Grade 8 - Here is what you need to know for the test:
- What is a fluid (definition and examples)?
- Characteristics of fluids
- Different types of flow (laminar, turbulent)
- How particle theory explains fluid behaviour
- How to measure flow rate
- What is viscosity, cohesion & adhesion?
- What is mass, volume and weight?
- What is density and buoyancy?
- How density and buoyancy work together to make things float/sink
- Archimedes principle
- The impact of different types of water (salt vs. freshwater & hot vs. cold water) and use the particle theory to explain this
- Positive, negative and neutral buoyancy
Science:
Grade 8 - Monday you are handing in your questions that go along with your Penny Boat Challenge (even the class that doesn't have Science on Monday (8B) I will be coming to your class to collect!). Below are the questions that you need to answer and I have also included each groups results and pictures of everyones boats for use when answering the questions. On Monday, I will also give you a handout of what you will be expected to know the for the test on Thursday, April 3, 2014. It will be on the first two sections of this unit: 1) Movement of fluids (characteristics of fluids, flow rate, adhesion, cohesion, types of flow, viscosity) and 2) Density and Buoyancy.
1. Make a brief sketch of your boat and show your volume calculation.
2. Explain how you used your knowledge of density and buoyancy in designing your boat
3. Examine the class results. Is there a relationship between volume and the amount of pennies a boat could hold? Explain.
4. Where the boat(s) that held the most mass similar to real boats/ships? If yes, explain how they were similar. If no, explain why the penny boat was more effective than the traditional boats.
5. One of your friends claimed,” The more the boat sinks, the more water gets displaced and the more buoyancy there is. Therefore, shouldn’t it be easier to float (the more the boat sinks) because buoyancy is getting stronger?” How would you respond to this?

Complete photo essays are due MONDAY!! You need to be handing in your photo essay along with a write up that explains each of the pictures and how they link to the themes seen in the story of Angelique. Your write up needs to include an introduction, conclusion and a paragraph for each picture in the photo essay. Each paragraph needs to answer the following questions regarding the picture: 1) What theme from the story is your picture highlighting and how (includes explanation for why this is a theme in the story) and 2) What techniques were used to make your picture effectively capture the theme (see photography techniques below). Assignments will be handed in at the beginning of language Monday, March 31, 2014.
Language:
Photo Essays - You are creating a photo essay that tells the story of Angelique through pictures. You are creating pictures that depict themes represented in the story and tells us what happened to her and highlights the reasons for learning about her story.

- pictures need to represent the full story (multiple themes), message is clear
- 6-8 pictures
Language:
1) Due tomorrow: analyze another groups picture under the thread "CAPTIVATING PHOTOGRAPHS". Answer the questions: What theme did they choose/capture? What techniques did they use effectively? What techniques could they have used better?
2) Due Monday, March 17th: You need to have your own picture posted to the thread "INDIVIDUAL PICTURES" on voicethread and provide an analysis stating what theme/emotion you chose to capture and how you used 2-3 techniques effectively to communicate this theme/emotion.
Math:
Math test tomorrow on surface area and volume of 3D shapes (rectangular prisms/cubes).
Language:
You have been asked to go online and find a picture that captures the theme of "HOPE". You need to make sure you are finding a picture that uses the photography techniques discussed in class to effectively communicate this theme to the audience. Please post the picture to drop box, under Hope Pictures and bring in a write up that goes with the picture describing why you chose the picture and how the techniques are used to demonstrate the theme through photography. Here are the techniques you came up with as ways photographers effectively get their message across.
Photography Techniques:
- Camera Angles - high (above, birds eye view), low (below)
- zoom (close-up, medium shot, wide/far away shot)
- includes 1 person, couple or small group, large group
- background/foreground
- focus/focal point
- still or action shot
