In this lesson students will observe and read about microorganisms so that they can create an information book on microorganisms.
In this lesson, students will design a model race car and use their model to investigate the relationship between the potential and kinetic energy of their model as it travels down a ramp. Students will also investigate how the acceleration of their model is affected by forces applied and the mass of their model. Students will be asked to identify variables that may affect the acceleration of their model and then design an investigation to test design modifications to reduce friction and air resistance. Students will collect data during their investigation and represent their data in graphs so that they can compare their data with that of their classmates. Students will communicate the results of their investigation and justify their final design choice based on the data they obtain in their investigation.
The objective of this activity is to reinforce the importance of being specific while dealing with events of a sequential nature, such as the phases of the moon.
