Description:

Candy Box STEM Challenge: A Fun and Engaging Valentine’s Day Science Activity Looking for a creative way to celebrate Valentine’s Day while boosting your students' critical thinking and STEM skills? 

The Candy Box STEM Challenge is a hands-on Valentine’s Day science activity that’s perfect for grades 2–8. Students will design, build, and test their own containers to fit candies or cupcakes, all while tackling engineering problems in a fun, festive setting.

What’s the Candy Container Challenge All About?

Students work individually or in small groups to design the “heaviest” heart possible using a criteria and constraints list. 

They will:  

  • Create smaller hearts of different sizes and colors, with assigned point values.
  • Arrange them inside a larger outer heart to achieve the highest possible “weight” (measured by points, not actual weight).
  • Experiment with configurations while applying math concepts like addition, measurement, symmetry, ratios, multiplying & dividing decimals, and percentages—customizable for younger and older students.

What’s Included?

NGSS-Aligned: Tailored for grades 2-8 with adaptations for varying skill levels.

Editable Student Handouts: Design analysis templates, data recording sheets, and discussion questions.

Teacher Support: Step-by-step guidance, materials list, and helpful STEM video series.
