Go back to your desk and get ready to take the test immediately once class starts Objective: • I can be assessed on important information about Energy Homework • Meet in Computer lab 220 tomorrow Please have on Desk: Your notebook to use on the test. Thursday, December 3rd Entry Task Schedule: • Scratch Grab a paper from the front Objective table. Log onto the computer and onto Scratch. Wait for further instructions. Homework: • Upload project to studio by Monday morning. Energy and Economics Simulation Computer App Session 8 Energy and Economics Simulation Learning Objectives: • I can research information on the web to be used in a simulation. • I will create a simulation that has money in its model. What are some simulation games that use money? • Farmville • SIMS games • Zoo Tycoon • Rollercoaster Tycoon Explain how money is used in these games. Energy and Money Simulation • This is a simple simulation that allows you to build coal plants and wind farms and then you get to see how much energy and carbon dioxide (CO2) they produce. I will demonstrate. Notice that: • Energy is in megawatts, money is in million US dollars, and CO2 is in billion pounds. • Every second, 0.1 years passes. You have 5 years to get as much energy as you can. • Hold your mouse over part of the screen and type “W”. This buys a wind farm and puts it at that location. Your money goes down a little and you start producing energy. You are not producing CO2. • Hold your mouse over part of the screen and type “C”. This buys a coal plant and puts it at that location. Your money goes down a lot and you start producing a lot of energy. You start producing CO2. • As you produce energy, you get more money to spend on wind farms and coal plants. Let’s Analyze the Simulation • Note that the script for the coal plant is very simple: when I start as a clone, go to the mouse pointer. The script for the wind farm is exactly the same. • Where is the model with all the equations? The stage is where the code for the model is! • When the “w” is pressed, a wind farm is created. Here is the code: When “c” is pressed, a coal plant is created. Here is the code: • It’s exactly the same as the wind farm code, except it costs 2 billion dollars (2000 million) to build a coal plant. • The other script • has more equations! • There are also some yellow blocks. These are comments. The computer ignores them, but they are useful to someone looking at the code. They are being used to explain the units on the variables. Your turn: • Go to: https://scratch.mit.edu/projects/50128898/ • Click “see inside” • Click “remix” Add to the simulation • Add a natural gas plant to the simulation. • First, find out how much energy it produces and how much it costs to build (search the web). • Natural gas plants produce about 3.4 million lbs of CO2 for each megawatt generated. • So, if you are using a 625 MW plant, you will generate about 2100 million lbs of CO2 per year. Create a natural gas sprite Now run the program • Does it work? • Save your project with today’s date and your name and share it to the class studio. • Remember to turn off commenting! Friday, December 4th Entry Task Schedule: • Project Story board Be ready to share one thing you found helpful when Objective browsing other scratch • I can create a story board projects. Be ready to explain for my project with scratch how you may do something similar in your project. Homework: • By Monday- Upload at least 1 energy conversion to this studio: https://scratch.mit.edu/studi os/1735845/ 84
