Describe what it’s like to jump into cool water.

STRUCTURE AND SUPPORTCells, Tissues and Organs

WYWKWYLT

I will be able to describe how tissues, organs, and organ systems are related.

I will understand how organ systems work together to maintain homeostasis.

VOCABULARY:

Homeostasis: The maintenance of a constant internal state in a changing environment. It’s a good idea to highlight your vocabulary

words because they will be on your test. Use a highlighter, or colored pencil to make emphasis

of these words. I have highlighters for you to use, but we need to

break and talk about the art boxes because I’m generally unhappy with the way we are treating them.

Write the following:The Scientific Method:

1. Ask a question2. Form a hypothesis3. Test your hypothesis4. Analyze results5. Draw conclusions6. Communicate results

HOW SWEAT WORKS:

Use the cotton swab to wipe the rubbing alcohol on your hand.

Then, blow on your hand. Describe how your hand feels. How does sweating work?

Discussion: listen for the answer Draw a picture of “sweating”

THE BODY BOOK1. Color all sections on both pages of

the body book.2. Cut out on the solid lines – NOT

the dotted lines.3. Glue the blank sides of the two

pieces back to back.4. Fold the booklet correctly.5. Put your name on the back page6. Raise your hand.7. Work in your journal.

WARM BLOODED VS. COLD BLOODED

Watch the PowerPoint on the differences between warm and cold-blooded animals.

What is the fundamental difference between warm and cold-blooded animals? Warm blooded animals maintain a constant

temperature inside no matter what the temperature is outside.

Cold-blooded animals are about the same temperature inside as the weather is outside.

HOMEOSTASISKeeping me going, and going and going……

WHAT IS IT?No matter what’s going on in the world around me, homeostasis keeps me comfortable and alive.

I AM WARM-BLOODEDThis means that the temperature inside my body does not change no matter what the weather is like.

COOLING ME OFF

When I get really hot, I sweat. This is how my

body keeps me cool.

The sweat evaporates off my skin which makes me cool off.

WARMING ME UP

When I’m cold, my body makes me shiver.This warms up

my muscles so I don’t freeze to death.

HOMEOSTASIS HELPS ME ADJUST

Homeostasis helps me adjust to higher elevations and boats.

SICK I hate it when I get sick and have a fever, but I know that homeostasis needs to do this to make me better.It does this to keep other

viruses and bacteria out of me while it fights the one I currently have.

Homeostasis Thank You CardUse the paper to make a “thank you card”

Thank Homeostasis for making you comfortable and for keeping you alive.

Be creative this time

Describe the role of homeostasis. Why does the scale fit with concept of

homeostasis?

Human Body VideoWatch the video

and listen to possible discussion.

WYWKWYLT I will be able to

describe how tissues, organs, and organ systems are related.

I will understand how organ systems work together to maintain homeostasis.

Body Organization Cells, Tissues and Organs

My cells need nutrients and oxygen to survive (maintain homeostasis).

My cells are organized into groups which we call tissue.

Tissue: a group of similar cells that perform a common function.

Tissues

Connective Tissue

Epithelial Tissue

Muscle Tissue

Nervous Tissue

Growing Tissue

Dr. Charles Vacanti of the University of Massachusetts grew a human ear on the back of a mouse.

Tissues Form OrgansTissues cannot

do it alone, so they form organs.

Organs: a collection of tissues that carry out a specialized function of the body.

Organs Form Organ SystemsOrgans can’t do

it alone, so they must work with other organs to maintain homeostasis.We call this an

organ system.

Scientific Method at the Bat Listen to the poem and be thinking about:

Expression: when you read with emotion to show emotion.

Phrasing: read words like they are connected. Phrasing helps readers comprehend the text.

Smoothness: when reading is smooth, not choppy!

Pace: the rate or speed at which you read – NOT TOO FAST --- NOT TOO SLOW. Sounds conversational.

Your Turn

In your journals, write a poem about the scientific methodIt must be at least

eight lines long.When it is done,

we will copy it onto new paper and hang a select few up in the hallway.
