10 Best Science Kits For Kids to Learn STEM Skills

So you've heard that kids love science kits and decided to get one for your kid? Excellent!

We'll tell you what they are, what makes them so popular, and then give you a list of ten best science kits to spark your child's curiosity. Let's dive in!

What is a science kit?

First things first, you can't choose quality science kits unless you know they are, right?

Well, think of a science kit as your kid's own science lab where they explore different scientific concepts and conduct their own experiments in an extremely engaging and fun way.

With gadgets like a magnifying glass, test tubes, safety glasses, and other real science tools commonly included in kits, little scientists get to dive into a world of discovery. These kits turn complex scientific principles into exciting, hands-on activities.

And it's not just about observing chemical reactions!

Many science kits focus on other areas like engineering, electricity, robotics, and even environmental science. They offer a range of experiences, from building simple machines to designing electrical circuits.

The variety of options ensures that you find science kits that align with your kid's interests, helping them grow and learn—and that's the topic we'll cover next.

Why are science experiments and kits beneficial for kids?

They say that repetition is the mother of learning. We'd like to add active participation to that, because when kids get hands-on with science experiments and activities, the learning experience becomes much more powerful and memorable.

Need a piece of evidence?

Sure, we've got you. Or, the University of Chicago has.

According to a UChicago study, learning by doing "helps students perform better in science". Alright, but how exactly?

Well, the study found that students who took a hands-on approach to learning had activation in sensory and motor-related parts of the brain when they later thought about concepts such as angular momentum and torque.

This finding tells us that it's better to allow kids to directly experience the concepts they're learning about, rather than just reading about them.

And since you can't really fling your kid into space to learn about gravity and planetary motion, science kits are the next best thing.

Besides brain activation, hands-on experiments help kids develop their critical thinking and problem-solving skills, as they learn to hypothesize, experiment, and independently evaluate results.

All in all, when you combine active participation with the natural curiosity of children, you get a powerful mixture that transforms learning into a brain-boosting adventure. Sprinkle some kits into the mix, and you have the perfect recipe for sparking a lifelong passion for science and exploration.

Fun, hands-on way to acquire STEM skills

By now, we've established that there are tangible benefits to science kits for kids.

Unfortunately, just because something is good for kids, it doesn't mean they like it. Broccoli, bedtime, and brushing teeth are just some of the examples.

The great news is that, unlike the reluctant acceptance of broccoli and bedtime routines, science kits fall into the category of educational activities that kids actually enjoy and look forward to.

In fact, kids are really into this hands-on learning style. Research shows that an impressive 73% of students would prefer their science classes to be taught only through experiments, which shows us their enthusiasm for active and engaging educational experiences.

So, what are you waiting for? Educators love them, kids love them, and now you will, too.

Let's find the most engaging ways to introduce science to your little one.
