DIY STEM Paper Circuits: Light Up Cards & GIVEAWAY

DIY STEM Paper Circuits: Light Up Cards & GIVEAWAYS

This STEM project teaches kids about circuits and electricity. Because there are tiny parts, I recommend it for ages 10 and older. This coincides nicely with 5th grade Core Curriculum circuits as well.

There are a few hurdles for doing this project. To make it easier for my readers to do this science project, I’m giving away some kits of the harder to procure parts. See the Rafflecopter below to win.

This Paper Circuit STEM project is also in Make: Start Making! A Guide to Engaging Young People in Maker Activities by Danielle Martin and Alisha Panjwani. I’m also giving away a copy of this book. To win this book, please leave a comment.

Step 1: The Materials

Some of the materials you’ll probably have around the house: clear tape, scissors, paper/card stock/construction paper (card stock is best), and binder clip (nice to have but not necessary).

3D Printing: Teen Makes His Own Invisalign

3D Printing: Teen Makes His Own Invisalign

Two of my kids are taking a 3D printing class this summer through Id Tech camp. My daughter’s orthodontist does not recommend making your own Invisalign as there might be issues with jaw alignment that requires more than moving your teeth.

Still, this college student, Amos Dudley, used a 3D printer to make his own Invisalign and successfully moved his teeth. My husband was impressed enough to send me this article from CNN Money.

He usedNew Jersey Institute of Technology’s equipment to scan and print models of his teeth, and mold non-toxic plastic around them to form the set of 12 clear braces.

STEM Science Project: DIY iPhone Microscope

STEM Science Project: DIY iPhone Microscope

I’m trying to do more science experiments with my son. We made a homopolar motor, learned about electricity with PlayDoh and LED lights, built a gamer remote control, made a 3D hologram projector, created a protective device for a raw egg, learned about the science of Ramune Japanese soda, and wondered why ice cubes crack in drinks.

I’m always looking for fun and easy science experiments so this DIY Phone Microscope got my attention. The video below made it sound easy: Read more…

Newton's 3 Laws of Motion for Kids Using Soccer

Newton’s 3 Laws of Motion for Kids Using Soccer

I remember how much I struggled in physics. It never really made sense to me. I didn’t want my kids to have this same experience so I thought I’d expose them earlier so that they would have a more intuitive feel for Newton’s Laws of Motion, the foundation of physics.

To make physics fun and relatable, I thought I’d use soccer to illustrate Newton’s three laws of motion. My son demonstrates here and there’s another animated cartoon below on Newtonian physics in space.

How about you? Do your kids gravitate towards the sciences?

How do mirrors work? How are mirrors made?

How Do Mirrors Work? How Are Mirrors Made?

PickyKidPix broke her full length mirror, not once but twice. I hope that’s not 14 years of bad luck.  She hated the replacement mirror that my husband installed and wanted to replace it, yet again, herself.

How do mirrors work? How are mirrors made?

This mirror drama got my son thinking and asking about how mirrors work. I was hoping that he could build his own mirror as a science experiment, but it turns out that mirrors are quite complicated to make.

How do mirrors work? How are mirrors made?

Here’s how mirrors work:

When photons — rays of light — coming from an object (your smiling face, for example) strike the smooth surface of a mirror, they bounce back at the same angle. Your eyes see these reflected photons as a mirror image. from Wonderopolis Read more…

Watch, Learn, DO: DIY STEM Summer Camp

Watch, Learn, DO: DIY STEM Summer Camp

“STEM Education Is the Key to the U.S.’s Economic Future” is what you read about all the time. U.S. News and World Report says:

We need to encourage more students to pursue science, technology, engineering, and math.

And what about girls and STEM? President Barack Obama has something to say about that (as a father of two girls, he carries some weight!):

“One of the things that I really strongly believe in is that we need to have more girls interested in math, science, and engineering. We’ve got half the population that is way underrepresented in those fields and that means that we’ve got a whole bunch of talent…not being encouraged the way they need to.”

5th Grade Rube Goldberg Science Project

5th Grade Science Project: Rube Goldberg Machine

I was talking to my business school roommate, Marc Parrish, the other day and he told me about his girlfriend’s son’s 5th grade science project (which seemed too advanced for most parents, let alone kids!). I blogged about my son’s 5th grade Cloud Science Poster so I was blown away that the elementary schools in Silicon Valley assign kids to construct a Rube Goldberg machine as homework.

No Trash Town in Japan

Earth Day: No Trash Town in Japan

Earth Day is coming up on April 22nd, and I was inspired by this video I saw on The Kid Should See This about a small town in rural Japan well on its way to becoming a zero waste community. This means that they will produce no trash. To this end, they sort their trash into 34 recycling categories. I know that my family and I have trouble with just one recycling category!

Coolest Star Wars Art Ever!

My son and I watched this and had the kind of reaction you get when watching an amazing fireworks display. Please watch the entire video as architect and artist Red Hong Yi has seven amazing Star Wars shadow art displays. She shines a beam of light from a specific position onto different shapes arranged on wires to get these effects!

Pair this with Tom Angleberger’s Origami Yoda series.
