Water, along with soil and light, is a necessary component for plant growth. So what's better for promoting plant growth: tap water, or rain water?

Get a better understanding of water content by dehydrating carrots.

This science fair project teaches students about wilting and browning of salad greens.

This project is a vivid, concrete introduction to the basic but important idea that plants need sunlight and water to grow.

Why do plants wilt? Kids will learn to think critically about what environmental factors affect plants, and what plants need to survive.

This project explores whether plants can live and grow when "watered" with juice, soda, or milk.

Kids will learn how to clean fish tank the natural way. Add catfish to the tank and see if your water gets cleaner.
