Joshuas fann science power point

  1. 1. JOSHUA FANN’S POWER POINTlAND ICE / SEA ICE EXPERIMENT:Aim:To see if the ice would melt and would it change the air temperature.Hypothesis:I think the air temperature might change.Research: We researched in the science room with a group measuring three differentbeakers with sea water and ice cubes. Also we needed to use a thermometer in eachbeaker to measure the temperature change every minute for 10 minutes.Equipment: Three Beakers, One liter of Sea Water supplied by Joshua Fann, ThreeThermometers, Six Ice Cubes, Tin Foil to cover Beakers and also to make a substituteland model. We also needed an accurate watch to keep taking new results every minute.Method:1. Set up three beakers all the same size.2. Pour in 200 ml sea water into each beaker.3. Put in model tin foil land.4. Place ice cubes on top of land. One ice cube in the first beaker, Two ice cubes in the second beaker and Three ice cubes into the third beaker.5. Cover each beaker with tin foil6. Puncher hole for the thermometer to go through.7. Start timer.8. Take a temperature result every minute.9. Do this for 10 minutes.! ! ! ! ! ! ! ! ! ! ! ! Page 1.

But looking at our results the beaker thatcontained two ice cubes actually had the coldest air temperature. The three ice cubebeaker had the coldest water temperature.Application:This experiment has shown that if the Polar Ice Caps continue to melt the water and air willcontinue to be cold. This is not a suitable habitat for humans.Bibliography: Prabyjot, Joshua, Piper, Tai Ming and Mrs H.! ! ! ! ! ! ! ! ! ! ! Page 2.
