Students investigate which materials are good absorbers of sound and which are good reflectors of sound. This lesson sequence is designed to exemplify a careers-linked approach to practical work, using careers-related information to provide a context for practical work. There are many occupations in which people work with sound. For example, environmental officers may need to measure sound levels (or noise), and concert hall designers may need to control the absorption and reflection of sound.

This lesson is designed to exemplify an argumentation approach to practical work, using a predict, observe, explain framework. Students make observations about the places where woodlice are usually found and use this evidence to evaluate various claims about woodlouse behaviour. They discuss how a claim (or idea) is supported by evidence (or data) and develop arguments based around these claims. The students’ focus during the practical work should be on using the evidence collected to evaluate these claims, rather than on the practical methodology.

Students will study and interpret data about changing snail populations using ideas about natural selection and make predictions about how populations might change in the future.

Students use grains of rice to models small organisms and students acts as predators selecting food during limited time spans. Over a number of generations, the proportion of grains of rice of each color in each population will change if the students select one color in preference to another. This is a simple model for natural selection resulting from predation.

Students will view videos of animal actions and behaviors and consider these actions in terms of their consequences for the animal, such as its well-being, survival and reproductive success, and also in terms of how they come to happen - are they instinctive and automatic actions or learned and deliberate? Students will also complete an observation of a real animal.
