As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.

In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).

Learners design their own experiment to determine conditions that either help or hinder the decomposition of carrots by soil microbes.

Agriculturalists have long considered mushroom growing a challenge, largely because you need a piece of benchtop equipment known as a laminar flow hood.

Learners use a transparent plastic glove as a container to grow seeds. A different kind of seed can be planted in each finger.

In this indepth hands-on activity, learners build a structure that allows them to observe the growth of roots and the correlation between root growth and stem extension.
