In this activity (located in the middle of the page), learners start a garden by planting their socks!

In this food science activity, learners observe different plant-originated foods.

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

In this activity, learners plant seeds and watch them sprout and grow inside a CD case.

In this activity, learners identify the reproductive parts of plants and the animal (bee) structures involved in pollination.

In this hands-on botany activity, learners sprout vegetables in film canisters.

This exercise can be used to stimulate the investigative nature of learners as they use forensic plant pathology techniques to prove the learners' innocence in a mock murder investigation.

In this activity, learners investigate soil conditions by creating a soil map. Learners record soil characteristics and compare the conditions of soil in different grid sections.

In this activity, learners make three different "seed" types and determine which design flies the farthest.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

This activity (on pages 19-24) introduces learners to the rain forest's layers—emergent, canopy, understory, and forest floor—and has learners make paper lianas (vines that live attached to trees) and

In this activity, learners will design a seed and test how it travels. Learners will use the Engineering Design Process to create a seed which can move from place to place.

In this activity, learners discover which plants and animals have symbiotic relationships and how this impacts each organism.

In this creativity-based activity, learners imagine what the Earth will look like in the near and distant future, then design their own future habitat and creatures that may live there.

In this activity (p.25 of PDF), learners investigate spores. Mushrooms produce millions of spores which are equivalent to the seeds of plants but without the massive food reserves.

In this activity, learners explore the web of connections among living and non-living things.

In this family or group inquiry activity, learners use their senses to explore a local forest or woodland.

In this environmental science lesson, learners will examine hazardous chemicals and their effects on human health and the environment.
