How to Grow Crystals of Salt

Crystals of Salt

The crystal making would be an exciting project for the children as they could keep a collection of them for viewing.

Things needed

  • Toothpicks (2 Nos)
  • Scissors (1)
  • Jar (1)
  • Water
  • Spoon (used to stir)
  • String
  • Salt (half a cup)

How to Make

  1. Pour water into the jar until it is full.
  2. Add salt(half a cup) to the jar containing water.
  3. Stir the saline solution with the spoon.
  4. Using the scissors, cut the string and tie it to the two toothpicks at both ends.
  5. Keep the string at the jar top with the toothpick ends at the edges.

What happens next

Let the solution to settle for a while so that salt crystals form along the strings . These crystals are an ideal of how cubic crystals would look like and students could do more research on them using microscopes.

When we have a closer look at them, we could spot the differences between them like are there microbes present in them; what shape they have; what color it has and are they formed properly.

The crystals formed could be put in various lots like small crystals and large single crystals. There would be a large variation in their size as some would be thin like wafer or even microscopic level whereas some would be tall enough with height of meters.

Try making a collection of crystals of different shapes, sizes and label them accordingly and keep them in a box for viewing your work afterward.
