Matter comes in different forms: Solids, Liquids and Gases. A solid keeps its shape. A liquid takes the shape of its container. A gas fills its container.
Most of the water on Earth is found in the ocean. Fresh water is found in lakes, rivers, underground and in glaciers. Since there is so little fresh water on Earth, we should conserve it.
Plants need the right amount of water and light to grow best. Soil quality can affect how well plants grow. To find the best conditions you need to experiment.
Heating and cooling can cause changes we can see. Sometimes these changes are reversible and can be changed back. Sometimes these changes are non-reversible and cannot be changed back.
Some materials have properties best suited for certain purposes. In this lesson we will learn about stretchiness, absorbency and strength. Comparing different materials involves doing experiments.
A property is a quality or trait of something. To classify objects means to group them by their shared properties. We can classify objects based on properties like color, texture or hardness.
Maps show us where things are located on Earth. Physical maps can show us landforms. Political maps can show us the outlines of countries. Weather maps can show us weather in different areas.
