Keywords

  • Rock - Rock is a solid material that occurs naturally in Earth.

  • Appearance - The appearance of an object is the way something looks.

  • Compare - To compare is to look for similarities and differences.

  • Identify - To identify is to name something correctly.

  • Secondary sources - Information gathered using secondary sources is information that has been collected by someone else.

Common misconception

Children may think that rocks are all just called 'rock' and they don't have different appearances and different names.

Make sure the rock samples you give them are not actual objects, e.g. an ornament, so they are not able to use usage as a way to classify. Use a wide range of rocks that are very different so the children can identify them correctly.

Make sure you use real rocks and not images of rocks for this unit. It is important for children to handle and observe real specimens to appreciate how different rocks are. Child friendly digital microscopes will help with identifying similarities and differences.
