Field Investigations

“Using his senses man explores the world around him and calls the adventure, science!”

Dr. Edwin Hubble


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


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.


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?


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?


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?
