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

In this activity, learners explore the relative size of the Sun and Earth as well as the distance between them.

This activity (located on page 8 of the PDF) introduces learners to the concept of Non-point Source Pollution--what happens when rain washes garbage and other pollutants into rivers and lakes.

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.

In this demonstration, learners compare and contrast regular water ice to dry ice (frozen carbon dioxide). Both samples are placed in a solution of acid-base indicator.

In this activity and/or demonstration, learners illustrate visually and physically that air has weight. Learners balance two equally-inflated balloons hanging from string on a yard stick.

In this quick activity, learners observe how wind creates ocean currents.

In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.

In this activity, learners make a 3-D model of magnetic fields by inserting a small, strong magnet into a sphere.

Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

In this activity, young learners will model land and water on the Earth's surface to make a unique piece of "Earth Art." Activity includes materials list, step-by-step instructions, STEM connections a

Some bugs can walk on the surface of a lake, stream, river, pond or ocean.

In this activity, learners explore in what ways the shape of the land and the pull of gravity influence how water moves over Earth.

Learners will explore the concept of angular distance, and investigate why the moon appears to be the same size as the sun during a solar eclipse, despite the sun being much larger.

Learners discover that their breath contains carbon dioxide, one of the pollutants found in car exhaust.

The "Exploring the Solar System: Magnetic Fields" activity shows participants how scientists can use tools to study the invisible magnetic fields of Earth, the Sun, and other objects in the universe.

In this demonstration, learners observe the effects of density and pressure by attempting to make "balloon kebabs." Learners will try to insert a wooden skewer all the way through an inflated balloon

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.

In this activity, learners explore how distance can affect the way we perceive the size of an object.
