Hello parents, teachers and students! If you’re looking for fun way to explore how fossils are made, check out these gummy worm and bread fossils!

Be sure to check out GMSA@9 on Wednesdays when Meteorologist Sarah Spivey does the demonstrations and explains the science behind it.

Science with Sarah: Invite KSAT to your school for live science experiments. (KSAT)

HERE’S WHAT YOU’LL NEED

Here are the materials you’ll need to make your own bread fossils (Copyright KSAT 2022 – All rights reserved)

4 slices of bread
Gummy candy
Plastic wrap
Heavy books

STEP 4: Place heavy books on top of the “sandwich.” You can either wait for 24 hours or press down on the books.
STEP 5: Unwrap your “sandwich” and remove the layers of bread and gummy candies. Notice how the gummy candies leave imprints in the bread.

HOW IT WORKS

This experiment shows how pressure over time can create fossils.

The books represent the pressure on soil and rock over millions of years.
The imprints left by the gummy candies represent fossils!
