KENTUCKY 6/14/17 — From keeping drinks cold to creating a camp fire, summer can offer a lot of challenges. 

INGREDIENTS

  • Salt
  • Cooler
  • Ice
  • Water
  • Digital Thermometer


INSTRUCTIONS

STEP 1:  Fill the cooler half of the way with ice and cold water. Describe the ice water by using its observable properties. Using the digital thermometer, make measurements to identify the ice water based on its properties.    
STEP 2:  Add one cup of salt to the ice water, mix, and observe. Describe the ice water by using its observable properties. Using the digital thermometer, make measurements to identify the ice water based on its properties. Did the water get colder after the salt was added?     

EXPLANATION

Once the salt is added, the temperature of the ice water drops. The salt lowers the freezing point of water. Basically, salt allows water to exist at a liquid below 32°F or 0°C.
