    Because of that, you can start with minimalistic projects that still get kids thinking, such as this paper bridge design challenge.

    What equipment do you need?

    You only need the following:

    • Paper
    • Coins
    • Ruler
    • Tape
    • Books or small boxes

    How is this useful to kids?

    Who knew you could get into civil engineering with so few materials?

    Jokes aside, the simple paper-bridge project can teach kids about load distribution, tension, and structural integrity in a practical manner.

    It lets kids experiment with different designs and see firsthand how various factors affect the strength and stability of their bridges. Hard hats are optional!

    And that's all!

    How is this useful to kids?

    If you want a uniform chain, you'll need to measure pieces of paper carefully, introducing young ones to basic concepts of measurement and precision.

    They also get to explore how different paper widths impact the strength and length of their chains. This is an excellent opportunity to show the children that math is absolutely everywhere around us.

    Additionally, the fact that the activity is so simple also means that you can upgrade it however you like.

    For instance, you can challenge your kids to make the longest paper chain possible with just one sheet of paper. Doing so will make them think of different ways to cut, fold, and link the strips to maximize the length of the chain.

    Idea #5: Do a coding challenge

    Let's not forget what the T stands for in STEM! To nudge your kid in the direction of technology, you can suggest playing around with programming. The simplest way to do this is with block code, which introduces little ones to the basics of coding without complex syntax.

    If you're looking for a specific suggestion, we recommend Scratch, a visual programming language.

    Brace yourself; here's a monstrously long list of hard-to-procure supplies you need for this project:

    • Paper

    On a serious note, you really only need paper to build planes. You can add an artistic flair to your creations with stickers, but bear in mind that these will add some weight and make the plane crash sooner.

    How is this useful to kids?

    Playing with different plane shapes and sizes introduces kids to fundamental principles of aerodynamics. Testing different plane variations will also teach them about lift, thrust, weight, and drag—the essential principles of flight.

    How to prep younger kids for these no-prep STEM activities?

    As promised, you don't have to run to a crafts store for any of these STEM activities for kids; you already have all the materials. However, there are steps that you can take to prepare your child for a meaningful learning experience.

    1. Choose those STEM activities that match your child's age and skill level.
    2. Set up a distraction-free environment for experimenting. It helps if you and your child are off the phone, too.
    3. Explain the goals in simple terms. For instance, you can say: "We are going to make a paper airplane that can fly far. We will use different shapes and folds to make it aerodynamic, which means it can move smoothly through the air."
    4. Praise effort. Completing a task, even a simple one, can be a big deal for a young child.

    Following these steps will help ensure a positive experience that shows that STEM is fun, exciting, and rewarding.

    Of course, participating in activities together can also help you strengthen the relationship you have with your little ones.
