The thing i liked best about this unit was the labs.I did not like anything the least in this unit. A question i have is how does water expand but not freeze? In this unit i learned that a solution is two or more things mixed together to create one substance. I also learned that a mixture is created when two or more things are mixed together but can be seperated. Last i learned that a physical change is when something changes but can be recreated.  

This unit in science i learned how convection circulates in only liquids and gases.  I also learned how a microwave heats food using radiation and how conduction works. Something i liked best in this unit was the labs and something i liked the least was being the supplier and bringing water and supplies to the desks. A question i have is how does water expand?
