Science 10- Cells Unit - Feb 18-April 6

Starting April 6:
April 6 is the projected start date for all your classes to resume learning in some form.  I hope that you have followed the recommendations for the work in Science and have got to the point where you have done some review on our Cells Package.  If you have completed that, then next week (April 6-9) will be a chance to assess your understanding before we move on to the "Systems" section of biology.  If you haven't done the suggested review, then see my previous post detailing the work.

My tentative general plan to proceed in Science as of April 6:
1.  We will move at a slower pace due  to the additional challenge of learning in an on-line format.
2.  Check my website: schieck-chem.blogspot.com at the beginning of each week to see what you need to do in Science that week.
2.  At the beginning of the week I will try to post a little assessment quiz that you can try and mark yourself (for feedback and practice) 
3.  Then we will cover 1-2 topics in the week.  I will experiment with a variety of formats for delivery and I will give you some practice questions.
4.  At the end of the week if there are questions (either conceptual or homework question you didn't understand) please e-mail me by Friday and I will try and address them in some format at the beginning of the following week.
5.  We are both figuring this out as we go.  I appreciate your questions and feedback (What learning formats work and which don't?)


Some recommendations to Prepare for April 6-Get Organized:
1.  Gather your binders/folders/textbooks and organize them.  File away old notes, evaluations etc...
2.  You can set your own schedule!  Pick 4 classes to work on a day and schedule them into your agenda book.  Work on classes every other day.
3.  As you receive instructions from your various teachers, add them to one master "to-do list",  crossing them off as you accomplish each one.
4.  Make sure you have you have each teacher's website/googleclass readily accessible.
5. Don't hesitate to e-mail your teachers.  We need your feedback.

I know these conditions are not ideal.  Do your best.  That's all you can do.  Reach out to me if there is anything I can help with.

March 23-April 6:
KEEPING UP WITH SCIENCE AND LEARNING DURING THIS EXTENDED BREAK:
You've had lots of time to sleep and binge on games and movies.  Its time to restart your brain from leisure mode.  During these two weeks I would like you to do science, to maintain your progress in science.  We don't know what the future holds, but whatever work/learning you do at home now will help to build your brain/thinking (this strengthens along with everything else), and will help to get you ready for grade 11 next year (in a worst case scenario).
In the next couple of week I'd like you to do a few things over the course of the upcoming week:
a)  review cell parts and functions by watching this video:   
b)  review diffusion by watching this video:
c)review mitosis by watching this video:
d)  review cancer by watching this video:

Lastly, after watching each video, spend a few minutes reviewing your notes on the topic.

Rest assured that the grade 10 science teachers do NOT intend to cram the remaining course in compressed time frame (when and if we return to class).  We will select the most important topics to cover for the remainder of the school year.  If you have any questions, I will be checking my e-mail periodically during the school day.

Why don't you start the first video now?
