Lab 1: Body Systems Scenarios

Body Systems Scenarios
Students work in pairs and identify which body systems are affected by the activity.

1. A dog, Skipper, is roaming around in his neighborhood. Skipper passes one of his favorite spots and he lifts his leg to urinated on a fire hydrant.

2. Last night Jane began to feel like she had a stopped up nose. Today she thinks she has come down with a cold. She went to the nurse and her temperature was 102 degrees.

3. A young boy, James, went out to play on a June morning in Texas. After a couple of hours the outside temperature began to get very hot. As James is sitting outside in the Texas summer and starts to sweat.

4. Julie has a disorder that the doctors found very difficult to diagnose. Her primary symptom is that her muscles twitch without her control.

5. Kenetra has found a series of books that she enjoys very much. The latest edition of the book series was just released and she sat down in her favorite chair and turned the page in her book to chapter one.

6. Nicole’s class schedule changed beginning second semester. She was walking down the hallway going to her new classroom when she saw a cute guy and started to blush.

7. Tim’s grandmother took him to the doctor’s office because Tim had been feeling ill for several days. The doctor checked Tim’s blood for white blood cells to determine if he had an infection.

8. You are at the Texas Ranger’s World series game. You eat the most expensive hot dog you ever had in your life.

9. Your 4 year old cousin is having a birthday and your aunt asks you to help with the preparations. You blow up a lot of balloons.

10. You are very upset, you start to get angry and your heart starts to beat faster and you want to get in a fight.

11. You have just completed a 5 mile run. You stand at the bottom of a hill taking quick breaths. Your cells need oxygen as fast as possible.

12. A woman begins to cramp. In a few hours her menstrual flow begins.

13. You are talking to a friend on your phone. Your little sister comes into the room and starts to sing Barney songs very loudly in order to annoy you. You yell at your sister.

14. You have a meeting with the principal after 3rd period. You can’t pay attention in class and you cannot stop thinking about the meeting. You start to get scared.

15. You have a headache after your meeting with the principal. You take some medicine and your headache goes away.

Human Body Systems Team Quest Due Jan 4, 2011

Your team’s job is prepare a presentation to educate your classmates about
one of the body systems that makes up the human body. Your presentation must
include the following requirements:
Part 1: Introduction
Tell the name of your organ system and describe the major functions.
Part 2: Diagram
Provide a diagram of your body system with the major parts
or organs labeled with their name and functions.
Part 3: Teamwork
Explain how your body system works with others in the body.
Part 4: Fun Facts
Find 5 facts about your body system or its parts.

Each team will also be provided with a Body System Checklist of important
terms or items that must be included in the presentation. Teams may use their health
textbooks, reference materials, or online resources to research their organ system.
Teams will be allowed five to seven class periods to create a Power Point
presentation and fill-in-the-blank worksheet with a diagram of your system. The
presentation must be made using the Power Point program and saved on a
computer disk provided by your teacher. The presentation must consist of at least 5-
6 slides and no more than 8 slides including the title slide.

Mitosis Vocabulary

Mitosis –the process of cell division including division of the nucleus.

Cancer –disorder caused when cells lose the ability to control growth and continue to divide.

Interphase –part of the cell cycle when the cell is not dividing

G1 –phase of the cell cycle after cell division, growth and day to day life of a cell.

S Phase –Replication or synthesis of DNA and associated proteins that happens before cells divide.

G2 –Phase of the cell cycle when cells prepare for cell division by making more organelles and cytoplasm.

Diffusion – How most water soluble materials get into a cell. process by which molecules tend to move from an area of higher concentration to an area of lower concentration.

Chromosome –Thread like structure with in the nucleus containing genetic information. Made of DNA coiled around proteins.

Chromatid –half of a duplicated chromosome. One of two “sister” parts, makes half of the “X”

Centromere –area where sister chromatids of a chromosome attach.

Cell Cycle –series of events cells go through when they divide.

Prophase – when the chromosomes coil up and become visible, and the centrioles go to opposite sides of the cell.

Centriole –tiny microtubule structure located in the cytoplasm that helps create the spindle fibers.

Spindle –helps separate the chromosomes during mitosis. Fan shaped structure made of microtubules.

Metaphase –when chromosomes line up in the middle of the cell , during cell division.

Anaphase –when the chromosomes pair separates and moves toward opposite sides, third phase of mitosis.

Telophase –when the chromosomes uncoil and disperse into a tangle of dense material. The final phase of mitosis.

Cytokinesis –Division of the cytoplasm and organelles during cell division.
