To Float or Not to Float - A Lesson on Density
Students define density in their own words. In this physics lesson, students calculate density using mass and volume. They explain why some objects sink and some float.
Curated OER
Current Interactions
High schoolers design an experiment to see how wind, temperature, and salinity work together to influence ocean currents and present it in a report format. They explain to their classmates how experiment findings relate to ocean currents.

Einstein's BIg Idea
Pupils discuss what the m in E=mc2 represent. They relate that mass in a chemical reaction is always conserved. Students convey that atoms rearrange themselves in chemical reactions to form different molecules and compounds.
Curated OER
Where's the Evidence?
Eighth graders observe evidence of chemical reactions. In this chemical reactions instructional activity students study chemical processes and complete a lab activity.
