Build up from the previous activity where your learners charted the population growth and decay of a fish pond with M&Ms®. Have them look at the data from that activity and create a Now-Next, or recursive equations, to predict the...

Ever wonder how fish survive in freezing cold water—especially Antarctic waters? Some fish have an adaptation that lowers the freezing point of their life fluids. Learners model these adaptations in two lab explorations. The first...

A 27-page packet full of math games and activities builds on algebra, measurement, geometry, fractional, and graphing skills. Young mathematicians participate in math games collaboratively, promoting teamwork and skills practice.

Create clay whistles with your elementary or middle school students. The project is outlined in great detail here, complete with step-by-step photographs, finished examples, a materials list, student handouts, and a rubric. Students...

Your young apprentices build a function describing the percent concentration of salt in a brine. The rational function is then related to the parent function, y= 1/x, and graphed. Finally, the apprentices predict the amount of fresh...

Sometimes, taking things apart is more fun than putting things together. Groups of learners participate in a reverse engineering activity. They dissect a device of their choosing to see how it works—great hands-on learning from the...

Introduce learners to exponential growth with this real-world problem about algae that is rapidly spreading across a lake in a city park. The task presents the rate of growth and an end value and asks learners to determine what happened...

What is the best way to test water quality? Using plastic bottles, scholars create monitoring sensors to test water quality. Creating three different sensors allows individuals to measure water quality at different water levels.

Seven pages offer scholars the opportunity to learn about North American mammals and boost their coloring skills. Animals include brown bears, beavers, jackrabbits, wolves, jaguar, and Dall sheep
