I understand how to make and draw a circuit, and explain how it works.

APK:

Discuss your drawings of torches from yesterday- what are pros & cons of the drawings

 

New Information 1:

ROLE PLAYING A CIRCUIT

So…how is an electrical circuit created?

A circuit needs 3 parts-

  • a cell to give energy,
  • a conductor to conduct the energy,
  • a resistor/load to use up the energy- What are some types of resistors?light bulb, bell, buzzer or motor

 

When you connect the negative end of the cell with the positive end using a conductor (wire) and have a resistor/load in the middle, you have a complete circuit. Electricity will only travel in a current if the circuit is complete and has no break.

 

A ‘cell’ contains chemicals. When the chemicals in the cell react, they release energy. This energy gives the electrons in the atoms at the negative end (electrons are negatively charged) an energetic ‘push’.

This energy is carried around the circuit by the electrons to the resistor where the electrical energy is changed into another form of energy, such as light, sound, heat or movement.

The current of electrons then continues having lost its extra energy, through the circuit to the positive end of the cell.

The circuit can be repeated over and over as long as the chemical reaction continues.

Electrons flow through a circuit and are not consumed. It is the electrical energy they carry that is changed into other forms of energy, such as heat and light; nothing is used up or consumed, just changed.

 

When a torch switch is turned on, it completes the electric circuit, making a complete path for the electrons to flow around.

 

If you don’t have a cell you have no energy to start things going …..

If you don’t have a conductor, you don’t have anything for the energy to travel along to complete the circuit …..

If you don’t have a resistor, the energy created in the cell doesn’t get used up-if this happens then the energy will come out as heat in the conductor and burn up!-this is called a ‘short circuit’– and is the major cause of electrical accidents …..

You can have many of these parts-many cells (becoming a ‘battery’)/ many conductors- wires in many parts of the circuits/ many resistors – such as a series of lights or lights and buzzers etc

Vocab: electrons, circuit, positive and negative terminals, battery/cell, switch, movement, light and sound resistors, conductors and insulators, chemicals, chemical reaction, current short-circuit

more information available here if students want to clarify or research further:

eSchooltoday

Discuss and make connections to the role play- what parts were what?

Application 1:

Draw a circuit from the demonstration and explanation

New Information 2:

Scientists use a series of symbols to represent the parts of a circuit- why do you think they do this?

Show symbols (students paste in books):

Discuss open/closed switch & difference between cell & battery.

Discuss what voltmeter & ammeter might measure. (not needed at this level)

 

Look at these 2 diagrams- T&T- what are the similarities & differences

Which do you prefer? why?

Which do you think scientists prefer? why?

It is important to draw circuits with clean straight lines, as shown in diagram B. Scientists avoid realistic sketches like diagram a-why?

Application 2:

Student review their cutaway diagram of how a torch could work from the last lesson and update or redraw this diagram to include what they now know, such as names/symbols of parts and the need for a complete circuit for the torch to light.

 

Share & discuss

 

 

NOT LIKE THIS ONE-

MORE LIKE ONE OF THESE-

 

 

 

 

 

Application 3:

Introduce snap circuit sets. Show how the symbols for the items are ON the items. Show how they snap together and the many possible circuits that can be created.

In groups of 3 or 4, students should make a circuit using circuit items available.

Once made, student & tested (troubleshoot where necessary), students should make a technical diagram of their circuit using the symbols they have learned. They should give it a title saying what it does. (Students should have labeled the basics – cell/battery, wires, item that uses power/switch

IT IS IMPERATIVE THAT STUDENTS ARE DILIGENT NOT TO CREATE SHORT CIRCUITS- NO BATTERIES SHOULD BE PUT IN PLACE IN THE CIRCUIT UNTIL IT HAS BEEN DRAWN AND SEEN BY A TEACHER TO ENSURE AGAINST SHORT CIRCUIT.

Circuits should then be tested and troubleshot if necessary

If there’s time, students can make another circuit

Year 6 Valedictorian Speech

Image result for graduation primary school clip art

As part of finishing primary school, all year 6 students will write a valedictorian speech. Your speech will be about your time in primary school. Think about all the experiences you have had at Moonee Ponds Primary School and all the wonderful things you have done.

The internet is full of tips for writing a valedictory speech. YouTube also has many worthwhile samples.

Here are some suggestions

  • Keep it in perspective.
  • Avoid trying to write something that doesn’t reflect your true self.
  • Be open to what the rest of the grade is thinking.
  • Create an introduction.
  • Thank those people who have made a difference in your life and the lives of other students.
  • Add in memories.
  • Acknowledge others.
  • Stay out of cliche zone.

To fully unpack each of these go to: http://www.wikihow.com/Write-a-Valedictorian-Speech

The website about education(http://homeworktips.about.com/od/speechclass/qt/valedictory.htm) also provides advice around:

  • Know Your Purpose
  • Compile a List of Highlights
  • Writing the Speech
  • Use Anecdotes and Quotes
  • Plan for Time
  • Tips for Preparing to Speak

Finally http://grammar.yourdictionary.com/style-and-usage/writing-your-valedictorian-speech.html has general tips for Valedictory Speeches including how to begin writing it, getting feedback and involving your peers.

