As I wrote about last month, I’m really working hard to improve STEM in my classroom. I’ve created posters to teach the engineering design principles that students need to learn (download for free in my TPT store!), and we are working to incorporate them every chance I get. Valentine’s Day seemed like a perfect opportunity.
Before we go too far, I have to admit that the cookies had nothing to do with the STEM activity. It has been my tradition for 25 years to bake heart cookies for my students on Valentine’s Day, and I really liked the alliteration of cookies and catapults. So, full disclosure, this blog post will focus on catapults!
The question we decided to answer was “Which would fly farther, a Hershey’s Kiss or a candy heart?” The students worked in partners to build the catapults, then we grabbed our measuring tapes and went outside to collect data. Each pair was responsible for collecting data for three trials for each type of candy. They collected their data on a data collection sheet, and then we went back inside to put our data together and find an average. You can download the Valentine’s Day Catapult data sheet for free below the pictures! They had to do some great math because they converted centimeters to meters, and then added and divided to find the average.
The students put their data together on a class data collection sheet, and then they had an answer to their question! Most importantly, they had a blast while practicing some key math and science content in a real-world experience. And they ate candy! What’s not to love?
Thank you to Sonya DeHart for designing the border I used on the Data Collection Sheet and to A Primary Kind of Life for creating the font on the Data Collection Sheet. Check out these talented teachers!
