Reebops a Model "Organism" for Teaching Genetics Concepts
Reebops are cute, marshmallow-based creatures that can be used to teach inheritance. Beginning biologists draw strips of paper that represent chromosomes from two envelopes, one for the father, and one for the mother. Each parent contributes an allelle to help determine the traits for the baby reebop.

Again, the basis for trait inheritance and the impact of alleles in phenotypes was covered in previous videos. This presentation focuses on gender and the likelihood of traits if they are sex-linked. Sal tells a great anecdote about where the blame should have been placed for Henry VIII's female offspring.

Mitosis, Meiosis and Sexual Reproduction
This video assumes certain knowledge of how variation is introduced and that sexual reproduction results in a combinations of DNA from the parents. Important vocabulary is introduced and defined. There are also examples of gametes, zygotes and the different types of cells and structures involved on an introductory level.

The Way We Were: Embryological Development and Disease
Students use microscopes to study live fish embryos and animated diagrams of cell division on the Internet. They see that scientists rely on technology to enhance the gathering and manipulation of data. They create web pages on cloning.

Sexual and Asexual Reproduction
Students differentiate the processes involved in sexual and asexual reproduction. In this plant science lesson, students discuss the pros and cons of both methods. They explain how sexual reproduction can lead to genetic diversity.

Cell Cycle: Cell growth, Cell Division
Whenever your students have a question about a stage of mitosis, you can be sure that viewing the relevant slide from this show will help their understanding. Covering the complete process of mitosis, this PowerPoint has images and examples of cell division along with details of some single cell specializations.

Genetics and the Work of Mendel
Excellent examples and clear diagrams in this PowerPoint will help you explain the genetics of alleles and the combinations of hybrid crosses. A high school class would appreciate having this student copy of the PowerPoint as the images are a great recap of all concepts pertaining to this topic.

7.013 Spring 2005 Problem Set 2 - Genetics
Three pedigrees are presented for junior geneticists to interpret. Then, a double strand of DNA is printed for them to analyze. Hypothetical animal crosses are described, from which learners determine the genotypes and phenotypes of the offspring.

After learning to calculate probabilities for single examples of genetic crosses in a previous lecture, students are exposed to the concept that allele and genotype frequencies in a population remain in constant equilibrium. A reasonable grasp of math is necessary to comprehend this presentation.

Pregnancy, day 1
A health lesson presents all aspects of conception and pregnancy. Fourth through sixth-graders define terms associated with pregnancy, label a chart of a woman, and discuss how pregnancy occurs. Some excellent activities and a wonderful worksheet are included in this impressive plan.
4th - 6th Health 9 Views 20 Downloads
Students explore DNA, genes, chromosomes and the chemicals that make up DNA. They research Internet resources to develop their knowledge of DNA. They conduct an experiment to separate DNA from peas and create a poster that they can use to teach others about DNA.

Beyond Mendel's Laws of Inheritance
This PowerPoint jumps right into the details of unusual traits and how they are coded. The epistasis patterns in Labradors are used as a main example, and many instances of polygenic inheritance malfunctions are explained. All of this should grab your students' attention!

Facts of Life - Gender Determination
Why do Y chromosomes result in boys? This video explains that the default human being is female, but a sex-determining region, or SRY, on the Y chromosome is the single gene that tells the cells to produce a male before disappearing. It directs the embryo to develop male organs, produce sperm cells, and perform basic cell housekeeping.

Genome: A Tour and Genetic Disorder Brochure
Students use the Internet to gather information about genetics, then research a genetic disorder. In this biology lesson plan, students listen to an interview with a geneticist, watch an animation of "chromosome coiling", then research and create a brochure with information about a genetic disorder.
