This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.

This lab activity has learners create a pendulum with a one-second period.

Groups of learners are provided with a generic car base and an egg. Their mission: design a device/enclosure to protect the egg on or in the car as it rolls down a ramp with increasing slopes.

In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.

The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

In this math lesson, learners analyze the density of liquids in order to explore linear functions.

In this math lesson, learners explore polynomial and rational function patterns.

In this math lesson, learners use the setting of a flower-making fundraiser to explore a variety of patterns. Learners examine the patterns in a flower design made of triangles surrounding a square.

In this math lesson, learners identify, describe, and construct the five regular polyhedra.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

In this activity, learners calculate the width (horizontal diameter) of the blind spot on their retina. Learners make a blind spot tester using a piece of notebook paper.

In this activity, learners discover how NASA engineers develop experimental aircraft.

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

Can gelatin (like Jell-O ®) change the speed of light?

In this activity, learners use a straight line to learn about circles. Learners measure and record the diameter and circumference of different sized cylindrical objects on a chart.

In this calculus activity, learners use a classic problem of geometrical probability to find an important mathematical constant (pi).

This activity helps learners learn about math through a real-world scenario. Three friends are baking cookies for their school’s bake sale.

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.
