STEM challenges allow students to work cooperatively and are great for team building and are just plain FUN! This Valentine Card Zip Line Delivery STEM Challenge is a fun and engaging activity to celebrate Valentine's Day while practicing the Engineering Design Process.

This challenge requires simple materials that you probably already have on hand. You’ll need index cards, straws, tape, string, paper clips, a small paper cup, and a Valentine card.

In my classroom, it is a team competition. Students work in teams of 3 or 4 and I assign team roles (Materials, Build Director, Time Keeper, and Recorder) by numbering off my students (all 1’s are the recorder, all 2’s are the timekeeper, etc.). The Valentine Delivery Challenge objective is to design a system that will carry a card to the end of the zip line. Each team works together to design, build, test the design and revise and record their ideas, designs, and modifications and complete the pages of the STEM Challenge Journal as they go through the challenge.

What's Included?

❤️ Teacher directions

❤️ STEM Challenge slides to print or project to follow the steps of the Engineering Design Process

❤️ 8 page STEM Challenge Journal booklet for your students

❤️ 20 point Rubric

This Challenge follows the Engineering Design Process cycle of Ask, Imagine, Plan, Create, and Improve. It also includes a reflection activity or discussion at the end of the challenge.
