This CoolStuff post leverages a unique low-tech approach that allows students to leave their first day of class with the memorable experience of creating a model to explain their hypothesis.
Kinetic Energy and Velocity
Kinetic Energy and Velocity
Walk through an introductory physics lab that allows students to develop a model for the relationship between an object’s kinetic energy and velocity.
Forces and Motion
Forces and Motion
This CoolStuff post describes an introductory physics lab that allows students to develop a model of the relationship between an object’s acceleration and its mass using Newton’s 2nd law of motion.
Understanding the Relationship Between Mass and Weight
Understanding the Relationship Between Mass and Weight
This introductory physics lab helps students separate the concepts of mass and weight and uses experimental data to build a model of the relationship between the two variables.
Representing Motion (Constant Velocity)
Representing Motion (Constant Velocity)
An easy way to introduce students to some of the different representations of motion is to have them investigate the motion of a Constant Velocity Car.
