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

In this activity, learners explore how engineers work to solve the challenges of a society, such as efficient planting and harvesting.

This laboratory exercise is designed to show learners how DNA can be extracted from a chunk of thymus (sweetbread) or liver.

When was the last time you took a really close look at a leaf? In this activity, learners will use leaves and simple materials to make colorful leaf rubbings.

In this highly collaborative activity, learners design and complete a controlled experiment which attempts to answer a simple question about the slime mold Physarum.

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

Using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, learners study the role of light in photosynthesis.

In this set of outdoor games, learners play the role of monkeys that are trying to get enough resources (food, shelter, and space) to survive.

In this activity, learners play an evolution card game to see how selective pressures can affect an organism's evolution.

In this activity, learners create a sealed, mini ecosystem that supplies freshwater shrimp with food, oxygen, and waste processing for at least three months.

In this cooperative learning activity, learners visit ten stations and are challenged to think critically about various conservation questions and issues.

In this outdoor activity, learners investigate spider webs and feeding behavior, particularly how spiders trap food in their sticky silk webs while not getting stuck themselves.

In this activity, learners explore how different deodorants work. Learners treat agar plates with different types of deodorants and compare the bacteria growth on the plates to the control sample.

In this activity, learners will discover what it takes to be a frog. By dressing up like one, learners can visualize how each part of the frog plays an important role in surviving its habitat.

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

Many germs spread by our hands, and often times, people don't wash their hands well enough to get rid of germs.

In this activity, learners will discover why there are holes in bread.

In this fun and in depth hands-on experiment, learners test various liquid samples (distilled water, lemon juice, vinegar, and baking soda mixed with water) to determine their pH levels and identify e

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

In order to examine the random nature of mutations and natural selection, learners "breed" clutches of Egyptian Origami Birds (Avis papyrus) using random number generators (dice and coins) to mutate s
