1. The document describes a student's experiment to demonstrate how icebergs float using a model made of chicken wire, newspaper, flour, water, aluminum foil, and spray paint. 2. The student learns that icebergs float due to several factors: water is less dense as a liquid than as ice, icebergs contain air bubbles, and icebergs are made of fresh water which is less dense than salt water. 3. When mold grew on the student's iceberg model while drying, they learned mold grows quickly under warm, moist conditions.

5. 1. Get the sheet of chicken wire and shape it so it looks like an iceberg. 2. Mix one part flour and two parts of water until you get a smooth glue then dip newspaper strips in the glue and coat the chicken wire with it. 3. Make little balls of aluminum foil and stick it on one side of the iceberg while the glue is still wet. 4. Wait until it dries rock hard. 5. Spray paint the iceberg white. 6. Cut the lid off the shoebox 7. stick the background on the floor of the box and cover the sides in blue paper. Make a platform out of cardboard and stick it in the box with a hot glue gun. Cover the platform with paper as well. 8. Rest the model on the platform.

6. My iceberg Looks good and fits In the shoebox well. I have learnt that icebergs float because of many reasons. One is that water is slightly denser as a liquid than as a solid, this is why ice cubes float in water. Icebergs also contain billions of tiny air bubbles which is represented by the aluminum foil balls on my iceberg. Lastly icebergs are made from fresh water, because of the dissolved salts in ocean water, it is denser than freshwater, adding bouyancy to the icebergs. Also when my iceberg was in the drying stage I forgot about it until the last minute and I found that mould was growing on it. Mould grows quickly in warm, dark and moist conditions. My model was moist for a long time I should of added salt in the glue to prevent mould.

Denser: 1. tightly packed: so close together that there is little sense of open or unoccupied space a dense jungle a dense population of 2 million 2. very thick: so thick that it is difficult or impossible to see through dense summer haze BIBLIOGARAPHY: http://encarta.msn.com/encnet/features/dictionary/DictionaryResults.aspx?search=denser , www.flamingtext.com , http://www.kidzone.ws/science/mold.htm , http://familycrafts.about.com/cs/papermache/a/blpmpastes.htm , http://www.animationfactory.com , www.
