50 Simple STEM Activities using 15 Materials


I started doing simple STEM activities with my children at home, and students at school, a few years ago. They all loved it! They were always excited when I brought in materials and gave them a chance to create, problem solve and use their imagination. Because of the learning and engagement I saw every time we did one of this projects, STEM activities have become a regular part of my teaching program.

One of the great things about STEM activities is that they don’t have to be expensive. As a teacher I wanted to find a collection of STEM activities and challenges that didn’t require expensive materials or a lot of prep.

I created this collection of 50 Simple STEM Activities using only 15 materials. Most of the materials are supplies you likely already have on hand, such as paper, elastics and scissors.

STEM activities are a great way to develop Science, Technology, Engineering and Math skills. The more of these skills mixed into the activity, the better.

The collection of 50 STEM activities featured below are all hands-on building challenges. They each use, one or several of the 15 materials needed to do all of the challenges.

If you teach a STEM program, or simply want to bring more STEM to your child’s learning, this program is the perfect place to start. Print the activity cards, fill a bin with the 15 materials and you’re ready to go!

Simple STEM Activities Materials

There are 15 materials you will need in order to do the STEM challenges. The more of each material you can collect, the better. All of the 50 STEM activities in this program use some combination of the materials below. It may look like a lot of supplies, but keep in mind that it is for 50 different activities! You will need:

  • Wooden blocks
  • Construction paper
  • Clothes pins
  • Plastic cups
  • Plastic building blocks
  • Tape
  • Scissors
  • Ping pong ball
  • Large craft sticks (tongue depressors)
  • Playdough
  • Paper rolls
  • Elastics
  • Balloons
  • Aluminum foil
  • Straws

Once materials are used for a STEM challenge, hang onto any left over supplies and any other supplies that can be reused for your next STEM challenge. Many of the challenges allow the materials to be recycled and used again and again.

I’ve included an example below of a STEM bin I created in the past full of materials that I pulled from for each STEM challenge.

Once you have all of your materials collected, print the activity cards for the challenges.

Benefits of Simple STEM Activities

STEM activities are a great, and fun way to encourage essential skills. These challenges promote critical thinking, creativity, team work, and problem solving. Children learn that the process is as important, if not more important than the final result.

A key part of STEM challenges is trial and error. Encourage children to create and test their solution. If it doesn’t work, have them think about what does work, and what doesn’t and recreate based on what they have learned.

If there is an activity in this collection that you think is going to be too challenging for your group of children, you can always alter the activity, or add more supplies, to make the activity easier. However, avoid helping children as soon as they run into problem. Part of the learning comes when children get stuck. Give them the chance to learn from their mistakes.

STEM Activity Printables

There are 50 activity cards included in the product for the STEM challenges. They are included in the resource in different formats. Print the format that works best for you.

Included in the printables, there is also information about STEM education, a student planning sheet, certificates for children upon completing STEM challenge(s) and a list of all of the activities.

Whether you use the activities to keep kids busy on rainy days or plan a weekly STEM challenge virtually all year round, this resource is easy to set up and, with the exception of collecting materials, there is no extra prep work involved.

There are lots of different ways you can set up your STEM program. You can print the cover page with the activity cards to create individual packages for children to work through at their own pace, as one option.

Since I have been doing STEM activities in my classroom for several years, I have found that they make great centers!

Grab a collection of clear bins, print an activity card and attach the card to the top. Inside the bin, include the materials children need for the challenge.

For older children, you can print the smaller activity cards and attach them all with a ring. I laminated my set so that I can use them for many years. Children can choose an activity, and grab the supplies needed and begin creating.

Another way to use the activity cards is to print them and put them in a bag along with the supplies needed for the challenge. These make great kits, or gifts, to give to children to create with at home.
