Hi!

In Science we have been learning all about fluid pressure. Next Science class (which I think is tomorrow...) Mr. F will tell us about the summative assignment we are doing for this unit. So far we know that it has something to do with hydraulic systems and building something, so I'm guessing we are building a hydraulic system. Hydraulic systems are systems that use fluids under pressure to create movement. An example of one of these is a barber's chair. The air in the raising/lowering device is under pressure. When you press on the pedal, it opens up a hole at the top of the container the air is in. When a fluid is under pressure, the particles will all rush out quickly and with a lot of force if a hole is opened. So, that is what the air does. That force is applied to the chair, pushing it upwards. That's an example of a hydraulic system. I can't wait for our summative!

In Math have learned how to multiply fractions, and soon we will learn how to divide fractions and how to turn a fraction to a decimal and back again. I will keep you updated.

Until next Wednesday,
-K
