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? […]
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 […]
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.
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.
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 […]
