execute: Our task is to charge different material of rods with some fabric and find out the strongest pair of conductors. our testing is demonstrated in the chart above. I believe that out information was well plotted together. These results will definitely help us with our next test, trying to make a motar to spin a ruler around on a vertical axis.

 

 

Examine 

During these past two classes in Science Honours 9, we have been testing static electricity using many different types of materials.  We used a Ring stand to drape a pith ball to represent a neutralized charge. We first tested using lucite by rubbing silk all over it and placed the end of it near the piff. The electrons transferred on to the piff and attracted the piff suddenly was very attracted to the Lucite.  to realize why this is happening we first thought about why this is happening. For example when we rubbed the spoon with the animal fur, the electrons from the animal fur transferred onto the spoon. when we placed the spoon near the neutrally charged piff the spoon was instantly joined to the piff as the electron was attracting, but then as soon as the electrons had switched to the  piff  and it seemed impossible to  places these two objects together because they now had the same charge, as the saying goes ‘opposites attract’ and in this case this was very well shown in the beginning and as soon as they had become the same charge they quickly repelled each other.  So with all the testing that we have done, I can now conclude that when the test subject and the piff ball are attracted to each other that means that they have opposite charges, but when they repel each other that means that they have a neutralized charge.

 

 

 

Group contract;

 

  1. What skills and strengths does each of the group members have to help you accomplish this project?
  2.  Emily- a Strong leader, keeps everyone in tack, efficient
  3. Maddy- Dedicated, good time management, artistic
  4. Claire- Creative, collaboration, keeps people together
  5. Megan- Thinks outside of the box, sociable, confident in public speaking
  6. How are you going to divide up the workload? What roles and responsibilities are assigned to each person?
  •  Maddy – Recorder
  • Megan – Racer
  • Emily – Racer
  • Claire – Timer
  1. What rules do you want to have regarding your collaboration? (e.g. equal workload, deadlines met etc.
  • Everyone will keep inside the timeline
  • Everyone will get an equal workload
  • Listen to others
  • Encourage others ideas
  1. What will you do if these rules are not being followed?

We will talk as a group to make sure everyone is on track, start again with fresh ideas.

  1. Do you have any questions regarding the task that needs to be answered? Do you understand the requirements of the project?

the project seems quite clear.

  1. What goals for the task do you have for the group?

We hope to get everything done on time, completed to the best of our abilities, and hopefully exceed the expectations or do generally well on our evaluation marks.

  1. What will the final outcome or product look like and what information is needed to accomplish the task?

We take turns recording the information while two people are testing two different rod + material combinations at once. Our other person neutralizes the pith ball so one of the two ‘chargers’ can test their charge. It worked out pretty well and quite efficient.

  1. If you were to break down the task into manageable pieces, what would the timeline look like, considering when the project is due.

Testing will occur March 7th and job would be completed as follows;

  •  Maddy – Recorder
  • Megan – Racer
  • Emily – Racer
  • Claire – Timer

All information and recorded data will be formatted and finished by the end of the day.

Everything will be completed and handed in, whether that be digitally or on paper  on March 7th at 3 pm
