Date: Sept 28 to Oct 2, 2020

TEKS: 7.3A TLW gather evidence to compare and contrast dissection subjects using scientific explanations, (B) draw inferences based on data (C) represent the natural world using models and identify their limitations

Enduring Understandings: Heart, a vital part of the Circulatory and Cardiovascular systems

Essential Question: How is the Heart, a part of the Circulatory and Cardiovascular system, similar in function for animals as living creatures?

Key Concept: What is the heart and what does it do that is so important.  What is the structure of the heart?  Does it vary and if so why.

Essential Vocabulary: Apex / Aorta / Artery / Atrium / Coronary Artery / Interventricular Septum / Ventricle / Vein / Circulatory System / Cardiovascular System / Capillary

Brain Activator: Brainpop heart, brainpop cardiovascular system, united streaming video

Instructional Activities:

1. will be Heart Introduction, using Brainpop and Discovery education
2. we will begin vocabulary and drawings of the pigs’ heart
3. All students will once complete regarding the heart will repair low grades and if we have time Wednesday and Thursday we will find out about our hearts, and how to keep it healthy, and how to monitor that process
4. we will watch dissection of the pig heart videos and discuss the process
5. Pig Heart Dissection upon return to physical classroom

            intro heart video from discovery education and discussion informal assessment of prior

               knowledge.  vocabulary building and art of the heart, drawn and labeled into journals

              (if finished in this class period, next period is assessment)

1. Prior knowledge questioning and discussion
2. What is the heart and what does it do?  How?
3. What systems does the circulatory system work with? How? Why?
4. What is blood?
5. What is a muscle contraction?
6. What connects the parts?
7. Which directions can the blood flow or be pumped?
8. What is blood pressure in humans?
9. What is and why is heart rate important?
10. How is blood pressure measured?  Diastolic and systolic or a normal reading, your blood pressure needs to show a top number that's between 90 and 120, and a bottom number that's between 60 and 80. When both your systolic and diastolic numbers are in these ranges, you're considered by the American Heart Association (AHA) to be within the normal range for blood pressure.Jun 8, 2016
11. How to find your pulse.
12. What is a target heart rate and how is it achieved?  
13.  What does it do?  
14.  Are there other terms for the heart muscle and its function within the system?  What are they?

6,7 TL’sW learn about their heart rate and the importance of monitoring it throughout their life.  We will do the brainpop’s then finish the information packet on the heart which includes the vocabulary

8,9 TL’sW Dissection of Pig Hearts

Assessments: Informal will be done in individual and group discussions throughout the lab unit

Formal will be a written format and cover all specimens dissected to date.  There will be labeling of pictures, vocabulary matching and fill-in the blank, and true false questions on the test.  During the practicum of the heart there will be feedback from student experts and facilitator.

Materials: Packet as provided by Carolina Biological Company/ Pig Hearts / Scalpel / Mall Probe / Tweezers / newspaper matting /clock / fitness sheet to attach to journal
