INTRODUCTIONYou have a problem. The company you founded three years ago, has not produced a new product since opening its doors and by now everyone has your products, so you are not selling anything. You need to create a great new product, something that will have people lining up in the shops. You need a product that will make cash registers ring and you need to keep it simple... But, there's just one small problem - you know absolutely nothing about simple machines. So, before you design your product, you need to learn something about simple machines. Remember a machine has to be useful, it can be completely original or it can improve another machine.

LET’S BECOME GREAT INVENTORS

PROCESS• You can do this work on your own or in pairs. REMEMBER: before deciding to do it in pairs you must talk to your parents to see if it’s possible or not.

• The work can be done in a Power Point, Word Document, poster or book.

SUGGESTION : I will do it in a paper or poster, because you have to draw your machine.

• You must read everything carefully and do the work without your parents’ help.

• Whatever you need…ASK ME!!! By e-mail, on the blog, in class…
