In this activity (located at the bottom of the page), learners investigate soil and explore the creatures that live in it.

In this activity, learners explore how to protect their skin while applying pesticides to plants.

This activity shows you how to make a mold terrarium using a jar and leftover food.

In this activity, learners conduct an experiment to explore how water flows up from a tree's roots to its leafy crown.

In this activity, learners stain fabrics--on purpose!

In this environmental science activity (page 4 of the PDF), learners use vinegar and chalk to observe the effect of acid rain on various building materials and plant life.

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

In this experiment related to plant biotechnology, learners discover how to prepare and load an electrophoresis gel.

In this outdoor activity, learners release a portion of a lawn from human control—no mowing, no watering, no weeding, no pest control—and then investigate the changes that result over several weeks.

Learners make their own acid-base indicator from red cabbage. They use this indicator to test substances around the house.

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 chemistry challenge, learners work to figure out which of four juices are real, and which is just food coloring and sugar.

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

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.

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.

This activity provides an opportunity for learners to observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.
