The Conn: Tuesday, February 21st 2017

Today's Quote:

'Most of us live in a world where more and more places and things are signposted, labeled, and officially ‘interpreted’. There is something about all this that is turning the reality of things into virtual reality. It is the reason why walking, cycling and swimming will always be subversive activities. They allow us to regain a sense of what is old and wild in these islands, by getting off the beaten track and breaking free of the official version of things.
~ Roger Deakin from 'Waterlog'

Recap:

6th graders Almost finished notes over tsunamis and volcanoes ad we will do that tomorrow

7th grade finished human reproduction with the exception of the male timeline which we will do today.

8th graders tackled a free fall problem and then I realized I need to go back and explain this in more detail.

NOTE: egg lander drops will be Tuesday and Wednesday this week.

Brain Bender:

Dee Septor, the famous magician, recently claimed that he had been to New York City performing a feat that no one else had accomplished. He boasted that he had walked on his hands for a mile and a half down a typical cement sidewalk before he lost his balance and fell. What is wrong with Dee Septor's claim?

Agenda:

Makeup work and parent phone calls.

Today and Tuesday I will be offering a one-time chance to get caught up. All grades are in the grade book. We will also be notifying parents BY PHONE.

1. Check your portal (You can only make up work in this nine weeks)

2. For ANY work you are missing you will be able to read that chapter in the textbook, do ALL the section review questions, and submit your notes and questions by Friday of this week.

3. You will receive a grade no higher than a 70% for this work. (You should have done it when it was due)

4. you MUST put the following as the heading on your paper:

full name, period, title of the unit you are doing, the assignment you are replacing. If this information IS NOT on the paper, you will receive no credit.

5. If you are missing IXL work (you should have 10 assignments done at the end of this week with an 80% or higher) you can make them up by Friday for no higher than 70% (you should have done them when they were due.)

6. If you missed a lab, you will have to find a corresponding chapter in the book and do it for work. (It cannot be the same as one of the other assignments you have done)

EXAMPLE: You didn't turn in the notes over the nervous system. You find the chapter on the nervous system and READ it, taking notes. Do the section review questions AS YOU READ. Do the chapter review at the end. Turn it all in by Friday with the heading information above.

(This should be written in your planner every day)

Wil-E-Coyote drops a bowling ball off a cliff to try to catch the Roadrunner. The cliff is 132m high.

A. How long does it take the ball to fall to the ground? _________________

B. What is its impact velocity? _________________

C. How far does it fall in the first 3.0 seconds? _________________

D. How fast is it going at the end of 3.0 seconds? _________________

Egg Lander Pricing list: As we discussed in class, businesses must balance their choice in production materials with the goal of making a profit. Everyone wants to use the BEST materials, but everyone ALSO wants to make a profit. What happens is, you have to make trade-offs. Choosing alternative materials allows you to ensure quality and safety while still maintaining a healthy profit margin. This is a RISK you take in business. We are going to apply an element of this risk to your egg landers.

The fine print:

You may work individually or as partners.
You must form a corporate name.
You will purchase ALL materials for your egg lander vehicle. (I may have some of them in the class, but I cannot supply everyone, everything) I will supply one "eggstronaut" to each individual or partner group.
You must use the following "risk" points guide when purchasing materials:
If you manage to successfully land your vehicle with your eggstronaut intact and within the target zone, you will get all of your RISK grade points back.
As payment, you will also receive one "get out of test free" card, usable on any regular class test or quiz.
The landing zone: you must land within the target zone. Two grade points will be subtracted from your overall total for every .5 meters outside the target zone. In the real world, precision and accuracy are extremely important and costly in both time and money if they are not part of the constraints of any project.
