Learners discover the bubble power of living cells in this multi-hour experiment with baker's yeast. Learners make a living yeast/water solution in a bottle, and add table sugar to feed the yeast.

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, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

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

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

Learners grow sugar crystals (rock candy). They make a hot solution that has an excess of sugar dissolved in it, then as the solution cools, they see sugar crystals form.

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

This is a fun activity about the power of the Sun and the importance of using sunscreen to protect your sensitive skin from its rays.

In this activity, learners compare frog eggs to chicken eggs to better understand why frog eggs need water. Learners compare a boiled chicken egg to "frog eggs" represented by boiled tapioca.

In this activity, learners try to revive wilted celery. Learners discover that plants wilt when their cells lose water through evaporation. Use this activity to introduce capillary action.

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.
