Chapter 1
microscopes, lab write-up, variables

Variables (UP pages 19-20)
independent variable- what you change
dependent variable-what you measure
control group-stays the same so other variables can be
compared to it

In Surface Tension Lab:
independent variable- soapy water
dependent variable-number of drops that fit on penny
control group-penny with tap water

Termite lab write-up (UP pages 25-29) due 9/10
Rough draft due 9/7 (optional)

-Follow template in UP page 27-29
-include cover page, no header on other pages
-Label paragraphs with roman numerals
-each "*" should be its own paragraph labeled with a capital latter under the roman numeral catergory
-include a graph or diagram
-no contractions!
-bibliography must be alphabetised

Microscopes (UP pages 31-34)
-eyepiece is 10x
-objective lenses range from 4x to 100x
-multiply 10x by magnification or objective lens to get total magnification

coarse adjustment knob-brinsg specimen into view
fine adjustment knob-sharpens image
diaphragm-controls amount of light passing through hole in the stage
stage-holds slide in place
stage clips- prevent slide from moving

-work on microscope lab p. 31-34
-termite lab report

Aug 26,2010 - Scientific Method

James C
CH 1
Intro to Biology / Scientific Method
biology – the scientific study of life

ecology – the study of relationships between organisms and their environment

scientific method - 6 steps used to solve a problem using deductive reasoning (general to specific)
The 6 Steps of the Scientific Method

[Observations] – using sight, touch, smell, and hearing, take note of the things you’re experimenting with; get to know what you’re working with

[Question] – come up with a question about something regarding the experiment that you’d like to know more about

[Hypothesis] – create an educated guess used to predict the outcome of the experiment (“if…then…” logic)

[Prediction] – predict the results of the experiment you are about to do

[Test] – start the experiment and check if your hypothesis was correct! If your hypothesis was correct, keep making predictions and keep testing them. If your hypothesis was incorrect, fix it or create a new one.

[Result/Theory] – analyze the results of your experiment or even come up with a theory based on what you learned from the experiment
The 2 Types of Scientific Study

1. Hypothesis-Driven Science -Uses scientific method
2. Discovery-Driven Science Observations, measurements, research, findings
Pyramid of Life

Atoms -> DNA -> Genes -> Cells -> Tissue -> Organs -> Organ Systems -> Organisms ->
Populations -> Communities -> Ecosystems -> Biomes -> Biosphere -> Planet Earth
**Good experiments have 1 variable, a control group, an experimental group, several trials, and more than 1 subject.

**Hypothesis vs Theory - Theories are broader and supported with solid evidence.

** 3 Domains of Life -
1. Bacteria (prokaryotic cells)
2. Archea (prokaryotic cells)
3. Eukarya (eukaryotic cells)

- all life is connected
- we have common ancestors

**Species on Earth
~280,000 plant species
~50,000 vertebrate species
~750,000 insect species

1.  Finish surface tension lab
2. UP p. 11-18
3. Read / annotate UP p. 25-26

Let's Get Started...

Hi There! You found our blog! This is the place to talk about what's happening in class; to ask a question you didn't get a chance to ask in class; to find out what you missed if you were absent, for parents to find out "How Was School Today;" to share your knowledge with other students. Most importantly it's a place to reflect on what we're learning.

Before you can get blogging, please follow the instructions on Moodle for instructions on how to become an author on our blog. Be sure to choose an appropriate screen name for yourself that can be used to identify you WITHOUT using your last name. Please read this post completely and refer back to it if you have any questions about blogging.

The Scribe Post

So, what's this whole blogging thing and how will we use it in class? Well, that is a great question that we will answer together over the course of the year. Blogging is new to me too, so we will figure it out together! Every day one student will be responsible for creating a post to document what went on that day in class. These posts will be called scribe posts and will make up much of our blog (at least to start!). The student who makes the scribe post for the day will assign the next day's scribe the end of their post. Refer to the Scribe List for more information.


Labels, also referred to as tags are important to keep our blog organized and for me to keep track of your contributions for your grade. If you don't label correctly, I cannot give you credit for your work! You must include the following 3 labels: your name (first name, last initial... for example, mine would be DeborahS), the unit we are studying (refer to moodle for the name of the unit), and the type of post that it is. For now, the two types of posts will be "scribe" OR "on my mind". As we continue on this journey, we may introduce more types of posts.

Important Words About Ethics

Blogging is a very public activity. Anything that gets posted on the internet stays there. Forever. Deleting a post simply removes it from the blog it was posted to. Copies of the post may exist scattered all over the internet. That is why we are being so careful to respect your privacy and using first names only. We do not use pictures of ourselves. This is important not only for our blog but for online activities in your own life. Use good judgement.

Below are 4 guidelines that you will be expected to abide by.

    1.  Blogspaces are to be treated as classroom spaces. Speech that is inappropriate for class is not appropriate for our blog. Engaging in conversation and debate with your classmates is encouraged, however, remember to always be respectful. 2.  Never EVER EVER give out or record personal information on our blog. Don’t share anything that you don’t want the world to know. 3.  Again, our blog is a public space. And if you put it on the Internet, odds are really good that it will stay on the Internet. Always. That means ten years from now when you are looking for a job, it might be possible for an employer to discover things about you from your younger years. Be sure that anything you post you are proud of.... or else it can come bag to haunt you! 4.  Never link to something you haven’t read. When you link to something, you should make sure it is something that you really want to be associated with.

This is The Scribe List. Every possible scribe in our class is listed here. This list will be updated every day. If you see someone's name crossed off on this list then you CANNOT choose them as the scribe for the next class. This post can be quickly accessed from the [Links] list over there on the right hand sidebar. Check here before you choose a scribe for tomorrow's class when it is your turn to do so. IMPORTANT: Make sure you label all your Scribe Posts properly (Your Name, Unit Title, Scribe) or they will not be counted.

Friday, August 6, 2010


Every class period will be summarized by one student on the BLOG.  The scribe, student summarizing the class period, will know before the start of class that they are responsible for posting the summary that evening.  At the end of their post, the scribe names the next scribe until all students have posted once.
