S TRUCTURE AND S UPPORT Cells, 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.

V OCABULARY : 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.

S CIENCE S TARTER Write the following: The Scientific Method: 1. Ask a question 2. Form a hypothesis 3. Test your hypothesis 4. Analyze results 5. Draw conclusions 6. Communicate results

H OW S WEAT W ORKS : 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”

T HE B ODY B OOK 1. 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 page 6. Raise your hand. 7. Work in your journal.

Science Starter: Tell me about your weekend.

W ARM B LOODED VS. C OLD B LOODED 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. 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. Cold-blooded animals are about the same temperature inside as the weather is outside.

H OMEOSTASIS Keeping me going, and going and going……

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

I A M W ARM -B LOODED This means that the temperature inside my body does not change no matter what the weather is like.

C OOLING M E O FF 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.

W ARMING M E U P When I’m cold, my body makes me shiver. This warms up my muscles so I don’t freeze to death.

H OMEOSTASIS H ELPS M E A DJUST Homeostasis helps me adjust to higher elevations and boats.

S ICK  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 Card Use the paper to make a “thank you card” Thank Homeostasis for making you comfortable and for keeping you alive. Thank Homeostasis for making you comfortable and for keeping you alive. Be creative this time Be creative this time

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

Human Body Video Watch 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 Organs Tissues 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 Systems Organs can’t do it alone, so they must work with other organs to maintain homeostasis. We call this an organ system. We call this an organ system.
