In this activity, learners predict where a ball will go after it bounces off another object. Learners discover that the motion of objects is predictable based on laws of motion.

In this activity, learners working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.

In this activity, learners construct a simple game to test their hand-eye coordination and steadiness of hand.

In this activity (on pages 13-16 of the PDF) learners investigate three mystery samples to see which one contains life. The three samples are sand, sand and yeast, and sand and antacid.

In this activity, learners discover if carbon dioxide has an effect on temperature.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

In this activity, learners play a game and use pattern blocks to explore mirror images and reflection.

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

In this activity about living things and gravity (page 5 of PDF), learners design and build an exoskeleton or an endoskeleton for an animal of their own invention.

In this activity about humans and space travel (page 1 of PDF), learners compare and contrast the behavior of a water-filled plastic bag, both outside and inside of a container of water.

In this activity, learners construct a paper glider to experiment with aerodynamic forces.

In this activity, learners build bridges using paper and explore how much weight each bridge design can support.

In this math activity, learners pretend there is a special store that lets you pay for toys by their weight in pennies.

In this math activity, learners experiment with the concept of symmetry.

In this weather forecasting activity, learners use common materials to construct a rain gauge and measure daily, monthly, and yearly rainfall.

In this quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.

In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

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