Curated OER
How Do Scientists Research For Lab Activities?
Students explore the nature of scientific knowledge. They will also explore how to develop a lab plan to explain the structures of molecules and atoms. Research is essential to the success of the lab using necessary educational software.
Curated OER
Aurora Borealis
Middle schoolers discuss what causes the northern lights and the folklore attached to them. They discuss magnetic fields, and use various common materials to discover if ions conduct electricity.
Curated OER
Extraction of DNA from White Onion
Students conduct lab test with minced onion to determine where chromosonal DNA is located within the cell, and whether or not it can be extracted.
