  1. Sheep Heart Prelab We will be writing this together so you need to keep up!

  3. FINAL PRELAB DUE end of class (extra credit) or for next class • Cover Sheet • Introduction (4 paragraphs) • BIG IDEA • Hypothesis • Purpose • EACH SECTION HAS A HEADING

  4. Cover Sheet • Title: Sheep Heart Dissection • Graphic (sheep, or heart, or dissection tools or…) • YOUR NAME • YOUR PERIOD • DUE DATE: February 12, 2015

  5. Introduction • DO NOT NEED TO TELL ME YOU ARE GOING TO WRITE A LAB REPORT. • Consists of 4 paragraphs (we will write these next) • Use your class notes (circulatory notes) and lab handout (Heart Dissection LAB) to complete the paragraphs/sentence starters!

  6. Paragraph #1 • Tell me the parts that we can find in a human heart • Ex 1st sentence: The human heart contains four chambers, four valves and five blood vessels. • Then Write at least 3 detail sentences • 2nd sentence starts like this: The four chambers are the….. • MAKE SURE you have a CONCLUDING SENTENCE!

  7. Paragraph #2 • Tell me what each “category” of heart part does • Ex: Each part of the human heart has its own function. • Write at least 3 detail sentences • 2nd sentence: The atria receive blood into the heart while the ventricles…… • MAKE SURE you have a CONCLUDING SENTENCE!

  8. Paragraph #3 • Tell me the flow of blood through the heart • Ex: Blood flows through the heart in a repeated, predictable pattern. • Write at least 3 detail sentences • 2nd sentence: Blood from the body comes through the superior and inferior vena cavae to the … • MAKE SURE you have a CONCLUDING SENTENCE!

  9. Paragraph #4 • Now you are going to link the human heart to the sheep heart and explain WHY we are dissecting a sheep heart. • Ex: The sheep heart contains similar parts and works in a similar fashion to the human heart. • Write 2 detail sentences and 1 commentary sentence • 2nd sentence: For example, the sheep heart contains the same chambers, valves and….. • The commentary should say WHY we do not dissect a human heart • MAKE SURE you have a CONCLUDING SENTENCE that leads into the Big Idea!

  10. BIG IDEA • YOU CAN USE THIS SENTENCE: • We are doing this lab to determine if a sheep heart is comparable to a human heart.

  11. Hypothesis: • YOU CAN USE THIS SENTENCE: • If I dissect a sheep heart, then I will find out that it is comparable to the human heart.

  12. Purpose: • YOU CAN USE THIS SENTENCE: • The purpose of this lab is to see and dissect a three dimensional sheep heart. Also, I will practice safe laboratory technique and writing a lab report.

  13. Videos • http://www.zerobio.com/dissectab_videos.htm • Watch “Sheep Heart Anatomy” video • Watch “Sheep Heart Video” • You can also watch the additional videos: • The Dissection of the Sheep Heart • Mrs. Johnson Sheep Heart Dissection
