									                                                Observation Lab
Problem: 1) To Practice making astute observations of the natural world around you, including physical environmental
conditions and behavior of any animals (if visible) and to record these observations in detail.

Materials: Beaufort Scale for Wind, plant book, Cloud Type Diagram, Thermometer, compass, magnifying glass, ruler,
CA field guide book, paper towel

Physical Environmental Conditions
   1. Use the Modified Beaufort Scale to determine Wind Speed. Estimate Wind direction by using a compass. Hold
        something light, like a strand of hair, leaf, petal…and see which way it is blown.
   2. Look at the sky and estimate percent of cloud cover. Look at the horizon in all directions and make note of any
        differences in clouds.
   3. Use the Cloud type chart to name the type(s) of clouds present.
   4. Use the thermometer and determine outside air temperature in Celsius. Record temperature.
   5. Walk to the little creek, hold the end of the thermometer under the water, but not touching the bottom of the
        creek. Keep under water for a few minutes. Record temperature.
   6. Make observations about the general condition of the creek: water clarity- Can you see the bottom of the creek?
        Touch the end of your ruler to the bottom of the creek, at which measurement can you no longer see the ruler?,
        How deep is the water? What color is the water?, flow, amount of trash, smell, size of creek across.
   7. Describe in detail general weather conditions of the day. This can either be a paragraph or a list.

Plant and Animal Observations
    8. Examine various plants along the creek. Identify at least one plant using the field guide books. Start by looking at
        the shape of leaves, how the leaves are clustered, if any flowers are present, veins in the leaves, etc.
    9. Draw a picture of the plant.
    10. Try to locate a living creature: either bird, reptile, insect, or mammal. You need to watch this creature for at
        LEAST 5 minutes! Describe in detail what that animal does during the 5 minutes.
    11. Try to identify what you think the animal’s food sources may be.
    12. Remember, the more descriptive you are, the better!
