This unit explores the differences between species and how to interpret observations and data to identify patterns and draw conclusions. It also focuses on making and recording observations using various methods, evaluating their reliability, and suggesting improvements for investigations.
Lesson Summary
You will learn to explain how to use a classification key, and the importance of classifying organisms into groups within larger groups.
Key Notes
