Last week I gave out a summative assignment (a presentation on waves) to 10C, but was unable to give it to other classes due other classes being cancelled.

In light of this, and the Grade 10 Science test on Friday (3oth September) I have moved the due date for the waves assignment (when presentations will begin) to Monday October 10th. This will mean that presentations will be made during the week of the 10th of October, giving everyone a week to prepare their presentations after the test.

I will give the instruction sheets to 10B on Wednesday (28th September) and 10C on Thursday (29th September),  and post it below. With the exception of 10C (who will hopefully already have started) I don’t expect anyone to make significant progress on this until after the test on Friday.

The test will cover waves theory, sound and the electromagnetic spectrum. It will not cover the first class on light which everyone has done.

Waves Project:                  Summative Task1

Aim: To research as a team and show to the class a computer-based informative presentation on one of the following: The science criteria assessed will be Knowledge and understanding in science (KUS), Reasoning in science (RS) and Attitudes in science (AS).

Seismic waves; Wave power stations; Ultrasound; Fibreoptics; Telescopes; Tsunami; Microscopes; Radio; Lasers; ; Solar radiation

The areas of focus for your research should be: What it is? How it works? The history of it? For most topics you should also consider its uses and/or hazards. (not all appropriate for all topics)

Waves are the key to each of these topics – Make sure you discuss how the properties of waves relate to your subject. E.g. wavelength, speed, frequency, transverse  or longitudinal. Reflection, Refraction and Diffraction should also be referred to if relevant.

You will be expected to document your research and reference your sources.

Format of presentation:

Your presentation should be divided into the following sections:

Introduction (~30 seconds)

In the introduction you should introduce yourself and the topic you will be discussing. This means briefly mentioning all of the main points you will talk about in the body of the presentation and the relevance of waves in your subject area.

Body (~3 minutes)

In the body you should logically explain your topic. You should try to make three or four main points. Explain each point using clear scientific language and link them together. You should use images in your explanation. You should discuss and use examples to illustrate your points.

Conclusion (~30 seconds)

In the conclusion you should summarise your main points. You should also discuss the significance of the points that you made and the topic in general.

Questions (~2 minutes)

During this section the teacher (and other students) will have the opportunity to ask you questions about your topic. This is to determine how broadly and deeply you understand the topic. Keep your answers brief, and if you do not know the answer it is better to say so rather than make up a response.
