Three Science Experiments for Kids

The science experiments we remember from school are probably the most dramatic ones! The explosive, messy ones that left the biggest path of destruction! When it comes to science and experiments, many parents think it’s best left to the classroom. The thing is, science can be so fun and engaging even from a very young age. If you’re interested in getting your children involved in science from the beginning, this is the article for you.

Lava Lamp Experiment

Exciting Science Experiment for Kids

The lava lamp experiment is always a hit with kids. It’s visually very appealing and it’s also really fun for all involved and simple too.

Here’s what you will need, only a few items:

To begin you need to colour about half a cup of water with a vibrant coloured food colouring. In a separate glass fill it roughly with ¾ of vegetable oil. Add the coloured water to the glass, leaving a few inches from the top. Then break up each Alka tablet into 2 or 3 pieces and let your children add bits to the glass. This experiment works because the water and oil are unable to mix. The oil, therefore, won’t change colour because the food colouring is only water soluble. The Alka tablets react on contact with the water and create tiny bubbles of carbon dioxide.

The Raw Egg Experiment

The Dad lab is a great resource for science experiments and this is where we spotted this next experimental idea. This experiment looks at gravity and motion with a simple set-up and quick process if you’re stuck for time.

Here’s what you will need:

  • 3 glasses of water
  • 3 raw eggs
  • 3 toilet roll tubes
  • A piece of cardboard

Things could get a little messy with this one if you’re not careful. Perhaps start your kids off with one egg first!

Cola Mentos Experiment

This is a trick most kids learn somewhere along the road! Adding mentos to a cola bottle and watching it erupt. It’s a dramatic experiment and that’s why all kids seem to love this one.

The mentos cause all the carbon dioxide bubbles to rise to the surface at once. Mentos have lots of small craters on the outside and when dropped into the bottle, bubbles form on the surface of the mentos which causes the gas to be released.

Here’s what you will need:

  • An unopened bottle of diet cola
  • A pack of mentos
  • A protective sheet

We definitely recommend doing this experiment outside if you can! There is a lot of mess and we all know how sticky cola can get. We spotted this experiment on, where you can find plenty of other great science-based activities.

There are so many ways to incorporate a scientific theme in to crafts, activities and games. Why not set yourself a challenge and aim to explore one science experiment every week. Even once a month would be a great way to spend some quality time doing something fun at home. A rainy day event or a way to fill the weekends when money is tight.
