My name is Sinéad and I will be teaching Junior Infants in September.
An interesting fact about space…..Mars has dust storms. Often called the red planet, huge dust storms can last for months and make it hard to see the surface.
An inquiry-based activity……. I’ve tried this experiment a couple of times and its very effective ……How to grow a rainbow – science experiment.
Needed: Kitchen roll/paper towel • Markers • Two small bowls of water • Paperclip • Thread
Cut the kitchen roll into the shape of a rainbow. At each end, use markers to colour a rainbow about 2cm up from the bottom…..red, orange, yellow, green, blue, indigo, violet. Attach the paperclip to the top of the rainbow and tie a piece of thread to it. This will allow you to hold your rainbow. Add water to the two bowls. Hold the rainbow with both ends slightly submerged into each bowl of water and watch your rainbow grow.
Explanation: The fibres in kitchen roll have lots of little holes. Water is absorbed through the kitchen roll because when the first water molecule adheres to it and begins to move upward, it pulls the next water molecule up with it, like a chain. This same action is how water moves up into plants from the roots.
