2. The Big Picture Computer mouse ball runs down spiral tube Through straight pipe Down series of ramps to control speed and add length Collision with Hot Wheels car Car launched down track Use Hot Wheels car to trip rat trap Rat trap rigged to disconnect wires that power speakers Speakers play music until disconnected

3. More Power! Gravity! (M*G*H) Spring (1/2*M*K^2) Chemical (Battery)

4. Equations

5. Design Challenges Ball tube Tape originally used, but didn’t hold Hot glue held much tighter Ramps Slats were glued at two precise angles to keep ball from rolling off & control speed One junction modified to correctly fit ball

6. The Sum of All Things Teamwork is Critical! Start at the end and work backward Plan to allow time for problems aka, start early! Troubleshoot each component separately Check and recheck for reliability Most of all… Have Fun!
