Safety rules Area of Interaction and Phys/Chem || || Questions on the safety rules || For next lesson || Forces as pushes and pulls: interactions between objects. Measuring forces using newtonmeters. The unit of force. Representing forces using arrows to show direction and size; vectors. Newton's 3 laws. || Ilmiö p.151-157 || Read through your notes from the lesson to check you understand ||  || Experiment. Using data to draw a graph and make a conclusion. || Report writing frame || Complete the graph, conclusion and evaluation || For next lesson || An investigation which you will plan in pairs and carry out to find out if you the changing the concentration of salt in water will increase the upthrust of the liquid, and if this could be used to measure force. This task will be assessed for criteria B,D,E and F. The criteria are available from the link at the top of the page - you need your username and password. || Task sheet Report writing frame || Complete the experiment report || 10.20 on 24/9/2012 Paper copy or emailed attachment || Watching the video 'Freefall' || Ilmiö chapter 3 p151 || Qn 10 & 11 p. 157 || For next lesson || g forces. Mass and weight. Balance and centre of gravity (mass) || Ilmiö chapter 4 p. 160 Ilmiö chapter 11 p. 207 || Read chapter 11 || For next lesson || Finding the centre of gravity of 'Finland' Use a cut out map of Finland, and hang it from three points. Mark on the vertical lines which pass through the centre of mass. Mark these on the map and where they cross should give the centre of mass. || We found the centre of mass to be between Pyhäntä and Kestilä. || Method, results, conclusion and evaluation for the centre of mass experiment || For next lesson || Pressure - understanding what the physics term means P=F/A Consequences and examples of pressure: snow shoes, thumb tacks Atmospheric pressure, tyre pressure Units N/m2 or Pa but there is a variety of other units (see Pressure units sheet) Discussing Felix Baumgardter's incredible jump and the issues about pressure in his fall. || Ilmiö chapter 5 Tiheys p. 167-172 Ilmiö chapter 7 Paine ja noste p.179-182 Pressure units || Qn p.185 1,2,8,9,10,11 //For English translations, click the link at the top of the page and these questions are at the end of chapter 7 Paine ja noste.// || For next lesson || Ilmiö chapter1 p. 135 Uniform motion Usain Bolt sprint data d-t graph Usain Bolt's 100m record, Berlin 2009 || p.185 Qn 8,10,12 || For next lesson || Ilmiö chapter 2 p.143 ||  ||   || F=ma; calculations using Newton' second law || Some simple calculations || Revision for the test (10/12) The test covers everything we have learnt. In Ilmiö, it is chapters 1 to 9 and 11 of the Liike ja Voima section. Ilmiö has some useful 'Muista!' sections at the end of every 2 chapters. These are also available in the translations. ||  || We also look at how knowledge of these is used to make rollercoasters.
