Lesson Plan : The Stages of Mitosis
Teacher Name: | Mr. Jones |
Grade: | Grade 9-10 |
Subject: | Science |
Topic: | Mitosis and Cell Division |
Content: | Mitosis- the process of cellular reproduction Prophase- the chromatin condenses into a highly ordered structure called a chromosome in which the chromatin becomes visible. Metaphase- condensed chromosomes, carrying genetic information, align in the middle of the cell before being separated into each of the two daughter cells. Anaphase- chromosomes separate; each chromatid moves to opposite poles of the cell. Telophase- nuclear envelope reforms, cleavage furrow develops, cytokinesis follows. Cytokinesis- cell divides into 2 daughter cells |
Goals: | To have students fully understand mitosis and its stages. |
Objectives: | Students should cooperate with each other and work in groups of 3 to draw the stages of mitosis. |
Materials: | -Diagram of mitosis on the board or overhead -Video of cleavage furrow and cytokinesis |
Introduction: | Ask: how do grow? Response: we eat food and get bigger. Ask: but exactly what is it that gets bigger on a fundamental level? Let students grapple with this difficult question for awhile and allow them the chance to offer suggestions before explaining. |
Development: | The fundamental unit of life is the cell. Cells don't just get bigger, they actually multiply! This is ultimately why living organisms grow and develop: cellular reproduction (or mitosis). |
Practice: | Distribute pipe cleaners (chromosomes) and have students follow along with you in demonstrating all of the different phases that the DNA goes through during mitosis. |
Accommodations: | Have those struggling spend more time shaping the different forms of chromosomes with the pipe cleaners. For those who master the material quickly, have them model the entire process using any left over pipe cleaners. |
Checking For Understanding: | -Are the students following along with the pipe cleaner activity? -Are they drawing out the stages of mitosis appropriately in their groups? |
Closure: | Mitosis is a fundamental life process that is responsible for the growth, development, and repair of living matter. It's important to be wary of its principles and functions so that you can know what your body is going through. |
Evaluation: | -How well were did their drawings capture the process of Mitosis? |
