The Physics of Bridges
Stability is key when building a bridge. Scholars explore the forces acting upon bridges through an analysis of Newton's Laws and Hooke's Law. The activity asks individuals to apply their learning by building a bridge of their own.

Determination of Phosphorus Content in River Water
Divide your chemistry or environmental science class into two groups. Each group tests water samples from a river for the concentration of phosphorus using a different method. With chemists, you can use this activity as they learn to use...

A Scientific Investigation – What Types of Food Contain Starch and Protein?
You are what you eat, as they say! Are you more starch or more protein? Young scholars use their knowledge of each component to test different foods for their content. Using multiple indicators, individuals describe the protein and...

Studying our Senses
Who would not want an opportunity to taste jellybeans in class? During this investigation, life science learners hold their noses as they take a taste test and find that our perception of flavor is connected with our sense of smell. In...

Is There Salt in a Glacier?
What can conductivity tell us about a glacier? Groups analyze glacial melt to determine salt content through an analysis of the pH and conductivity measurements of two samples. Groups then determine the source of the salts.
