Listen and check.
Hot liquids rise. Hot gases rise. If you heat a liquid, it expands. If you push a liquid or a gas into a smaller space, the pressure rises. If you release a liquid or a gas into a larger space, the pressure falls. If you put more energy into a solid, a liquid or a gas, it gets hotter.
079 Unit 6, The mother of invention Exercise B
Listen to Part 1 of the podcast and check your ideas. Logan: Hi, everyone, and welcome to this week’s podcast from
inventit.com, the podcast that helps new inventors. You can find all the show notes under the podcast tab on the website, and I’m also on Facebook and Twitter, of course.
Every year, inventors patent 80,000 inventions in the USA. Patent means register with the government. It’s a way of protecting your invention. You send drawings to the US Patent Office and then no one else can say, ‘I invented that first!’ Most of the patents are from companies, not from individuals – you know, companies not people. Unfortunately, most of these inventions – from companies and from individuals – never make any money. Less than 1%, in fact. So, this week, we’re going to talk about becoming an inventor. Later in the podcast, I will be talking to Celia Jones. She has an idea for a new household appliance. A household appliance is a machine used in the home, usually in the kitchen, like a washing
Unit 6, The mother of invention Exercise C
Listen to Part 2 of the podcast. Logan is interviewing Celia. What is Celia’s invention?
Logan: This episode is all about ice cream! So I hope you like it. Why ice cream? Because I’m talking to Celia, a student from Hadfield College of Engineering. She has an idea for a new way of making ice cream and … well, lots of other things. Hi, Celia. Thank you for talking to
inventit.com.
Celia: Thanks for having me! Logan: Now, I see you have brought a drawing of your invention. Tell me about it.
Celia: Well, as you said, it makes ice cream. In fact, it makes anything cold, very quickly!
Logan: So it’s like a microwave oven, but it doesn’t heat things up. It cools them down?
Celia: Exactly. It’s a high-speed freezer. Logan: So, do people want your invention? Celia: Well, all my friends love ice cream, but it takes ages to set in a freezer. This is the answer. And it can cool down other things, like water, very quickly. I’m really excited about it!
Logan: Right. And does your invention exist already? Celia: No! … Well, I mean, no, I’m sure it doesn’t. You can’t buy one in the shops.
Logan: But, did you check? Celia: How can I check?

Listen to Part 3. Complete the notes. Write definitions of new words on the notes.
Logan: OK, Celia’s invention sounds good. But let’s link her idea to some basic principles of invention. First, you must check your market. Celia – is there a market for your invention?
Celia: Absolutely. All my friends love ice cream – but they don’t want to wait three hours!

machine or a fridge. I hope I can help her. Celia and I will look at the principles or the most important points of inventing, for example, we’ll see the value of a prototype – you know, an example of your invention; a model to show people, so you can say, ‘Look. It works like this.’
Next week, I’ll talk to Celia about making money from her invention. She must make sure there is a market for the invention. A market is a group of customers. Do people want her invention? The famous inventor, Thomas Edison said, ‘I have learnt one thing. Invent things that people want.’
