Science experiment for school.

This month the verse we have been studying is Matthew 5:13b ...But if the salt have lost his savour, wherewith shall it be salted? it is thenceforth good for nothing, but to be cast out, and to be trodden under foot of men. The major concept is: Inefectiveness brings harsh consequences. We have been learning about the many characteristics of salt, and how it applies to our responsibility as Christians to positively affect the world around us for good. One of the things they have been learning is that there are serious consequences for being ingrown Christians. This is illustrated by the Dead Sea. The dead sea receives water but never gives any back. The salt, which is useful in so many situations has killed almost all forms of life in the Dead Sea.

One project the kids did was to see how much salt it would take to make 3 cups of water dense enough to make an egg float. The egg was almost floating at 8 teaspoons, and at 10 teaspoons, it popped right up. They found that it takes approximately 1.1 tablespoons per cup of water to make the water have the same properties as the Dead Sea.

Lets remember to be "salty" christians!

  1. Hello! What a wonderful lesson. I'll store that idea away and do it with my boys someday. :)
