👉 Watch the video of Sarah’s school science experiment here!
Hello parents, teachers and students! Here’s a fun experiment that Sherlock Holmes would be proud of, exploring the science of chemical reactions!
Be sure to check out GMSA@9 on Wednesdays when Meteorologist Sarah Spivey does the demonstrations and explains the science behind it.
HERE’S WHAT YOU’LL NEED
Grape juice concentrate (like the stuff in the freezer isle!)
DO THE EXPERIMENT
In a cup, mix some water and baking soda. There should be enough baking soda in the water solution so that it looks cloudy
Using a Q-tip dipped into the baking soda and water solution, draw or write something onto the index card. Allow it to dry
Paint the grape juice concentrate onto the index card and watch as your drawing magically comes into view. It should look like this ⬇️
HOW IT WORKS
Baking soda is a base while the grape juice is an acid. Whenever an acid and a base combine, some sort of chemical reaction occurs. In this case, the baking soda and water solution turns a darker color, becoming visible!
SCIENCE WITH SARAH
If you’d like Sarah and David to come to your school and conduct a science experiment live on KSAT, email email@example.com.
Parents and guardians: upload a video of your child performing the activity by clicking here. Send it in and you might see it on GMSA @ 9 a.m.!
