Young scientists demonstrate their creativity while completing several activities, to assess genetic variations and mutations. Instructors provide a list of options and scientists choose to write a comic strip, create a book,...

Based on current scientific knowledge, all cells come from preexisting cells. Scholars learn about cell division, cell replication, mitosis, meiosis, and more with a PowerPoint. It describes the differences between prokaryotes and...

Students interact with a video to explore the basis for the science of chromosomes. They perform a chromosomal analysis called a karyotype and explore how seemingly minute errors in chromosomes can lead to devastating illnesses.

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.

Fourth graders explore genetic disorders, which can be caused by a malfunction in a particular chromosome and how these can cause genetic mutation.

Students study how cancer cells mutate and affect cell division.  In this investigative lesson students view a PowerPoint presentation learn the seven warning signs of cancer. 

Students examine how living cells create new cells and how genetic mutations can cause disorders and be inherited.  In this genetic reproductionn lesson students create their own PowerPoint presentation. 

The main objective of this activity is to illustrate the variation that results from crossing-over during prophase I of meiosis. Other sources of variation from generation to generation are: (1) independent assortment (223 possible...

Pupils analyze gels to determine parentage in this lesson about scientific evidence, investigation, and DNA concepts. The lesson includes a pre-activity worksheet, a final individual assessment, and student handouts for in-class...

Understanding how chromosomes, DNA and genes all work together can be confusing. The author has explained how chromosomes fit into the picture in clear language.

This is an excellent PowerPoint presentation that explains what chromosomes are. Many slides are also accompanied by detailed notes.

This map from Access Excellence shows human chromosome pairs. The site includes a short description of chromosome structure, staining of chromosomes and karyotypes.

Find out about the chromosome karyotype and how that identifies a human as a human. [0:46]

If you want an interactive way to practice karyotyping, this is it. There are three patient histories and karyotypes to use in diagnosing human genetic disorders. There is enough information on comparing chromosomes to get you started.

Drag and match the chromosome pairs to organize this human karyotype profile.

This comprehensive study guide covers the main terms and concepts needed for a unit on human chromosomes and genes.

Try your hand at matching chromosomes to complete the karyotype in this simulation. Simulation contains karyotyping activity for three different patients and students can explore whether those patients have any genetic disorders.

Follow a series of chromosome problem scenarios to learn about several genetic disorders. Test your knowledge with a quiz at the end of the exercise.

A self paced tutorial covering chromosomal testing and the many types of conditions resulting from chromosome abnormalities.

This is a great lesson plan that combines Karoytypes and evolution. Students will recognize that the chromosomes of chimpanzees and humans are remarkably similar, then correlate that to their evolutionary relationship.

Read about the findings from the scientific group from the National Center for Human Genome Research, which published a modification to traditional karyotyping that permits rapid identification of chromosomal alterations.

This game has students matching pairs of chromosomes to determine if there are any extras, indicating Down Syndrome.

This site opens with an excellent introduction to Cytogenetics. Explore this site to learn about chromosomes, human karyotypes and more.

Great for a quick check of facts related to detection and common abnormalities. Use these for a test review.
