In our daily life in Ghana, we constantly meet mixtures: *kenkey dough (corn dough + water), gari and sugar, sand and stones at a building site, palm oil and water in soup, Milo in water, fruit juice, muddy water after rain*. Knowing the types of mixtures helps us to: choose the correct method to separate them (e.g., sieving, filtration, decantation, evaporation), understand solutions like ORS, salt solution, and drinks, improve hygiene and safety (e.g., treating water, removing dirt). This lesson focuses on the indicator B8.1.1.1.1: Identify types of mixtures by observing and describing their characteristics.
A. Matter and Materials (Quick Reminder) Matter is anything that has mass and occupies space. Materials are substances we use (e.g., salt, sand, water, oil, sugar, gari, gravel). B. Classifying Materials: Solids and Liquids Solids Have a fixed shape and fixed volume. Do not flow easily. Examples: *salt, sugar, sand, gari, gravel, pebbles, bottle tops*.
Liquids Have fixed volume but no fixed shape (take the shape of the container). Flow easily. Examples: *water, oil, vinegar, fruit juice*.
Class Activity Idea (from NaCCA exemplar): Give learners samples: *powder, pebbles, bottle tops, salt, sugar, sand, gari, gravel, oil, water*. Learners sort into solids and liquids and justify their choices.
C. What is a Mixture? A mixture is formed when two or more substances are combined physically (not chemically). Key points: Components keep their original properties. Components can usually be separated by physical methods. Mixtures may be uniform or non-uniform.
