Lately this has become a very common theme.

Kids are bored. They really want something to do. Something interesting, exciting and fun!

Parents are trying to find ways to entertain and educate their children.

Homeschooling has become incredibly popular, but parents are struggling to find cool science experiments to do at home. Something that is suitable without breaking the bank when it comes to supplies, won’t destroy their home, and that will actually teach their kids about chemistry, biology and physics.

So with that in mind, here are the top 20 Science Experiments to do at home as chosen by not only me, but the readers here at STEAM Powered Family!

The Best At Home Science Experiments

In selecting which experiments ranked as the absolute BEST science experiments to do with your kids at home we had a few different criteria.

  1. They needed to be popular! These experiments are tried and true, and have loyal following of readers that LOVE doing them. Once you try them, you will know why STEAM Powered Family readers voted these as their favourite science experiments!
  2. Supplies must be relatively easy to source. In most cases you will likely have all the materials you need at home right now. Where you need to order or purchase a few supplies, they are readily accessible and links to purchase are included.
  3. They must be easy to do, with logical, easy follow directions. We are all overwhelmed. No one wants an experiment that is complex and confusing.
  4. The experiments need to be adaptable to wide variety of ages, grades, abilities and interests.
  5. The lessons need to be interesting! In all of our science experiments and STEM activities, we include a scientific explanation that either your children can read themselves, or you can read and use to help explain the experiment.
  6. They need to be FUN!

With that in mind, here are our top 20 picks for the BEST science experiments to do at home with your kids!

Baking Soda and Vinegar Experiments

There are so many cool experiments you can do with these pantry staples. Yes, you can do a standard volcano, but you can also hatch dino eggs, create fireworks, set off explosive bottle rockets and more! You can keep your kids busy experimenting for a ages with all of our baking soda and vinegar ideas. Get your hands on some bulk vinegar and baking soda and get experimenting!

Oobleck

Oobleck is like slime, but much more fascinating and sciencey! Oobleck is a non-Newtonian Fluid that becomes solid under pressure, and liquifies when pressure is removed. It is fascinating, and we have a number of different recipes, so you can find the one that uses whatever you have available in the house.

Make a Compass

This science experiment is really cool and a wonderful tie into geography and social studies lessons. Kids learn how to make a compass with materials from around the house.

Make a Lava Lamp

With 5 different ways to make a Lava Lamp, it’s no wonder our readers rate this as one of their favourite activities! Kids are fascinated by the chemical reaction that causes the mesmerizing bubbles to bob up and down in a science driven lava lamp experiment.

Grow Crystals

This is one of the most beautiful experiments we have done and always gets rave reviews from readers. Growing crystals is a wonderful science experiment that has fantastic ties to studies in geology. You can also grow edible crystals. Plus the results… STUNNING!

Rubber Egg

Ready for a fun, giggle-fest science experiment? In this science experiment we are removing the shell of a raw egg! The result is a bouncy, colourful egg. This science experiment is the perfect compliment to a study of biology and reproduction as you can also use this experiment to teach the parts of the cell and egg.

Lemon Battery

You could make a battery with lemons, squash, pumpkins, potatoes, there are lots of options! But the lemons are by far the most popular battery project. You will need some supplies, but once you have those supplies you can reuse them in lots of circuit building activities. Plus, once you are finished making your lemon battery, you can make lemon volcanoes!

Wingardium Leviosar

Whether you are a fan of Harry Potter or not, this experiment with magnets is a hit with kids. It’s like magic as they make a feather levitate!

Walking Rainbow

This classic experiment is a beautiful demonstration of primary and secondary colours, while also learning about the fascinating science behind capillary action. All you need to start your rainbow walking is cups/jars, water, food colouring and paper towels!

The Walking Rainbow science experiment should have been easy, but due to a mistake we discovered a fascinating capillary action and natural balance project.

Make Bioplastics

Making bioplastics is an experiment that is a HUGE hit with older kids as part of their studies in polymers and environmental sciences. We have made bioplastics with both milk and gelatin, so you can pick which one to tackle based on the supplies you have on hand. Wonderful for helping kids understand how we can make plastics, and the challenges of making plastics, without fossil fuels.

Build a Heart Model

This engineering project is a fantastic way to do some studies into biology and how the heart functions. Using recycled bottles, straws, a bit of playdough and water, you can have your model pumping in no time!

This Heart STEM activity to build a functioning heart model uses all 4 STEM pillars - Science, Technology, Engineering and Math. Kids will spend some time learning about their own heart rates, then how blood flows through the body. For the exciting conclusion engineer and build a functioning model of a beating heart.

Skittles Experiment

A simple, yet timeless experiment. Kids of all ages love making these gorgeous images using nothing but candy, water and the magic of science. We also used this as a chance to explore van Gogh and fluid dynamics.

Magic Milk

So easy, yet so amazing! Magic Milk is another classic experiment that is as simple or as complex as you want to make it. I did this with my middle school kids and we had a blast exploring how the fat content of our milk affected the explosion of colours!

Slurpee Science

Heat transfer is a fascinating science to explore with your kids. If you want to make this a more serious scientific study, you can focus on the effects of salt on ice, but we like to up the fun, so we turned it into a slurpee making science project. Kids love that delicious treat made with science!

Sweet slurpee science is a fantastic activity for kids, with a tasty result they will love. This simple heat transfer experiment is perfect for all ages.

Elephant Toothpaste

Elephant Toothpaste classic experiment creating a fantastic foamy fountain that can be done safely at home using easy to source supplies and has massive wow factor for students.
