Science, Math, and Philosophy Lessons for Valentine’s Day

Valentine’s Day is just a couple of days away. If you teach primary grades, your students may be excited about exchanging little cards and candies (my daughters have been talking about it for weeks). If you teach middle school or high school students, you’re probably bracing yourself for a few days filled with extra teenage drama. Either way, you may be interested in the following Valentine’s Day-themed science, math, and philosophy lessons.  

Late last week SciShow Kids released a compilation video featuring five Valentine’s Day-themed lessons and projects. Creating edible glass hearts is my favorite one in the compilation video.

Creating edible glass hearts is the topic of a fun SciShow Kids video. The video begins by explaining how glass is made before moving into an explanation of how sugar, like sand, can be melted. The video then explains why isomalt is used to make edible glass hearts (melting point) and how it can be done at home with the supervision of a parent. Like all SciShow Kids videos the description includes lots of links to additional resources including this one that has written directions

If you’re looking to work a little Valentine’s Day themed activity into your middle school or high school classes in the next couple of days, here are three good videos to consider viewing.

Why Do We Love? is a TED-Ed lesson that explores some philosophies on why people love. The lesson won’t provide you with any clear answers, but it will make you think. And isn’t that what philosophers want you to do?

The following video from It’s Okay To Be Smart (produced by PBS Digital Studios) explains why humans kiss, the history of symbols associated with kissing, and some cultural views of kissing. When I saw this video I immediately thought of my friends who teach middle school and high school health classes.

The following fun video, also from It’s Okay to Smart, attempts to use math to determine the odds of a 25 year old woman finding love in New York. (Remember, the video is just for fun).

And if you’re looking for a last-minute card-making activity, try having kids create animated Valentine’s Day cards in Canva.  Canva offers free templates for creating greeting cards for all occasions including Valentine’s Day. Many of those templates can be quickly turned into animated GIFs with just one click. In this short video I demonstrate how to create an animated Valentine’s Day card by using Canva’s free greeting card templates.
