Year 9 Assessment Task 1:

Electrical Circuits

Name:_______________________ Class:___________

Weighting: 25% Due Date: _________________________________________ Outcomes: SC5-2VA shows a willingness to engage in finding solutions to science -related personal, social and global uses, including shaping sustainable futures. SC5-4WS develops questions or hypothesis to be investigated scientifically SC5 – 6WS undertakes first-hand investigations to collect valid and reliable data and information, individually and collaboratively 8C5- 9 WS presented science ideas and evidence for a particular purpose and to a specific audience, using appropriate scientific language, conventions and representations SC5-10PW applies models, theories and laws to explain situations involving energy, force and motion SC5- 11PW explains how scientific understanding about energy conservation, transfers and transformations is applies in systems Task description: Throughout the topic of electricity you will meet various learning goals. During the unit you will create an instruction book for someone who wants to learn basic information about electricity. During the unit you will work in teams to construct real circuits and investigate how different ways of setting up a circuit affect power output. Your assessment will be based on how easy it is read, follow and understand the information presented in your book The book will require:

- A title page

- Contents page

- Key for components and their use o Images and scientific diagrams with explanations

- Instructions and diagrams of how to construct series circuits pointing out advantages and limitations of this set up.

- Instructions and diagrams of how to construct parallel circuits pointing out advantages and limitations of this set up.

- Diagrams and instructions of a circuit used to demonstrate OHM’s Law

- Create a graph that demonstrates the relationship between current voltage and resistance

- An analagous diagram that uses a water tank/pipes/pump narrowing of the pipes (or another analogy) to help explain how an electrical circuit works

- Instructions and diagrams of generators and electric motors to demonstrate transformation of one energy type to another.

- Develop a persuasive text about a particular type of renewable energy identifying its short and long term benefits, you may wish to discuss things like environment, cost, employment and natural resources, and argue the importance of these factors on our future.

Each student will hand in their own book, however, collaboration with peers is encouraged to maximise learning outcomes. Outcome 0 1 2 3 4 5

a particular type of renewable energy is presented in a manner that demonstrates some research

about a particular type of renewable energy is presented with some data and evidence of valid research (bibliography)

about a particular type of renewable energy is presented, with valid data and evidence of more than one source of research to back up statements. (bibliography)

Written in a logical manner

Non attempt

Argument is written in a few statements

Argument forms a paragraph

Argument is formed with a series of points

Argument is formed with a series of points that are written as separate paragraphs

Persuasive text Your goal is to persuade people that renewable energy is an important resource for the future, give reasons for their importance and the particular one you have chosen and back them up with some facts and examples. The Position: States what the issue or topic is

States what you think about it Can use a statement that attracts attention

Arguments: Why should people believe you and accept your position?

Argument 1:

because

Argument 2: because

Argument 3: because

Summing Up: Strongly repeats what you believe with a summary of reasons why.

Now each argument on the previous page represents a paragraph of writing for your piece of writing. So for your Argument 1 you need to discuss it in the following form:

Sentence 1: The Point P

Sentence 2: Elaborate E

Sentence 3: Evidence E

Sentence 4: Expand E

Sentence 5: Link Back L

Now let’s put it all together PERSUASIVE WRITING SCAFFOLD: ‘Renewable energy is going to be an important resource for our future’

Introduction: The Position:

Paragraph 1 – Argument 1. P E E E L

Paragraph 2 – Argument 2. P E E E L

Paragraph 3 – Argument 3. P E E E L

Paragraph 4 – Argument 4. P E E E L

Conclusion: Summing Up

Now write your persuasive text properly.
