Date: Oct 26 to 30, 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: Squid what it is and what are its 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: new unit, pulled from resources on squid

Brain Activator: Brainpop squid, brainpop invertebrates

Instructional Activities:

            intro the squid video from discovery education and discussion informal assessment of

           prior knowledge.  vocabulary building and art of the heart and digestive system

          drawn and labeled into journals                  

For the squid  how do the same questions apply as in the heart since this specimen has 3 hearts??

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. How does the Squid eat?
9. What are the parts of its digestive system
10. How is it portrayed in literature (cross curricular connections)

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.
