In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.

In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

In this activity, "write" a secret message in genetic code as beads on a string.

The goal of this activity is to design, build and test a house or toy for an animal.

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.

This is a game that is sure to sharpen players' basic math skills. Players must use four randomly selected numbers to create an equation that equals a fifth number.

In this activity, learners make a black box device that serves as an excellent analogy to Rutherford's famous experiment in which he deduced the existence of the atomic nucleus.

In this activity, learners explore the structural strength of triangles by creating their own free-standing geodesic dome out of plastic straws.

Learners build and investigate pendulums of different lengths. They discover that the longer the string of the pendulum, the longer the time it takes to swing.

In this activity, learners make different shapes that hold exactly one mole of gas (air).

In this activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.

Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

Learners use simple materials to construct a model the Big Dipper. Learners hang the model from a doorway or ceiling and look up at it to see the constellation as seen from Earth.

In this activity, learners use colored candy to represent subatomic particles and make a model of an atom (Bohr model).

In this activity, learners make their own encrypted code to pass along secret messages using a printable cipher wheel.

In this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).

This activity about cryptographic techniques illustrates how to accomplish a simple, but nevertheless seemingly impossible task—making a fair, random choice by flipping a coin between two people who d

In this activity, learners explore the relative sizes and distances of objects in the solar system.

In this activity, learners explore the great pump in their chests--the human heart!
