Sept. 10 Class - Scientific Notation and Unit Conversions

Learning Goals:

• Understand Scientific Notation
• Understand Unit Conversions

Success Criterion:

• You can convert between scientific notation and standard notation.
• You can convert from one unit to another.

I started by giving some notes on what an MSDS is (Material Safety Data Sheet).  There is one sheet for each chemical in a lab or workplace.  The sheet contains important information such as how to handle the chemical and how it might react.

Next we looked at this flash website: http://htwins.net/scale2/

The site is a great way of showing how large and small our universe can be.  Science covers topics on all scales from the extremely small to the extremely large.  Scientific notation is away of writing down these really large or really small numbers in a short form.

Handouts:

• Scientific Notation
• Scientific Notation Solutions
• Unit Conversions

We spent some time discussing how to write in scientific notation and how to use unit conversions.  We also worked out some examples.

Homework:

• Complete both sides of the handouts.
• Complete safety poster if not done.
