Experiments

Students were instructed to bring in materials from home for their egg contraptions. After collecting materials over a period of a few days, students were able to work independently, in pairs or in small groups to design a contraption to protect their raw egg.

The objective of the lesson was to get students to investigate the relationship between mass and gravitational force. Another objective was to find out how potential energy is affected by height.

Students hypothesized and found that the higher the height from which the egg is dropped, the faster it will fall and the more force with which it will hit the ground. They also found that the greater the mass of the lander, the greater the gravitational force acted on the lander.

Therefore, a well-constructed egg lander is important!
