KARYOTYPE ALTERNATIVES
Students comprehend that karyotyping is a process in which chromosomes are cut from an enlarged picture and arranged in decreasing order of size. The cells to be viewed are first chemically treated to increase the number of dividing...
Curated OER
The Spanish Omelet
Students use analogies to show the relationships among cell, nucleus, genes, chromosome, ribosome, replication, mitosis, transcription, translation, DNA, RNA, amino acids and proteins, genotype, phenotype, and genetics vs. environmental...
Curated OER
Chromosomes and Genetic Mapping
Students are introduced to mapping by crossover frequency. Genes travel as packaged trains on chromosomes. They use this experiment, genetic mapping assignment, that allow students to quickly complete the assignment and yet examine the...
Curated OER
Heredity Mix 'n Match
Students randomly select jelly beans that represent genes for several human traits such as tongue-rolling ability and eye color. Then, working in pairs (preferably of mixed gender), students randomly choose new pairs of jelly beans from...

How Can You Predict the Characteristics of an Unborn Baby?
Students compare three sets of unlabeled human chromosomes and gather related data, trace chromosomes to pair them, and make observations about them.
Curated OER
Cells: Structures and Processes
Students explore the basic unit of life, the cell in this nine lessons unit. The cell structure of animal and plant cell functions and how they affect our world are probed in this unit.

DNA Extraction From Onion
Students extract DNA from an onion using household equipment and supplies.
Curated OER
How Do Organisms Reproduce
Learners examine the difference between mitosis and meiosis, and describe the steps involved in meiosis and the significance of each step. They create a diploid nucleus containing two pairs of chromosomes using clay.
Curated OER
MITOSIS
Tenth graders examine the process of mitosis on a laser disc. They examine mitosis in an onion utilizing the microscope.
Curated OER
Genetics: Integrated with History and Art
Young scholars work cooperatively in pairing chromosomes, created statistical genetic babies using the face lab, constructed a color DNA booklet and demonstrated mitosis in a flip book.
Curated OER
Cell Division: Frog Egg Division Observation and Modeling
Students create and test a hypothesis about cell division. After observation of Frog Egg cell division, students write obervations and refine process and hypothesis. The use of scientific method, group work and inquiry are fostered by...
Curated OER
Meiosis
Using yarn and chenille stems, lab groups collaborate to model mitosis and meiosis. Brief background information and a vaguely written procedure comprise this outline. More instruction needs to be provided to learners about cell division...

Lesson 5: Untangling DNA
Students extract DNA from split peas. In this biology lesson, students research how chromatin form into chromosomes. They draw the stages and present their work in class.
Curated OER
Biotechnology
The intricate details of DNA structure and the double helix are covered in this presentation. Many details about chemical behavior are also explained which will help your students review DNA. Many of the slides are summaries and the 37...

Born of Blood
Young scholars define attributes of human chromosomes and match them to make a human karyotype. For this investigative lesson students demonstrate how traits are encoded in genes found on chromosomes.
Curated OER
Born of Blood
Eighth graders use a large Punnett Square and infer how genes determine blood types. In this blood type lesson students predict blood types and demonstrate how Punnett Squares are related to genes and chromosomes.
Curated OER
Born of Blood: Inheritance of Blood Types
Students examine inheritance of blood types. In the chromosome lesson, students create a model of chromosome and predict the blood type of offspring.
Curated OER
X or Y- Does it Make a Difference?
Students examine the X and Y chromosomes. In this research lesson, students use the 5E lesson model as they read articles about human chromosomes then discuss their findings and opinions.
