What do Valentines Day STEM challenges look like?

STEM challenges are usually open-ended suggestions to solve a problem or challenge 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 to solve a problem. Learn more about the steps of the engineering design process.

How to set your kids up for Valentines STEM challenges

Mostly, you can use what you have and let your kids get creative with simple materials.

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

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

Make sure you have:

  • tape
  • glue and tape
  • scissors
  • markers and pencils
  • paper
  • rulers and measuring tape
  • recycled goods bin
  • non-recycled goods bin

Plus, you can make up an inexpensive Valentine’s Day tinkering kit with seasonal items!

Also, read about STEM on a budget for more ideas.

If you check out our Valentine’s tinkering tray, you will find a great list of supplies that are pretty common and easy to pull together. I love making themed tinker kits. Young kids really get a kick out of novelty activities and put a little excitement back into everyday projects.
