FLUIDS:
UNDER PRESSURE AND DENSITY LABS
Unit Overview
In
the last unit, Unit 21, we learned a lot about fluids. There were four main
concepts that we learned; density, pressure, buoyancy, and how fluid flows. In
this two-part unit we will explore density and pressure by manipulating a
simulation. The goal of this unit is to determine how atmospheric pressure
affects pressure readings in a tank of liquid. To establish a mathematical
relationship that allows one to determine the pressure in a liquid. And to
describe the changes which occur in a liquid when pressure is applied to a
liquid.

You
can download the lab to your desktop. It is wise to house all of the
simulations in a folder so you can refer back to them when needed.
Download the printable worksheet
below, you will use this to record all of your lab information. You will attach
your worksheet to question #6 in the question section.

A Look Ahead
In this unit we explored two of the four major concepts learned during our unit on fluids. The next unit is another laboratory exercise to explore the other two major concepts; buoyancy and fluid motion, all based on the content learned during unit 21. You will manipulate two different simulations to carry out procedures or design your own lab experiment using inquiry techniques.
Below are additional educational resources and activities for this unit.
