Junior Infants Colourful Skittles Experiment
Our Investigation: The boys in Ms. O’Donoghue’s class were learning about the different changes water can have on a variety of materials. In this experiment we discovered that water dissolves sugar. The question which was posed to the boys was ‘What do you think will happen to skittles if we add water to them? We discussed that skittles are a type of sweet and would contain lots of sugar. The boys then predicted that the water would take away all of the colours from the skittles and the water would be colourful, as a result.
Materials: White paper plates, skittles, water.
Method: We began by sorting the skittles. When I asked the boys how should we do this they answered ‘by colour’. The boys then organised the skittles by colour and then in their pairs, they decided on a preferred pattern to place around the rim of the plate. Every pair, decided on different patterns, classifying the skittles by the same colour or different colours. They carefully poured water into the centre of the plate and watched in amazement by what was happening.
Result: Like the boys had predicted, as skittles are coated in food colouring and sugar, when you pour water over the skittles the coloured coating dissolves spreading through the water, making a colourful patterned rainbow on the plate.
- Maths- Early Mathematical Activities; Classifying. The boys classified the skittles on the basis of an attribute i.e. colour
- Maths- Algebra; Extending Patterns. The boys identified, copied and created patterns in colour with their skittles.
Mathematical/ Scientific Language: Our key word for the experiment was ‘dissolve’ we talked about many other examples where water can dissolve a material i.e. sugar in your tea. The colours were also discussed, red, green, purple, yellow, and orange as well as incorporating our knowledge of 2d shapes- the circle.
