Brief Guide to Kids Science Kits

Studying science is great for kids but nothing can replace hands-on experiments when learning biology, chemistry, physics, and other sciences. Children retain more and enjoy actively doing rather than studying from books.

These kits are designed to encourage learning through fun. They offer a range of engaging and educational experiments for different age levels, from the youngest scientists to younger teens. Even adults admit to enjoying these kits, so be warned you may want to buy a variety of types.

What Are They?

A kids science kit has everything you need to conduct hands on, interesting, scientific experiments at home with your children. The kits will have the ideas of what to do, instructions, and the equipment you need, plus give you guidance as to what age range they are suitable for.

Nowadays science kits range from the more traditional chemistry set to robotics projects, physics, human body, electronics, volcano making, maths and even ice-cream science. Some are also gender specific, so that girls can find ideas for things to make that will interest them in particular.

Who Can Benefit

If one of your children loves science, then get them one of these kits to encourage their interest and take it further. But for any children, whether they are already interested or not, this is a great investment, so long as you or someone in your family can put aside a bit of time to help them with it.

In a science kit there are so many possibilities and potential activities, that it will very quickly get children engaged and asking questions. It also fosters creativity, and an understanding of how things work.

Kids will benefit from these kits in a multitude of ways, for example by learning how to follow step by step instructions, how to predict what might happen, and how to think logically through different possibilities. They will also need to be careful with some of the equipment, so should learn in the process how be safe around chemicals and equipment.

It is also generally thought of as important that children should be attracted to science while they are young. It is while they are young that they learn through hands on activities, and ask a lot of questions, and early interests are known to influence what they are interested in as they get older.

If you homeschool your kids, this could also be a great option to enhance your science lessons. Often homeschooling curriculum will give you ideas for science experiments but they won’t give you the equipment to do it, so you have to hunt around and shop for what’s necessary.

This means that you often don’t get around to doing any hands on science. With these kits you can just get them out and read the instructions and everything should be contained in them and be a lot easier.

What To Look For?

Learning should be fun and interesting – so look for kits that have ideas that will appeal to your child, and have explanation and pictures to go with it. You could look for an idea that they are already curious about and use it to help them learn even more about the subject.

Orville Wright, one of the Wright brothers who invented the aeroplane, was quoted as saying, “the greatest thing in our favor was growing up in a family where there was always much encouragement to intellectual curiosity.” (July 24th 2017)

Look for an age range on the kit – because of the safety issues with chemicals and other hazards it is important that you find a kit that is age appropriate for your child, and that you supervise them while they use it.

What To Avoid?

Avoid buying a second hand very old chemistry set, because they used to contain dangerous materials that we wouldn’t consider safe these days like uranium dust and sodium cyanide. Also look for a type of kit that you are comfortable with – for example, if you don’t like chemistry you might not want to get a chemistry set for your child as you will most likely have to help him with it!

Also look for how much room is needed and if there are loud explosions or messes made, and just make sure that you are happy with what is going to be involved in doing the activities.

Have a look on the packaging or description to make sure that nothing else is needed besides what is in the kit. If there are other items needed then you might want to purchase these ahead of time so your scientist doesn’t get frustrated.


Which science kit would be best for my child?

Try and find out what they are interested in – is it volcanoes, space, explosions, electronics, plants, etc.? Then have a look and see if you can find a kit that matches their interest and also their age range. Kids that like gadgets will probably like kits that are based on technology such as robotics and electronics.

Kids that like bugs and animals can find experiments that work with those, and biology might be the way to go. If they are interested in things that fizz and foam, then they would probably like a chemistry kit.

Are science kits dangerous?

Nowadays most science kits will probably contain household items, and not much of any danger because of regulations. However you should still read the instructions, be aware of any hazards or cautions there, and supervise you children when using them.

What is the big deal about STEM?

There is a lot in the news and articles nowadays about STEM – science, technology, engineering and math. What’s the big deal, and why should we get out kids interested in it?

Well, the reason is that in our future there is going to be a big need for people to work in these areas, and we don’t have enough young people studying in these fields to provide what we need. So those fields will make for good job security, and also hopefully be relatively well paying since there will be a lot of demand and not that much supply.

They are also creative and innovative fields – a lot of new things like sending astronauts to Mars, and discovering new molecules are in STEM fields, so they represent the cutting edge of our future. If we get our children interested in them while they are young, there is a greater likelihood of them pursuing it when they are older.

Wrapping Up

Crafting a messy volcano and or seeing a successful experiment will foster a lifelong love of science in young minds. Work towards helping kids explore safely and spark critical thinking early. Science seems to hold an almost never-ending fascination for children. One way to capitalize on this early learning interest is to provide opportunities for them to experiment.

Kits vary a good deal according to their intended age range. Basic kits for younger children might contain only a few materials and will rely on parents to come up with a number of common household ingredients and tools like measuring cups and baking soda. While more complicated kits for older children will be packed with more materials and experiment ideas.

Buy any of our reviewed and top kits with confidence.  Most kids science kits are reasonable priced and pack hours of exploratory play.  Start making memories today with any one of these kits.  Thy also makes a great gift for children who have an active curiosity or may not get exposure early to STEM-related skills and comprehension.
