My story Once upon a time there were Laura and Tereza and during holidays they were in a Cottage. They wanted to live a healthy lifestyle so that´s why they wanted to do a healthy diet. And they wanted to weight every food to know how much they ate and so on. Because in the cottage there was not a Kitchen Scale they had to buy only food that was already weighted from the shop. One day Tereza said to Laura: „Laura, I don´t like eating only the food already weighted from the shop. I want to try other food too. “ „Yeah, you are right“ said Laura. I know one machine that can help us to weight food by ourselves. It is a simple machine called lever. We can compare it with already weighten food. So they followed the design cycle to create the solution.

Strands Strand 1 - Laura we need a simple machine to help us Strand 9 – Ok Laura, now we have our drawing finish, we can to solve the problem we are facing. construct a logical plan to follow the order to make lever. Strand 2 - Yes, you are right Tereza. We need to Strand 10 – Tereza, I think we should take pictures of our steps research about the machine. Strand 3 – And also we need to analyse some levers before we start making one for ourselves. Strand 4 - Ok Tereza, I think we can make a design brief for our lever. Strand 5 – Ok Laura, now we have our design brief so we can make a design specification for it. Strand 6 – Laura, I have a design idea, oh great I have one too. Strand 7 – Ok Tereza, now we have to choose one design idea that we are going to work on. I think that your design idea looks good for solving our problem. Strand 8 – Now we have a design idea for it so lets make a planning drawing for our lever. to demonstrate our technical skills, in case anyone wants to look at it and do a similar lever. Strand 11 – Laura, we are almost finish with our lever. Yeah you are right, Tereza, but we changed some things, so let us make a note of it. Strand 12 – Ok, you are right, we should do that. Strand 13 – Tereza, we should test our solution by putting different things on the lever. On one side we should put already weighted food and on the other not weighted food. We should do many trials that we know it is reliable. Strand 14 – Yeah, it works! Strand 15 – But you know, next time we could improve the fulcrum of our lever. Strand 16 – Yes, you are right, Laura, it would be more stable.

Laura we need a simple machine to help us to solve the problem we are facing. ? Strand 1 – Explain and justify the need

Yes, you are right Tereza. We need to research about the machine. Strand 2 – Identify and prioritise the research

And also we need to analyse some levers before we start making one for ourselves. Strand 3 – Analyse existing products

Strand 4 – Develop a design brief Ok Tereza, I think we can make a design brief for our lever.

Ok Laura, now we have our design brief so we can make a design specification for it. Strand 5 – Develop a design specification

Strand 6 – Develop design ideas Laura, I have a design idea. Oh great I have one too.

Ok Tereza, now we have to choose one design idea that we are going to work on. I think that your design idea looks good for solving our problem. Strand 7 – Present the chosen design

Now we have a design idea for it so lets make a planning drawing for our lever. Strand 8 – Develop a planning drawings/diagrams

Ok Laura, now we have our drawing finish, we can construct a logical plan to follow the order to make lever. Strand 9 – Construct a logical plan

Tereza, I think we should take pictures of our steps to demonstrate our technical skills, in case anyone wants to look at it and do a similar lever. Strand 10 – Demonstrate technical skills

Strand 11 – Follow the plan to create the solution Laura, we are almost finish with our lever. Yeah you are right, Tereza, but we changed some things, so let us make a note of it.

Strand 12 – Justify changes made to the design Ok, you are right, we should do that.

Tereza, we should test our solution by putting different things on the lever. On one side we should put already weighted food and on the other not weighted food. We should do many trials that we know it is reliable. Strand 13 – Design testing methods
