The purpose of the Rubber band lab was to see how much force was needed to stretch the rubber band a certain distance. We used the force probe to tell us the average force. The amount we stretched the rubber band was 1cm, 2cm,3cm,4cm, and 5cm.
The Big Questions:
How can we store energy to do work for us later?
How does the force it takes to stretch a rubber band depend on the
AMOUNT by which you stretch it?
We can store energy to do work for us later by stretching out the rubber band with more force. The further you stretch out the rubber band means that it will require much more force. To stretch the rubber band 1 cm, it only took .58 N of force, but when we stretched the rubber band 5 cm, it required 3.15 N of force. As you can see from these two examples from the lab, this shows the relationship between how far you stretch the rubber band to the amount of force is needed.

Graph/ Data Table
The whiteboard shows the data table of the rubber band lab. The graph shows the increase in the amount of force needed to stretch the rubber band further. Also included on the white board was a data table that showed the amount of energy used (J) and the displacement at equilibrium(X). The equation F= kx was used to find the energy.
Real World Connection:
The Rubber Band lab connects to the real world especially when talking about slingshots. Slingshots relate to the lab because when you pull back the rubber band, the rubber band will fly out which is what a slingshot does with an rock/pebble. The further you stretch out the rubber band, the more force will be needed.
