In FE8B we started a new Math unit on proofs for angle degrees. It was kind of confusing to understand all the rules for the angles and how to write out the proofs, but now we have gotten the hang of it. Some rules we have learned about angles are: all opposite angles are equal, two or more angles that split a straight line (180 degrees) are called supplimentary angles, two or more angles that split up a right angle (90 degrees) are called complimentary angles, and that all three angles in a triangle equal 180 degrees. This is a very interesting unit.
In Science we also started a new unit on fluids. We have looked through the terminology for our new unit. Some of the words seem kind of confusing, but I am excited to learn about all of them.
Today we did a science experiment about the flow rates of some liquids. We put molasses, corn syrup, water, and vegetable oil through 4 different funnels and timed how long it took between the first drop of the fluid falling through the funnel to the last drop. This was really cool to see. The water took under a second to go through, the oil took 11 seconds, the corn syrup took 25 minutes, and the molasses took over 31 minutes!! I learned a lot, and thought it was fascinating to see the experiment right in front of us too, not just reading about what would happen in a text book.
Until next Wednesday,
