Sampling techniques

Lesson idea. A comprehension and discussion activity based on four different organisms: the butterfly, the oak, the whale and the zebra.

Teaching approach. This lesson offers students an opportunity to use their existing knowledge to analyse a ‘real scientific publication’ and its language^(ta) and link this to scientific method^(ta).

• They use study skills^(topic) to skim read, make sense of complex language, and use visualisation^(ta) to select relevant information
• They engage in collaborative^(tool) group work^(ta) using reasoning^(ta) and skills in peer assessment^(ta)
• They engage in dialogue^(ta) and questioning^(ta) to explore ideas together
• They also think about how to present information using ICT⁽ⁱ⁾ tools)

Learning Objectives	Describe sampling techniques used to assess the population size of more than one organism Explain the advantages of a special sampling technique when compared with other methods Communicate the results and conclusion of the supplied articles on sampling populations
Format / structure	Each organism has 4 documents where N represents: B (Butterfly), O (Oak), W (Whale) or Z (Zebra) N1 – Leading questions N2 – Differentiated material N3 – a word document copy of the web-based article if no ICT is available or if the article is not available online N4 – a truncated word document of the original article to be used as differentiated material. The text contains the parts relevant to answer the leading questions from the original article
