Scratch

Scratch is a visual programming language that is perfect for anyone learning to code. Scratch creates programs by connecting blocks of code by using a drag-and-drop GUI so users do not have to type programming languages. Users can simply select colored blocks of code that, when joined, create a script or a set of computer instructions that can make objects such as people and animals move and speak. Users can create interactive stories, games, and animations with the click of a button.

Scratch is a free project created by the Lifelong Kindergarten Group at the MIT Media Lab and currently has more than 8 million users. The goal of Scratch is to help young people learn to think creatively, reason systematically, and work collaboratively—essential skills for life in the 21st century.

In a group, visit the Scratch website at http://scratch.mit.edu/. What type of system development methodology is Scratch using? What skills can young people learn from creating Scratch programs?

Scenario You work for a small company that exports artisan chocolate. Although you measure your products in kilograms, you often get orders in both pounds and ounces. You have decided that rather than have to look up conversions all the time, you could use Python code to take inputs to make conversions between the different units of measurement. You will write three blocks of code. The first will convert kilograms to pounds and ounces. The second will convert pounds to kilograms and ounces. The third will convert ounces to kilograms and pounds. The conversions are as follows: 1 kilogram = 35.274 ounces 1 kilogram = 2.20462 pounds 1 pound = 0.453592 kilograms 1 pound = 16 ounces 1 ounce = 0.0283 kilograms 1 ounce = 0.0625 pounds For the purposes of this activity the template for a function has been provided. You have not yet covered functions in the course, but they are a way of reusing code. Like a Python script, a function can have zero or more parameters. In the code window you…
