Easy science experiments for young children

Science is exciting, fascinating and loads of fun for all the family. You don’t need to have a chemistry degree or a laboratory to get your little ones having fun with science. Here are some easy experiments you can do at home.



Create a tornado in a bottle

You will need;

  1. Two plastic bottles
  2. A tube to connect the two plastic bottles
  3. Water


Whirl the liquid in the top bottle and it creates a vortex as it drains down into the bottom bottle. This happens because as the water flows down, air must flow up, which creates a tornado effect. You can make it even more fun by adding some food dye or glitter to the water.

Make your own lava lamp

You will need;

  1. Water
  2. Oil
  3. Food colouring
  4. Effervescence tablet (supervised)


Oil and water have different densities and polarities, so when you mix them the water sinks to the bottom. Add food colouring (which is also water-based) and this will sink to the bottom too. Crumble in an Alka-seltzer and it’ll react with the water, causing droplets of coloured water to rise to the top, pop, release air and then sink back to the bottom.

Water fireworks

You will need;

  1. Two glasses or Bottles of the same size
  2. Food colouring of your choice
  3. Oil
  4. Water
  5. Fork
  6. Tablespoon


Fill one glass almost to the top with room temperature water, pour two tablespoons of oil into the other glass, along with two drops of food colouring. Stir the oil and food colouring with a fork until the food colouring has broken into smaller drops. Now pour the oil and colouring mixture into the other glass. As the food colouring slowly sinks, each droplet will expand outward to create an amazing firework effect!
