Grade 7: Some Chapter 3 Definitions for Review

Recovery: A return to a normal state of health

Replanting: To plant (something) again or in a new place

Financial Benefit: to receive a monetary (money) gain; e.g., receiving money from an activity

Grade 6 Canadarm3 Development Project - Due Tuesday December 4th

Canadarm3 Development Project

Your team is in charge of developing a Canadarm3 which will be used on Mars during the terraforming process. Since there are many hazards on Mars, Canadarm3 will need to be able to allow the astronauts to do work safely from within their Mars base. This means the arm has to be quite long.

The Canadian Space Agency (CSA) has asked your team to develop a prototype for this arm. You will be allowed to use a variety of materials; however you must follow the criteria below to be successful:

1. Your prototype must be able to pick up a cup of water and pour it into a bowl 1 metre from the starting point
2. Points will be lost if any or all of the water is spilled
3. The astronomer must always be at least 1 metre away from the cup of water at all times
4. Your prototype must successfully complete the same task twice out of 3 times to be successful

Follow the steps below as you are developing your prototype:

1. Review the material available
2. Brainstorm design options with your team
3. Create a design
4. Build your prototype
5. Test your prototype

You will be writing a follow-up response based on your experience building your prototype.

Follow-up Response

Think about the brainstorming, design, building  and testing process you worked through during this project.

1. Which of the 4 steps listed proved to be the most challenging for you? Explain.
2. Was your group's Canadarm successful in completing the challenge? After seeing your Canadarm in action, what would you to to improve your design?
3. How might your experience in building the Canadarm3 been similar to the experiences of engineers designing technology to be used in space?

Response Success Criteria

Grade 7 Ecological Footprint Assignment

My Ecological Footprint

Your personal ecological footprint is how much land and resources it takes to maintain your lifestyle. For example; how much area of the planet you need to produce the resources you consume and to contain the waste you throw out. The less land and resources you use, the better it is for ecosystems.

In this activity, you will use an online ecological footprint calculator to determine how much land and resources you are using to maintain your personal lifestyle. The goal of this activity is to find ways to act more sustainably to help reduce your ecological footprint. In other words; how can you change your actions to help make ecosystems healthier?

Begin by reading about ecological footprints by following the link below:

http://www.footprintnetwork.org/en/index.php/GFN/page/basics_introduction/

The Task

PART A

1. Follow the link below to complete your ecological footprint

http://www.footprintnetwork.org/en/index.php/GFN/page/calculators

2. Select “Calgary” from the virtual map; unfortunately “Toronto” cannot be selected

3. Select “Kids Version”

4. Select “Detailed Version”

5. Build your “avatar” to represent you during the game

6. Answer the questions in the quiz as accurately as possible

7. Read through your results and print a copy to submit with this assignment.

PART B

Write a ONE PAGE response based on the results of your ecological footprint calculation. Your response should answer the following question:

What actions can you take to help reduce your ecological footprint and live in a more sustainable way?

Begin your research by reviewing sections 3.2 and 3.3 (pages 68-81) in your Science textbook.

The following links may also help guide your response.

Please review the success criteria below to help you write your response.

Response Success Criteria

Criteria	Details
Organization and communication	No more and no less than one page in length Written in 12 point font ONLY Written in an easy to read font Text is not bolded Written in proper paragraph form There is no extra space between paragraphs
Content	A minimum of five different strategies to reduce an ecological footprint are included Research into the sustainable strategies is evident Each strategy is clearly explained how it will reduce an ecological footprint A copy of the printed results of the ecological footprint online activity is included
Thinking	The strategies outlined in the response demonstrate a strong understanding of how to act more sustainably
Application	The results of the student’s ecological footprint have been used to guide the response Researched strategies have been described in the response
