how to put water in the freezer and make it not freeze

for week 2 of school we had to find out how much salt to put into water to make it not freeze.
  1. What do we need to find out? THE AMOUNT OF SALT THAT MUST BE IN WATER BEFORE
  2. IT WILL NOT FREEZE WHEN LEFT OVERNIGHT IN THE FREEZER.
  3. How will we find it out? What i think is that we put different samples in the freezer and find
  4. out the next day
  5. How will we record what we find? Well we can put a table in our drive and have sample 1 in
  6. one box and so on.
  7. What equipment do we need for the experiment? Cups,salt,freezer and water.
  8. How long will it take? One night.
Step 1: put half a cup of water in a cup.
Step 2: put different amounts in the cups.
Step 3: name them for example test 1 and so on.
Step 4: wait overnight and have a look to see which one is good is still water the one that is water
is the right amount.

  1. Nice job on your water and salt experiment write up, Ashton. Please make sure your sentences aren't running off the page.

    Make sure you complete step 3, the diagram, and post this to your blog!
