Good Morning! Shoot-Around Identify the Dependent and Independent Variables. If skin cancer is related to ultraviolet light, then people with a high exposure to UV light will have a higher frequency of skin cancer. If leaf color change is related to temperature, then exposing plants to low temperatures will result in changes in leaf color. If the thickness of annual growth rings in trees is related to annual rainfall, then examining wood samples will reveal correlations in the growth rings to the historical records for rainfall in its environment.

Measurements: The Metric Scale Mr. Ramsey

Agenda Guided Walkthrough – The Metric Scale 8:55am Visual Walkthrough – Example Problem 9:05am Practice – Problems on dry erase boards 9:15am Scrimmage – Lab activity 9:35am Final Stretch 10:05am

Standard Units of Metric System Length – Meter Mass – Gram Volume (liquid) – Liter Volume (solid) – cm3 1 mL = 1 cm3 Temperature – °C

Metric Prefixes Kilo – 1,000 (103) Deci – 0.1 (10-1) Centi – 0.01 (10-2) Milli – 0.001 (10-3) Micro – 0.000001 (10-6) Nano – 0.000000001 (10-9)

Mini Lab This lab is pretty text heavy. It may seem daunting to read it all, BUT much of the information is valuable to know going forward! When finished, turn the lab into the tray up front for me to check.
