10 Fun Science Experiments to do While Inside

Struggling to find activities to do while inside? Why not dig through the cupboards and find all those household items that can double as a fun experiment as well. Not only will it keep the kids entertained, but it will stimulate their brains and trick them into learning something more!

  1. The Volcano – I’m sure you’ve seen it before, but have you ever tried it at home? All that’s needed is a bottle, or generous supply, of Coke and a few Mentos (depending on how much mess you’re willing to make). Pop the Mentos in the bottle and stand back to watch the explosion unfold.
  2. Mouldy Bread – Now it might sound gross and something that you would prefer out of the house, but it’s a great way to watch how mould appears. Grab a few slices of bread and place each one in a different location. One could be on the front veranda, another on the kitchen bench and even one in the fridge. Monitor the slices each day to see how long it takes for those little green spots to appear.
  3. Make your own putty – This one is a non-stick activity, meaning no worries about the clean-up. All that’s needed for this one is a bit of corn-starch and some soap (Making sure to leave enough to wash those hands).
  4. Singing Bottles – Using a few different bottles, fill each bottle with a different level of water. Place in a line and blow along the top to hear the different sound each one makes. Who knows, you might even be able to start a new band!
  5. Elephant Toothpaste – I’m sure your students have seen it before, but now it’s a chance for them to show you a thing or two. Combine soap, yeast and hydrogen peroxide to watch the magic happen. Just a tip, make sure it’s away from computers or anything that could be harmed and be very careful handling hydrogen peroxide.
  6. Rube Goldberg Machine – Unsure what it is? It’s those videos of the dominoes falling and the ball rolling down to the pipe which then connects to a conveying toy which then does this and so on. Now it’s your chance to assemble the dominoes and marbles and books and balls to create your own series of moving pieces!
  7. Paper Aeroplanes – While it might sound simple, the structures and different types of aeroplanes that can be made are endless. Choose a few different types and then set a distance. Which one will go the furthest? Which one flies for the longest?
  8. Egg Drop – Grab out an old shoebox, some bubble wrap and any piece of material students might think will cushion the drop of an egg. Place the egg in a box with each material one at a time and see if the egg survives the drop.
  9. Coloured Water – Using food colours, place drops into a glass of water. Looking at each colour that comes out with different combinations of colours and number of drops can help demonstrate the difference between primary and secondary colours.
  10. Spaghetti & Marshmallow Tower – Using uncooked spaghetti and the marshmallow colour of your choosing (I prefer the white ones), assemble a tower or bridge or industrial building. Whatever it may be, make sure it can stand on its own!
