Every 10 mph that the turbine spins lights up another light bulb. There is a direct correlation between turbine speed and energy produced. 1) Use the slider to change the windspeed. What is the relationship between windspeed and energy? 2) What happens when you lower the wind speed? This app doesn't work. Can you fix the bulbs? Purpose: To explore a simulation and use if else statements to choose which blocks to run. To keep track of wind speed by using a variable.
