Example shows setup
with a ball in position
#1 and rubber band in
position #3
7. Initial Setup
2 shooters for
each team
1 ball
1 catapult
Fixed distance, about 5 to 8 feet
3 soldiers
8. Teaching Problem Solving
1. Setup & practice 15 min
2. Round 1 10 min per team
3. Problem Solving 60 min
4. Round 2 10 min per team
5. Reflection 30 min
9. Results
The Catapult Game’s
goal is to knock all 3
soldiers down every time
the shooter launches a
ball.
Results must be tracked
(in yellow) by teams and
by each shooter ( e.g.
shooter 1 and shooter 2
from team 1).
Points are assigned by
the number of soldiers
down. One point for
each solder knock down.
Each shooter tries 5 times at each round. The maximum number of points each
shooter can make at each round is 15 (3 soldiers multiplied by 5 times)
Example of scoring results for one team
