BUOYANCY AND FLOW
Unit Overview
This
unit is designed in two parts. In Part I, you will manipulate a simulation to
explore properties of buoyancy. In Part II you will explore factors that affect
the velocity of a fluid. These are two very important concepts to understand
when dealing with fluids. In the last unit we looked at density and pressure,
this unit is basically an extension of the last two units.

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 your lab
information. There are two parts to the worksheet. You will attach your
worksheet to question #1 in the question section.

A Look Ahead
Earlier
in this course we learned about energy, specifically mechanical energy. In the
upcoming units we will be discussing other forms of energy such as light, sound
and electrical energy. It is important to learn how these different forms of
energy move and transfer. They move as a wave. So in the next unit we will be
exploring different types of waves, how they move and how to use them to
calculate frequency, period and wave speed.
Below are additional educational resources and activities for this unit.
