Paper airplane challenge

You have designed 2 different planes - one made for distance, one for flight time.  

Your blog post needs to include:

2 pictures - one of each of your planes - label which plane it is (distance or time) and label the 4 forces that are acting on the plane.

Your results - longest distance & flight time.

Old Assignment - Chemical Safety!

This is an old assignment that I am just posting the questions for - we did this in the first week of the semester... However, there are LOTS of you who have not completed it!

Chemical research – Lab Safety

Choose one of the following chemicals and research these questions:

·      What is it used for?

·      Why is it dangerous?

·      What are some precautions for it’s use?

·      Find it’s MSDS label  / WHIMS symbols

 CHEMICALS:

1. Metallic potassium

2. Metallic sodium

3. White phosphorus

4. Carbon tetrachloride

5. Chloroform

6. Mercury

7. Picric acid

8. Asbestos

9. Carbon disulfide

10. Ethyl ether

11. Potassium Chlorate

12. Hydrofluoric acid

It's Interm Report Time!

Complete this reflection on your progress so far in Science & Tech 11.  This will be your interm report to share with your parents:

Work Habits:  Attendance - how many classes have you missed?  Why?  Do you come to class on time?  Do you come to class prepared?  Do you make good use of your class time?   Are you following the safety rules in the lab?

Assignment completion:  How many assignments have you completed?  What assignments are you missing?  Why?  Have you included your blog assignments in your totals?
What has been the most challenging assignment so far?  Why?

Assignment quality:  Are you showing your learning in your assignments?  Are you completing them to the best of your ability?
What assignment/post are you most proud of so far in this course?  Why?

Plan for success:  In class, I sat and talked with each of you about why you are in this course & what has kept you from being successful in Science in the past.  I would like you to think about whether you are following the same pattern in this class, and write about at least 3 specific things you need to do to be successful in Science & Tech this year.


Based on your reflection/work/progress so far in Science and Tech, provide a work habit of
Good / Satisfactory / Needs Improvement.

Unit 2: Transportation

Transportation is a technology that is ever-changing... What will the future hold?
A big part of society has been shaped by the available transportation - making the world more connected, providing the means to move goods, and creating cities & suburbs.

In a group of 4, you will be researching, comparing and evaluating different methods of travel to a destination of your choice (starting in Surrey to anywhere outside of BC in North America).  Each person will choose ONE of the following in your group - car, train, bus, or plane.  You will compare the mode of transportation for each of the following criteria:

Travel Time
Cost per person
Convenience
Environmental Impact
???

Each person will be "selling" their method of travel, posting their information on their blog (as a brochure, with information and pictures).

Chemistry Unit Project

Chemistry Unit Project – Science & Technology 11 UPDATED

You will be required to show your knowledge of the following information by creating a video, using pictures and props (or using the SHOW ME app on the iPads).  Your videos will need to be uploaded to YouTube and posted on your blog – you can use your phones or the iPads to create your videos.  We are completing this project instead of writing a unit test – please do your best to show your learning in science & tech so far this semester!  It is due at the end of class on Friday - we have 3 class blocks to complete the assignment and upload your videos.

IF YOU ARE USING THE SHOWME APP - MAKE AN ACCOUNT AND FIND THE URL OF THE PROJECTS THAT YOU ARE CREATING (GO TO SHARE VIA TWITTER)... POST THE URL TO YOUR BLOG.

 Knowledge – Safety

• ·      WHMIS symbols and categories

• ·      Describe / demonstrate 5 safe procedures to follow in the lab.

Household Chemicals

THIS PART IS NOT NECESSARY - AS LONG AS YOUR HOUSEHOLD CHEMICAL RESEARCH IS POSTED TO YOUR BLOG.

• characteristics of hazardous chemicals found in the household (your research)

• environmental issues related to the use of some common household chemicals

• methods of safely disposing of household chemicals (your research)

Acids & Bases

 Compare and contrast the properties of acids and bases & provide examples.

·      Describe how red/blue litmus paper works and how pH paper works.

·      Describe how we made a cabbage juice indicator and how it worked.

·      What is neutralization & how did we demonstrate a neutralization reaction in the lab?

·      Compare and contrast acid rain and ocean acidification.  How are each formed and what are some problems associated with each process?

Ocean Acidification

After watching the video and reading the article, complete the following questions about Ocean Acidification either on paper or on your blog.

1.  What is ocean acidification?
2.  What human activities have caused this problem?
3.  How much has the acidity of the ocean changed?
4.  How does the increased acidity affect animals in the ocean?
5.  How are pink salmon affected?
6.  How are coral reefs affected?
7.  How might ocean acidification affect you?
8.  What can you do to decrease CO2 emissions?
