Forces

Newton's Laws

​Using a simple lab set up to investigate Newton's Laws of Motion with wooden blocks and rubber bands

Net Force and Types of Forces

​Add mass to a helium balloon until it is neutrally buoyant and calculate the number needed to lift a house
​Introducing normal force by using a simple laser apparatus to show the flexing of a solid wall
​Walk Around activity with questions about net force and types of forces

Friction

​Using egg cartons to model and visualize friction between surfaces in contact
Using video analysis to estimate the coefficient of kinetic/dynamic and static friction for viral videos

Ramps

Introduce forces on a ramp by revealing that electronic balances don't actually measure mass
Using phone sensors to measure the slip angle and calculate the coefficient of static friction of a phone case
