Students study the various sources and uses of natural and synthetic materials to explore the building blocks of all matter. They examine and classify synthetic and natural materials found in their environment to make generalizations about their properties and usefulness. They compare the environmental impact of their use. Students identify objects made from common elements such as gold, silver, iron, and aluminum, and describe characteristics of these elements, such as colour, lustre, and magnetic properties.
Students bring a selection of natural and synthetic materials found at home and at school.
Students investigate to determine which of the materials collected can be recycled, renewed, and conserved. They identify an environmentally friendly alternative, support their decision with evidence, and make a presentation to the class. They demonstrate their ability to apply scientific skills and processes when they identify attributes and classify materials, examine consequences of using synthetic and natural materials, develop environmentally friendly options, and conduct surveys. Skills and processes Students work independently or with a partner to examine a collection of natural and synthetic materials that have not previously been discussed in class. Knowledge Students create a Venn diagram to compare and contrast natural and synthetic materials that could be used for the same function.
