Tomorrow, we’ll be having our test on fluid pressure. The key points will be: Archimedes’ Principle Pascal’s Principle Bernoulli’s Principle Please review those sections of your book and notes. Also make sure you’ve got the steps to the scientific method that we discussed in class today (Wednesday). Any questions?

Homework for tonight is: Page 402, #11-16 Please complete #1-15 on page 401 if you haven’t done so yet. Also, submit or vote on questions for our Pressure Test THIS THURSDAY.

We’re wrapping up our study of pressure including Archimedes, Pascal and Bernoulli next week. In the meantime, please do the following over the weekend: Page 401 #1-10 Also, start thinking about paper airplane designs

8.2: Compare Pascal’s Principle with Archimedes Principle. Know similarities and differences. 8.1 and 8.3: p. 397 #1-2 Homework will be checked tomorrow as a quiz grade. Here are a few helpful sites: Yahoo Answers on the 3 Pressure Amigos Comparison of Archimedes’ Principle, Bernoulli’s Principle and Pascal’s Principle Random Cool Facts See you tomorrow.

8.2: – Pressure Activity (4 questions, 2 Points) – 11.1 Questions on Page 378 (#’s 1-5) We’ll get caught up to 8.1 and 8.3 tomorrow. 8.1 and 8.3: – 11.2 Questions on Page 385 (#’s 1-2) – Quiz Tomorrow on Buoyancy

These are due in class 2/3/10… (MUST BE IN YOUR OWN WORDS!) – What does pressure depend on? – How do fluids exert pressure? – How does fluid pressure change with elevation and depth? – What is a pascal?
