SHS3 Biology · Semester 2 Week 5: Ecology

Lesson notes

Learning Objectives

Indicator: 3.3.2.LI.2 - Draw valid conclusions and inferences on the analysed data.

By the end of the lesson, learners can:

Distinguish between a conclusion and an inference when interpreting ecological data.
Draw valid conclusions from at least two sets of analysed ecological data collected in earlier weeks (plant density and Body Mass Index).
Make logical inferences from graphed data that go beyond the immediate observations.
Justify each conclusion and inference with specific evidence from the analysed data.
Recommend at least one practical action or intervention based on the conclusions and inferences drawn.
