    WEDNESDAY - 10/31/12 - PARTS OF A CELL

    Are you feeling musical today on this happy Halloween? If so, go explore the music videos about the parts of cells by clicking HERE! :)

    TUESDAY - 10/30/12

    In class yesterday we discussed the six characteristics of life: growth and development, use energy, respond to environment, maintain homeostasis, reproduction, and organization. Now we are going to explore the fundamental building blocks of all living things: the cell. Today your goal is to become familiar with the parts of both an animal and plant cell. YOUR GOAL IS TO CREATE A 3-D MODEL OF A CELL FOR CLASS FOR NEXT TUESDAY, NOVEMBER 6TH.

    To help you in this task there are some resources I would like you to explore. The first would be your textbook. I emailed a PDF copy of the chapter to everyone Sunday evening, but I am also including a copy here.

    Download file "Chapter 8 Life Structure and Classification.pdf"

    The second resource is the website called "Cells Alive!." You may find it by clicking HERE. This website gives good basic information on cell structure and function.

    Here is the cell function worksheet we're using in class.

    I found a useful YouTube video that goes over the parts of a compound light microscope. This might be useful for you in quizzing yourself to get these parts memorized.

    If you happened to miss class today you need to watch the video below and take notes over it. I will give you the accompanying practice problems in class tomorrow.

    Tuesday - 9/25/12

    Hi 7th graders! I am including a video that tells you how to go through the worksheet packet that Fergie will be giving you in class today. If you don't finish it expect to do this as homework and turn it in first thing on Wednesday.

    Monday - 9/24/12

    Last week we worked to improve our understanding of how motion can be measured. After the pop-quiz I realized that we needed to spend just a little bit more time going over how to calculate speed and to redefine our terms. Below you will find a brief outline of key points:
    • Motion is considered a change in position. It is relative to some point of reference..
    • Motion can be measured by distance and displacement.
    • Distance is the total path traveled by an object. (Think of the tennis ball in the air and having a string trace out its path. That would be equal to the distance traveled.)
    • Displacement is the shortest distance between an object's starting and ending points as well as the direction.
    • The speed of an object is found by dividing the distance by the time. (Think if you're running a race: you know the length of the race you will be running, but you don't find out your time until after the race is finished. Therefore, distance is the dividend and goes under the division box. Time is the divisor and goes outside the division box.)
    • If you know the speed and direction an object is traveling, then you know its velocity.
    • An object is accelerating if its velocity changes somehow.
    • Because velocity has two parts to it - speed & direction - if either (or both!) of those things changes for an object then it is known to be accelerating.
    • An object that is turning continuously, like bodies in orbit in space, are constantly accelerating because they are always changing direction.
    • Acceleration can be both positive or negative. For example, if a car is slowing down as it is approaching a stoplight, it has negative acceleration.
    I am including some pages that show how to work out the story problems we designed in class and had to solve for Monday. They might help you in better understanding how to convert units.

    Friday - 9/14/12

    This week we began our unit on Motion & Newton's Laws. We have focused on understanding ways of describing motion as well as calculating speed. Next week we will begin exploring changes in speed, known as acceleration.

    We did an outside measuring activity and homework related to calculating individuals' speeds in meters/second. First we had to convert our distance measurements from feet to meters which involved learning about unit conversions. Some students have struggled with understanding that speed is found by dividing a distance measurement by a time measurement (and not the other way around).

    If you missed class at any time this week you will need to be sure to read the first section of Chapter 23 on Newton's Laws of Motion. Answering the questions at the end of that section should help ensure you are understanding the concepts. You will need to come talk with me to get the makeup worksheet you need to do instead of the lab activity, if you missed it.

    If you are having difficulty converting a Pages document into a PDF, this video will remind you how. It also explains how you attach files in an email so you can send it to someone.

    Wednesday - 8/29/12 - We are currently close to wrapping up our unit focused on the question of "what is science?" Today you completed your gallery walk of each other's cubes. I'd say that although you might not have been able to predict the bottom pattern on all of the cubes, you did an excellent job of using your skills of observation to analyze what was possible. Good job! Be ready to discuss your cubes in class tomorrow as a group.


    If you have missed school sometime between the first day of school through Wednesday, August 29th:

    • Please come check out a textbook from me. The online textbook is not working at the moment.
    • Read Chapter 1, Section 2 starting on page 12 through the end of the section "Recognize the Problem" (ending on page 14). Also read the section about the elephants on page 15.
    • Answer these questions regarding the elephants mini-storr: Why did Dr. Payne include a control group in her investigation?"; How could Dr. Payne sense the elephant sounds if they were below he range of human hearing?
    • Then answer question 2 in the "Self-Check" at the end of section 1.2 on page 18.
