Build Your Own Hovercraft
Students construct a hovercraft following specific procedures. In this technology lesson, students explain the physics principles behind hovercraft. They compare and contrast this machine with the aircraft.
Curated OER
Physics and Me
Sixth graders compare and contrast mass and weight. For this physics lesson, 6th graders calculate speed given distance and time information. They construct a rocket and relate this to Newton's 3rd Law of motion.
Curated OER
Rock-A-Bye Pendulum
Third graders analyze the effects of force on an object in motion and its relationship to a change in speed. This lesson uses a pendulum to demonstrate the principle.
Curated OER
Trajectory and Range of a Projectile
Students investigate the factors affecting projectile trajectory. In this physics lesson, students calculate the range, time and speed of projectiles using mathematical equations.
Curated OER
Gel Electrophoresis
Students conduct a variety of experiments to explore gel electrophoresis. In this biology instructional activity, explain how this process separate DNA and RNA. They discuss the practical applications of this method.
Curated OER
Polymerase Chain Reaction (PCR)
High schoolers explore how PCR works through various activities. In this biology lesson, students explain how PCR generate copies of DNA. They simulate the process using an online interactive website.
Curated OER
Graham's Laws: Diffusion and Effusion of Gases
Students conduct a series of experiments to explore Graham's law. In this chemistry lesson, students differentiate effusion and diffusion. They perform calculations using Boyle's, Henry's, Charles' and Graham's Laws.
Curated OER
Rock-A-Bye Pendulum
Third graders use the scientific process to explore the effects of force on an object in motion. They demonstrate that the greater the force applied to an object, the greater the change in speed or direction of the object. They...

Incandescent Light Bulb
Students study the history of the light bulb and how an incandescent light bulb works. In this electricity lesson students complete several experiments on the light bulb.
Curated OER
Airplane Propeller
Students examine the different kinds of propellers and their functions. In this airplane lesson students build a hand made propeller.
Curated OER
Electroscope
Students examine what an electroscope is and who invented it. In this electrical instructional activity students build their own Emergency Radiation detector Electroscope.
Curated OER
Balloons
Students explore the different types of balloons. In this materials lesson students can complete several experiments including building their own hot air balloons, making balloon animals and experimenting with static electricity.
Curated OER
Investigation 4 - Collision Zone
Third graders study how forces of push and pull can change speed or direction.
