Learners display their findings after a study of surface area and volume. They build a mobile to show a commercially available box and a constructed cubical box of the same volume.

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

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

In this math puzzle game, learners work together to use algebraic reasoning and fun clues for solving word puzzles.

In this activity, learners use their feet to estimate distances. Learners calculate the distance of one step in centimeters by measuring 10 steps at a time to reduce measurement error.

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 will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this activity, learners follow simple directions to explore and create platonic solids.

Using paper, paper clips, an index card, and tape, teams of learners design flying devices to (1) stay in the air as long as possible and (2) land as close as possible to a given target.

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.

In this math activity, learners play a card game to practice adding coins quickly, just like a banker. First, learners create coin cards. Next, the cards are dealt to each player.

These puzzles use four colors of socks in a drawer to get learners thinking algebraically.

Learners determine the surface area and volume of two identical boxes, and then figure out the dimensions of a cubical box with the same volume.

In this math lesson, learners explore linear patterns, write a pattern in symbolic form, and solve linear equations using algebra tiles, symbolic manipulation, and a graphing calculator.

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

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

In this activity (on page 2 of PDF under GPS: Sea Turtles Activity), learners will model how a sea turtle population changes over time, from eggs to adults, using puffed rice.
