Google Hangout Tomorrow March 31 2pm

Hello all,

I hope you are well. Tomorrow I will be available at 2pm on google hangouts (meet) to video conference with you to answer general questions or ones about content, energy audit, etc. Use the link below to join. I hope to see some of you tomorrow.

See classroom for link.

Thanks!

Return From March Break

Hello all,

I hope that everyone is healthy and that you are following the recommendations of our health professionals. It is very important for us all to do our part. The ministry of education has created a new website to supplement your learning over the current 2 week shutdown. You can access it HERE. There are currently no resources for grade 11 physics, however that may change in the near future. It is likely worth your while to continue with the work we have been doing before the march break anyway. You can be working on:

• Energy Audit Assignment
• Acceleration of a Falling Object Lab (for those of you who have not yet submitted it in classroom)
• Motion graphs - kinematics (see the BLOG for details)
• Phet simulations!!! they are awesome if you are looking for some physics fun (I will reference specific ones as needed)

We have not received more direction beyond the website resources from the school board  at this time but I will keep you all posted as things evolve (and in the event the 2 weeks is extended). In the meantime, please email me or post on the classroom questions that I can help you with so that you are able to make progress in your learning.

HERE is a link to the textbook sections (It is currently not complete, the sections you need now are there and I will work toward having the whole text available soon)

Also the link for our blog again HERE.

Thank you all in this difficult and unprecedented time,

Michel Ray-Zarate

Kinematics - Motion Graphs

Hello all,

Today I would like you to work individually or in small groups on the topic of motion graphs. We have mentioned them briefly but hopefully with the help of the textbook you will be able to improve your understanding and complete some practice. 

Please read through, take notes and try practice problems.

Section 1.4

Have fun!

Energy Audit Project

Hello all,

Here is a copy of the energy audit project in PDF.

For apartment and condo dwellers....

Click HERE and use Figure 9 and 12.

Here are some guidelines for the report writing process.

Reports need to have proper formatting including the following:

1. Title and abstract/introduction (a short intro that provides the rational and content of the report)
2. Headings and subheadings 
3. Clearly listing sources of information and rational for any assumptions/approximation made
4. Lab formatting rules apply (graphs, figures, appendix, calculations, etc.)
5. Attractiveness and professionalism (font size, images, captions/labels, location of text vs. figures, page breaks, colour, etc.)  
6. use equation editor for sample calculations or do by hand. 

Here is a link to a similar report that you may use as a guideline for formatting.

Lab exemplar (grade 10)

This is a lab exemplar from grade 10. Use it as a formatting guide. In terms of content it is fairly representative except for the purpose statement as the grade 11 requirements have increased. See the Physics Handbook for details.
