In this lesson, learners will practice graphing and statistically analyzing data.

In this activity (on pages 20-23 of PDF), learners build a model of a power plant using simple materials.

In this activity, learners use a fictitious map of "Tourist Town" and counters to problem solve how to place ice-cream vans on street intersections so that every other intersection is connected to one

In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

In this activity, learners explore dinosaur skeletons.

In this activity, learners design a device to solve a problem: how to get a ball out of a drain pipe.

In this activity, learners explore the size and scale of dinosaurs. Learners listen to "The Littlest Dinosaurs" by Bernard Most to learn about the different sizes of dinosaurs.

In this math lesson, learners determine and compare the rate of descent of various learner-constructed parachutes. Learners construct parachutes that will have maximum hang times.

In this math lesson, learners are given 15 chips and a number line labeled from 2-12.

In this activity, learners will explore trends in shark populations using shark landing data from the National Marine Fisheries Service.

In this math lesson, learners predict, interpret, and sketch graphs of functions related to the shapes of bottles. A measure of water is poured into a container.

In this math lesson, learners apply mathematical modeling to solve a real-world storage problem, in which a manufacturing company is given two options for storing oil barrels.

In this math lesson (page 2 of the PDF), learners use bottles of various shapes to explore the abstract concept of rate of change.

In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.

In this math lesson, learners explore the real world meaning of slope. Learners conduct a balloon experiment in which they measure the circumference and flight time of deflating balloons.

Learners participate in a variety of activities modeling different disabilities.

Learners explore soybeans, soak them in water to remove their coat, and then split them open to look inside. They also make a musical shaker out of paper cups, a cardboard tube, and soybeans.

Build a house you can fit inside, using cardboard tubes.

In this math lesson, learners apply the Monte Carlo method of simulation to determine a reasonable estimate.

In this math lesson, learners design an experiment to model a leaky faucet and determine the amount of water wasted due to the leak.
