You will need
Metal pie pan or other durable dish, tape,
measuring stick or tape measure
Here’s how
1. Place a metal pie pan upside down on
the floor. This is your bull’s eye target.
2. Place a piece of tape 10 or so feet away
from the pie pan. This is where you will
stand when testing out your catapults
and crossbows.
When you do the experiments with your
catapults, you should think about the
accuracy and precision of where the
projectiles land. Accuracy is how close
your results (or shots) are to your target
value — in this case, the center of the
target. Precision is how often you are
able to get the same value, or have your
projectile land in the same place. Look at
the pictures to the right to see how
accuracy and precision are related.
Accuracy and precision are both critical
concepts in the scientific world.
As you perform the experiments for each
model, think about how the changes
aect your precision and accuracy. Keep
a record of your results for the dierent
experiments.
