Forces

** Physics Topic // " __ Finding out about FORCES __ " //**


 * **PHYSICS is…** ||

__ Physicists __ study different types of energy. They investigate and explain things like movement, heat, nuclear energy, light and electricity. Some engineers use their knowledge of physics to make sure buildings are strong and cars are safe. Physics knowledge is also used in electronics & computer design. ||
 * The study of the behaviour of natural and manufactured things and reasons for their behaviour. Physics is concerned with movement and different forms of energy such as light, heat, electricity and nuclear energy. Branches of physics include acoustics, the study of sound.

**Learning ACTIVITIES**

__ A short investigation on Simple Machines! __
 * TERM 3 ** -Welcome back to the // final leg // of our Forces topic...

During this investigation you will learn about what a simple machine is and work in __pairs__ to investigate __one simple machine.__ You will complete an experiment and a scientific investigation report outlining the aim, prediction, material, method, results, discussion and conclusion sections for your experiment on a simple machine. You will first investigate your simple machine using the __Science Quest 2__ (chapter 5) resource to __answer questions__. You will then complete the __organiser__ for your simple machine. It's important that you do your best and work hard to understand your simple machine as you will need to help others to complete thier organiser about your simple machine. You and your partner will split up into different groups to explain your simple machine to others.
 * Your Task outlined! **

__At the end of this short investigation you will have__ completed all parts of your simple machines organiser (one per person), conducted an experiment in pairs, written a science report (use template below) and assessed your progress using a rubric. You would have collaborated with others to share your knowledge about your simple machine and completed a peer assessment about how well your partner worked.

YOU WILL ONLY HAVE A LIMITED AMOUNT OF CLASS TIME TO WRITE YOUR REPORT AND COMPLETE YOUR ORGANISER! If you use your time well, split up the tasks amongst yourself and your partner this should be achievable.

6. FINDING OUT ABOUT YOUR FORCE
 * Learning intention: ** //We are learning// to describe our chosen force for investigation through researching, summarising and note-taking to expand our knowledge and understanding of forces.
 * Success criteria **
 * In my own words, I can describe my force for investigation
 * I have taken notes to summarise key information about my force from Science Quest 1 and also using the internet. I have recorded my references.
 * I am up to/ have started typing into the introduction section of my report document.

__ Things To Do (TTD) __
 * 1) Think about how to summarise information into dot points using short sharp sentences. Focus on summarising only one paragraph at a time into one short, sharp dot point. Practice summarising as a class using last weeks homework sheet on forces.
 * 2) Read about your force in Science Quest 1, Chapter 5 (check the reference on "Step 3" document). Summarise the main points. What questions do you have? What information do you need to clarify or find out more about?
 * 3) Use the internet to try and find extra information to answer your questions. You can work with others doing the same force to share information about your force, but you must do your own work.
 * 4) Download a copy of the investigation template and begin filling it in. [[file:ScientificReport.doc]]

HOMEWORK TASK **Due Next week on Wednesday.**
 * Come to class with a real life example of a force in action. You can bring an object, a picture etc...

5. WHAT STEPS ARE INVOLVED IN A SCIENCE INVESTIGATION?
 * Learning intention: ** //We are learning to// describe the steps that are involved in a science investigation, to investigate and expand our knowledge and understanding of forces.
 * Success criteria **
 * in my own words, I can describe the science steps for investigating and have written these in my workbook.
 * I have answered questions 1-2 on page 49 of Science Quest 1
