Investigating ecosystems, matter, and energy through hands-on experiments and observations.
Water, air, and soil are essential to life in every ecosystem. Scientists study these to understand how they help plants and animals survive.
All living things need water. It can be found in rivers, lakes, oceans, and even underground.
Air is all around us! It contains oxygen for animals to breathe and carbon dioxide for plants to use in making food.
Soil is more than just dirt. It holds nutrients, water, and tiny living things that help plants grow.
You can observe water, air, and soil by:
These experiments help scientists (and students!) learn about our world.
Testing different soils to see which helps plants grow best.
Observing bubbles in water to learn about air.
Water, air, and soil are natural resources that support life and can be explored with simple experiments.
