Title: How Cells Divide
Grades: 9-12
Time 45
Standards:
·
Describe and explain the structures and
functions of the human body at different organize- tonal levels (e.g., systems,
tissues, cells, organelles).
·
Major Understanding’s 1.2a important levels of
organization for structure and function include organelles, cells, tissues,
organs, organ systems, and whole organisms.
·
1.2c the components of the human body, from
organ systems to cell organelles, interact to maintain a balanced internal environment.
To successfully accomplish this, organisms possess a diversity of control
mechanisms that detect deviations and make corrective actions.
·
1.2e the organs and systems of the body help to
provide all the cells with their basic needs. The cells of the body are of
different kinds and are grouped in ways that enhance how they function
together.
·
1.2f Cells have particular structures that
perform specific jobs. These structures per- form the actual work of the cell.
Just as systems are coordinated and work together, cell parts must also be
coordinated and work together.
- CCSS.ELA-Literacy.RST.11-12.1 Cite specific textual evidence to support analysis of science
and technical texts, attending to important distinctions the author makes
and to any gaps or inconsistencies in the account.
·
CCSS.ELA-Literacy.RST.11-12.5 Analyze how the text structures information or ideas into
categories or hierarchies, demonstrating understanding of the information or
ideas
Materials: smart
board, lap tops, mitosis diagrams map, color pencils, 5 lap tops, multimedia
text-How Cells divide-PBS/NOVA
Goal: students
will know each sequence stages of mitosis and be able to explain each stage as
they occurs.
Essential
Questions:
·
Why must
a cell divide?
·
Explain
mitosis and why it happens?
·
What
happens to the nuclear membrane during mitosis?
·
Explain
the final stage Mitosis and give details-
Students Will:
·
Understand
why cells divide and not just get bigger
·
Understand
the sequence division of a cell
·
Explain
what happens to the nucleus during division
·
Describe
what happens in the final stage of mitosis
Performance
task:
·
Mitosis
animation, brain pop quiz, accountable talks, group discussions, diagrams, give
accountable talk, PBS/NOVA
Other Evidence:
·
Complete
animation, diagrams, test-label sequences, accountable talks, group’s
presentations
Learning
Activities:
Connect student
to prior knowledge-If cell don’t divide predict what would happen to the
organism? Give Students plenty of time to answer the question. Explain that
cells have a specific function and part of that function is cellular division
for organism survival.
Hook-Show brain
pop video and stop at each sequence highlighting the difference. Let student
take the short quiz.
Re-aloud from
the text pages 322-325 and ask the students question and clear up
misunderstandings. Students will take notes while re-aloud text is on the smart
board.
Introduce
students to NOVA/PBS interactive cite and remind students of inter-net safety.
Student groups
will complete mitosis sequence maps using the multimedia text.
Students will organize
details of mitosis sequences maps, revise and reflect on detailed information. Share
out main, points and ideas of text details in groups.
For differential
instruction-lower level groups will be paired with higher leveled students. Quite
student will be given plenty of time to solve problems and turn and talk
sharing ideas. Brain pop, multimedia text, mitosis sequence maps and group
presentations.
For closure
student will present sequence maps and details of findings.
