This is an activity about prediction. How far can you hop in 5 seconds? Could you make it to the door? Across the room? Everyone lines up and tries it.

In this activity, learners explore the concept of how aerospace engineering has impacted sports, specifically exploring the design of golf balls.

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 online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.

In this dramatic activity/demonstration about phase change and condensation, learners place an aluminum can filled with about two tablespoons of water on a stove burner.

In this activity (6th on the page), learners investigate how photoreceptors in the eye (rods and cones) "adapt" to low light conditions.

In this game (4th activity on the page) about hearing, learners test their ability to identify various sounds without looking.

On an airplane trip, learners have an opportunity to investigate the properties of air pressure at different altitudes.

In this activity, learners investigate whether more people are squares or rectangles. People with similarly sized heights and arm spans are classified as squares.

In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

Create a “Find Someone” list, with about 10 items, each containing a shape, number, or measurement. Can you find someone in the group with hair about 4 inches long? Someone wearing parallel lines?

In this online activity, learners find out whether they are smart enough to survive as a plant.

In this activity related to the famous "Stroop Effect," learners explore how words influence what we see and how the brain handles "mixed messages." Learners read colored words and are asked to say th

In this kinesthetic activity, learners will play a game with a ball to demonstrate the Coriolis force, which partly explains why hurricanes in the Northern Hemisphere rotate counterclockwise.

Exponga estos pósteres en el salón o déjelos donde los chicos los puedan explorar. Los chicos buscan las respuestas en línea, en libros de consulta, y en calendarios y almanaques.

This math activity exposes early learners to a variety of three-dimensional objects. Learners bring geometric solids (everyday objects) from home.

In this online activity, learners build their own system of heavenly bodies and watch the gravitational ballet.

In this environmental activity (page 6 of the PDF), learners identify household products that are recyclable and explore the different types of recyclable plastics.

This is a quick, yet dramatic activity/demonstration that introduces learners to the concept of energy transfer. A small ball is placed on top of a large ball and both are dropped together.

In this environmental activity (page 16 of the PDF), learners will calculate the amount of energy they save by recycling paper, plastic, glass, and aluminum materials over the span of a week.
