In this activity, learners create a soil and water model of a single-cell life environment and study living microorganisms.

In this activity, learners will explore vegetative propagation while preparing food scraps to grow into plants.

Learners use a universal indicator to test the amount of sodium hydroxide needed to change the pH of plain water compared with the amount needed to change the pH of gelatin.

Learners combine different plant solutions -- made from fruits, vegetables, and flowers -- with equal amounts of vinegar (acid), water (neutral), and ammonia (base).

In this four-day activity, learners grow bacteria and/or fungi from a variety of locations and compare the results.

This activity provides an opportunity for learners to observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.
