Hi,
My name is Rohana and I am teaching Senior Infants this year. I love Science and I am looking forward to learning news ideas to implement in my class this year. The interesting fact on space is about shooting star and how they are made up of various different colours based on what they are made of.
An inquiry-based lesson that I have used in my class before is the Dancing Raisons experiment. The children absolutely loved this during Science Week last year. You fill up a glass with still water and put a handful of raisons in. The children observe what happens to the raisons. No movement takes place. Then we fill a glass with fizzy drink like 7Up/sparkling water and put a handful of raisons into this glass. The children watch what takes place. The raisons begin to float and dance.
In the glass of still water, the raisons sink because the raison is denser than the water. In the fizzy drink, the raison is denser than the water but the bubbles get trapped in the indents of the raison. This makes them float up to the top of the glass. Once the bubble bursts, the raison sinks back down. The children loves predicting what would happen and they got so excited once the raisons started floating up and down.
