The Orange Game–Routing and Deadlock in Networks
How is data able to move in a congested network? Groups simulate moving data around a congested network by passing fruit around a circle, following specific rules, until everyone ends up with their own fruit. Extension activities...

Perceived Risks
Students rank a list of everyday risks to compare with classmates. They rate each risk on both its ability to be controlled and its observability in the environment. Results are graphed.

Sources of Potential Groundwater Contamination
Students construct models that demonstrate potential sources of contamination. Students select one type of contamination model (septic system, sinkhole, landfill, disposal lagoon, leaky barrels, oil spill, agricultural contamination) to...

Number Towers
Number towers use addition or multiplication to ensure each level is equal. While this is common in factoring, it is often not used with algebraic equations. Solving these six questions relies on problem solving skills and being able to...

Investigating Special Right Triangles
Scholars first investigate relationships in the side lengths of 30°-60°-90° triangles and 45°-45°-90° triangles. This knowledge then helps them solve problems later in the lesson plan about special right triangles.

Surveys and Estimating Large Quantities
Looking for an estimation activity a bit more involved than the typical "guess the number of jellybeans in the jar" game? Here, learners use a picture to estimate the number of people at a large event, look for potential problems with...

Determining Absolute Age
How can radioactive decay help date old objects? Learners explore half-life and radioactive decay by conducting an experiment using pennies to represent atoms. Young scientists graph data from the experiment to identify radioactive decay...

The East Fork Project
Students identify possible sources of health risks, types of exposures, routes of exposure, and populations that could be affected after discussing water pollution and environmental health hazards. After discussion, students conduct a...

Explore Subtraction
Learnersare given 26 tables and graphs in which they must fill in missing numbers and graph equations. They subtract a given value of x from a constant number, and use a number line to subtract larger numbers from smaller ones resulting...
