Enzymes play a role in almost every function in the human body. Scholars explore three variables related to the use of enzymes. They observe a catalase reaction, experiment with substrates, and examine reactions rates. 

Second graders explore convection currents and how they relate to the movement of tectonic plates. Then, young geologists reconstruct Pangaea with a worksheet and pinpoint plate boundaries on a map...

Seventh graders investigate scientific methods to solve problems. They demonstrate creating data tables and graphs. They study the role of a scientist and the importance of safety in a science lab. They distinguish between an...

There is a solvent called aqua regis that can dissolve gold! After observing a solubility demonstration, groups receive four known crystals and one unknown. Based on the demo, they design an experiment to determine the identity of the...

Students are taught how to format and enter data into an Excel spreadsheet. They make a graph and interpret graphed data. Students discuss possible impacts of water chestnut invasion. They graph data on water chestnut. Students report...

Sugar isn't good for you, but it's great for yeast! Scholars design an experiment to investigate how variables affect the rate of sugar consumption in yeast. The last installment of a nine-part Life Science unit considers how scientists...

As an introduction to the skills required for and responsibilities of driving, pre-teens and teens engage in a series of activities, chart their response times, and analyze how variables effect these reaction times. Class...

Did you know that if you wait long enough, the M on the outside of an M and M will float to the surface when submerged in water? Learners observe the sugar coating of an M and M while it is dissolving in water. They explain how this...
