Important Biological Skills (Term 1, Week 1: 15-19 February)
This section is at the start of your Study Guide in Grade 10, and also to that for Grade 12s, because these skills are so important in the subject.
Every exam that you ever write in this subject will ask you to draw a GRAPH. It gets you easy marks if you know how to do it. Be aware of the different kinds of graphs, what equipment you need to draw them, and the processes you need to follow. By the same token, if you are shown a graph, you must be able to READ it, and so explain what it is telling you.
SCIENTIFIC DRAWINGS apply mainly to our Practicals, and you need to know the rules to follow when you are drawing them. Read these rules in your Study Guides and on the Slides, and learn how to apply them. These drawings do not require you to be an artist - that is why we rely on labels to tell people what they are looking at in our drawing. You can practise these rules by scientifically drawing any simple objects - like your pen, or an apple, or a chair - and applying all the rules.
Your Grade 9 syllabus in Natural Sciences showed you how to conduct an experiment. An example we might have used was to set up an experiment to find out the average height of the kids in your class. You set up your Hypothesis - your educated guess as to what you thought the average height was. You then conducted the experiment to prove yourself right, or wrong. Your Grade 10 Study Guide (and Slides) show how you identified the Aim of your experiment, the Methods you followed in your experiment, the Results of your experiment, and the Conclusions you reached from it. Experimenting is central to all scientific subjects in order to prove a point, or to support a claim. And so you must fully understand its concept.
