Objectives:
Define the three different methods of heat transfer
Give examples of a number of different dishes and which methods of heat transfer they use
Tasks:
Watch the videos - the video will help you to complete the work but will also give you extra information, please take the time to watch them
Write out the glossary terms
Fill in the gaps or write out the whole paragraph (DO NOT just write out a list of words)
(Draw out and) Complete the table
Draw the different methods of heat transfer

Please watch the lesson video part 1:
Make a new glossary page if you don't have your folder, if you have your folder please write these on your green glossary page.
Write out the glossary terms –
Conduction: transferring heat through a solid object into food.
Convection: transferring heat through liquid or air into food.
Radiation: transferring heat through infra-red rays which directly cook the food.
Write out the paragraph, filling in the gaps with the words below:
radiation convection conduction grill three
metals water convection currents
There are ………………………………. ways that heat can be passed to food during cooking. They are ……………………….., ………………………… and ……………………………… .
During …………………….., heat passes from molecule in liquids or solids. Some materials conduct heat easily and they include ………………………….. and …………………………. .
In …………………………., heat travels around the food in currents. These are called ………………………………. …………………………. . This can happen in liquids and inside an oven.
Through ………………………………, heat travels in waves or rays that heat up food. This method of cooking requires direct contact (not necessarily touching) with a heat source such as a ………………….. .
Watch the lesson videos part 2:
Watch the videos and guess which method of heat transfer I am talking about
Watch the lesson videos part 3:
Read the following statement and fill out the table:
Most food is cooked by a combination of methods of heat transfer. For example when baking a tray of biscuits, the heat is transferred to the biscuits by conduction from the metal baking tray, also the heat is transferred to the biscuits by convection using the hot air inside the oven. Using this example to help you, write out and complete the table below.
Cooking method: Methods of heat transfer: Biscuits conduction, convection
Stir-frying vegetables
Boiling an egg
Baking a potato
Toasting bread
BBQ a chicken thigh
Roasting beef
Please email me this table by the end of Tuesday 28th April - on either a word document or a photograph of them written out.
Watch the lesson video part 4:
This can also help you to remember, draw the different methods of heat transfer:
Tip: think about the animation clips and the PowerPoint slides and the pictures I pulled from the animation clips. I would love to see some of your drawings but I will send you my drawings as part of the feedback.
Feedback: I will be giving general feedback this time and it will be emailed to you on Thursday
FAQs: Don't forget I'll be on my email (kconnett@taptonschool.co.uk) to instantly respond to questions between 12-1pm on Monday. If you can't get on to email at that time, please email your questions over the weekend and I will add it to the FAQ section here.
