3. Description Materials used Main Purpose
Wood, Fishing line, Hot Wheels Car, Razor Blade, Dominoes, 50 gram Weight
Main Purpose
To make the baseball roll off the table

4. Description cont. Sequence of Events Dominoes collide into car
Car rolls down ramp and cuts fishing line
See-Saw releases weight
Dominoes collapse and hit baseball, setting it into motion

5. Demonstration

6. Energy Conversions Step 1 – Domino Sequence
Conservation of Momentum
Step 2 – Car rolling down ramp
Conservation of Energy
Step 3 – See-Saw releases weight which hits dominoes
Conservation of Energy and Conservation of Momentum
Step 4 – Dominoes collide with ball

7. Conclusions Problems during building process We learned…..
Designing the ramp so the razor blade wouldn’t hit the bottom of the track
Efficient testing because retying the fishing line took a lot of time
Domino setup at the end… wouldn’t set ball into motion
We learned…..
Names are hard
