Grade Level: 6th

Subject: Science

Time Frame: 8 weeks (April/May)

​

Essential Questions

​

- what is a chemical change?
- what is a physical change?
- what is the charge of a proton, neutron and electron?
- what is an ion?
- what are nucleons?
- what is a chemical bond?
- what is a spontaneous reaction?

- describe spontaneous and non-spontaneous reactions
- create a photosynthesis equations

​

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

​

- explain why physical changes are reversible
