Pose questions about characteristics and uses of common materials.

Distinguish between objects and materials found in nature and those constructed by humans.

Observe natural and constructed objects and materials in their environment in a safe and respectful manner using all their senses as well as technologies, such as hand lenses, cameras, and microphones, which enhance the senses.

Record relevant observations about common objects and materials using written language, pictures, and tables.

Compare the properties (e.g., texture, colour, smell, hardness, and lustre) of materials that appear in familiar natural (e.g., tree, lawn, rock, and creek) and constructed (e.g., clothing, toys, electronics, furniture, and buildings) objects.

Distinguish between the materials used to construct an object and the object itself.

Predict the characteristics (e.g., hardness, insulating ability, water resistance, absorbency, and flexibility) of common materials and carry out a procedure to test those predictions.

Explain why the characteristics of materials help to determine their usefulness within different objects.

Evaluate the suitability of materials for a specific function.

Sequence or group materials and objects according to one or more properties such as texture, colour, smell, hardness, and lustre.

Analyze how common objects and materials are depicted in texts, pictures, and videos.

Suggest alternative uses for common objects and materials.

Generate conclusions about the properties and uses of materials based on personal observations and investigations.
