My name is Rebecca. I will be teaching 1st class this coming September. My favourite space fact is that depending on the elements shooting stars are made from they can shine different colours.
An inquiry-based lesson that I have done is making a volcanic eruption in a jar. The children really enjoyed this and it is such a fun way to show chemical reactions in the junior classes.
Method:
Half-fill a jar with water.
Add a few drops of food colouring.
Fill the rest of the jar with oil.
Allow a few minutes for the oil and water to separate.
Drop the fizzy tablet and watch the magic happen.
