Curated OER
Scientific Inquiry: Periodic Motion
Students construct their own pendulum. In this physics lesson, 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
Learners compare and contrast the properties of substances and mixtures. In this chemistry lesson, students simulate spontaneous mixing by performing a short class activity. They differentiate heterogeneous and homogeneous mixtures.
