Every fall, trees change color as they lose their leaves before winter. In some places, these leaves can make forests look
like they’re catching on fire!

But why do leaves turn red, orange, and yellow every fall?

Most trees’ leaves can’t live in the cold. When fall comes, the leaves start to die and fall to the ground.

Follow these steps and you’ll get to see all the colors of a leaf at once! Just make sure you ask an adult to help you.

What You Need

• 3-4 glass jars, one for each leaf

• 1 large spoon

• Rubbing alcohol

• White coffee filters

• Plastic wrap

• Scissors

• 3-4 leaves (Find as many colors as you can, but green works too!)


  1. Rip up a leaf and put the pieces in one of the glass jars. Use the large spoon to crush the leaf until its juices leak out. Pour rubbing alcohol into the jar until the leaf is covered.
  2. Cover the jar in plastic wrap and place it in the fridge. You’ll need to leave it in the fridge overnight.
  3. Repeat steps 1 and 2 for the rest of the leaves.
  4. The next day, get your jars from the fridge and throw away the plastic wrap. Cut the coffee filters into long strips with your scissors. You’ll need one for each jar.
  5. Place one end of the coffee filter into the jar so that it just touches the leaf juice. Wait for 30 minutes to an hour.
  6. Pull the coffee filter out of the jar and let it dry. The coffee filter will show you the range of colors in the leaf!
