Merry Christmas

I'm not sure how many people actually look at this thing. If you are one of the few I would like to wish you a Merry Christmas. I will have semester two work posted after the new year.

End of the Semester

The test Monday on Forces of Fluids didn't go so well. I don't know if it was the way it was presented or just a Monday test issue.

We began studying simple machines this week as well as discussing work and power.

Exemption notification is due on Monday so grading for my class is shut down today. We will take the December EOM test next Wednesday. Semester exams will be on Thursday/Friday.

Thinklink results were returned this week from the testing last month. Overall scores were about what was expected for a predictive assessment test. Ask your child about their results or you may email me.

Forces in Fluids Extra Notes

Pressure-the force per unit area exerted on an object.

Buoyancy- the ability of a fluid to exert an upward force on an object immersed in it

Archimedes Principle- the buoyant force on an object in a fluid is equal to the weight of the fluid displaced by the object.

Pascal's Principle- states that pressure applied to a fluid is transmitted unchanged throughout the fluid.
Ex. toothpaste
hydraulics

Bernoulli's Principle- as a velocity of a fluid increases, the pressure exerted by the fluid decreases.
Ex. airplane wing

Gas Laws

Boyles Law

Charles Law

Week of December 1-5

We are beginning to focus on Fluids and Forces of Fluids. This is Chapter 12 in their book but I'm not a big fan of books.
Monday-Computer Lab
Tuesday-Intro to Fluids (reviewed key concepts of states of matter, pressure, density) Introduced Boyles Law and Charles Law) HW: Chp 12 key terms and self checks
Wednesday- Continue discussion of fluids: Archimedes Principle, Bernoulli's Principle, Pascal's Principle. HW: (probably) 3 worksheets
Thursday- Review Game/Possible lab.....
Friday-Test (They really need to study their notes)

Next week we will cover Simple Machines.
