasn’t effective and was making life unpleasant.  Flash cards were not our friend.

Our fifth grader is constantly trying to sneak answers out of me, and although he eventually does get the correct answer when he thinks it through, recall isn’t as fast as it could be. Our youngest is beginning his multiplication journey, so over the last few weeks both he and his brother have been working together to learn their facts using Times Tales. Instead of groans and frustration, the two are learning together and remembering (without needing to ask me for help!).

As I’ve been sharing our progress via Instagram and Facebook the past bit, I LOVE hearing your comments and hearing how successful it’s been for your families also! I am so excited to share a more in-depth look at the program with you all. Be sure to read through as well, because there is a 15% off coupon code for you to grab!

How Times Tales Works

Times Tales animated math

Although it may seem like pictures and silly sentences, Times Tales is a digital video program that teaches the following multiplication facts using visual mnemonic stories: 3×6, 3×7, 3×8, 3×9, 4×6, 4×7, 4×8, 4×9, 6×6, 6×7, 6×8, 6×9, 7×7, 7×8, 7×9, 8×8, 8×9, & 9×9.

The program includes two DVDs or video downloads, each focusing on a set of problems: the lower facts and then the upper facts. Multiplication facts based on 0, 1, 2, 5, and 10 are not included in the program since children typically have an easier time learning those facts. DVD 1 covers the upper 3s and 4s times tables and DVD 2 covers the uppers 6s, 7s, 8s, and 9s.

Learning multiplication facts with Times Tales-5

Each number is given a visual clue to help children remember the prompt. We used the Times Tales download, so I transferred the videos to my iPad and the boys watched it together that way. We focused on Part 1 immediately after our break, waited two weeks, and then worked on Part 2 together. (Note: it is recommended that you work with the first DVD for at least one week before you begin the second.) We followed along as they recommend and the results have been FABULOUS!

Learning multiplication facts with Times Tales

Our oldest isn’t needing any help with his facts and able to immediately answer the multiplication facts – and has easily translated into division as well.

Here’s a quick look at the steps of the video (about 30 minutes each) and also a short video clip to show our boys ‘in action’ with the program.

 

 

 

 

Part 1

Learn the characters – kids are introduced to the different characters and the numbers they represent.

Part 2

Learn the Stories – Kids learn the multiplication facts by watching the short video story clips (less than 10 minutes).

Part 3

Beat the Clock – play a game and answer the questions within 3 to 5 seconds. The questions are based on the stories the kids learned in the prior part.

Part 4

Flashcard Practice – the problems/flashcards are shown on the screen and kids can either pause the video to answer, or let it run and see if they can beat the video. A division challenge is also included as a part of this section and kids see if they can guess who is missing from the problem.

There are also flashcards available as a part of the printable portion of Times Tales that can be printed off, both with prompts and as straight multiplication and division facts.

Final Step – The Written Test

Learning multiplication facts with Times Tales-7

In this step, kids work on the written tests that are included as a part of the program. There is a crossword puzzle challenge, a practice test (including the characters for visual clues), and also a full test with only the numbers and no clues.

What Mom Loves About Times Tales

times tales for learning multiplication facts

Other than printing things off to use later with the kids, there was really little that I had to do prep-wise for the boys. I did sit with them while they watched the video to observe what was happening. A few things I love:

  • The characters are memorable and ‘translate’ well. The boys haven’t had any problem learning or remember the numbers that each character represents or translating them to actual numbers for math facts.
  • The stories stick with you. Our girls used Times Tales years ago and were chiming in with the facts (and still remember them!). In the days following our first lesson with Times Tales, I would hear the boys stop for a moment in their math program and repeat one of the stories to solve a problem they were working on.
  • All the printables are included with the program. The only pesky part is putting the dice together (but I promise it isn’t that hard!). Otherwise you can save it to use with younger children and print off as many copies as you would like.
  • Two sets of flashcards help with recognition. For younger children, or those needing a little prompting, there are two different sets of flashcards included: one with visual prompts of the characters and one with the straight facts. Cards for division practice are also included with the program
  • It is a fun way to learn, rather than rote repetition. The boys have especially enjoyed this part and the more ‘hands-on’ aspect the program brought to math. Instead of pulling out flashcards, the boys enjoy rolling the dice to work on their math problems.

One reader emailed to ask if I thought the videos were cheesy. Now personally, I might not have thought our boys would like them, but since the clips were so short (30 minutes each), they were short enough to engage them while teaching the facts – and the stories stuck! Knowing the program works is a huge encouragement to me.

The day after we watched the second part of the Times Tales focusing on the upper multiplication facts, I pulled out the dice to see what Kaleb would remember. All we had worked on the day prior was the video itself and the practice test, with no review after that. Here’s a peek at how Kaleb did remembering the facts he learned:

 

 

 

 

I was really blown away! He gave the correct answers right away without even hesitating. For a boy that has only worked on his lower multiplication tables and not had any prior work with the upper facts – I was amazed!

Overall we have LOVED using Times Tales (and I may be a wee bit upset with myself for not pulling it out earlier for Zachary). It was a short time investment (and not a huge out of pocket expense either) for something that clicked with our kids and helped knock out something that was difficult for them.
