Classification+CS1-Ch4

Much of our study this semester on Classification will come from our Text Core Science 1 - Chapter 4 This can be accessed by students on the Intranet at: Students> Science> Science Resources> CSIStart

Introduction
Planet Earth has a great variety of different living things within it. Scientists classify these living things into groups on the basis of their characteristic features. In this chapter you will find keys to unlock the doors of classification and see how groups of living things have changed over time.

Chapter 4: C L A S S I F I C A T I O N
Fire grows, moves and uses oxygen. Is it alive? Why bother to classify living things? How can you use a key to unlock the door to classification? Are all living things either animals or plants? Vertebrates are animals with backbones while invertebrates are animals without backbones. What percentage of animals are vertebrates? Which animals have their skeletons on the outside? Which animals have gills when young and lungs when adult? Which two mammals lay eggs? Which living animal is most like the extinct diprotodon? Why do insects have a proboscis? What did prehistoric pelycosaurs use their sail-like fins for?

KEY QUESTIONS
Classify living things into major groups using structural features. Describe the changes in living things during an era of Earth’s history. Identify trends, patterns, relationships and contradictions in data and information. Use keys to identify a range of plants and animals. Describe why humans belong to the animal kingdom.

Vertebrates
Fish Dissection Prac Science Focus 1 (pp. 169-170) Study the organs of the fish and notice how they are connected and where they are. Notice the Air Sack / bladder for floatation.
