Can You Grow Salt Crystals On Leaves?
Can you grow salt crystals on leaves? Looking for the perfect fall stem activity that helps showcase science? We have a great new challenge for you.
What you need per person...
- Can You Grow Salt Crystals On Leaves? Creator Sheet
- Sticks for each leaf
What you need to do...
- Students will begin by picking groups and/or working independently. Pass out the Creator Sheet to each student or group.
- Have all items passed out at tables
- Tell students that the objective of this experiment is to see how salt can turn into crystals on leaves.
- Students fill all of their cups with water - and the pour into the pot
- Bring the pot of water to a boil (with adult supervision)
- Make sure you have your leaves gathered
- Take the string and cut a few 8-12 inches long pieces - one piece for each leaf you have
- Take the string and tie it to the middle of the stick
- Tie the leaf’s stem to the other end of the string
- Then you will lay the stick on the cup, so that it is balancing and the leaf is hanging freely
- After water boils - add in half a cup of salt and make sure the salt dissolves
- Continue adding salt until you see a film on the surface of the water
- Remove from heat and turn off the stove
- You will then pour the hot salt water into the cups and completely cover the leaf
- Let the leafs sit in the cups overnight - and crystals should start to form
- Set a timer to see how long it takes for the crystals to form
