Today in Science class, we started off by
watching a video about how water reacts in space. We then continued to take
notes on how the terms mass, volume, and density describe matter. Every
substance has a unique density, you can even use density to identify an unknown
substance (EX- 2 liters of water and 2 cups of water WILL HAVE THE SAME
DENSITY, because it is the same substance). We started Chapter 3, Section 2
Changes in Matter. This chapter is about classifying changes in matter as
physical or chemical. A physical change alters the appearance of matter, but
DOES NOT make a new substance (ex- crushing, breaking, bending, dissolving).
The 3 states of matter are solids, liquids, and gases. Solids hold shape, and has
a fixed volume. Liquids fit to the shape of the container, they have a free
surface, and a fixed volume. Gases fit the shape of the container, and the
volume of the container. After, we went over the correct answers for the
Density virtual lab papers.
Social Studies:
In Social Studies class today, we first took time to look over our notebooks
before doing the notebook check. We then watched a documentary about the
Revolutionary War called “America: the story of us”, while answering questions
as we watched.
