In this activity, learners see how many coins they can add to a full glass of water before the water overflows.

In this activity about weights and balances, learners create their own balance using paper cups. Then, learners explore how to compare the relative mass of objects.

Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.

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

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

En esta actividad la tira cómica muestra a los participantes como pueden hacer un experimento simple para ver cuales líquidos son ácidos.

Put a string around your head, and play it! Learn about vibration, sounds, and pitch.

In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.

In this activity, learners investigate convection by using food coloring and water of different temperatures.

Create a painting by blowing air out of a straw. Push liquid acrylic paint around on some watercolor paper by aiming short bursts of air onto the paint puddle.

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 design challenge activity, learners use tubes of newspaper to make a table that’s at least eight inches tall and strong enough to hold a heavy book!

In this introductory activity, learners discover that sugar and food coloring dissolve in water but neither dissolves in oil.

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 physics activity (page 14 of the PDF), learners gain a better understanding of how friction and mass affect objects by comparing the rotational inertia of raw and hard-boiled eggs.

In this activity, learners construct paper airplanes that twist and turn.

This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.

In this activity, learners explore Charles' Law in a syringe.

This fun astronomy activity allows learners to experience finding stars in the night sky that will eventually go supernova. This activity is perfect for a star party outdoors.

In this activity, learners create a hearing based memory game that they can share with friends.
