Science 9

Science Fair Pre-Event Reflection:

Digital Footprint:

  1.  Yes, I was able to add yo my edublog to reflect upon my experiment.
  2. We used discord to talk with each other and present ideas, and we used google docs/sheets to record our data and create the graphs.

Experiment Questions:

  1. Our research question was: What is the most effective angle for propellers used in wind power generation?
  2. We have done research on wind turbines, and we have done some research on conduction this experiment.
  3. Setup: Materials:–          Motor–          Multimeter–          Fan–          Multiple propellers of varying sizes (self-made)

    –          Copper wire

    –          Paper/Pencil (to record data)

    –          Room with closed doors and windows

    –          Cork (preferably thick sheets)

    Procedure:

    1. Organize propellers from biggest angle to smallest angle of.
    2. Put the fan on a table/countertop/any flat surface.
    3. Mount the first propeller onto the motor.
    4. Attach copper wire to motor and multimeter.
    5. Make sure multimeter is measuring the voltage output from the motor and propeller.
    6. Align propeller with fan.
    7. Turn fan on to highest setting. (Or any other setting, however needs to be the same setting for all propellers/tests to keep consistency)
    8. Look at the multimeter and record the output voltage.
  4. We can connect with experts in this field via email, or maybe a phone call if the expert agrees and is willing to talk to us.

Science Fair Post-Event Reflection

Digital Footprint:

  1. Yes, I was able to add to my blog and reflect upon my science fair experiment.
  2. We used discord and google docs in order to collaborate with each other online.

Experiment:

  1. No, we predicted that the best propeller blade angle would be 45 degrees, however our data showed that 30 degrees was the best angle and through further research we confirmed that 30 degrees is the more effective angle.
  2. Yes, everything went according to plan while conducting our research and collecting our data. We followed our procedure, and it worked effectively for us.
  3. We talked to Mrs. Greenwood to borrow a multi-meter and she explained how to use it, overall went well.
  4. We had the assumption that our fan would be strong enough to power the propeller, and when we were collecting our data our assumption proved to be true.
