Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.

In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.

This is an activity that models the operation of a seismograph, a tool used to measure the size of earthquakes.

In this activity, learners create their own constellations and star patterns and write a short, descriptive story explaining the significance of their star pattern/constellation.

In this activity, learners investigate and compare the rate of drying in different conditions.

Learners compare the weight of equal volumes of wax, water, and clay. Learners discover that since the wax weighs less than an equal volume of water, it is less dense than water and will float.

In this activity, learners confront their perceptions of gravity in the solar system.

In this activity, learners model the gravitational fields of planets on a flexible surface.

In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.

This activity has three story puzzles learners can solve to learn about life in the Arctic.

This fun and simple hands-on astronomy activity lets learners explore model planets (that they or an educator will create), using methods NASA scientists use to explore our Solar System.

In this activity, learners design and build a NASA rover using raw pasta and candy with a limited imaginary budget.

In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.

In this activity, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.

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, learners map their world by drawing a plan of their bedroom.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.
