1. Scientific Experiment
How buoyant are icebergs?

2. Hypothesis:
I think 10% of the iceberg will float and 90% will sink.

3. Materials: A balloon A plastic bag A rubber band A large bowl
Ice cubes
A ruler
A calculater
Materials:

4. Procedure:
Fill the balloon with water until it is about the size of a grapefruit. Tie off the end of the balloon and place it in the freezer. Repeat steps 1 and 2 using the plastic bag, except this time, seal the top using the rubber band. Be careful not to overfill the bag. Wait for 12 to 24 hours to fully freeze your ice bergs. Fill the bowl, bucket or fish tank with cool water. Add the tray of ice-cubes and stir until they have melted. Take your icebergs from the freezer and remove the balloon or bag. Place the icebergs on the sink and measure the height of each one. Procedure continued

5. Procedure continued
Place the icebergs in the bowl, bucket or fish tank and measure how much of your iceberg is floating above water.

6. Where to find your Materials
You can find the balloon and plastic bag at the DollarTree.
