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

To learn how friction affects motion, learners build a measurement tool from a rubber band and other simple materials.

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

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

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

In this activity, learners make a scale model of an atom to see how big or how small an atom is compared to its nucleus. Learners will realize that most of matter is just empty space!

In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

Learners attach an egg to a rubber-band bungee cord and drop the egg.

In this activity, learners listen to songs and decode hidden messages based on the same principle as a modem. As a final challenge, learners decode the binary messages in a music video.

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.

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 demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

Learners examine collisions between two skateboards carrying different masses. They learn about conservation of momentum in collisions.

In this chemistry activity, learners explore whether matter is created or destroyed during a chemical reaction. They will compare the weight of various solutions before and after they are mixed.

By tossing, collecting, and sorting beanbags, learners understand how the IBEX spacecraft uses its sensors to detect and map the locations of particle types in the interstellar boundary.

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

In this activity about how the body regulates blood pressure (page 117 of the PDF), learners make and compare measurements of heart rate and blood pressure from three body positions: sitting, standing

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