Tomorrow you will be asked to let Miss Hodgins know which one of the following meals you would like to order at Briskets Restaurant in Montreal:

1. Briskets’ famous smoked meat sandwich served with fries and coleslaw

2. Vegetarian Couscous

3. Spaghetti with tomato sauce

*** all meals served with a soft drink and dessert

Systems in Action

The smooth functioning of society depends on a great number and variety of systems. The needs of society can influence the evolution of established systems or demand the introduction of new ones. Your group will be responsible for researching and becoming experts on ONE of the topics below that relate to our science unit on Systems. Your group will prepare a lesson for the class that may include detailed explanations, visuals, examples to work through or a short video. Your group may choose to provide a handout and/or worksheet for their classmates to work through during your presentation as well. What you prepare for your classmates will depend on your topic.

Topics:

  • automation  (impacts of automating systems)
  • force
  • friction
  • work and energy
  • how to calculate work
  • functions of machines (increasing force, increasing distance, changing direction)
  • input and output forces
  • how to calculate mechanical advantage
  • efficiency

Simple machines (teach what they are, show how they work, give examples)

  • levers
  • pulleys
  • wheel and axle
  • inclined planes
  • the screw
  • the wedge

Review of concepts relating to fluids and properties of fluids:

chapter 7

chapter 8

For your fluids test make sure to review the following:

– what are fluids?

– the particle theory

– how particles act in the 3 states of matter

– the properties of fluids: density, viscosity, buoyancy, pressure, compression

– how temperature effects these properties

– how to calculate density

Hey everyone,

I just wanted to pass along the definition and activity sheets for the first six Probability lessons. If there are any lessons that you are feeling a little unsure about, please come speak with me in class or at break and I can help bring you up to speed!

Lesson Plan #1 – Experimental and Theoretical Probability

Lesson Plan #2 – Range of Probability

Lesson Plan #3 – Tree Diagrams and Organized Lists

Lesson Plan #4 – Odds For and Against

Lesson Plan #5 – Understanding Simulations

Lesson Plan #6 – Probability Models

Great work, everybody!

Hey guys,

I just wanted to pass along the link for the website that we used today in class! I would highly recommend reading through it, as it does a very good job of explaining the process of calculating theoretical probability in these complicated situations.

I hope this helps! Please come in to speak with me if you have questions about any of this or if you are feeling a bit confused.

Attached is a flyer for Prom Project Hamilton for those that are in need of a dress for graduation.

Prom Project Hamilton is a one-day event at two locations, created by the HWDSB Foundation to support students by offering formal wear for their proms, graduations, formals or other special events. All new and used items are free of charge and have been donated by private and business communities.
