Learners follow a three-step process to start their own rock collection.

Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

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

In this activity, learners use cheap, thin plastic garbage bags to quickly build a solar hot air balloon. In doing so, learners will explore why hot air rises.

In this collecting/comparing activity, learners work with samples of sand from different places like a lakefront, river, or ocean beach.

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

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.

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

In this activity, learners will take a step back and learn the history of the land they live on, and the people who used to live on it.

In this activity, learners explore the different heating properties of soil and water.

In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.

In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

In this activity, learners investigate wind by comparing the force of wind in different locations. Learners build wind-o-meters out of wooden sticks and strips of paper.

Learners construct one or more of the following kinds of sundials: a shadow plot, a horizontal sundial, and a diptych sundial.

In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

In this outdoor, windy day activity, learners "fly" and race leaves along a line to discover which types of leaves catch the most wind. Which leaves are the best fliers? Why?
