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.

In this activity (on pages 13-16 of the PDF) learners investigate three mystery samples to see which one contains life. The three samples are sand, sand and yeast, and sand and antacid.

In this activity, learners observe tide pool animals in a touch tank to consider how they survive.

In this activity, learners combine two substances (plaster of Paris and water) to make a cast of an object's imprint in clay.

In this activity on page 7 of the PDF (Chemistry—It’s Elemental), learners use iodine to identify foods that contain starch.

In this activity, learners mix milk, vinegar, baking soda, and water to create sticky glue. Use this activity to explain how engineers develop and evaluate new materials and products.

An outdoor scavenger hunt helps learners consider the theme of "What Is Life?" Learners explore what living organisms are, including how organisms meet basic needs of food, shelter and water to surviv

Learners explore soybeans, soak them in water to remove their coat, and then split them open to look inside. They also make a musical shaker out of paper cups, a cardboard tube, and soybeans.

In this experiment, learners test multiple food items to see if they are an acid or base using an indicator solution created with red cabbage.

In this hands-on science experiment, students combine their understanding of the different states of matter and the characteristics of various chemical reactions.

In this activity, learners discover if carbon dioxide has an effect on temperature.

In this experiment, learners separate different types of molecules in marker inks (using a technique called "thin layer chromatography").

In two separate bags, learners mix water with Epsom salts and detergent.

In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

In this activity, learners are invited to imagine the park of their dreams!
