Lesson Plans

Name Description
The Making of a Marvel: Part 3

This lesson emphasizes the phases of meiosis and how it is different from mitosis. Students will model each phase using candy worms as chromosomes and other types of candy to represent other cellular structures. This gives students a hands on perspective of meiosis, allowing them to better grasp the differences in phases, as well as to understand the importance of meiosis in sexual reproduction.

Making Mitosis with Yarn

Students will model stages of mitosis and meiosis using yarn. By the end of the lesson, the students will be able to recognize the difference between mitosis and meiosis, know what type of cells are produced from mitosis and meiosis, and how many new cells are created at the end of each process.

This lesson is designed for student with mild/moderate disabilities enrolled in an Access class or in the inclusion classroom with assistance from the support facilitation teacher or possibly an Advanced Placement Biology student.

Mitosis and Meiosis Pipe Cleaner Simulation: Crossing Over and Independent Assortment

This lesson requires the students to simulate the movement of chromosomes during mitosis and meiosis using different-colored pipe cleaners. The pipe cleaners allow the instructor to highlight both recombination (crossing over) and independent assortment, two important components of meiotic cell division. The processes that create variation among gametes are also emphasized.

This lesson plan includes excellent teacher support in the form of videos that explain how the pipe cleaners should be manipulated to demonstrate the concepts of mitosis, meiosis, and independent assortment.

Virtual Manipulative

Name Description
Meiosis or Mitosis This virtual lab has three components: a short tutorial describing meiosis, a series of microscope slides allowing students to identify stages of meiosis, and a karyotyping activity. The first components support student understanding of mitosis and meiosis, as well as gamete formation. The karyotyping activity is fun and interesting for students, but is not necessary for mastery of NGSS science benchmarks.

Worksheet

Name Description
Dragon Genetics -- Independent Assortment and Gene Linkage This is a lab/activity that uses dragons as "research subjects" for genetics research. It highlights independent assortment as well as gene linkage. Students will do the first part of the activity using independent assortment (genes on different chromosomes). The second part of the activity looks at genes on the same chromosome, and how linkage plays a part in allele assortment. It can be used to show how crossing over allows increased variation when involving linked genes.

Worksheets are available in both Word and PDF formats, for both teacher and student. There is an additional dragon genetics lab that illustrates the principles of Mendelian genetics as a whole.
