Looking for a fun Christmas or winter activity that incorporates science, technology, engineering, and/or math? Winter STEM / STEAM Challenges are the perfect activities because they engage your students in brain-busting work disguised as fun!

The basic premise:

Working against a criteria/constraints list in partners or groups, students will design and build a “snowball” fortress wall with two main criteria: greatest area (or just height or length for younger students) and ability to withstand a “snowball” attack.

Note: This is the digital format, compatible with Google Slides ™.

Sample/suggested materials for each student or group:

(Materials you’ll need to do the activity are easily modified. You don’t need to provide all of the following materials. Select a subset and/or add in your own ideas.)

For each student or group:

• Marshmallows: large, mini, or a mix (35 – 50)
  • Sugar cubes or blocks can be substituted for building the fortress wall, but at least one marshmallow per student will still be needed for a “snowball” attack.
• Straws (10 – 15)
• Popsicle/craft sticks (10 – 15)
• Toothpicks (25 – 50)
• Small paper plates (1 or ½ of one)
• Ruler
• Scissors
• Work mat (construction paper, foil, newspaper, etc.)

Optional:

• Plastic knives, forks, and/or spoons
• Pipe cleaners
• String
• Foil
• Spool of wire (gardening or steel)
• Tape
