In this interactive board game, learners "hire" different types of scientists to help canine character Ruff Ruffman solve unusual problems.

In this activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.

In this activity about bones (page 12 of PDF), learners investigate and compare the weight-bearing capacity of solid and hollow cylinders.

In this activity, learners make and test fly paper helicopters. Learners use templates to create paper helicopters and then take take turns flying them in the air.

This lesson focuses on graphene and its electrical properties and applications.

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

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.

Learners create an electrical-circuit maze out of wire, then try to pass a paperclip through the maze without touching the wire.

Water treatment on a large scale enables the supply of clean drinking water to communities.

In this activity, learners construct a device that projects images onto a surface, so they can trace landscapes and other sights.

In this activity, learners concoct some stretchy green goo called Gak. This activity will introduce learners to polymers, chemical reactions, and how scientists invent new materials.

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

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.

In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

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

In this activity, learners use microarray technology to determine which genes are turned on and off at various points in the differentiation of pluripotent stem cells on their way to becoming pancreat

In this activity, learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

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 design challenge activity, learners build a four-stringed instrument that can play a tune.

In this activity, learners compare plant and animal life in different habitats including a sidewalk crack and lawn. Learners sort human-made materials and natural materials found in each habitat.
