Title: Modeling Meiosis and Gamete Formation
This module includes hands-on and inquiry-based activities related to the processes of meiosis and gamete formation. Using yarn and pop beads, students will simulate the changes in chromosome pairs during the various stages of meiosis. The students will use Playdough to model the formation of the sperm and egg cells. Students will denote the differences in cytokinesis and explain the reasoning for the differences.
Standard(s): [S1] (7) 9: Identify the process of chromosome reduction in the production of sperm and egg cells during meiosis.
Title: Gene Puzzles
In this Science NetLinks lesson, students come to understand that in sexually reproducing organisms, such as humans, typically half of the genes come from each parent. They examine a fictional pedigree and determine which gene is responsible for a given trait.
Standard(s): [S1] (7) 11: Identify Mendel's laws of genetics.
Title: A Mendel Seminar
This Science NetLinks lesson, constructed around Gregor Mendel's 1865 paper, is an advanced lesson in history, scientific inquiry, methodology, classical genetics, and plant biology. In this lesson, students are guided through a thorough discussion of part of the paper Mendel wrote about his pea plant experiments.
Standard(s): [S1] A&P (9-12) 12: Identify structures and functions of the reproductive system.
