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.

In this activity, learners investigate convection by using food coloring and water of different temperatures.

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

In this activity, learners review and discuss weathering, erosion and mass wasting, to gain a stronger understanding of how Hickory Run’s Boulder Field was formed after the Laurentide Continental Glac

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

In this activity, learners investigate carbon sequestration by creating a carbonated beverage out of apple juice and dry ice.

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.

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.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.
