Thank you for making all of your videos. When I was taking my test I really found everything you guys say. When we were taking the test I thought of what you said about atoms getting tightly packed together and what you said about liquids take its shape of its container and how liquids have viscosity. I also remembered what you guys said about gas spreading out when exposed to air.
I was also fascinated when you guys told us about matter changes and how important matter actually is. I also greatly appreciate what you guys said about how only the top of a lake will freeze, not the whole lake.
Also thank you for talking about physical changes, chemical changes and how the sugar was kind of melting, and also how the ice cream went through a change.
