  • Put seven tablespoons of each liquid in a cup and leave it out overnight.
  • Fill up each square with the different liquids in the cups.
  • Put it in the freezer and set the timer for 15 minutes.
  • Stick a toothpick in it every time the timer goes off
  • See which one takes the longest to freeze

The results could have been affected by me opening the freezer every 15 minutes. In the future, I will check it every 45 minutes. It would be interesting to see that if the freezer was at a lower temperature if the results change.]]> 2018-06-11 13:14:21 UTC https://padlet.com/ec55105/csq8e4vymcux/wish/266607450 Purpose ec55105 https://padlet.com/ec55105/csq8e4vymcux/wish/266607452 To determine the liquid that takes the longest to freeze.]]> 2018-06-11 13:14:21 UTC https://padlet.com/ec55105/csq8e4vymcux/wish/266607452 ec55105 https://padlet.com/ec55105/csq8e4vymcux/wish/266612141 2018-06-11 13:33:20 UTC https://padlet.com/ec55105/csq8e4vymcux/wish/266612141 Picture of frozen lemonade. ec55105 https://padlet.com/ec55105/csq8e4vymcux/wish/266934561 2018-06-13 02:34:23 UTC https://padlet.com/ec55105/csq8e4vymcux/wish/266934561 Picture of frozen water. ec55105 https://padlet.com/ec55105/csq8e4vymcux/wish/266934790 2018-06-13 02:36:16 UTC https://padlet.com/ec55105/csq8e4vymcux/wish/266934790 Picture of frozen Gatorade. ec55105 https://padlet.com/ec55105/csq8e4vymcux/wish/266935006 2018-06-13 02:37:55 UTC https://padlet.com/ec55105/csq8e4vymcux/wish/266935006 Picture of frozen Coke. ec55105 https://padlet.com/ec55105/csq8e4vymcux/wish/266935370 2018-06-13 02:40:59 UTC https://padlet.com/ec55105/csq8e4vymcux/wish/266935370 Picture of slushy syrup. ec55105 https://padlet.com/ec55105/csq8e4vymcux/wish/266935488 2018-06-13 02:42:01 UTC https://padlet.com/ec55105/csq8e4vymcux/wish/266935488
