Students build chromosome models using popsicle sticks. In this biology lesson plan, students simulate the Law of Independent Assortment. They use Punnett squares to predict the resulting genotype and phenotype.
Students view a video on DNA. They discuss mitosis, meiosis and fertilization. They use strips of paper to simulate fertilization and analyze the genotype and phenotype of the combined chromosomes.
Fourth graders explore genetic disorders, which can be caused by a malfunction in a particular chromosome and how these can cause genetic mutation.
Students examine the concept of homology by observing their shoes and those of their classmates. They summarize the observations of everyone's shoes relating it to chromosomes in cells. They share their observations with the class.
Students identify and illustrate how changes in DNA cause mutations and evaluate the significance of these changes. They illustrate a chromosomal mutation such as duplication, deletion, inversion, and translocation.
Students explore genetics. They discuss how chromosomes and/or genes are regulated during the life of an organism. In a lab setting, students compare and contrast the genomic regulation of prokaryotic and eukaryotic cells using manipulatives. They complete a fertilization lab and discuss the synthesis of DNA.
Students discuss the importance of reproduction of cells. They identify and describe the stages of Mitosis. They discover what happens to chromosomes and DNA during reproduction.
In this biology activity, students complete a concept map on different types of mutations. They fill in 7 blanks with the correct word from the list.
Seventh graders discuss traits, traits that are inherited and how genes and chromosomes carry the code for traits. They research genetic disorders and their link to chromosome abnormalites and write a report on their findings. which include complete and thorough
Tenth graders investigate the chemical composition of DNA and RNA and how they work together to synthesize protein. They discover genetic codes, gene chromosome theory, and how the environment influences our appearance.
What do Ninja Turtles and Spiderman have in common? Hollywood has displayed them as the results of mutation. Biology whizzes take a look at real mutations in fruit flies, and then learn the difference between gene mutation and chromosomal mutation. They survey different meiosis errors resulting in nondisjunction, deletion, inversion, duplication, or translation of chromosomes. They view male and female human karyotypes. This comprehensive presentation will leave your learners looking for more!
Students study chromosomes and how molecular half life affects them.  For this chromosome lesson students complete several lab activities on calculating half life, and cracking alkanes. 
In this chromosome worksheet, students calculate percentage of recombination and the map distance between the two linked genes. This worksheet has 3 problems to solve.
These aren't the type of jeans you can buy at a local store! Help your class understand what determines if you're a girl or a boy. Show this cartoon representation of how a male and a female's chromosomes shuffle, divide, and recombine to create a baby. This video is part three of four video series.
Do you know how many chromosomes humans have? Do you know how many of those chromosomes we share with the chimpanzee? A perfect introduction to DNA for your middle schoolers, this video uses a ton of visuals to clearly illustrate the components of DNA. Part one of four.
If humans share over 99% of the same chromosomes, how are we different? There are 10 million SNPs in the human genome, accounting for most of our genetic differences. Watch this short clip to introduce your learners to SNPs, or single nucleotide polymorphisms. Part two of four.
Begin looking at reproduction by contrasting sexual reproduction with asexual reproduction. Sexual reproduction gives us genetic variation as meiosis creates brand new chromosomes through cross over. Male and female anatomy is covered, as well as menstruation and fertilization. The video unfortunately cuts out right when development of an embryo is beginning, but a lot is covered in the entirety of this clip.
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. Two activities are suggested to follow the video. In the first, learners review meiosis online. In the second, they participate in a simulation where they must develop a policy for the fairness of Olympic sports with regard to gender. This fascinating topic is sure to hold the interest of your young geneticists!
Sal from the Khan Academy draws an example of sexual reproduction and the chromosomes that come together from each gamete. Mitosis is also explained about halfway through the video, eventually showing differentiation and meiosis. Give your learners a cyclical view of how mitosis and meiosis work to create a new person!
Demonstrate the cell division and phases of meiosis by showing this video clip. An animated cell splits as chromosomes line up and are pulled apart by spindles. Help your young biologists see just how meiosis works.
