Experimenting in 4B and 4E

We have been experimenting with different materials to see what would take less tome to melt ice.  We had to write a procedure of what we would do in our experiment. We first thought of a hypothesis to predict what we thought would happen when we mixed different materials with ice. We had to think about the materials we would use and the steps we needed to follow in order to be successful with our experiment.  While we were experimenting with the materials, we recorded the elapsed time to think about how long the ice took to melt, so could see which material would melt the ice the fastest. While our ice was melting we monitored the chemical reactions that were occurring. We looked at the results of our experiments and used this to reflect on our hypothesis so we could write a conclusion.

We noticed:

  • The bicarb soda took a very long time to melt the ice. The bigger part of ice stayed solid and the smaller parts started to turn white as it mixed with the bicarb.
  • In conclusion the bicarb soda did not melt the ice in 40 seconds, instead it took 25 minutes and 9 seconds to melt.
  • In conclusion the lemon juice and ice took a very long time to melt ice and salt was the quickest to melt the ice.
