Group presentations

Today we will be working in groups of two on presentations for tomorrow. They will go for no more than 2 minutes each and will deal with one question about this topic. Some will be about heating, and some will be about magnetism. The tasks for today are:

1. Organise a group of two and get a question from Mr. Cole.
2. Find information on the internet or in your books about your topic, and make sure you understand it!
3. Make 2-5 powerpoint slides about your topic, and write a script so you will know what to say. 
4. Practice your part so you know what to do, there will be prizes for good presentations!!

We will present these tomorrow in J18, so make sure you come on time. For homework, read over your section so you know what you will say in front of the class.

4. Why is a convection oven better at cooking? 
5. Watch this video. Explain how Heston uses conduction, convection and radiation to create the meal:
6. Think of your favourite hot food. Find a picture of it, and put it on a powerpoint slide. You need to use arrows and axplanations to show HOW the food is heated (by conduction, convection, radiation, or more than one) and where the heat comes from. Save this and we will print it if we can.
