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 observe different plant-originated foods.

Discover how the salt in soil affects plant growth with a few seeds, some cotton, and salt. In this hands-on activity, you will plant seeds in 2 different kinds of soil, containing more or less salt.

In this biology experiment, learners plant soybean seeds in plaster of Paris, witnessing firsthand the mighty power and ability of plants to grow in adverse conditions.

In this activity, learners create a garden in a disposable glove. They learn about the conditions necessary to make the seeds sprout and actively participate in caring for their plants.

In this activity, learners will dissect a pumpkin or winter squash to learn the parts of the plant. This activity gets your learner hands on with every part of the plant and will be messy.

In this activity, learners draw natural objects to explore the details, differences, and similarities of natural objects.

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

This guide outlines how to plant a garden even if you don't have a yard!

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

In this activity, young learners will make their own flower seed nursery in an egg carton.

Learners create a model of a wetland to observe how it absorbs and filters water from the environment.

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 build one or more edible coral polyps and place them together to form a colony.

An estuary is a body of water that is created when freshwater from rivers and streams flows into the saltwater of an ocean.

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 use food scraps from the kitchen to grow new vegetables.

In this combination chemistry and physics activity, learners explore water absorption in dried beans or peas and learn how this affects their physical properties.

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

While playing a game, learners discover how the Endangered Species Act works in the United States. Learners move along a game board by answering questions correctly.
