Buoyancy And Density Activity
Name ________________________________________ Date ____________________________ http://phet.colorado.edu/en/contributions/view/3350 Buoyancy and Density Activity

Directions: Go to the following website to use an interactive simulation to work with buoyancy and density.

Procedure:
Getting Familiar
1. On the Intro screen, mess with the apparatus, changing the blocks, observing what happens when the mass, volume and densities are held constant.
2. Check and uncheck the boxes under “Show Forces” to see where they act.
Intro: Give a brief description of what the relationship is between mass, volume and density of each object and how it affects whether the object will sink or float.

Lab Setup
1. Click over to the Buoyancy Playground and begin the lab.
2. There are 5 different fluids to choose from in the lab and five different types of materials. (Styrofoam, wood, ice, brick and aluminum)
3. Use the table supplied to organize your work.
Lab Procedure: Part 1
1. In each of the scenarios below, determine first, by predicting, whether the object will sink or float. Use a mass of 4.5 kg.
2. Test each object once you have predicted and record the results.

Part 1: Write an “S” for sink or an “F” for float. Predictions first!!

Air
Gasoline
Olive Oil
Water
Honey

Lab Procedure: Part 2
1. For each of the objects, determine the density at which it sinks in kg/L.
2. Use a mass of 4.5 kg.
3. List this value in the table.

Lab Procedure: Part 3
1. In this part of the lab, determine the amount of buoyant force that is acting on each block of mass 4.5 kg.
2. Determine how you will find the amount of buoyant force or “buoyancy.” Perhaps try using the two scales given in

If you put an egg in tap water, it will sink to the bottom. If you add enough salt, the egg will float to the surface. Density is the mass or volume of an object. It’s easier to think of it as the thickness of the object. Buoyancy is the force that allows an object to float. I performed a fun experiment to see how increasing density of water could make an egg float or submerge. Anyone can do it.…

The purpose of this experiment is to compare the different densities of different liquids. Density is a comparison between an object's mass and volume. Density = Mass divided by Volume. If the weight (or mass) of something increases but the volume stays the same, the density has to go up. If the mass decreases but the volume stays the same, the density has to go down. This experiment will show how the weight of certain liquids react to each other.…

My project is about how much salt it will take for objects to float. In my project I will explain why certain objects float while others sink. I took three different objects with different amount of density and put them each in ten cups of water. I then put in teaspoons of water and recorded whether or not the objects floated until all the objects were floating. I was able to see how an objects density affects how much salt is needed to make it float.…
