20 Best Tips

Building a Robot with EEME

EEME is a blog sponsor and we received this product free for the purpose of reviewing it. All opinions expressed are my personal, honest opinions. You can read my full disclosure policy for more details. 

Recently we shared Kaleb’s work on building Q the robot from EEME. Before getting to the finished (and fun!!) part of watching his robot move around, there were steps of learning about circuits, how motors work, and so much more. 

In short, a little bit of patience. 

The finished project though – so much fun to shut the blinds in the house, whip out the flashlight, and guide Q around the house! Especially when you see all your hard work pay off.

Q the Robot is a project kit that guides your child through the process of building a 3-wheeled robot who follows light. He is the first in a series of robotics projects from EEME – and there is no coding required to get started! Once completed, Q follows light around using two sensors, or photo resistors. When light is shined directly onto the sensors, Q turns to follow the light. 

Building our Robot

Using the FREE online lessons (anyone can view these!), Kaleb learned first about all the components that go into building this particular robot: breadboards and how circuits are completed, making the motors turn in different directions, powering the robot, photoresistors,  and finally had a chance to start building the actual robot. 

 

If you don’t know a thing about electronics, don’t worry. There are step-by-step videos that will walk your child (and you) through the process, and that includes explaining all the various parts and exactly what they do. 

We initially broke the video lessons for Q the Robot into three segments and over the course of three/four days: lessons 1-10, 11-20, and 21-35. Each of the 35 videos range in length, but average time each day was between half an hour to  45 minutes, taking us a little over two hours to complete the entire project. 

Our first step toward finishing Q was learning about photo resistors. The battery back was temporarily hooked up again with one of the motors to see how the circuit was completed and would function. You can see the photo resistor just to the right of Kaleb’s left hand. Later there will be two that will help “guide” the robot based on the light that shines on each resistor.

After learning about the photo resistors, Kaleb was finally able to pull out the main platform and start assembling the body for Q (lesson #26). 

The back of Q features a single caster that allows the robot to pivot or wiggle back and forth as it moves. 

The next steps (#27-28) may have caused a little more frustration for Kaleb. In assembling the motors and attaching them to the platform, it was a little trickier for him (he kept dropping one of the screws and missing the hole). 

Can I tell you what I loved at this part though? His utter concentration, shown by the tongue that stayed half stuck out of his mouth for the remainder of the building process. 

He was able to finally get both motors attached and labeled either right or left. The labeling is important for the turning of the wheels that are still to be added. 

The power switch and battery pack were the next to be added. We used some velcro dots (provided) to attach the battery pack to the platform – super quick and easy. 

At this point, Q the Robot was beginning to take shape nicely. While Q waited patiently, Kaleb completed a little more wiring. 

And finally the breadboard was mounted to robot body… 

motors were wired correctly (in complete concentration as you can see)…

And Q the Robot was finished! 

The best part though, after all this hard work, was seeing Q in action and having Kaleb explain some of it. Click to watch the video above (you can also visit and watch on YouTube). 

 

What Mom’s Need to Know…

  • Everything’s included – parts, wires, batteries are included in all every kit
  • No experience needed – our online lessons to mentor, guide, and teach your kid (seriously, this is a lovely thing)
  • Safety first – no soldering required, low voltage projects (the mom in me rejoices)

Meanwhile, kids are learning solid concepts and being challenged by building projects using REAL components. They may make mistakes, but in doing so, they learn to review and discover what they can do to make it better and work correctly. 

Perfect for ages 10+

Time Required: 1-2.5 hours

We’ve worked on several other projects from EEME. If you’re interested in learning more about their monthly subscription program, be sure to check out the below posts for more information:

Fun Hands-on Learning with Tinker Crate

It’s officially summer. And for our home that means that we’re spending a lot of time outside, at the pool, and have scaled back a bit from the lesson plans. 

However, that doesn’t mean that the homeschool learning stops during the summer. In fact, it’s the time that I especially try to provide hands-on learning opportunities to ward off the summer slump. 

Our boys are especially excited when they have things to build. Me, I’m excited when the lesson plans are already put together and I don’t have to do any prep. Tinker Crate offers the perfect fit for our family – a kit that includes everything we need (no shopping for me), detailed direction, and the chance for our kids to work on STEM projects and keep the learning going. 

Homeschool Learning with the Infinity Mirror 

Kaleb and I recently worked on the Infinity Mirror crate and had a fun learning about double sided mirrors and illusions. Overall, the project took us about 20 minutes to put together (I did have to help him a little bit). 

Tinker Crates are recommended for ages 9-16+ (Kaleb is 10), but even though he was on the lower end of the age range, he was easily able to follow along with the directions. 

What’s Included in the Tinker Crate

  • The full project – and all the materials you need to create
  • Your blueprint – how to put your project together
  • The Tinker Zine – more activities and learning opportunities
  • Links to video tutorials of all Tinker Crate projects

As a mom, I have to say that having EVERYTHING in the box is a huge help for me. There is nothing to cut out, trim, make “just right” – it is something we can literally pull out and start building. (This makes me happy!) I also love the terms they use to help kids get in the mode of tinkering – blueprints are still instructions, but they are setting the stage for the science and engineering that will happen!

Creating the Iris 

The first step in creating our infinity mirror was putting together the iris. This was one of the areas I had to help a little because it involved double sided sticky dots (and peeling the right layer off can be a little tricky at times). 

At first glance the iris doesn’t seem anything special – just a round circle, but it’s importance is shown once the second step of building the mirror is put into play. Basically, the iris will open/shut with a simple twist. 

Our completed iris took us about 10 minutes to put together – not too bad. All of the templates were included and Kaleb was able to follow the directions easily (both picture and written directions). 

Building the Lens

Once the lens was put together, we worked on the mirror component – and it was really interesting. One of the mirrors was a double-sided piece (allowing you to see through) and the bottom mirror (seen on top above) was a single sided mirror. 

Inside we had a component that we hooked up to a 9v battery and provided light inside when connected and the lens can be opened/closed by twisting the bottom section. With the lights lit, the two mirrors give the illusion that the inside of the lens is bottomless. 

When the light is off, the double sided mirror doesn’t allow any light through so you only see your reflection and nothing else, but when the light is on, the light is allowed through and the illusion begins. 

To give you a little peek, here is a 2 minute clip where we share our infinity mirror (feed readers can click here to see). 

 

A Little More About Tinker Crate (& Thoughts From Me)

Learning How to Make an Electromagnet – Project Attraction from EEME

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

IMG_7253

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

 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

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

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.
