science fair 2017


Science fair

My science fair question is How fast does ice melt with different things added to it? I want to find this out how to make ice last longer. I have a Waikato science fair booklet. I have started recording in my science log book. I have been learning about the hypothesis and have been making estimations. I did some background research and then made another guess. I have listed some ideas I am going to try including...
-salt
-sand
-soil
-saw dust
-styrofoam 
-sugar   



 Here are my guesses from before my research

Fast
Slow
Salt
Sugar
Sand
Soil
Styrofoam
Saw dust 


Here are my guesses from after my research

slow
Not at all
Salt
Sugar
Sand
Sawdust
