Science rocks.

Iceberg breaks in Antarctica not where expected: “With the dramatic crash of an iceberg against a glacier that dislodged a massive new chunk of ice, the mysterious continent of Antarctica once again did the unexpected.”

A big chunk of extra credit if you can figure out what happened and why it might matter (both for our studies of waves as well as the future of our planet’s climate). You’ll have to reflect back on our studies of elements, forces, pressure and waves.

And no… there is no “right” or “wrong” answer and you certainly can’t contain your hypothesis in one sentence, word or even paragraph

The Mariana Trench To Scale [Pic] | I Am Bored: “The Mariana Trench To Scale”

This is just too cool.

Remember, we know more about the surface of our moon than we do about the bottom of our oceans.

Yay Pascal!

Here’s the main point of our studies today on Work and Power:

- Newton (kg x m/s2) = Force
- Pascal (n/m2) = Pressure
- Joules (n x m) = Work
- Watt (j/s) = Power

Quiz tomorrow using these formulas.

Let me know if you have any questions!

Here’s your Homework for tonight (8.1, 8.2 and 8.3):

- 12.1 Section Review (p. 419) #1-5
- Simple Machines Quiz on material we reviewed today

Let me know if you have any questions!

On Thursday, we’ll be taking our test on Fluid Pressure.

Here’s your chance to suggest or vote on questions to appear on the test…

Be creative!

Next week, we’ll start our studies on “Fluid Dynamics” which is Chapter 11 in your book.

That’s just a fancy term for how forces affect fluids.

Sounds boring?

Nope, it’s fun. You’ll see.

How are Pascal’s, Archimedes’ & Bernoulli’s principal applied at a water park?? – Yahoo! Answers: “How are Pascal’s, Archimedes’ & Bernoulli’s principal applied at a water park??”

We’ll be taking Pascal, Archimedes and Bernoulli to the water park next week.

Bring your Dihydrogen Monoxide Coats!

Balloon Racers are due on Friday in class.

Make sure you know:

1) Your racer’s mass
2) The best set up for your balloon racer

If you’re in 8.3 and would like to try out a balloon racer, I’ll give some extra credit if you can successfully make the 5 meter challenge and figure out your racer’s mass, acceleration, velocity and force.

Fun article that explains how roller coasters work.

Give it a read!

HowStuffWorks “Roller Coaster Forces”: “To understand the sensations you feel in a roller coaster, let’s look at the basic forces at work on your body. Wherever you are on Earth, gravity is pulling you down toward the ground. But the force you actually notice isn’t this downward pull — it’s the upward pressure of the ground underneath you. The ground stops your descent to the center of the planet. It pushes up on your feet, which push up on the bones in your legs, which push up on your rib cage and so on. This is the feeling of weight. At every point on a roller-coaster ride, gravity is pulling you straight down.

The other force acting on you is acceleration. When you are riding in a coaster car that is traveling at a constant speed, you only feel the downward force of gravity. But as the car speeds up or slows down, you feel pressed against your seat or the restraining bar.”

I still think we need to take a class trip to Carowinds to put our new knowledge of forces to the real test!

Greetings from sunny Los Angeles (I haven’t seen many cardigans yet, but the butterflies did fly away).

I hope you all had a great Friday and finished up on those quizzes. Let me know if you had any trouble with them.

As you know, I won’t be in class on Monday either as I’ll still be here in the Sunshine State.

**So, please make sure you have materials you need to work on your balloon racers!**

I don’t have a formal lesson for you all on Monday with Mr. Ohlmer, but I’m sure you will know how to behave yourselves etc with the freedom of the activity (right?).

I’ll be back on Tuesday (hopefully) and we’ll start doing time trials to see your progress.

Get in touch if you have any questions over the weekend. I have my laptop, iPhone, Skype, Facebook, Twitter etc.

Good luck!
