Also know why science course include labs in general. 1. Know safe techniques for the laboratory, and locate lab safety equipment. 2. Apply the rules of metric system unit conversion to express measurements. I will give you a table similar o the table on page 10. 3. Recognize that all measurements have the possibility of error. 4. Identify and categorize error as systematic or random, explain the difference between accuracy and precision.  Which is more precise for measuring, a cylinder or a beaker 5. Be able to obtain measurements for length, weight, volume and temperature.  Review the proper way to measure volume in a cylinder, length of a long bone, weight and volume of a cube (by displacement and by measurement). Lab 2: Purpose?

1. Label the parts of a compound light microscope.
2. Know the proper way to carry a microscope.
3. Describe how to go about focusing on a specimen using a light microscope. 4. Focus an image on a prepared slide and describe in detail your observations. 5. Describe how to...
