UCI Summer Science Institute WebQuests - 2001

UCI Science WebQuests from all years

Students will investigate how blood circulates through the heart chambers, the parts of the heart, and its vessels.

Resources Needed: Attached web pages
Student Science notebook and pencil
Student computers with internet access
Large model of heart on playground or a large poster board model of the heart on the fourth linked web page
Ping pong balls, bean bags, 2 boxes, index cards with body part and heart part names.


Structure of the Heart 

The heart is a muscular organ located just to the left of the breast bone 
(sternum). It is about the size of your fist, and this amazing muscle pumps 
4300 gallons of blood a day. The heart has four chambers: 

Atria. The top two chambers that receive blood from the body or lungs. 
Ventricles. These are the bottom two chambers of the heart. The right ventricle pumps blood to the lungs to pick up oxygen, The left ventricle pumps blood to the rest of the body and is the strongest chamber. 
Valves. There are four valves in the heart that help to direct blood flow. As they open and close, the valves produce sounds that can be heard with a stethoscope. The heart sounds can often tell your doctor about your heart's function. 

Function of the Heart 

Every cell in your body needs oxygen in order to live and function. The role 
of the heart is to deliver the oxygen-rich blood to every cell in the body. 
The arteries are the passageways through which the blood is delivered. 
The largest artery is the aorta, which branches off the heart and then 
divides into many smaller arteries. The veins carry the deoxygenated blood 
back to the lungs to pick up more oxygen, and then back to the heart once 
again. Blood flows continuously through the circulatory system, and the 
heart muscle is the pump which makes it all possible! 

Your Task:

Activity 1:

  • View a website to find out background on the heart and circulatory system. You will watch a 3 minute movie clip and answer a 3 minute quiz. Write answers to quiz in your Science notebook.

    Activity 3:
    • View this lesson on the parts of the heart and answer the questions on-line.
    • When finished press the BACK green arrow key to return to this webpage.

    • Click on:  Kidport
    Activity 4:
    • READ all directions before clicking on website:
    • View the heart on this webpage, and click on each label and read the descriptions of each part of the heart.  Press BACK button after each word to return to the diagram.
    • You will use this information to fill in Activity 5. 

    • When you are done press the BACK arrow key until you are back to this webpage.

    Activity 5:
    • You will be viewing a template of the heart.  Write the numbers 1-9 on your science notebook and write the corresponding answers.  Turn in your notebook.
    Activity 6:
    • READ all directions before clicking on website:
    • You will link to Puzzlemaker.  Once in Puzzlemaker make a crossword puzzle using the vocabulary words you have learned in this lesson.  You will need to input the meaning of your vocabulary, used within the context of a sentence or as a separate meaning. 
    • Print 2 copies and have another student  complete one for homework.  Turn the first copy in with your name on it.  Both student names need to appear on the second copy when it is turned in tomorrow.
    • When you have printed your puzzles, return to this webpage by pressing the BACK arrow several times.

    • Click on:   Puzzlemaker

    Extra Credit:  Find a website that will help you learn how the heart is connected to the rest of the body. 
    Write a short description and write down the website address in your Science notebook.
