Geology!
Our new thematic unit comes with a new shade of fireplace. Because that is how I roll.
We started our unit with an experiment to gain a basic understanding of the the cycle of the three main rocks to be found on and in our planet.
Sediments (crayon shavings)...
...under pressure...
...make sedimentary rocks.
Sedimentary rocks under extreme pressure...
...become metamorphic rocks.
Metamorphic rocks heated become igneous rocks.
The Boy chose a selection of rocks to roll on a slope. He timed each one.
Ballet Girl weighed and compared rocks.
They completed some super work.
The Boy experimented with vinegar and rocks to see which contained Calcium Carbonate.
Those that did, fizzed and let off tiny CO2 bubbles.
Floating and sinking hypothesising and experimenting,
Identifying our collection of semi-precious stones.
Learning about rocks.
Using oats, sultanas, syrup, butter and honey as sediments for sedimentary rocks...
...to make metamorphic rocks/flapjacks under heat.
Using playdough and a straw to understand how layers form.
The Boy designed a machine strong enough to withstand extreme heat and able to explore below the Earth's crust.
