Week number	Date	Lesson content	Lesson resources and links	Homework
2	6 Jan	Unit: Keeping Warm, Lesson 1 What do we mean by warm ? Heat energy Thermometers Temperature scales	Discussion on what is heat, and how it manifests as temperature. Heat is a measured in joules, and is distributed through matter and space.  We can measure temperature using thermometers.  Thermometers have a physical property which varies with temperature eg volume, resistance. Demonstrate bimetallic strip. Most materials expand when heated. Temperature scales and fixed points.	Fill in this form
3	13 Jan	Unit Keeping Warm, Lesson 2 How do we keep warm outside ? Conduction	Analysing coats, gloves and hats and how they hinder heat movement. Heat energy moves from hot to cold (temperature gradient). Conduction is limited by using insulators or poor conductors.  Different materials have different conductivity. Convection is limited by trapping gases which will move heat energy away. Trapped air is a poor conductor. Tuesday notes: part 1     part 2 Wednesday 10.15 lesson notes  part 1   part 2 Wednesday 12:30 lesson notes part 1 part 2	None set
4	20 Jan	The Particle Model	Monday lesson notes part 1 part 2 (remember we are a lesson behind on Mondays so today covered conduction) Explaining the properties of solids, liquids and gases. Task Sheet from the lesson. Tuesday lesson notes Wednesday lesson notes 10.15 12.30    Particle model video	None set for Monday Tuesday and Wednesday groups:Complete the Sheet given out in the lesson. Spend no more than 30 minutes on it - if you do not finish it, do not worry!
5	27 Jan	Radiation	Monday group - the particle model notes Explaining the properties of solids, liquids and gases. Task Sheet from the lesson. Tuesday and Wednesday group Heat radiation. Do different colours change temperature at different rates ? Comparing heat loss from black and white surfaces. Planning and carrying out an experiment. Tuesday notes Wednesday    notes	Monday group: Complete the Sheet given out in the lesson. Spend no more than 30 minutes on it - if you do not finish it, do not worry!  Tuesday and Wednesday groups List five improvements which will make your results more reliable
6	3 Feb	Radiation and convection	Monday group notes Heat radiation. Do different colours change temperature at different rates ? Comparing heat loss from black and white surfaces. Planning and carrying out an experiment. Tuesday and Wednesday  Evaluating the experiment Film showing heat loss from a human in winter Notes about radiation Convection - movement of heat in liquids and gases. Particles move apart so 'heat rises'. Tuesday group notes Wednesday groups 10.15   12.30	Monday List five improvements which will make your results more reliable Tuesday and Wednesday groups This form
7	10 Feb	Radiation and convection	Monday group: Evaluating the experiment Film showing heat loss from a human in winter Notes about radiation Convection - movement of heat in liquids and gases. Particles move apart so 'heat rises'. Monday Notes from the lesson Tuesday group - no lesson Wednesday - checking the homework.  Lesson notes (just the table) Going through conduction, convection and radiation in certain situations.  Starting the investigation. Investigation:  these files are in pdf form. If you need them in another format, contact Karin. instruction sheets writing frame	Monday group -This form Wednesday lesson - complete the investigation sheet sections: purpose and apparatus

12	16 Mar	Investigation (Monday and Tuesday) Wednesday group	Continuing the investigation - Monday and Tuesday groups only Task for those who have finished the investigation.
13	23 Mar	Home learning work	By the end of this lesson you will be able to:Task to check your understanding -  this is due before the start of your next lesson explain what the electromagnetic spectrum is know that visible light is the part of this spectrum which we use to see describe some of the properties of visible light correctly draw a light ray diagram to show reflection by a plane mirror know the rules for drawing light ray diagrams You will need your notebooks. Click on this link for the tutorial video.  sorry about the size of the screen. Video on colour and light Second tutorial video
14	30 Mar	Home learning work	Refraction - taittuminen By the end of this lesson you should be able to: explain what is meant by refraction draw light ray diagrams to show refraction give examples of where total internal reflection takes place be able to identify natural light phenomena like rainbows, haloes and light pillars list some uses of total internal reflection You will need your notebooks - during the videos I will tell you what the most important parts are to  help you take notes. Click on this link for the tutorial video. Total internal reflection video (Quantum Boffin) Optical Fibres (Physics Demos) Dispersion of light and colour video (Manocha Academy)	Task to check your understanding - this is due before the start of your next lesson
15	6 April	Home learning work	Lesson task: complete the task set from last time: Produce a short video  (less than 2 minutes) which explains one natural phenomena of light that  you have met during these lessons e.g. why the sky is blue, what a solar  halo is, how a rainbow forms. It should show the physics involved, and your   of it. You can use things you actually see at the time or images online.  Please upload the video to Teams or email it to me. When you have finished, please spend the time going through your note book,  checking you have all the work. There will be a test in week 17 (2 weeks' time)
16	13 April		Let's start with a Teams call at the start, In week 17 you will have a test. Sorry. Has to be done. Here is a list of the topics covered and some information. Here is a page of tips for studying for open note tests.  The 'study with a friend' s uggestion still works - just do it virtually ! So in the lesson, you can ask questions about the physics you have studied and we can use it as a revision. The homework will be to study for the test - there is no form to complete and evidence of your attendance of the lesson just comes from the Teams meeting.
17	20 April	Test
18	27 April	Home learning work	After the Teams Live meeting, please watch this tutorial video on Wave properties It's about 35 minutes so have a break in it and remember to stretch. This short clip should help you understand too: Transverse or longitudinal waves video This is the site of the excellent simulations  if you want to have a hunt around for more.	Then do the lesson task, which is due in next week just before you lesson.
19	4May	Home learning work	We'll start with a Teams meeting and then in today's lesson you'll look at sound. By the end of the lesson you should be able to: describe the pitch of sound using the term frequency know how sound moves in materials explain what is meant by ultrasound Sound part 1   17 mins Sound part 2   13 mins	And the learning check task is here. This is due for the start of your lesson next week.
20	11 May	Back to school !	We will go through the test, and the investigations. Breaking a glass through resonance Tacoma bridge Resonance on a rope bridge
