With animation, interactivity, and sound effects, Starting with Soil demonstrates how plants and animals cooperate to make the soil we need to grow healthy food. Kids learn that soil starts with bare rock and discover how long it takes nature to make one inch of topsoil. (Spoiler alert: it takes 500 years!) Different chapters convey the importance of pollinators and the critical roles animals, the weather, microorganisms, and cover crops play in organic farming. Designed for students ages 7-9, Starting with Soil allows users to plant seeds, build a compost pile, drag a microscope over different organisms in soil to get a better look, and view the symbiosis at work when corn, beans, and squash are planted together.
States of matter can be more than just your average solids, liquids and gases!
When water turns into snow, is it still water? The answer is yes! Our world is filled with solids, liquids, gases and even other matter that can go from one state of matter to another without changing its chemical substance. In this unit, students explore these different states of matter and their interactions. Students can make non-Newtonian fluids, observe how temperature and pressure affect matter, and explore solutions.
