Curated OER
Scientific Inquiry: Periodic Motion
Students construct their own pendulum. In this physics instructional activity, students design an experiment to find the factors affecting its period. They formulate a conclusion based on experimental data.
Curated OER
Pure Substances and Mixtures
Students compare and contrast the properties of substances and mixtures. For this chemistry lesson, students simulate spontaneous mixing by performing a short class activity. They differentiate heterogeneous and homogeneous mixtures.
Curated OER
Projectile Motion: Hit the Army Men
Students predict the correct projectile launcher angle to hit the target. In this physics lesson, students record data on a spreadsheet. They curve their data and calculate the place of ball impact at an angle.
