Introduction - what were you investigating? Prediction - will your design produce enough energy to charge an iPod for an hour in the 10 minutes you have? Conclusion - What did you discover? the two tone red and blue windmill we made in second lesson: maximum current value: 4.2, 7.5, 8.6 then 9 mA on highest wind setting Evaluation - How would you improve your windmill design if you were doing this experiment again? What would you like to ask a power expert about this experiment?

Introduction - what were you investigating? Prediction - will your design produce enough energy to charge an iPod for an hour in the 10 minutes you have? Conclusion - What did you discover? Long arms make it heavy, max current reading is 0 mA this is why scientists test their work Evaluation - How would you improve your windmill design if you were doing this experiment again? What would you like to ask a power expert about this experiment?

Introduction - what were you investigating? a) windmills b) wind mills c) We were investigating how we can power an ipod with mini windmills d) How we could power an iPod Prediction - will your design produce enough energy to charge an iPod for an hour in the 10 minutes you have? a) No b) probably not! Conclusion - What did you discover? a) That can work b) We can't power a ipod for an hour c) We discovered that the smaller and less heavy spin the most d) That our windmill was the best design Evaluation - How would you improve your windmill design if you were doing this experiment again? a) Make it lighter b) make it a bit lighter! c) We don't need too we won anyway d) We would make it smaller What would you like to ask a power expert about this experiment? a) Does it really work? b) Nothing c) What made our design the best? d) What made our design win?

From group's reports: Introduction - what were you investigating? a) b) How much energy you can make using a miniature windmill model Prediction - will your design produce enough energy to charge an iPod for an hour in the 10 minutes you have? a) b) No because we didn't get to finish and it was weak Conclusion - What did you discover? a) b) That you have to work hard to get a good result Evaluation - How would you improve your windmill design if you were doing this experiment again? a) b) Don't work your friends and you will inprove What would you like to ask a power expert about this experiment? a) b) That they did a good job.

Introduction - what were you investigating? a) How to make a fan that produces enough energy to charge a ipod b) Which make fan makes the highest volts and milliamp c) Which home made fan can produce the most energy d) Which designs materials etc. could produce a wind turbine that produces the highest wattage Prediction - will your design produce enough energy to charge an iPod for an hour in the 10 minutes you have? a) No because the shape was bad b) no c) No d) Probably not - our fan produced very little miliampsand voltage as a result this produced very little wattage Conclusion - What did you discover? a) Paper plate work well : ) b) Make the fan simple and easy c) That you need a small fan for the most power d) It is very difficult to make a wind turbine capable of producing enough energy out of paper. Industrial wind turbines are much more capable Evaluation - How would you improve your windmill design if you were doing this experiment again? a) Use a paper plate b) Make it more simple c) make it smaller d) Probably support the fan more and give it a larger surface area What would you like to ask a power expert about this experiment? a) nothing b) an easer whay to do it c) how to make ours the best d) No- I'm not amazingly interested in this field and I really wouldn't want to Click comments below for answers

Taken from group's reports: Introduction - what were you investigating? a) How wind be turned into power b) can our wind terbines can provide enough to power a ipod c) Can our wind terbines can produce enough energy to charge an ipod for an hour Prediction - will your design produce enough energy to charge an iPod for an hour in the 10 minutes you have? a) Yes b) No because our V was 0.0 and our mA was 0.0 because it didn't move c) No because our V was 0.0 and our mA was 0.0 because it didn't move Conclusion - What did you discover? a) We couldn't couldn't create enough energy to power anything b) The closer the fan the faster it is c) The closer the fan the faster it is Evaluation - How would you improve your windmill design if you were doing this experiment again? a) We would add more objects for more wind resistance b) More blades to make more our resistance c) More blades on it to make more our resistance What would you like to ask a power expert about this experiment? a) why ours wouldn't move?!
