10/24 classification

In-Class:
Lecture: Students took notes on the history and purpose of classification.
Homework:
Study notes and rewrite them if they are not legible. You need to be able to read your own writing in order to study.



Some groups discussed the detail that a species is identified as closely related organisms that mate to produce offspring that can also mate and reproduce. Two examples of organisms that are produced by animals that were similar but not in the same species are the mule (donkey and horse mating) and the zorse (zebra and horse mating.)

10/23 classification lab

In-Class:
Discussed classification systems. Students arranged shape cut outs into meaningful groups based on their similar characteristics. Tomorrow we will discuss, in detail, the history of our current classification system for living organisms.
Homework:
The few students who did not complete the classification assignment in class must complete it at home. You may use glue, glue stick, or tape to attach the shapes to the construction paper.\

We discussed the fact that while students may not receive written assignments each night, they are required to study their handouts and notes each evening for at least ten minutes. Low test scores most often result from a lack of study time at home.

10/10 metric temperature

In-Class:
We reviewed the scientific method packets in class and students received credit for the work completed.

Students received a conversion worksheet that gives the equation for converting back and forth between degrees Celsius and degrees Fahrenheit. We also discussed standard temperature readings for boiling point of water, freezing point of water, room temperature, and body temperature in both Fahrenheit and Celsius. Students should know how to convert between Celsius and Fahrenheit but what is more important is that they can identify whether the number given is reasonable.
Homework:
Hours 1,2,4 and 6 complete the six conversion problems from the worksheet. We completed at least two examples in class. All classes should memorize the standard temperatures.

You can check your conversions or practice converting other units within the metric system at www.convert-me.com
