Have fun growing your own salt crystals with this simple project. You can do more research with a microscope, once finished. The crystals are beautiful to look at and might even want to start your own collection.
What you'll need:
What you'll need:
- A jar
- Water
- About half a cup of salt
- A spoon for stirring
- String
- Scissors
- 2 toothpicks
Instructions:
- Fill the jar with water.
- Add about half a cup of salt to the water.
- Mix the solution together with a spoon.
- Cut a piece of string with scissors and tie each end to a toothpick.
- Place the string over the top of the jar so that the string dangles into the middle of the solution and the toothpicks hang over the edge.
- Don’t forget to clean up when you’ve finished.
Abandon the experiment and wait for the salt crystals to form along the chain. They are an excellent example of cubic crystals and can do more research by examining them under a microscope.
When you look at the different crystals under the microscope can examine the differences between them: They are perfectly formed? What shape? What color? Can you see all microorganisms in the crystals?
The crystals can be found grouped in a lot of small crystals or large crystals. They vary in size from those at the microscopic level everything up to the crystals that are meters long!
Try to collect a number of crystals for your project, the label of the different types and make a rock collection box to keep in
