In this unit I learned that there are many acids that wont hurt you. One thing I did not know what bases were. I also learned  about the Ph scale and how it goes from 0 to 14. One thing i really liked about the unit was all the projects we did and how much they helped me. the one I likeed the most is the acid or base on because it was cool seeing what were acids or bases.

In This unit i learned about heat and how it goes from a hotter object and then to a cooler object. I also learned about expanding and contracting. I learned how hot water the particles move a lot faster. I really liked the experiment's. i didn"t like anything about the lesson. I still do not understand conduction?
