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

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 environmental education demonstration (page 6 of the PDF), learners will see a tangible representation of the scarcity of soil resources on earth.

This activity demonstrates the importance of wearing a helmet to protect the brain. An egg is used to symbolize a head with the shell as the skull and the inside of the egg as the brain.

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

This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.

In this activity, learners count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.

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

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

In this activity, learners follow simple historical maritime recipes to cook up hardtack and swanky, and then compare the foods they eat to what was served on ships in the past.

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

In this activity, learners investigate the history and development of agricultural biotechnology.

Learners explore soybeans, soak them in water to remove their coat, and then split them open to look inside. They also make a musical shaker out of paper cups, a cardboard tube, and soybeans.

In this activity on page 8 of the PDF (Behind the Scenes with Chemistry), learners make three of Harry Potter's essential school supplies: quills, ink, and color-changing paper.

In this activity, learners use a model for how fishing affects marine life populations, and will construct explanations for one of the reasons why fish populations are declining.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

Learners work in groups to construct bridges using stale marshmallows and toothpicks.

In this activity, learners build one or more edible coral polyps and place them together to form a colony.

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

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