On Valentine’s Day, most parents of schoolchildren are frantically searching the stores for classroom valentines. I’m a bit of a sucker for any sort of pun, but since we love STEM so much in this house, we are particular fans of all of these Valentines STEM activities.
But if you’ve forgotten to pick up a set, hate the idea of spending money on something kids are just going to throw away as soon as they get home, or want a more creative class Valentine theme, then you’ll love these Chemistry valentines for kids.

Best of all, these chemistry valentines are kid-friendly. Some of the Valentine chemistry puns I came across and thought of when making these valentines for kids weren’t really child or school appropriate.
It’s probably not just me, but I always think it’s a little weird when kid valentines are mushy. Kid valentines should promote friendship, especially when you have to give one to every kid in the class!
Imagine telling 20 people they are your soulmate.

Now, here’s the secret to printing in color.
Most home printers (unless they are photo printers) don’t do great when printing whole color pages.

So, if you want a professional look, use a photo printer or take your PDF file to a print shop.
But, if you don’t want to do that, if you use a glossier paper, the colors should come out better.
Alternatively to that, use cardstock for stability and color clarity.

How to Use Your Printable Chemistry Valentines
You’ll use the button in this post to grab your free chemistry valentines. Then you can save the file to your computer and print at your leisure.

Once the valentines are printed (I definitely recommend printing on cardstock paper), cut them out and let your child write their name on the back of the valentine.
If you’re feeling extra ambitious, go ahead and tape a piece of candy or a small toy to the valentines.
Drop them in your child’s backpack and you’re done!

Definitely easier than a trip to the store fighting all the other last-minute Valentine shoppers (save that for your significant other).
