Engineering STEM Projects

Along with free online games, you may be surprised to learn that free STEM education games can be found or created from the objects in your home or kitchen pantry. These budget-saving STEM projects, like the “marshmallow challenges” (where you have students construct solid structures applying marshmallows and toothpicks), are a fun way to introduce basic concepts of engineering and creative and critical thinking. Even Legos from the toy bin can create a foundation for or introduction to understanding engineering. These STEM challenges could inspire your students to try or pursue their own real-world applications someday.

Marshmallow Challenges: See steps for several different STEM projects with images
Balloon Car Activity: Make your own balloon-powered car, then challenge your friends to make their own and have a race!
Paper Airplane Designs: Different paper airplane designs fly in different ways. Try out a few to see which ones fly the farthest, stay in the air the longest, or even do interesting stunts when you throw them.
Egg Drop Project: Can you build something that will protect a raw egg if you drop it on the ground?
