Activity: to identify materials [lo 1.1, lo 2.2]

You already know that everything on earth consists of matter, (plants, animals, and non-living things) from a small speck of dust to a large planet.

A pane of glass in a window looks different from a drinking glass, but both are made from the same material, glass. Some substances may look similar and have the same colour but might differ in smell, taste, hardness, texture and elasticity. These are called the properties of materials and are used to describe the materials.

ASSIGNMENT (GROUP WORK)

• Work in groups. Look in a newspaper or magazine for a picture that shows different materials.
• Indicate the various kinds of materials that are shown in the picture and say what they are used for.

Assessment

Learning Outcome 1: Learners respond confidently to their desire to learn about natural phenomena; they investigate relationships and solve problems within the context of science, technology and the environment.

Assessment Standard 1.1: We know this when the learner plans investigations: helps to clarify focus questions for investigation and describes the kind of information which would be needed to answer the question.

Learning Outcome 2: Learners know, interpret and apply scientific, technological and environmental knowledge.

Assessment Standard 2.2: We know this when the learner categorises information: categorises objects and organisms by two variables.
