  1. Field Investigations “Using his senses man explores the world around him and calls the adventure, science!” Dr. Edwin Hubble

  2. What, Why and How • Field Investigations of the environment involve the systematic collection of data for the purpose of scientific understandings. • System thinkers, learn skills of inquiry or practices of science and understand that science doesn’t always occur in a classroom. • Field Investigations are not the same. • Descriptive, Comparative and Correlative

  3. Descriptive involves describing and or quantifying parts of natural system. How many? How frequently? What happened? Comparative involves collecting data on different populations/ organisms or under different conditions. e.g. (times of year, locations,) to make a comparison. Is there a difference in groups, times or locations? Correlative involves measuring or observing two variables and searching for a relationship. Is there a relationship between two variables.

  4. DescriptiveDescribing or quantifying • What types of birds use the school habitat during the school year? • When do hemlock trees pollinate? • How many deer live in Olympic National Park?

  5. ComparativeDifference between groups • Are more insects found in the schoolyard in September, October, or November? • Is wind speed greater near the building or out on the playground in March? • Are soil temperatures the coolest at a depth of 5cm,19cm, or 15cm?

  6. CorrelativeLook for relationships • How does dissolved oxygen change as water temperature goes up in the Blue River? • What is the relationship between number of days over 60F in the spring and germination of sunflower seeds? • As elevations increase, how does the number of Grand Fir trees per acre change in the forest?
