Matter and Its Interactions

Grade Level: 5th

Subject: Science

Time Frame: 3 weeks (August/September)

​

Essential Questions

 

- What is matter and what is made of?
- what happens to the mass of matter as it goes through its different forms (solid, liquid, gas)?
- What are the identifiable properties of a substance?
- When two substances are mixed together, is something completely new and different always made?

​

By the end of the unit, students will know:

​

- matter is a term that applies to all of the stuff around us and it is made of particles that are too small to see
- when substances are heated, cooled, or mixed the total weight before and after is always the same
- substances can be identified based on observable and measurable properties 
- sometimes when two substances are mixed, each of the substances keeps its original properties and sometimes a new substance is formed

​

By the end of the unit, students will be able to:

​

- give an example of what is matter
- describe how gases are made from matter particles that are too small to be seen. (ex: an inflated balloon)
- measure and graph the weights of matter before and after being heated, cooled, or mixed
- identify materials based on various observable properties
- determine whether the mixing of two substances always results in the formation of new substances or not and provide examples
- identify the differences between soluble and insoluble solutions
