Curated OER
Dose-Response Relationship
High schoolers complete their observations of germinating seeds. They create a graph showing all of their data and develop a dose-response curve. They compare their data with other groups and analyze the curves.
Curated OER
Investigation of Timbre
Students design an experiment to analyze the timbre of different instruments. In this physics activity, students analyze the missing quality in sound. They discuss their results in class.
