Lesson Plan by Carolyn Tyson          10/98
Topic:  Circulatory (Cardiovascular) System
Grade level:  Fourth
Primary curricular area:  Science/Health
Connected curricular area:  Math (Averaging); language arts.
Curriculum objective:  List the components of the Circulatory System and describe their function
Resources:  Multimedia computer; projection plate and overhead or TV; video disk player; Adam, the Inside Story CD; Horizonís 4th grade Science book,  Horizonís 4th grade video disk and guide,  bar code reader; stopwatch; and a simple valve.  Preload video disk and ìplayî up to Main Menu.  Place the Adam CD in drive and load the Adam software (from the hard drive); click Scrapbook;  select Cardiovascular System; arrow forward to "Components of the Cardiovascular System" and click the pause button.
Activities: 
     1. With the entire group, use Horizons video disk segment on circulation for simple explanation of  the circulation system.  (Scan the Circulatory bars on page 21 video disk Guide and hit "play".)  Make a connection between circulatory system &  plumbing system in a  house (pump, pipes and fluid). 
     2.  With the full group, use the CD, Adam, the Inside Story, to study the Circulatory System in more detail. 
       *Identification of the parts of the circulatory system, their functions, and the composition of blood, can be viewed by clicking on the "Components of the Cardiovascular System". 
       *To investigate the clotting factor of blood, click the Blood Clotting picture. 
       *To investigate the vascular system and the three types of blood vessels, click on the Blood Flow picture. Discuss the concept of a circuit. 
       *To observe the cardiac cycle and the parts of the heart, arrow  forward past the Nutrient Exchange section to the Heartbeat picture.  Demonstrate the concept of a valve. 
    3.  Divide class into 4 groups to read an assigned section in the text and report, using no more that Three sentences to summarize the important information and report it to the full group.   Group 1 reads p. 414-415 and  addresses question of the function of the circulatory  system.  Group 2 :  p. 416 on Blood.  Group 3:  p. 417 on parts of the heart.  Group 4:  p.  420 -421 on blood vessels.  All students study the chart on page 418-419. 
    4.  Discuss the term pulse and how to take it. 
Assessment:
    1.  Assign Lesson Review p. 421 from  text.  Resources- text or Adam software.
    2.  Each person takes their pulse according to steps A-D on p. 430  of Horizons text and describes, in a short paragraph, the result in terms of the 3 components of the Circulatory System.
Enrichment/Extentions
    Students will work in pairs to examine the heart using the 3D heart animation (#1 in Navigation) and assemble the heart puzzle (#2 in Navigation). Use pulse data to create a bar graph in order to analyze and display data.
Navigation guide for students:
    1.  Animation - From the Adam Main Menu (close Scrapbook, if necessary) select 3D button; then heart.
    2.  Puzzle - From the Main Menu, select  Anatomy; from the Explore menu, select Activities; Heart puzzle.
