Brainstorming:To build and windmill, we would have to brainstorm to get an ideas of how \we want our windmill and an idea of how the windmill will work. This is basically what brainstorming is. To think ahead to build the project. Fatima: Research: based on our brainstorming we started researching ideas but that wasn't enough we watched videos took notes on them and then we researched what affects the blades the number the length the material Trey: Top Three Ideas: Next we took three ideas that we had in mind for our. Our top three include using a CD as the blades, our 2nd is using a coffee cup, we would cut it into four pieces and used them as blades. Our final idea was making a paper pinwheel and the bass would be a milk carton. Christian: Decision Matrix: For the decision matrix we came up with an idea and then we split those ideas into 3 categories: cost,creativity and time. So as you can idea#1 go the highest total Kathy: Top Idea: our top ideas was the windmill i came up with which is a windmill from back then in 1990s and it's a milk carton with a blade made out wood. Fatima: Building: Building wasn't as fun as we thought it would be. We kept having to change our design. Our painting didn't go so well either. Our first coat chipped off. some of our teammates didn't come to school Well we had fun but not as much as other projects Trey: Revisions: For revisions we first decided to color the whole carton grey, and decorate it to look like a windmill used by farmers, and then we needed to fix the motor itself, it wouldn’t spin because of cork holding it in place was to big for hole it was placed in so we swapped the motor and the cork. Christian: Conservation of energy:says that energy can’t be created nor destroyed Kathy: How the Windmill Works:making
Fatima: Energy Transformations:the energy transformations were the kinetic energy of the wind transferred to the mechanical energy of the turbine then the the motor transferred this energy into electricity Trey: Kinetic Energy: Kinetic energy is the movement of the object, the windmill is made to collect wind and allow it to push the paper pocket so that it can move, but this also depends on the speed velocity of the wind. Christian: Potential Energy: Is going to the blades from the wind and when the blades are spinning the energy is being released from the blades. Units: mass*gravitity*height |
