Young scientists explore the concept of surface tension at is applies to water. In this activity, learners use a dropper to place drops of water on a penny. Each group guesses how many drops a heads-up penny will hold, then conducts the...

Responsible farming is important for maintaining natural resources. Eager scientists complete a WebQuest to explore what happens to nitrogen when it enters the soil. They learn about the chemical makeup of nitrogen-based molecules...

Finding a balance between too much protein and not enough doesn't have to be a guessing game. Young scientists use an interactive lesson to learn how to calculate protein content in cattle feed and how to mix feed to create the ideal...

Taking the notion of symmetry to the next level, this looks at combining rotation and translation symmetry to build spiral symmetry in three dimensions. Using the Zome modeling system and an instructor’s guidance, geometers try to build...

Help learners determine the rate of change for the temperature of sand. They will collect data on the temperature of wet and dry sand over time with a heat lamp overhead. Then make a scatter plot of the data and find a linear model to...

Students investigate the relationship between volume and mass in different liquids such as vegetable oil, rubbing alcohol and water. They measure the mass of several different volumes of each liquid and then graph the results as well as...

Eighth graders experiment to determine the number of drops of water a heads up penny hold. They create a stem and leaf graph of the class results and use the data for further experimentation on a tails up penny.
