Looking for some Valentine’s Day activities that your students will love but are more than just a craft or activity to pass the time? Valentine’s STEM Challenges (or STEAM Challenges) engage your students in brain-busting work disguised as fun!

From this hub page, you will find everything you need to know about all five Valentine’s Day STEM challenges: links to resources, blog posts, video walk-throughs, and teacher feedback on each resource.

Valentine’s Day STEM Challenge Basics:

Students work in partners or groups against criteria & constraints lists to design and build Valentine’s-themed items using science, technology, engineering, and math skills to complete the tasks and extensions. Modification suggestions are included to make these challenges engaging and productive for students in grades 2 – 8.

Working against a criteria/constraints list in groups, students will design and build a bow & arrow set for Cupid’s Valentine’s Day target practice. (Designing the quiver is optional.)

– Option: if you find bow & arrow design too difficult, modify the challenge to make throwing darts instead.

– Students will aim for high scores as they take three shots each at a Valentine’s themed target. Final scores are taken as the sum or average of their personal and/or team results.

As with all my challenges, modifications are included to make it appropriate for grades 2-8.  More details can be found in resource, blog, and video linked below the teacher feedback.

Teacher Feedback on Cupid's Quiver

The “M” in this STEM challenge should be an extra-large capital letter, because it is definitely the focus in this 2-D challenge!

Working against a criteria/constraints list individually or with partners, students will design the “heaviest” heart possible.

– Using a criteria/constraints list, students create small hearts of various colors & sizes. Point values are assigned to each color group based on its size. Students arrange various configurations of their smaller hearts inside a large, outer heart in order to create the “heaviest” possible heart. (“Heaviest” is in quotation marks because we are not measuring weight; rather, we are assigning point values to inner hearts.)

This challenge can be run simply (focusing on shape creation & manipulation, measurement, addition, and symmetry), or you can add complexity (focusing on length/width ratios, multiplying & dividing decimals, percent contribution, etc.). Two criteria/constraints lists are provided to highlight either end of the spectrum along with editable versions.

As with all my challenges, modifications are included to make it appropriate for grades 2-8.  More details can be found in resource, blog, and video linked below the teacher feedback.

Teacher Feedback on Heavy Hearts

Working against a criteria/constraints list individually or in partners/groups, students will design and build the tallest “tower of love” possible using Valentine’s Day cards they were probably just going to throw away anyway! (Note: for older students or those who don’t exchange cards, an alternative love-notes handout is included.)

As with all my challenges, modifications are included to make it appropriate for grades 2-8.  More details can be found in resource, blog, and video linked below the teacher feedback.

Teacher Feedback on Cards in the Clouds

Working against a criteria/constraints list individually or in partners/groups, students will design and build the smallest container possible to house a candy assortment.

– “Confection Container” alternative: students will design and build the smallest container possible to house one or more cupcakes (keeping frosting on the cupcakes, not the box!)

– Because this can be treated as two separate challenges, two criteria/constraints lists have been provided: one for candy and another for confection (cupcake).

As with all my challenges, modifications are included to make it appropriate for grades 2-8.  More details can be found in resource, blog, and video linked below the teacher feedback.

Teacher Feedback on Candy/Confection Container

Individually or in partners/groups, students will design and build a uniquely talented bouquet of flowers! This STEM challenge actually contains four challenge prompts that can be taken separately or simultaneously in groups:

– Floating Flowers

– Fluff & Flatten Flowers

– Functional Flowers

– Firmly Fixed Flowers

I will never apologize for my love of alliterative titles. ☺

Note: Although it is part of the Valentine’s Day bundle, this challenge works well for spring, Easter, and Mother’s Day as well.

As with all my challenges, modifications are included to make it appropriate for grades 2-8.  More details can be found in resource, blog, and video linked below the teacher feedback.
