September 5/6

Bell Ringer:  Define autotroph and then list the kingdom(s) of life that contain autotrophs.
Today we spent a lot of time reviewing as a class.  We went over experiments, levels of classification, and 6 kingdoms of life.  Here is the shortened version of our discussion:
Whirly Bird Lab: Independent variable (modifications to whirly bird), dependent variable (drop time), control (original whirly bird), controlled variables (drop time, paper, etc) What type of experiment is this?  (controlled)
If I wanted to learn whether my neighbors dog barks more when the weather is warmer, what type of experiment is this?  (correlational)  How could I set up this experiment?  (over the course of several months record the temperature and number of barks)  We talked about how we would graph this info (x-axis temperature and y axis # of barks per hour).  We also talked about how correlational studies do not give us a cause.  For example: if our data showed that the dog did in fact bark more when it was hot it could be because there are more people outside when it is warm.
What are the 7 levels of classification:  kingdom, phylum, class, order, family, genus, species
We also reviewed the 6 kingdoms heavily.  You don't need to memorize the chart, but you should be able to recognize which kingdom when given characteristics.  For example, a multicellular, heterotrophic, and mobile organism would be animal.  Multicellular rules out bacteria and archaebacteria and heterotrophic protists, heterotrophic rules out algae (protist) and plant so animal is the best choice.
Next, we took a 10 point quiz which we graded during class and then we began a worksheet on metric measurements.

Make Up:   Quiz (see me before/after school or falcon time) and measurement worksheet (sorry I don't have a digital copy so see me)
