This is basic matter and chemistry information. Each part is a couple days to a week long worth of activities. Students can use this as a flipped classroom lesson, or more appropriate for homeschool students. This is not a full unit for teachers to just buy and use filling up a full 5 days of work no need to adapt! Again, it has been used for a flipped classroom and homeschool, so it is best used with teacher's added ideas to use in a regular classroom environment.
These can be adapted from 4th-9th grade I would say since science depending on state will hit many of these terms for state testing. Adapt to fit your kiddos. Don't forget to come back to see the other parts to create a full unit!
