In this Cyberchase activity, learners make decoders to send and receive secret messages. Learners make the device out of two 8-ounce cups and two code strips.

In this simple and fun activity, learners build a tower of cups to explore distribution of weight. Learners make predictions about their towers and test their designs.

In this simple and fun activity, learners discover the relationship between vibration and sound by making a squeaky toy instrument out of simple household materials.

In this activity, learners discover that they can create a lens from a water drop. Learners test their lens by looking at words or pictures.

In this activity, learners work together to interpret an "alien message." The group pretends that this is the only message from an imaginary civilization, so there is no "key" and thus no "correct" wa

What keeps bubbles and other things, like airplanes, floating or flying in the air?

Use grape juice, baking soda, water and vinegar to make acid and base indicator paper! This activity contains a recipe and instructions for the indicator paper.

In this activity, learners explore and experiment how we can use our bodies everyday to get from one place to another.

In this coin math activity, learners sort and stack 100 (one hundred) pennies into piles of 5 pennies each, 10 pennies each, and 20 pennies each.

Is this activity concentrating on physical science, learners build their very own miniature hovercraft out of a paper cup. Using it, they can explore the concepts of friction and force.

In this activity, learners play a card game that explores the relative sizes of various objects. Learners compete to organize their hand of cards into lists of objects from largest to smallest.

In this activity, learners explore the relationship between cooling water vapor and condensation. Learners investigate condensation forming on the outside of a cold cup.

This activity is a fun way to show two stages in a Monarch butterfly's life cycle. Learners will create an optical illusion that can be flipped from caterpillar to butterfly.

How many colors make black? Gather as many water soluble black markers as you can find.

Learners create an Incan counting device called a quipu (pronounced kee-poo).

Test the buoyancy of an aluminum foil boat and an aluminum foil ball. Why does the same material in different shapes sink or float?

In this activity, learners will discover how our universe is continuously expanding.

Experiment with liquids of different densities and create liquid layers. For example, oil and water have different densities: oil floats on water because it is less dense than water.

In this engineering activity, challenge learners to build a tower out of 10 sheets of newspaper and 3 feet of masking tape, which can hold a golf ball balancing at the top.

In this activity, learners use tangrams ( 7-piece puzzle tiles) to assemble a variety of shapes. Tangrams are ideal for improving spatial reasoning and geometry properties.
