## Sorting Materials by Properties

Instructions: What are some words that describe the two rubber rain boots? Can you describe their colors? Do you think they feel smooth or bumpy? Would they bend if you tried to pull them on your feet?

We can describe and sort materials by their properties. Color is a property. The boots are different colors. They could be sorted into different groups by their colors. Another property is texture. Texture is how something feels. The boots are smooth. They could be sorted into the same group because their textures are the same. Flexible materials can bend without breaking. The rubber boots would bend when pulled on. They could be sorted into the same group because they are both flexible.
