-Density

Learning Targets

• • Today we will learn about lab safety and the scientific method.

  • Today we will learn to identify common equipment found in the laboratory and make qualitative and quantitative observations about them.

  • Today we will learn to use proper lab equipment and techniques for accuracy and precision.

  • Today we will learn about significant figures(uncertainty) in laboratory measurements.

  • Today we will learn about representing numerical values in scientific notation.

  • Today we will learn about converting units of measurement.

  • Today we will learn about density.

Essential Questions:

• 1. How can observations be classified?

  2. How can the uncertainty in quantitative observations be expressed?

  3. How does accuracy and precision play a role in making valid measurements?

  4. How can different materials be identified in the lab?
