Examine a variety of objects and materials, and record qualitative (e.g., colour, texture, and state of matter) and quantitative (e.g., density, melting point, and freezing point) physical properties of those objects in a chart or data table.

Describe the characteristics of pure substances, mechanical mixtures, and solutions.

Construct a graphic organizer for the classification of matter that includes mixtures, pure substances, elements, compounds, mechanical mixtures, and solutions.

Classify common substances (e.g., Kool-Aid, vinegar, bubble bath, soft drinks, juice, chocolate chip cookies, salad dressings, hand lotion, shampoos, tea, bread, soil, and concrete) as pure substances, mechanical mixtures, or solutions.

Listen to and consider the ideas of classmates when classifying materials as pure substances or mixtures.

Create mechanical mixtures and solutions using common materials and compare the physical properties of the original materials and the resultant mixture or solution.

State the four main ideas of the particle model of matter.

Create models and/or physical representations that depict the nature of particles in pure substances, mechanical mixtures, and solutions according to the particle model of matter.

Analyze the usefulness of personally constructed representations of particles and the strengths and limitations of models in science generally.

Generate questions related to differences between mixtures and solutions and rephrase in a testable form (e.g., rephrase a question such as "How sweet is iced tea?" to "What is the most iced tea that can be dissolved in 500 mL of water at 23°C?").
