or…)

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