Browse our comprehensive range of KS2 Science resources. You'll find topics such as Physical Processes, Living Things and Properties of Materials. . It also includes an extension activity, which encourages children to think about how and why rocks of different hardness are used for different purposes. Answers to each question are included .

So, for example, if the quartz and the nail leave scratches on a sample but the penny doesn’t, the hardness of the sample is most likely somewhere between copper, hardness 3, and steel, hardness 5.5. So split the difference and call it a 4 on Mohs’ Hardness Scale. Write this number down in the “Hardness” column.Other activities include sorting and naming rocks, testing hardness and other properties, carrying out tests on soil samples and observing how rocks are used around the school.

what is rock hardness

Children may use a range of observational methods to assess hardness, e.g. “heaviness” of the object, and if it breaks on impact (test for brittleness), neither of which are a test for hardness. Be aware of using the correct vocabulary around testing for hardness. Explain that hardness is the ability to withstand pressure.

Understand that rocks are formed in 3 different ways. Devise comparative tests for rocks, record and evaluate observations and results. Activities. Devise their own fair test for the hardness of rocks and put a group of samples in rank order of hardness. Devise a fair test for permeability and record results and observations in tabular form.Remember, the scratch test is just one method for determining the hardness of a rock. Other tests, such as the acid test or specific gravity test, can provide additional information. However, the scratch test is a simple and accessible .

Hardness test — Scratch the rock with a fingernail, a copper penny, a glass plate or nail, and a ceramic plate. Check your Guide to assign it a rating on the Mohs Scale of Hardness. Color streak test — Test for the “color streak” of .

Objects around us are made up of different materials. Different materials may have similar or different properties. One property of materials is hardness. Ha. Rock hardness, as it has here been defined, is a function of the hardness of the component grains composing it, as well as grain size, . A simple method of making such tests of rock would be of great value to the mining industry. As pointed out by others, limestone is placed at the bottom of the scale in the tables by Gyss and Davis. .Scientific tests need to be fair if they are going to be accurate.
