Bacteria Change Earth's Atmosphere
Tenth graders organize information to explain how photosynthetic bacteria contributed to climatic changes that happened on Earth. Students create a timeline by using a storyboard to tell the story of the change.
Curated OER
Transmission of Disease
Young scholars provide names of viral diseases that they would possibly like to be infected with today; listing them on the Smart Board. They then come to an agreement about what virus to use and use beakers of fluids to simulate how...
