Gravity Lab

Today we completed our first two full lab write ups. The first one was an experiment I designed, while the second they worked with a partner to design. This included a mini lesson on how to use spreadsheets to create graphs. 

Gravity
September 27, 2016

Purpose: Discover the relationship between gravity and falling objects.

Question: How does the shape of an object effect the speed at which it falls?

Materials:
1 box of Kleenex
1 ball

Procedure:
1.          Partner 1 climbs to the top of a playground structure.
2.          Holding each object in one hand, the items are dropped at the same time.
3.          Partner 2 records which one hits the ground first.
4.          Repeat 9 more times.
5.          Using the recorded data, create a graph of the results.

Data Collection:

Tissue Box
Ball

Results:

A tissue box and a ball were dropped from the top of a structure 10 times. The ball hit the ground first 1 out of 10 times. The ball hit the ground first 0 out of 10 times. They hit the ground simultaneously 9 out of 10 times.
