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

In this activity, learners are challenged to eat some candy as a cell would need to as well as to think about some of the problems that arise when a cell ingests food.

This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.

In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.

In this activity about olfaction (7th activity on the page), learners use natural ingredients to concoct their own perfume.

In this activity (4th activity on the page), learners use their sense of smell to rate and arrange containers filled with different dilutions of a scent (like cologne or fruit juice) in order from wea

Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.

In this (edible) activity, learners balance chemical equations using different kinds and colors of candy that represent different atoms. Learners will work in pairs and explore conservation of atoms.

In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.

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

In this activity, learners make self-assembled polymer spheres.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

In this math lesson, learners explore the relationship between the thickness of a spaghetti bridge, the length of the bridge, and the amount of weight that can be supported by the bridge.

In this math lesson, learners model exponential decay and exponential growth using M&M's, paper folding, and African rhino population data.

In this activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.

In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.

In this design challenge, learners will use microbes to design and grow a custom biomaterial at home and make something creative with it.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

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