Valentine’s Day is upon us and I personally feel that a science-themed valentine always gets a “reaction!”
For the classroom, check out this FREE demo on Secret Messages, because let’s face it, who doesn’t like get a secret message on Valentine’s Day. This simple demo uses phenolphthalein and a bleach solution to reveal secret messages that disappear again when dry so you can use them again and again for other classes.
Passing out Valentine’s? Check out these two ideas my girls and I made for their classroom Valentine’s Day party.
“Beary” Good Chemistry
A test tube full of gummi bears to let your friends know that you think your friendship has “beary” good chemistry? Yes, please.
I used plastic test tubes with screw caps I found on Amazon Rainbow-B 20 Clear Plastic Test Tubes with Caps, 25x140mm(40ml) with 1 100ml Plastic Beaker and filled them with Haribo Gold-Bears Gummi Candy, 5-Pound Bag. 5 pounds is a little excessive, but necessary if you’re like me and eat a handful for every test tube you fill.
Finish off this “beary” cute valentine with some decorative string used to tie on the cards that you can download for FREE here.
Brighten My Day
Grab a value pack of neon bracelets or necklaces such as the 8″ LumiStick Brand Glowsticks Glow Stick Bracelets Mixed Colors (Tube of 100).
Print out the Valentine Card FREE template by Nitty Gritty Science. Cut out each tag and paste on colored cardstock. Use a hole punch to make a hole at each heart on the end of the template. Slide the neon bracelet through each hole. Don’t forget to add the piece that allows the neon stick to become a bracelet.

Flinn Scientific joins in on the holiday fun and offers this FREE download of Chemistry Puns for Valentines along with a demo called The Vanishing Valentine. This demo starts off with a blue solution which turns clear, then turns pink after shaking as a result of an oxidation-reduction of resazurin.
