These printable worksheets are designed to cover the Science learning area of “Natural and Processed Materials” with 8-10 year old students. At this level the students are aware of the materials around them and should be able to identify and assess the properties of materials. Students will be involved in making close observations, collating information and assessing materials and their suitability. Tasks include altering common materials and determining whether the change is reversible or not, as well as undertaking a magnified study of some everyday cooking materials. Activities also include a look at food processing, including how the properties of food can change, and an analysis of the materials used to make a bicycle.
