Grade 7 Physics Lessons for Spring 2022
Assessments: to be arranged
Test date: May 3 this will be delayed by one week if the school is closed
| Week number | Starting date | Lesson content | Lesson resources and links | Homework |
| 2 | 10.1 | Introduction to physics this year. Understanding heat and temperature - what are they ? How are they measured. Temperature scales | Coping with physics info sheet Lesson notes The Finnish sauna - how to survive it..... How does heat move within the sauna ? Why are the benches wooden, and not made from metal ? Why do Finnish children stick their tongues against cold metal posts ? | 1. Read the info sheet 'Coping with Physics' you were given in the lesson. 2. Click this link, watch the video and follow the instructions. |
| 3 | 17.1 | Heat and expansion. The particle model. How a liquid in glass thermometer works. | Lesson notes Types of thermometers and how they work. Particles within solids, liquids and gases. How the behaviour of particles can explain the properties of materials. Temperature survey. | Watch this video as it will go over what we did in the lesson. There is no written task with this homework. |
| 4 | 24.1 | How does heat move ? Conduction | Lesson notes Evaluating the thermometers from last week¨s lesson. How does heat move in solids ? Explaining conduction. Testing out layers of insulation. | Evaluating the experiment: . did the method work ? . can we make a conclusion ? . how can we improve it ? |
| 5 | 31.1 | How does heat move ? Convection and radiation | Lesson notes Finnish sauna heating - background reading Sauna picture Explaining convection. Importance of particles in conduction and convection. Explaining heat radiation. Colour and radiation losses Thermal image Heat loss from a human body in cold weather Fluffy bird | This form |
| 6 | 7.2 | Variables Experiment on heat loss from black and white objects. | what are variables. powerpoint presentation Thermal image Heat loss from a human body in cold weather lesson notes Investigation planning sheet Using the scientific method | |
| 7 | 14.2 | Evaluating experiments | Spreadsheet for the data How animals adapt to the cold and heat Lesson notes | over the next week, pay attention to your outdoor clothing and think about how it keeps you warm. How does it use conduction, convection and/or radiation ? No need to write anything - but it would be useful if you did. |
| 8 | 21.2 | Foil experiment. | There are no lesson notes - we started discussing conduction, convection and radiation, and how winter clothing keeps us warm. Instruction sheet Assessment criteria IB version Assessment criteria - student friendly version for grade 7 Writing frame (pdf) Writing frame as google doc - please save a copy or download it | spend 20 minutes filling in the writing frame - either the purpose part, or the apparatus or the method. The hypothesis part of the purpose is very difficult and we can have some time next lesson doing this too. |
| 9 | 28.2 | Planning and doing the foil experiment | No homework | |
| 11 | 14.3 | Doing the foil experiment | Lesson notes | 20 minutes work on your investigation, please. This could be thinking about what your results show so that you can finish your conclusion and evaluation in the lesson next week. |
| 12 | 21.3 | Writing up the foil experiment. | Lesson notes When you have finished, complete this form | No homework |
| 13 | 28.3 | Electromagnetic radiation | Reviewing the investigations. Lesson notes Why units matter. NASA Imperial and metric Light in nature Introduction to electromagnetic waves video (and a lesson in history!) Alternative video from NASA Parts of the electromagnetic spectrum and their uses. | Watch out for rainbows in the sky eg from solar halos on sunny days. |
| 14 | 4.4. | Wave properties Colour. | Last weekend's halo Lesson notes What are waves ? Wavelength, amplitude, frequency. Units. What is colour ? Short video A longer video if you would like to know more. And an old, medium length video! The dress Vsauce - colourblindness | No homework |
| 15 | 11.4 | Reflection | Lesson notes How light interacts with surfaces. Rules for drawing light rays Law of reflection | Reflection from a curved mirror. Take a shiny metal spoon and look at your reflection from the spoon when it is concave side up and then convex side up. In your notebook describe the reflections eg bigger, smaller, upside down, left-right reversed. Does it matter how far away you are ? |
| 16 | 18.4 | Curved mirrors and lenses | Lesson notes Reflection from curved mirrors and types of image - real and virtual. Refraction through transparent materials. | Study for the open notebook test. Yes, this is still far off, but get your notes sorted out. How to study for the test - click here |
| 17 | 25.4 | Going through work for the test | Lesson notes | Study for the test. This video on heat transfer might help you This website has a lot of info on heating and cooling and here for solids, liquids and gases This video is about variables Here are some quizzes to help you: Heat Finnish and English key words match Heat Quartet Cards - this needs four players |
| 18 | 2.5 | |||
| 19 | 9.5 | Test | No homework | |
| 20 | 16.5 | Refraction and total internal reflection | Video about reflectors https://www.youtube.com/watch?v=Bi_Tp1H9CDs Students can think about why we do not have these retroreflectors on roads in Finland ! Target Science Physics books p.96-97 read and answer questions p.98-99 read and answer questions To finish up watch about the 'floating' boat mirage which is caused by refraction. This is actually quite easy to see from the sea shore on a hot day https://www.youtube.com/watch?v=R-Lacu0VG3Y | |
