Creating the Ideal Cargo Boat
Students build boats out of clay to test the buoyancy of the boat in water. Students break into pairs and construct their boat to specific guide lines, then experiment with their boat in the water.
Curated OER
Column Chromatography
Students research the mechanics of liquid chromatography. In this technology lesson, students calculate the concentration of unknown samples. They write a report about their research and lab results.
Curated OER
Gravity Gets You Down
Learners design an experiment to investigate how objects with different masses fall. In this physics lesson, students predict how these objects will fall in a vacuum tube. They write a report explaining experimental results and conclusion.
Curated OER
Trajectory and Range of a Projectile
Students investigate the factors affecting projectile trajectory. In this physics instructional activity, students calculate the range, time and speed of projectiles using mathematical equations.
