What Are Rainbow STEM Challenges?

STEM challenges are usually open-ended suggestions to solve a problem or challenge that are meant to get your kids thinking about and using the design process.

What’s the design process? I’m glad you asked! In many ways, it’s a series of steps an engineer, inventor, or scientist would go through when trying to solve a problem.

What Supplies Do You Need?

Mostly, you have the opportunity to use what you already have and let your kids get creative with simple materials.

My pro-tip is to grab a large, clean, and clear plastic tote or bin. Every time you come across a cool item you would normally toss into recycling, toss it in the bin instead. This goes the same for packaging materials and items you may otherwise throw away.

To add to your holiday or seasonal theme STEM challenges, hit the craft or dollar stores for inexpensive theme items to add to the mix. For rainbows, choose bright colors!

Standard STEM materials to save include:

  • paper towel tubes
  • toilet roll tubes
  • plastic bottles
  • tin cans (clean, smooth edges)
  • old CDs
  • cereal boxes, oatmeal containers
  • bubble wrap
  • packing peanuts

Also, make sure to have:

  • colored craft tape
  • glue and tape
  • scissors
  • markers and pencils
  • paper
  • rulers and measuring tape
  • recycled goods bin
  • non-recycled goods bin
  • pipe cleaners
  • craft sticks (popsicle sticks)
  • play dough
  • toothpicks
  • pompoms
