Love This Site? Want to share it with your friends?
It’s simple! We’ve created a mini-eScience packet that you can download and forward to your friends. Inside this Science Activity Manual, you’ll find a copy of several super-cool experiments from the eScience website, complete with links to our most popular videos. We put this together because we’re needing help in our outreach department with offering free educational resources to homeschool families. We’re trying to give... [Read More...]
Unit 10 (Electricity) Teleclass Recording
Download the Unit 10: Electricity file here. Don’t forget – we didn’t record this track in a professional studio, so don’t worry if you hear pops, clicks, chimes, or other odd sounds – just focus on the real message and the learning that’s going on. Are you ready?? Read More →
Electrical Circuits & Components Exercises
Let’s see how much you’ve picked up with these experiments and the reading – answer as best as you can. (No peeking at the answers until you’re done!) Just relax and see what jumps to mind when you read the question. You can also print these out and jot down your answers in your science notebook.

Basic Circuits
An electrical circuit is like a NASCAR raceway. The electrons (racecars) zip around the race loop (wire circuit) superfast to make stuff happen. Although you can’t see the electrons zipping around the circuit, you can see the effects: lighting up LEDs, sounding buzzers, clicking relays, etc. There are many different electrical components that make the electrons react in different ways, such as resistors (limit current), capacitors (collect a...

Waterbots
ROV stands for Remotely Operated Vehicle. These robots are used by scientists to explore the waters both offshore and in the deep sea, and often bring back samples and/or take video of their underwater findings. ROVs usually have a tether from the vehicle to the boat, which lightens up the load quite a bit (as it no longer needs to carry its own power or data storage). Powerful motors, such as bilge pumps or 24VDC motors, enable this robot to move... [Read More...]
Jigglebots
Ever wonder how a cell phone vibrates? What mechanism could be in such a tiny space to make the entire phone jiggle around? Well, there’s a tiny motor inside with an off-center weight on the shaft, called an eccentric drive. You can still see eccentric drive mechanisms in older steam engines where the rotational motion is converted to liner? movement. Eccentrics are also found on tandem bicycles with timing chains. Kids can make this robot... [Read More...]
Conductivity Testers
Make yourself a grab bag of fun things to test: copper pieces (nails or pipe pieces), zinc washers, pipe cleaners, Mylar, aluminum foil, pennies, nickels, keys, film canisters, paper clips, load stones (magnetic rock), other rocks, and just about anything else in the back of your desk drawer. Certain materials conduct electricity better than others. Silver, for example, is one of the best electrical conductors on the planet, followed closely by... [Read More...]
