Learners build a solar oven from a cardboard pizza box, aluminum foil and plastic. Learners can use their oven to cook S'mores or other food in the sun.

In this outdoor beach activity, learners use a variety of "beaks" (such as trowels, spoons or sticks) to hunt for organisms that shore birds might eat.

In this activity, learners investigate the food, water, and space needs of common livestock animals.

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.

This activity focuses on interactions within Earth systems and the effects of human activities. In this activity learners build a biomass pyramid.

In this activity, learners discover that the Moon, like Earth, is made up of layers of different materials. Learners work in teams to make models of the interiors of the Moon and Earth.

In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.

Learners build a simple solar oven from a shoebox, black construction paper, and aluminum foil. Over the course of a few hours, the oven heats up water enough to brew tea.

This lesson will helps learners answer the question: How does the bombardment of micrometeoroids make regolith on the moon?

In this investigation learners explore the differences between, and interdependence of, living and nonliving elements in a water ecosystem.

This is a classic exercise for visualizing the scale of the Solar System.

In this activity, learners use the Sun's energy to cook marshmallows. Learners construct the solar oven out of simple everyday materials.

In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this activity, learners build models of comets, using edible materials, to learn about comets' structure.

This activity encourages learners to focus on the natural environment of the Eastern Woodlands before the arrival of European settlers.

Learners develop an understanding of air pressure in two different activities.

In this activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.
