Best Science Kit for Kids: Reviews and Buying Guide

best science kit for kids

A science kit is a great way to get kids interested in science and to make their imaginations soar! If your child is showing an interest in science and is looking to start doing experiments, then the gift of a science kit might just be the perfect thing for them.

But which one do you choose? We compiled a list of the 10 best science kits for both young and older kids that is sure to spark interest as well as educate them on the wonderful world of science!

But before we look at the list, here are some things to know about STEM, what to look for when shopping for a science kit as well as some tips to make experimenting a happy, fun experience.

All the kits featured on this list are safe but note that some are more suitable for older children.  We made sure to provide a mix of kits so that there is a science kit for everyone.



What is STEM?

STEM stands for Science, Technology, Engineering, and Math.  While STEM activities are part of the school curriculum, having your child engage in STEM activities out of school can not only set them up for success in school but also open doors to other interests (and maybe even a future as an engineer, scientist or something else!)

STEM teaches kids more than just science and math.  It can help kids become better problem solvers, get them to become more curious, help promote a positive attitude, introduce them to new and exciting concepts and much more.

STEM for Infants and Toddlers

You’ll probably be surprised that many of the activities your infant or toddler already does are considered a STEM activity!  Having your child explore the world around them is a perfect introduction to STEM. No tools required!

Learning through play is crucial to young children and how they make sense of their environment. A great STEM activity for infants and toddlers is simply to provide them with different (safe) objects for them to hold and yes, even taste like crinkling paper or feeling smooth and textured balls.

STEM for Preschoolers

Once your child reaches preschool they are ready to start experimenting! Now that doesn’t mean they should be mixing chemicals together, but providing them some basic science tools is a great introduction into STEM.

Some of the kits on this list are suitable for children as young as 3 and will include everything your budding scientist needs.  Let kids fill test tubes with water or other safe liquid or study plants, bugs, and other things with a magnifying glass.

Participating with your child and asking them probing questions is another way to get their brains thinking about science.  Here are some ideas for experiments that you and your little scientist can do!

  • Mixing oil and water
  • Growing a seed
  • “Engineer” a building out of things around the house
  • Make a volcano out of baking soda and vinegar
  • Go for a “shape hunt” in your neighborhood

Science for School-Aged Children

Once your child is a little older the fun can really begin. Many of the kits on this list are geared toward school-aged children.  By the time they are in kindergarten and first grade they’ll be able to follow simple instructions for more fun and exciting activities.

Some activities that can be made in the kits below include:

  • Making slime and goo
  • Learning about fossils and dinosaurs
  • Making wiggly worms
  • Making a model of the earth and its layers
  • Growing crystals

Those are just a few of the many activities that children can do.  But just like infants, toddlers and preschoolers, encourage your child to explore and learn through curiosity and exploring their environment.

What’s in a kid’s science kit?

STEM toys are a great way to get kids curious about math and science, especially a science kit. But what should you look for in a science kit for your kid?

Some things a science kit should include are:

  • Test tubes (and test tube stand)
  • Magnifying glass or microscope
  • Tweezers
  • Measuring spoons or cups
  • Pipette or eye dropper
  • Scale
  • Funnels
  • Instructional guide
  • Goggles

But what about chemicals? Many of the kits do provide safe chemicals such as food coloring, citric acid, cornstarch and others.  However, for most of the science kits, you’ll also need to go into your own kitchen pantry to find what you need to help your kids experimenting! Things like baking soda and vinegar are commonly used supplies that your little scientist will need to start experimenting.

Which science kit do I choose?

The determining factor on which one to choose is of course which one you think your child will be interested in! Does your child like dinosaurs? There are sets that include rocks, fossils, and “prehistoric” experiments. Does your child like getting dirty or things that go “boom”? Many kids’ chemistry will have everything you need to make a bottle rocket or an oozing slimy concoction.

But what if your child has no clear interest in science? Perhaps they just need an introduction to science to see what interests them. The first two kits on our list are great first science kits for kids. They have a good variety of experiments to choose and may spark interest in exploring another science topic, be it chemistry, biology or something else.

Tips, Safety, and Precautions

Science kits for kids do not contain anything that would be considered dangerous. However, many do suggest a child be a certain age or that there is an adult supervising while the kids handle the tools and ingredients.

Here are some things to keep in mind when kids are using a science kit:

Wear old clothes and have towels on hand.  Again, many of the products used in the experiment are not harmful, but some include things that ooze or contain coloring which can stain clothes.  Also, having towels on hand will help in case you need to catch the overflow of an enthusiastic volcano or toppled test tube.

Have a child wear goggles and/or gloves. For experiments that go boom, fuzz, splash or froth, wearing goggles or gloves will not only help for safety reasons but also get your kid in the mindset of a real scientist.

Set up outside.  Depending on the weather, you may want to take it outdoors. It makes clean up a lot easier and can lead to other scientific discoveries like bugs, plants and more.

Think outside the box.  While all the kits on this list come with instructions on how to do experiments, allow kids to use their imagination and do their own experiments.  Experiments can be done by using safe household items like lemons, baking soda, food coloring and such.

Let your kids take the lead.  It might be tempting to step in and do the experiment for them, but resist the urge. Science can be messy and that’s okay.  (For kids, that’s also half the fun!) Allowing your child to explore is the best way for them to learn, even if that means a bit of a mess.

Top 10 Science Kits for Kids

So now that we’ve taken a look at what you should look for, let’s see which science kits made the cut! The great thing about them is they won’t cost you an arm and a leg.  These affordable fun kits are designed specifically for kids.  Many of them do require additional supplies, but luckily, you most likely have them at home already (i.e., baking soda, vinegar, lemons, etc).

Frequently Asked Questions

Q: How old does my child have to be in order to have a science kit?

A: There are science kits out there for kids as young as 3! Many of the more advanced kits that include experiments start around 6 years old.  However, the science kits for kids even younger than that are a great way to introduce young ones to science and get them exploring.

Most experiments involving chemicals and more advanced skills start around age 6. Many of the kits on our list suggest adult supervision.

Q: Do I really need to buy my child a science kit in order to do experiments?

A:  A science kit is not a requirement in order to start having your kids do science experiments. However, science kits are an affordable and convenient way to fuel your kid’s interest in science. Most sets come complete with everything you need to get started, but also come with instructions and other learning tools and complete the scientific experience.

Q: Are science kits safe for young kids?

A:  Yes! All the science kits on this list have safe chemicals and tools.  But be sure to check the age on the kit.  While they are all very safe for kids, some are more suitable for older kids (8 and up) because they feature things that ooze, fizz, explode or require skills that younger children may not have developed yet.
