Volume - Amount of space a 3-D object takes up. ( b x h x w = volume )
Mass - The amount of weight something has
Density - mass per unit volume
( Density = mass/volume)

• What do you think will happen to a gummy bear soaked in water for 24 hours?

• Write you educated guess in this part of the lab.

• Gummy Bear
• Triple Beam Balance
• Metric Ruler
• Calculator
• Cups
• Water
• Data table

1. Gather Materials and label cup with group name.
2. Measure and record data required by your data table.
3. Calculate volume of day one length x width x height
Round to the nearest hundredth in cm cubed

4. Measure mass in grams using balance.
5. Calculate Density by dividing the mass by the volume. (We will discuss in class)
6. Put 100ml of water into beaker and put bear in beaker.
7. Day 2 Remove bear and place on paper towel.

8. Repeat all measurements from day one.
9. Calculate and record the changes.

Volume
Mass
Density
Day 1 Day 2 Change

• Write down what you noticed before we take the bear out of the water on Friday.

• Must answer all of these question
1. Was your hypothesis correct or not?
Why?
2. Which change was greater, volume or mass?
3. Was there a change in density?
4. What is density? How did this lab help you understand density.
