Full speed ahead! Young learners conduct an activity using toy cars and ramps. They collect data on mass, speed, and time to investigate Newton's second law of motion. Ideally, they'll come up with the equation F = ma.

Students explore parts of a system. In this simple machines lesson, students discover that simple machines are composed of two or more systems. Students examine household tools and assess the parts of the system.

Students experiment in small groups to answer the question, "Is there a relationship between ramps and speed?" They apply a formula to calculate the speed of the cars used in the experiment, complete the associate lab report, and...
