Activity 12B: What’s Happening Inside?October 3, 2013

Getting Started: What do you know about the organs and systems of the human body? Brainstorm as a class.

Introduction: Read pg.B-10 and Write your own RACE question.

What’s Happening Inside?

Organs are structures composed of one or more tissues that perform a function or a group of functions in the human body. Several organs working together to perform a function are a system. One example of this is the excretory system. The function of the excretory system is to remove liquid waste from the body. Because the kidneys help perform this function, they are organs in the excretory system. You may be familiar with the organs and functions of our other system, such as the digestive and cardiovascular systems. Use your knowledge of the human body to look more closely inside your self. In the photos on page B-10 which organ system help each of the students do the activities shown?

Challenge: Rewrite the challenge question in your own words.

Key Words: Cardiovascular System, cell, digestive system, excretory system, function, muscular system, nervous system, organ, reproductive system, respiratory system, skeletal system, structure, System (body system)

Procedure: Have you read and do you understand the procedure on pg. B11? Write one sentence that describes what you will be doing.

Analysis: Answer Analysis Questions 1 through 3.

Reflection: What new things have you learned about the human body in this activity?

Laying It Out

• Each student in a group of four chooses three organs to draw in the outline. You may not do the same on as someone else.

• Write the function as close to the organ as possible. Try not to get in another organs way.– If you are having trouble reflect on past experiences and

do your best.• When you have finished write questions you have

around the outside of your body.• Then move around the room looking at the work of

others and record any questions you can not answer in your notes.

Classifying Organs

• Work together to organize the various Organ and Structure Cards and record the groupings you have formed.

• In your group, discuss the function of each organ and write down the name of any organ whose function you are not sure of.– As you sort the cards, place them in rows, not

piles, and leave the cards in place once you have finished.

Discussion

• How did you classify your organs?

Leave your Organ and Structure Cards in rows

Put systems to cells 1&2 here

Organ System

• Use the Organ and Structure Cards with the Organ Function Cards and separate them into systems, then record you information on Student Sheet 12.1; Functions of Human Body Systems

Part C: Modeling the Human Body

• A lot of your pictures had areas of open space. – What is in these areas?

• Press along your waist, arms, and legs. What do you feel? Do you feel empty space? What types of structures can you feel?

Instructions

• Use only plastic human body models that are lined with plastic. If you are unsure ask!!!

• Use the back as your base • Use Table 1: Organs and Structures to Model

as a guide.• Clean up when you are finished.

Part D: Reviewing Structure and Function

• Place pictures of models and have students discuss where the body parts are in relation to there own body.

• Color 12.2a and 12.2b

Question 1

• Look at the drawing you made in Part A. List some structures or organs that were not the right shape or size or were in the wrong place on your original drawing. Explain how you would change them if you could redraw the diagram.

Question 2

Look at the questions that you recorded in your science notebook after Part A. Answer all of the questions you can answer. Discuss with your group any that you are still not sure about.

Question 3

• The liver is the largest internal organ of the human body. Was the liver the largest organ in your clay model? Do you think that the other organs you modeled in he clay were accurate in size? Why or why not?

Question 4

• What are some of the limitations of the clay model you made of the human body in Part-C?
