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 nutrition activity (page 26 of PDF), learners consider the nutritional needs of people with specific dietary requirements, such as athletes, persons with diabetes and vegetarians, and create a

In this nutrition activity (page 16 of PDF), learners document their individual eating habits and learn whether their eating patterns meet their needs.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

In this activity about the relationship between food and energy (page 8 of PDF), learners estimate average daily baseline energy (Calorie) needs and energy needs for different levels of activity.

In this activity, learners make a solar oven. Learners witness the awesome power of the sun to make a yummy treat--a chocolate chip cookie!

In this activity, learners explore how engineers have developed big wheels or Ferris wheels.

In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.

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, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.

In this cooperative learning activity, learners visit ten stations and are challenged to think critically about various conservation questions and issues.

This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.

In this activity (on page 2 of PDF), learners create a low-tech refrigerator that requires no electricity to keep food from spoiling.

This activity (on page 3 of the PDF under GPS: Sailboat Design Activity) is a full inquiry investigation into design optimization.

Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black.
