Acoustics: The Sound Lab
If the delay between a sound and its echo is less than 1/10th of a second, the human ear can’t distinguish it. Through the use of a Slinky, rubber band guitar, and straws, scholars explore where sound comes from and how it travels....
Cornell University
Polymerization
Explore condensation polymerization and additive polymerization through hands-on activities. Young scholars first model additive polymerization with paperclips. They finish the activity by using condensation polymerization to create a...

Enzymes: The Spit Lab
Enzymes in our bodies each have a job to do. Learn the factors that affect the activity of some enzymes using the third activity of an informative 12-part biology series. A three-part laboratory activity asks teams to investigate how...
Cornell University
Discovering Enzymes
Explore the function of enzymes through a series of lab investigations. Learners use household enzymes such as hydrogen peroxide to model the role of enzymes. The enzymes break down proteins with and without a catalyst.
Curated OER
The Atmosphere and Flight
Students investigate evaporation and condensation, and apply the concepts to understanding cloud formation.
Curated OER
How Many Drops?
Students 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
Snow Science
Learners investigate how efficient different substances are at melting snow. Students collect and analysis data.
Curated OER
Capillary Action And Transpiration
Students engage in a study of the concepts of biology with plants known as capillary action and transpiration. They conduct a simple experiment to demonstrate the concept. The lesson includes a background discussion led by the teacher...

Liquids Have Differnt Viscosities
Young scholars explore visosity of matter. They run tests of various liquid substances to observe and compare rates of flow of different substances. In addition, they relate viscosity to distance travelled by sample substances.
Curated OER
The Causes of Differences in Density
Students explore the causes of differences in density. Students choose objects, measure the mass and volume, and calculate the density of each. They perform additional density experiments to model atoms and their correspondence to...
