The last two of these are much less well known. There are currently five different states of matter that have been identified: solids, liquids, gases, plasma and Bose-Einstein condensate. Other properties of materials can include their viscosity and conductivity.Ī commonly talked about property is the state or phase of matter. Use this activity to learn more about density. These are some of the metal’s properties. Testing shows that this material is able to conduct heat and electricity and that it will react with an acid. For example, if we have a sample of metal in front of us, we can identify that this material is grey, hard and shiny. When we refer to the properties of a material, we are talking about features we can sense, measure or test. Some other fascinating, less well known materials include nanofibres, biological materials and composites. Investigate the properties of wool and how they link to its uses in the student activity Exploring wool fibre properties. Wool is another traditional material that has undergone innovation. You can learn more in the article What are minerals? These inventions require scientists to understand the properties of minerals. Some examples of everyday materials are plastics, metals, fabric and glass.įind out more about plastic products in the article Plastics and recycling.įind out more about metals and what happens when they mix in the article Metals, alloys and metal compounds.Ĭeramic materials are used to make traditional pottery, right through to advanced ceramics used in engineering and medicine. There are many different types of materials. Scientists, technologists and engineers investigate these materials – they experiment with them, compare their properties and relate the results to possible uses. These materials make up the objects around us, and each of these materials has different properties or characteristics that can be observed or tested.
