A Week of More Geology Fun!

Understanding the layers of the earth.  Flour and coloured water...

Inner core, outer core, mantle, crust.

We are in the middle of a week long experiment: 5x freezing and thawing sedimentary, igneous and metamorphic rocks to see the effect ice has on each

Understanding the soil of our county.  We have chalk, three types of clay, sand and limestone.

 Its uses.

Making clay fossilised prints.

Earthquakes and tectonic plates.

Buildings designed to withstand earthquakes.

Unless you build right over a fault line!

The Richter Scale

Understanding sedimentary layers and density.
100ml of water, sand, cornflour and oil.

Weighing each 100ml highlighted the difference in densities. We used these to guess which layer would settle where.

It doesn't matter how much you mix them all up, they still settle in layers.

Collecting soil, stones, moss, sand and pebbles from the garden... make layers...

...add water, shake...

...and make notes on which bit settles first and how long it takes.
