We learned that the 5 steps of the scientific method are:
1) Pose a question.
2) Make a hypothesis (an educated guess that can be tested).
3) Test the hypothesis.
4) Analyze the results.
5) Make a conclusion.
We wondered whether certain balls would sink or float. Given a tennis ball, golf ball, ping pong ball, marble, wooden ball, rubber ball, styrofoam ball, ball bearing, and a clay ball, we hypothesized about each ball's outcome. Then we tested them in a container of water! After taking data on a chart, we analyzed the results, finding that the tennis ball, ping pong ball, wooden ball, and styrofoam ball floated while the golf ball, marble, rubber ball, ball bearing, and clay ball sank. Lastly, we concluded that objects that were light, hollow, or had air pockets floated while objects that were solid, dense, and heavy sank.
