Essential Questions

 

- What are the different states of matter?
- How can we sort and classify matter?
- What materials are best suited for different purposes?
- What are the differences between a solid, a liquid, and a gas?
- How can matter change states?

By the end of the unit, students will know:

 

- Properties of different materials such as strength, hardness, flexibility, and texture
- what materials are best suited for different purposes
- an object build out of a small set of pieces can be deconstructed and build into a different object
- properties of solids, liquids, and gas
- some substances can experience reversible changes and some cannot
