engineering-projects-for-kids

Do your kids like engineering and science? We’re not surprised: its super cool to make stuff that actually “does stuff!” Here are 35 fun DIY engineering projects just for kids that you and your family will enjoy. Notice that some are perfect for tiny tots and other projects are terrific for older kids and teens. Use your best judgement and provide adult supervision and guidance when needed.

One of the great things about doing these DIY projects is that kids actually learn how things work – from gravity, physics and other science concepts. It’s not just about creating the DIY – but making it do something – and you can launch the rocket or sail the boat again and again. So it is something that your child can learn engineering concepts from, as well as DIY skills too.

We do have a few suggestions for you. If you are launching a rocket or making the paper airplane launcher for example, always explain to your children that these are “outdoor DIY experiments only.” Otherwise you will have rocket launching in the living room and a concern about your windows, family photo frames or mirrors for example. As you do these DIY projects, encourage your children to develop some practical skills to put into place while using them.

Notice what science concepts your child is learning in school and which STEM DIY and engineering projects you can do in the home so they can really have fun learning about it. There is a huge difference between reading a dull textbook and making a marble maze or building a cool paddle boat! Happy DIYing!
