Saltwater-Freshwater Experiment

How is seawater different from what comes out of your tap at home? The saltwater of the sea actually has different properties. Try this "Saltwater-Freshwater" experiment to learn what a pinch of salt can do!

What You'll Need:

  • Sea water
  • Bottled tap water
  • Two mixing bowls
  • Bar of pure soap
  • Potato peeler
  • Teaspoon
  • Eggbeater
  • Dish detergent

Next time you're at the seaside, try this experiment to compare salt water to fresh water:

Step 1: Pour two cups of sea water in one bowl and two cups of tap water in another bowl. Use a potato peeler to shave soap flakes from a bar of pure soap.

Step 2: Put a teaspoon of flakes in each bowl. Beat with an eggbeater. Which makes better soapsuds, fresh water or salt water?

Step 3: Clean the bowls and do the same experiment with dish detergent. Is there a difference between the kinds of suds produced?
