This exercise is designed to teach young learners the different parts of a plant (root, stems, leaves, flowers, fruit, and seeds), the basic functions of each part, and to show that tiny microscopic o

In this biology activity (page 3 of the PDF), learners will explore how plants turn sunlight into food through a process called photosynthesis.

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

In this activity, learners conduct an experiment to investigate the effect of elevated levels on CO2 on plant growth.

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

Over the course of several days, learners explore the property of water that helps plants move water from roots to leaves or gives paper towels the capacity to soak up water.

This outdoor activity (on page 2 of the PDF under SciGirls Activity: Sand Dunes) is a full inquiry investigation into how the amount of moisture in a sand dune relates to the number of plants growing

In this laboratory exercise, learners will discover how many different plant hosts they can find that are infected by the same genus of a powdery mildew fungus, or how many different genera of powdery

In this activity, learners create a biosphere in a baggie.

When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.

Water treatment on a large scale enables the supply of clean drinking water to communities.

In this activity related to microbes, learners make slides of cells from an onion skin and Elodea (American or Canadian waterweed) to observe under a microscope.

In this fun, hands-on autumn activity, learners experiment to discover whether the colored substances in leaves can be separated from the leaves.

In this activity, learners conduct a scientific investigation involving decomposition and discover that the life cycle of trash is affected by its organic or inorganic nature.

This lesson gives full instructions for making cabbage juice indicator, a procedure sheet for learners to record observations as they use the indicator to test materials, and extension activities to d

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.

In this activity (on pages 18-29) learners explore the impact of the March 24, 1989 oil spill in Alaska caused by the Exxon Valdez tanker.

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
