Once the newness of school wears off, kids and teachers alike start to feel the drudgery of the day-to-day grind of school. Where at first school was all new clothes and freshly sharpened pencils, now, it’s just early mornings and homework.
One of my favorite ways to keep school fresh throughout the year is to throw in hands-on activities related to the current season. These salt crystal leaves are the perfect fall science experiment, and cleverly mimic the appearance of frost on a fall leaf. Combine colors and shapes of fall with science in this clever fall STEAM activity by making salt crystal leaves.

These Salt Crystal Leaves Will Make You a Science Wizard
I love how these leaves become crusted with sparkly, perfect salt crystals. It’s such a pretty way to learn about ionic bonds!
What you’ll need to make salt crystal leaves:

- Fill your jars with water (we put 2 leaves in each jar) and fill a saucepan with that water. Boil the water on high heat.
- While the water is boiling, poke a hole in the center of each leaf and thread a pipe cleaner through to make a long leaf stem.
- Suspend the leaves from a plastic fork placed over the mouth of the jar.
- Once the water boils, add enough salt to create a sheet of salt crystals across the surface of the water. Turn off the heat.
- Pour the water into the jars, covering the leaves.
- Wait three days to one week for the crystals to form.
- Remove the crystals from the water and dry on a paper towel.
- When the crystals are dry, examine them with a magnifying glass to learn about salt, ionic bonds, and how crystals form.
Salt Crystal Science
Salt crystals form when a solution of water becomes over-saturated with salt. As the water evaporates, the salt crystals cling to one another, forming large squares of salt, just like are found in nature. Kids will be fascinated by the ionic bonds that salt makes, creating perfect squares and rectangles every time.
