Today we reviewed the presentation guidelines (see below) and students worked in their groups on their presentations.
Presentation Guidelines:
1. 3-5 minutes in length
2. Everyone must speak
3. You should include general background information on the type of cell
4. The purpose of this type of cell in our body
5. 3-5 images
6. You must cite you sources! This means you need to have a bibliography for all of your text and images.
7. Your presentation must be emailed to me before 12:00 tomorrow! Why? This way I can have all of the presentations loaded and ready to go before class starts.

Major Types of Cells
Today we talked about five major types of cells: nerve, muscle, skin, fat and reproductive. Tonight for homework, you should begin working on your presentation.
Remember: your presentation should be 3-5 minutes.
You should include:
General background information on the type of cell.
The purpose of this type of cell in our body
3-5 images
Since there is only a short amount of time to prepare this presentation, you do not need to make a handout. Your peers will take notes during your presentation.

Today we continued to look at slides using light microscopes. Below is a cross section of the gallbladder. In addition to slides of the digestive system, we looked at slides of the circulatory system.
Homework: Read and take notes on the information on this webpage. You will have a reading quiz. A good ol' fashioned paper quiz.

Stomach Dissection
Today we dissected pig's stomachs outside on the DeNobili terrace....during lunch! Pictures will be posted later tonight.
On Friday you will be looking at some of the tissues samples you selected under dissecting microscopes. You will also be using a new type of microscope, called a compound light microscope.
Watch the video below on how to use a compound light microscope. You will have a short prelab quiz on how to use a microscope.

Digestive System Day 1
Today students took a quiz to recap the circulatory and respiratory systems. Then we started to learn about the digestive system.
For homework, watch the video clip below. You will need to take notes. Pause the video to write down key points about how food is digested.
You will have a quiz on this video tomorrow, so any notes you take you can use.

Wrapping up the Respiratory System
Today we wrapped up our investigation with the dialysis tubing. We used this as a model of capillaries to learn about osmosis and diffusion.
To survive we rely on the the diffusion of oxygen into our blood from our lungs and the diffusion of carbon dioxide from our blood into our lungs.
We also saw that only the red food coloring and the water were able to move through the membrane, but oil and the black food coloring didn't move through membrane. From this we learned that membranes are selectively permeable.
Homework: you have a quiz on the circulatory and respiratory system.

Builing a Model Lung
Today students worked in groups to build a model of a lung. Below are some of the key points we learned during this activity:
When the diaphragm contracts (flattens/pulls down), air is pulled into the lungs. When it relaxes, air is expelled from the lungs.
There are thousands of bronchioles in the lungs, at the end of these are small air sacks called aveoli. Gas exchange happens at these aveoli.
Homework: Make an observations/patterns/explanations table for the respiratory system. This should be a new page in your notebook and go directly behind the orange 'o/p/e' table in your notebook.
We will be using this table for an experiment tomorrow.

Take a deep breath!
We are starting a two week unit on the respiratory system. Today we brainstormed what we know, think we know and want to know about the respiratory system. We also compared the lung capacity of two students and started our first engineering challenge of the year.
Tomorrow you will build a model of a lung. You can certainly do research before coming to class to learn more about how the lungs work.
You will have rubber bands, tape, plastic bottles, straws, balloons, plastic bags, modeling clay and paper to make your model. You can not breathe into the model to inflate the lungs.

Heart Dissection
Today we had "the coolest science class ever!" Students dissected cow hearts and used dissecting microscopes to take a closer look at parts of the heart. Click the picture below to link to all of the pictures.
Homework: finish your observation tables from today.

Cow Heart Dissection Prelab
Today in class we took a few more notes on the heart and compared fish circulatory systems to human circulatory systems.
Tomorrow we will be doing a how heart dissection. Watch the video below to have an idea of what you are in for.

Heart Rate Lab Intro
Today we started the heart rate lab. Students learned some basic information on the flow of blood through the heart and practiced taking their pulse.
Homework:
Finish writing the procedure for the experiment. In class we wrote the procedure for the dancing test (see it below). You need to write the procedures for tests 2 and three (running and jumping).
NOTE: change the activity and recovery times to one minute, instead of two minutes.
Test 1: Dancing procedure
Students sat quietly for 2 minutes before taking their resting pulse. The pulse was taken for 30 seconds, multiplied by 2 and entered into the data table. Students danced for one minute. At the end of one minute, their pulse was taken for 30 seconds, multiplied by two and entered into the data table. The procedure was repeated two more times, for a total of three trials.

Welcome Back!
From now until Academic Travel we will be focusing on the following two objectives:
Students will be able to identify the general functions of the major systems of the body and describe ways that these systems interact with each other.
Students will be able to describe the hierarchical organization of multicellular organisms from cells to tissues to organs to organ systems.
We are starting our anatomy unit with the circulatory system. Tonight for homework read page 98 and answer the questions at the bottom of the page. You do not need to write the question, just the answer. Write you answer using complete sentences.
