4. What is matter?

5. How can matter be changed?

6. In what ways can you change matter?

Evaluation
Conclusion

In conclusion, matter can go through changes. Some of those are reversible, and some of those are irreversible. Irreversible means it cannot be changed back into its original form.

Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot.

Students will explore reversible and irreversible changes and draw conclusions on why and how they work. 

 

Disciplinary Core Ideas: CHEMICAL REACTIONS

Heating or cooling a substance may cause changes that can be observed. Sometimes these changes are reversible, and sometimes they are not.
