How Many Drops?
Learners conduct a simple test to determine how many drops of each of three liquids can be placed on a penny before spilling over. They come up with an explanation for their observations about different amounts of liquids a penny can hold.
Curated OER
The Cantankerous Pathogen
Learners explore what factors influence the spread of infectious diseases. They explain how human manipulation of the environment affects the transmission of diseases.
