In this activity, learners make pykrete by freezing a mixture of water and a material like cotton wool, grass, hair, shredded paper, wood chips, or sawdust.

This activity was designed for blind learners, but all types of learners can explore the process used to cast and mold molten metal, glass, and plastics.

In this activity (page 6 of the PDF), learners will observe both a chemical and a physical change.

This activity requires a Pico Cricket (tiny computer).

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

In this activity, learners explore how composites work by creating and testing their own composite for an imaginary company.

This three-part lab helps learners understand the essential principles governing diffusion and osmosis.

In this lab, learners evaluate the relative effectiveness of various chemical substances (i.e. garlic powder, bathroom cleaner, mouthwash, etc.) as antimicrobial agents.

In this activity (1st on the page), learners explore circadian rhythms by keeping track of their body temperature.

In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.

In this activity, learners discover how gelatin can be used as a medium for drug delivery. Learners create colored gelatin and then cut out pieces of the gelatin to simulate medicine (pills).

In this activity, learners cut wells in JELL-O© and load the wells with different detergent solutions.

This experiment allows learners to experience a small scale "epidemic," demonstrating the ease with which disease organisms are spread, and enables learners to determine the originator of the "epidemi

In this activity, learners investigate passive solar building design with a focus solely on heating.

In this activity, learners construct a simple electrolysis device. With this device, learners can decompose water into its elemental components: hydrogen and oxygen gas.

In a series of three experiments, learners explore the basics of biotechnology using self-locking plastic baggies. Each experiment demonstrates a phenomenon or principle of biotechnology.

Learners shred used paper, add water, and blend it into pulp. They then strain and roll the pulp out to make new paper.
