A ppt to help children identify a sample of 8 rocks/minerals based on their properties.

The rocks included are: flint, sandstone, feldspar granite, quartzite, slate, diorite, chalk and galena - but they could be edited to suit the rocks you have available.

I would print out the first slide for the table groups, large, and print out the information 2 slides per sheet to accompany the rock samples. Children can physically place their rock samples on the correct rock pictured.

This activity would accompany a lesson where children have to sort rocks based on their appearance and properties.

I would ask children to read the information sheet - if it says it’s a hard rock, they can perform the scratch test and see for themselves if this is true. If it says it is permeable, they can place sample in a beaker of water and look out for bubbles forming on the rock etc.

**Note: **Our rock sample kit contained galena already - I have researched carefully, and it is not considered a risk to handle, but I have taken the precaution of asking children not to perform the scratch test on this mineral. (Just in case you were wondering!)

I hope this activity is of some help. :-)
