Blogging Etiquette
Acknowledge the author of the blog post.
Let the author know if you agree with him/her and why.
It is also ok to disagree with something, just let the author know why you feel that way.
One word comments are not very useful. Writing just “cool” or “nice” are not very helpful and don’t let the author of the blog post really know what you are thinking.
Always make sure you follow “netiquette”. Think if it is appropriate BEFORE you hit the submit button.
Always be polite. It does not matter if you agree or disagree with what you are reading in a blog. Don’t write anything you would be ashamed of saying to someone’s face. Don’t hurt somebody’s feelings.
Boiling Point and States of Matter Connections and Review Assignment
Boiling Point and States of Matter Connections and Review Assignment
After watching the following video, be ready to interpret your own heating curve graph from your last blog post.
Thanks to MR. Kent’s Chemistry Page, You can find great graphs and explanations (Warning, some parts are beyond the 6th grade level expectations.)
Your Task:
Create a presentation that will be delivered in your next blog post describing all you have learned about the States of Matter and Boiling Point while making connections and reviewing for your upcoming assessment.
Use the Rubric HERE to make sure you have done your very best to show what you now know and understand.
HELPFUL TO THINK ABOUT AND USE AS NEEDED:
 Demonstrations – Vacuum Chamber – marshmallow, boiling water, balloon; Ball and ring (heating it made it not go through the ring); Alcohol and Water – 50 ml + 50 ml ≠ 100 ml
 Videos – Boiling water on Everest; Brain Pop – States of Matter or Matter Changing States; Eureka Videos – Solids or Liquids ; Plasma Video
 Readings: KS3 Bitesize; Chem4Kids Website
 Lab Sheets
 Blog Posts: State Change Graph: Look up what you already have done on your blog!
 Vocabulary words – (see below)
Don’t forget the following when presenting your work:
 Design – is it easy to read and laid out nicely
 Words – not too wordy but enough so that it is understood
 In your own words – don’t copy and paste
 Images/Media – “a picture says a 1000 words!”
 Spelling, grammar, paragraphs and all of your favorite things
Vocabulary:
 Air Pressure
 Boiling Point
 Condensation
 Diffusion
 Evaporation
 Solid
 Liquid
 Gas
 Matter
 Molecule
 Pure Substance

Math Summative Assessment Review for Representing and Converting Portions, Fraction Multiplication, and Integer Addition and Representation on a Number Line
Here are practice problems and answers(at the end of the post) for our upcoming assessment that is scheduled for December 10th. Please take your time to go through the different sections and practice leading up to the assessment and NOT just the night before. If you have any questions, make sure to ask me during class, at break, at lunch or at homework club time on Mondays.

 510. PARTS OF PARTS: Part One
 Representing a portion of another portion can be thought of as finding a “part of a part.” For each of the parts of parts described below, work with your team to figure out what part of the whole is described. For each problem, show at least one picture or diagram that helps you make sense of the problem.
