Day 18 10/22/14 Test and Intro to Cells

I’m at (another) meeting. I’d rather be here with you.
______ 1. Turn in your lab book, if you didn’t.
______ 2. Take your test.
______ 3. Start (alone) on the handout, Organelles in Eukaryotic Cells. A eukaryotic cell is a cell whose organelles are covered with cell membrane. (All cells have a membrane around their perimeter. Eukaryotic cells also have membrane around internal structures.)
______ 4. Please write the number of the last question on the Organelles in Eukaryotic Cells handout that you finished in the blank ____________. Complete the handout at least through number 18 for homework.
Also, for homework, please read Chapter 3.1 using your Reading Guide (the blue paper – extras that are now green are on the front table.) WRITE THIS DOWN AS YOU ARE LEAVING THIS PAPER!
Objectives for the reading are: (also write this down)
· Describe developments that led to the cell theory.
· Differentiate between prokaryotic and eukaryotic cells. You will be asked about this on Tuesday.
Have a great weekend!

Day 04 9/11/14 Lab Safety and Pillbugs

We examined some behavior policies for lab and why they are important for everyone’s safety. We considered horseplay, hygiene (eating and drinking and hand-washing) and what to wear, or not.

We started to set up our lab books. If you don’t have one - get one, or see me.


Day 03 9/9/14 How Scientists Learn New Things

Scientists don’t always follow a “scientific method" and neither will we. We will use various methods for designing and carrying our investigations and analyzing our findings. These methods may differ from one investigation to the next depending on the focus of our study.

Also important is the realization that a hypothesis isn’t sort of proven to become a theory and then conclusively proven to become a law. The reverse is more correct. A law is something we observe happening over and over. We attempt to find reasons for this phenomena or phenomenon, and create an explanation. We test it and refine it until the explanation fits the observations and works with other tests. Hypotheses figure in when, based on what is already known, we opt to test a new phenomena or situation. Hypotheses are not “proven;" in fact, science does not seek to prove anything. Collected evidence either allows us to accept the hypothesis or reject it - a hypothesis isn’t right or wrong.

We began to look at the safety equipment around the room, how to use it and when to use it.

Day 02 9/5/14 Learning to read informational text

We went to the textbook depository and checked out textbooks to be kept and used at home. We did the textbook overview on the first page together, and then did our first reading assignment from Chapter 1 Section 3.
