Kitah Gimmel has shown so much curiosity and interest in the topic of the Dead Sea. It started with the sensory experience they were invited to partake in last week (more info on that here) and continued with Circle Time discussions.
Capitalizing on that interest, today we did a science experiment inspired by the salt crystal formations surrounding the Dead Sea.
Before we began the experiment, the children were shown two examples of salt crystals: One was the type that grow organically at the Dead Sea, and the other was a picture of crystals grown on a string similar to what we were going to do. Showing the pictures was intended to aid in making the connection between their classroom learning and the experiment, as well as highlight the differences between a natural salt crystal, and those we are attempting to grow.

"I like eating salt with challah!"
"Nothing can live in the Dead Sea!"
"Only people can go in the Dead Sea."
For the experiment, we followed some simple instructions of mixing salt and water in a jar, and suspending a string in it by a pencil. Our new vocabulary word was, "dissolve."
The children were eager to volunteer for both pouring and mixing duties, and eventually we had 3 jars on a sunny spot on the window sill, waiting for crystals to form. It should take 1-3 weeks to start seeing some results. Here are some pictures of the process:
