It's day 2 of TINKERCLASS--Explore & Plan. You won't need to collect your own mischief of rats to explore and plan your project. Just your favorite stuffed animal or action figure and stuff you have around your house to build a car. This week's project features the Wow in the World episode, Rat Race!
