Science 'Our Violent Earth' - Year 6
Our Year 6 students enthused over making a Volcano model with a difference this week.
After making models of the layers of the Earth, we showed how the hot magma tended to move and cause the 'floating' crust to collide into other plates in the crust. The resulting friction tended to result in earthquakes and volcanoes.
Instead of using good old bicarb and vinegar, the students made a recipe of 'Elephant’s Toothpaste' lava. Later, they made a different model by heating a layer each of red crayon, sand and water to simulate the molten rocks oozing up through the crust and under the ocean to create new islands and red land!
The effect was visually quite surprising and authentic. The students loved this type of learning!
