  • Travelling coloured water experiment

    Travelling coloured water experiment

    Very easy experiment to learn about basic colours and water properties. Fill some glasses half way or less with water and add food colouring. Place an empty glass in between each colour and create a bridge using fabric or paper towels. Hypothesis/Question: Will the water travel to the empty glasses? Will we get new colours?…

  • Glitter water surface tension experiment

    Glitter water surface tension experiment

    Very short and easy experiment to explain surface tension to kids. Pour water on a plate, sprinkle glitter on top, dip finger in dish soap and watch the glitter floating away from the finger. Why: water molecules cling toghether and they arrange themselves to create a force/energy called surface tension. Glitter does not mix with…

  • Candy DNA

    Candy DNA

    Make a DNA model out of candy and toothpicks. Warning: kids might eat more than their daily ratio. Explain what DNA and teach them about its structure and sequencing.

  • Water cycle in a bag

    Water cycle in a bag

    Another activity from Sophie’s homework. Easy way to learn the cycle of water and its stages by putting some water in a sealed bag close to a source of heat (sun/radiator). Learn about evaporation, condensation and precipitation using this small microclimate.

  • Lighting a bulb with static electricity

    Lighting a bulb with static electricity

    Static electricity can provide enough power to light up a fluorescent light bulb for a short time. All you need for this is a balloon, a woolly scarf and a fluorescent light bulb. Go to a dark room, rub the scarf against the balloon, hold the light bulb from the bottom and bring it close…

  • Snow vulcano

    Snow vulcano

    This volcano was requested again, this time in the snow. Yet again I only had red dye so the final result looked like a massacre. All you need for this is baking soda, vinegar and some colour. I used powder pigment for this.

  • Green & shiny pennies

    Green & shiny pennies

    Here’s another fun experiment with pennies. You need half a cup of vinegar and a teaspoon of salt. Mix it and put the coins in the solution. The dull ones will regain their shine. If you want to keep them shiny rinse them in water, if you want to turn them green/blue put them to…

  • Surface tension experiments

    Surface tension experiments

    A great way of teaching kids about water surface tension with just a bunch of coins (plastic or real), water and a dropler. I did this with my 5 year old and she really enjoyed playing and testing, but a more understanding of the concepts would be achieved with older kids so I will definitely…

  • Erupting volcano

    Erupting volcano

    Go outside and make a mud mountain. In the middle put an used can and put half a tub of baking soda and some colour powder/pigment. When ready pour some vinegar in and watch it erupt.
