How to identify rocks.

Just like you wouldn’t look for a polar bear in a desert, there are places where flint is more likely to be found, and places where it isn’t.

This activity is suitable for Key Stage 2 – Rocks, soils and fossils. Children work scientifically by observing rocks and carrying out tests to identify and classify each sample. After the activity children should be able to: Name the three different types of rockFirst, weigh the rock on a food scale and record its weight. Next, fill a measuring cup halfway with water and note the level. Gently place the rock in the water and see how much the water rises. This rise tells you the rock’s volume. Finally, divide the rock’s weight by its volume to calculate its density.

Meteorites typically exhibit a significantly higher density compared to most terrestrial rocks.

It allows separate the most ore minerals, which have a metallic luster.Sedimentary Rocks. Sedimentary rocks (layered rocks) are made by the deposition of particles carried in air or water and by the precipitation of chemicals dissolved in water.

Igneous rocks (fiery rocks) are made when molten material inside or outside the earth cools and becomes solid. This melted rock is called magma when it is inside the earth. When magma finds its way to the surface through cracks or volcanoes, it is called lava. When lava cools on top of the earth’s surface, it forms extrusive ...Igneous rocks are formed by cooling magma. The location of the formation of the rock, as well as how fast the magma cools will determine the type of igneous rock. Intrusive rocks form from the cooling of magma deep beneath the earth's surface.
