Some of our Valentines STEM challenge cards have a post that goes along with it and can guide you in setting up and materials. I will list all of the Valentines Day STEM challenges below and link to the proper posts or provide you with helpful materials!

What do Valentines Day STEM challenges look like?

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. Check out the graphic below and go here to get your copy.

How to set your kids up for Valentines STEM challenges

Mostly, you have the opportunity to use what you 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.

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

You can definitely 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.

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

If you check out our winter tinkering basket, 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.

Check out our main science activities page for all our holiday theme collections. There’s something for everyone.

Start with these ideas and build from there. We will have new challenges for each new season and holiday. Print out your Valentine’s Day STEM challenge activity cards.
