The Math and Science of Valentine's Day

Valentine's Day is less than two weeks away. In middle schools and high schools everywhere there will be students who are excited about it, some who dread it, and others who are indifferent. I always fell into the indifferent category. Wherever your students stand on Valentine's Day, the following two videos make for interesting lessons about Valentine's Day.

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).

How Sea Turtles Find Their Way Home

A few years ago I had the privilege to witness sea turtles nesting in Costa Rica. Since then I have been fascinated by how they are able to find their way back to their birthplaces years later. So when It's Okay To Be Smart published a video about sea turtles, I stopped what I was doing and watched it immediately.

In How Baby Turtles Find Their Way Home Joe Hanson, Ph.D. explains how sea turtles find their way home in a manner similar to that of salmon. Viewers also learn how the turtles' initial struggle to reach the ocean helps them return home years later. In the second half of the video we learn how Kemp's Ridley sea turtles were saved from extinction.


Your students can learn more about sea turtles in the free Disneynature Explore app.

Smells Like Rain - A Science Lesson

Last week Why Are There Clouds? was one of the most popular posts on the Free Tech for Teachers Facebook page. A good follow-up to that lesson is found in Where Does the Smell of Rain Come From? Produced by It's Okay to Be Smart, Where Does the Smell of Rain Come From? explains why we sometimes think we smell rain before a thunderstorm. Through the video we also learn about the role of petrichor in the lives of some animals.


It's Okay to Be Smart includes a list of references with each video. Open the description below the video on YouTube to find links to the references.

Applications for Education
At this time of year in the northern hemisphere we start to have more thunderstorms and large rain storms. This lesson is one that students can share with friends and family when they say, "it smells like rain."
