Mini Teaching Tips for this week…
I Can Grow a Rainbow
Have fun learning about liquids and materials with this cool experiment…
The kitchen roll is made up of lots of tiny plant fibres which absorb liquids very well, making them great for mopping up spills in the kitchen. As the water soaks into the paper towel, the water starts to move through pockets in between the fibres lifting the dye molecules along with it. The water continues to move through the pockets in the dry paper and so the dye starts to bleed its way along the paper creating a rainbow effect.
A great opportunity to talk about liquids, gases and solids and their properties.
Also introduce scientific vocabulary such as:
Refraction, Reflection, Light, Spectrum, Rainbow, Colour, Solid, Liquid, Gas, Evaporation, Condensation, Particles, Temperature, Freezing, Heating,
Hard, Soft, Stretchy, Stiff, Shiny, Dull, Rough, Smooth, Bendy, Waterproof, Absorbent, Opaque, Transparent Brick, Paper, Fabrics, Squashing, Bending, Twisting, Stretching Elastic, Foil, Hardness, Solubility, Transparency, Magnetic, Filter, Evaporation, Dissolving, Mixing
