Get a Charge Out of
Matter
Week 7 - Chapter 3
Highlander Sheet
• Objective/SWBAT:
Determine the central idea of a
unit and use evidence to provide analysis of what it
was about.
• Responsibilities: Finish analysis.
•
Today you will need:
• A blank sheet of paper (to turn in)
• WHOT
• Something to write with
Reading Skills
• What is the article about? Identify the central
idea.
• Why do you think its about that? Support the
central idea with evidence.
• What do you think it means? Be sure that your
analysis tightly connects evidence to the central
idea.
• WHOT QUESTION: Create a question and answer
about the article.
• Objective/SWBAT: Explain why pure water does not conduct electricity but
some solutions do. Charge and electricity are connected concepts that
depend on one another.
Warm up

• Would you swim in a pool of pure H2O during a lightning
storm? Why or Why not, justify your answer scientifically.
• Responsibilities: Vocab:
• Electricity, charge, plus, minus, movement.

What happens here?
•Get a charge out of matter
• Electricity
• a form of energy resulting from the
movement of charged particles (such as
electrons or protons).
• Examples… static, current

What is it about a solution that allows it to conduct electricity?
Explain.
Hint: (a battery has these too)
• Responsibilities: Vocab Quiz Friday.
• WHOT QUESTION (from yesterday):
• There is something else in tap water that makes it
conductive. What are some ideas of what it might
be?

• Objective/SWBAT: Use proper technique to
light and adjust a Bunsen burner. Explore
physical properties of matter
• Warmup: What are some safety precautions
you should take when using a Bunsen
burner?
• Responsibilities:
• Do not catch on fire, get data for lab.

• Objective/SWBAT: Make groups of different
molecules based on physical properties.
• Warmup:
• Olive oil, vinegar, and water
• Label each as polar/nonpolar
• Which 2 liquids would mix?
• Responsibilities:
• Finish lab conclusions, notebook quiz
tomorrow.
Everyday Materials!
• Aspirin
• Corn Starch
• Deicer
• Kosher Salt
• Vitamin C
• Epsom Salt
• Paraffin Wax
• Sugar
We use materials everyday, understanding
these materials helps us make discoveries
and design new products. The more we
understand about the “material world” the
greater the opportunity for success!
