Mitosis Cookies Activity
Reward biology learners for working hard in their mitosis lesson with a sweet snack at the end! They begin by twisting apart creme-filled cookies and using the icing as a cytoplasm. Colored candy sprinkles make up chromosome pairs, which...
Science Friday
Colorful Chromosomes
Everything is in the genes. Individuals observe 14 different traits of themselves. Using pipe cleaners and beads, the learners create models of a chromosome representing their traits. The class then compares and contrasts everyone's...

Pipe Cleaner Babies
Ever been told you have your father's eyes? How did it happen? Young biologists get a hands-on experience in meiotic gene expression with a fun pairs-based activity. Participants use pipe cleaner chromosomes with trait beads to make...

Genes Get Shuffled When Chromosomes Exchange Pieces
Some genes link to others that have implications for inheritance. A set of resources lead pupils through the history of this discovery. They explain how chromosomes recombine and which parts are more susceptible to this linkage....

Dragon Genetics ~ Independent Assortment and Genetic Linkage
Imagine a pair of dragons that produce offspring. What percentage of the hatchlings have wings and large antlers? An engaging activity draws genetics learners in, introduces them to alleles, meiosis, phenotypes, genotypes, and teaches...

A Chromosome Study
Study groups based on sizes of pairs. Pupils use images of chromosomes to create an organized pattern grouped into pairs and organized on size called a karyotype. Scholars create a second karyotype that contains a genetic disorder and...

Cell, Socks, and Sex
Donate old socks for science! Young biologists model mitosis and meiosis, using socks as chromosomes and a balloon as a nucleus. This ingenious idea for modeling cell division will be more memorable to your young biologists than any set...

You're My 'Karyo'-Type: Karyotype For Chromosomal Disorders
What's your type? Genetically speaking, of course! Immerse your class in the world of karyotypes through an insightful activity from the K20 Center. Scholars take on the role of genetic counselors to determine the karyotype of offspring...

Principles of Heredity
Students model traits on genes using colored paper and tongue depressors to represent chromosomes. In this heredity lesson plan, students use their "chromosome sticks" to understand chromosome pairs, genes, dominant traits, recessive...

Chromosomes
Young scholars explore genetics, chromosomes and DNA. In this genetics lesson students design a chromosome and identify a family tree through genetics.Â
Perkins School for the Blind
Chromosome Models- Karyotyping
Create your own karyotypes with clay in a kinesthetic genome activity. This tactile experience was created for visually impaired pupils, but can be used for all hands-on learners who are beginning to study chromosomes. The preparation...
