Go Speedracer Go!

It's just amazing what you can learn using the Encyclopedia Britannica. In fact if you stack 4 or 5 of them, you can build a pretty cool ramp, great for exploring the concepts of motion. Get a couple of toy cars and you're ready to roll! Measure the length of the track, how long it takes each car to reach the bottom, and you've got everything you need to calculate their speed.


  1. Love that you found a good use for Encyclopedias!

  2. I've got nothing against encyclopedias, but I'm more of a World Book kind of a gal.