For an example of a recent speech given at an MPPS graduation check out http://grace2012.global2.vic.edu.au/

Adaptation Project – Species Specialist

WHAT WE ARE LEARNING- THE VICTORIAN CURRICULUM STANDARDS

Science Knowledge

Biological – Science Understanding

  • Living things have structural features and adaptations that help them to survive in their environment
  • The growth and survival of living things are affected by the physical conditions of their environment

Science Inquiry Skills

Questioning and predicting

  • Create questions that lead into a scientific investigation, and predict what the findings of an investigation might be based on previous experiences or general rules

Planning and conducting

  • Plan an investigation to answer questions and use equipment, technologies and materials safely, identifying potential risks
  • Decide which variables should be changed, measured and controlled in fair tests and accurately observe, measure and record data

Recording and processing

  • Construct and use a range of representations, including tables and graphs, to record, represent and describe observations, patterns or relationships in data

Analysing and evaluating

  • Compare data with predictions and use as evidence in developing explanations
  • Suggest improvements to the methods used to investigate a question or solve a problem

Communicating

  • Communicate ideas and processes using evidence to develop explanations of events and phenomena and to identify simple cause-and-effect relationships (VCSIS088)

 

Personal & Social Capabilities

  • Reflect on how personal strengths have assisted in achieving success at home, at school or in the community
  • Describe what it means to be confident, adaptable and persistent and why these attributes are important in dealing with new or challenging situations
  • Describe the characteristics of respectful relationships and suggest ways that respectful relationships can be achieved
  • Identify the characteristics of an effective team and develop descriptions for particular roles including leadership, and describe both their own and their team’s performance when undertaking various roles
  • Describe the various causes of conflict and evaluate possible strategies to address conflict

OUR FINAL PROJECT

To conclude our science unit on adaptation students will prepare an information display and presentation with supporting resources on a desert animal or plant. The audience for this presentation will be other Year 5-6 students. The purpose is to inform/teach.

You will need to complete:

  • An information report (either a poster or powerpoint
  • Annotated diagram
  • Model of your species
  • Proposed experiment

Before beginning and during the process teams must allocate roles and monitor progress.

Teams should assist one another to manage tasks and time and remind each other of their personal responsibilities. All team members must be responsible for at least one aspect of research and presentation.

There should be recognition of balancing the responsibilities between team members.

Your presentation should:

  • describe the desert environment to which the species is adapted
  • describe the structural features and behaviour of the species
  • make claims about which are key adaptations that help the species survive.

Your presentations will be showcased during the last week of term where each team member will have to share their knowledge, answering questions from other students.

Examples of oral presentations by scientists on adaptations can be found at:

Museum expert presentations

 

Present your research on a display board or in digital format.

(example only- yours may look different)

Show what you know about writing information reports- features and style. You will have access to and be marked according to this Rubric for species research project

 

Note taking:
Take notes from at least 3 sources before using these notes to draft your report in your own words.

Drafting & Publishing:

  • The language of your report should be impersonal and contain three tier words.
  • Use a font size of at least 16 points for the text on your display board, so that it is easy to read from a few feet away. It’s OK to use slightly smaller fonts for captions on picture and tables
  • The title should be big and easily read from across the room. Choose one that accurately describes your work, but also grabs peoples’ attention.
  • Graphic features- Use photos or draw diagrams to present non-numerical data, to propose models that explain your claims. Try to find or create a graph to illustrate an aspect of your learning. (you could use Excel)
  • Include an annotated drawing to identify the adaptations of your plant/animal (similar to the one on ‘Camel features’)
  • You should also construct a 3D model of your plant/animalas well as your annotated diagram
  • The diagram and model should highlight the features and adaptations that are central to your species’ survival in the Australian desert. Where possible, structural features on your model should be created to clearly show how the feature works to help the animal survive.
  • A Bibliography. At least three sources.

Experiment!

Your group should include a  proposal for an experiment to investigate if your claimed structural feature of the animal/plant is an adaptation for surviving in a desert environment. You will use your knowledge of models, variables, controls and fair testing that you learned during our 2 experiments this term. Deciding on what you and your team think you can achieve in the given time, you can either:

  • propose an investigation (include mention of what variables will be tested and what variables will be controlled)
  • plan the experiment (using the template we have used in our previous science experiments)

experiment-proforma

  • conduct your experiment and observe, record and share the results in your final display. Would you change or improve your experiment if you did it again? What might be another experiment that could be carried out to extend knowledge of this area?

Annotated Digram and Model
You will need to include an annotated diagram of your species. You will also need to make a model of your species that includes annotations to identify and explain key adaptations.

Adaptations Reflection

First you should look through the Rubric we have been using and identify with a highlighter or pen what you achieved.

Then look at the post that was created at the beginning of the Unit-here

At the top there are are 3 areas in blue that describe the opportunities you were given for learning:

  1. Science Knowledge
  2. Science Inquiry Skills
  3. Personal and Social Capabilities

During your reflection you should reflect on something you learned from EACH of these areas at least once.

Write a reflection of what you have learnt during this term’s Science unit and project. Your reflection must include:
Section 1
An introduction summarising the project and what you achieved with your team-mention here items from the rubric that you feel you did well or could have improved on. What overall level did you achieve and why do you think that?

Then include:

  • Three facts that you found interesting or surprising.
  • Two understandings you now have.
  • One wonder you still have.

Section 2
Next, refer to your learning throughout the unit (in the whole class lessons, in your research pairs, at the excursion, and in science experiments) and answer:

  • What were the most important things I have learnt.
  • How did I learn it.
  • What am I going to do with what I have learnt.

To conclude create a statement that summarises what you have learnt in both section 1 and section 2 and a goal you have for the next time you work in a group.
Look at Adriana’s and Anton’s Term Three Project Reflection from when they completed this unit when they were in Year 5 to help you get an idea of a standard to reach for:
Adriana’s reflection

Anton’s reflection

Note that these reflections use full sentences and paragraphs. Both these reflections include an extra paragraph where they reflect on goals they had set at the start of the unit. As we did not do this, you don’t have to include this section.
