After initial exposure to a carcinogen, a cancer diagnosis often takes more than a decade due to the slow buildup of mutated cells in the body. Scholars learn about the biology of cancer with a worksheet and discussion questions. They...

Intrigue the class by completing a lesson on meiosis, filled with challenging and insightful activities to spark the interest of every person in the room. Each member of the class learns about genetic disorders due to faulty meiosis, and...

Students investigate how cells determine which genes will be expressed and which will be silent. In this genetics instructional activity, students use on-line resources to complete a worksheet and gather information about gene...

A pinch of adenine, a dash of thymine and ta-da, you have life! Well, it's not quite that simple, but through this series of activities and experiments young scientists learn about the structure of DNA and how it contains the recipe...

Students explore chromosome karyotyping. In this chromosome karyotyping lesson plan, students use a chromosome kit to explore chromosome syndromes and disorders. They also produce a large model of a cell with chromosome to simulate cell...

Does day one of meiosis in your biology classroom make you wanna split? Get the class off to a great start using this attractive and thoughtfully worded slideshow. In addition to explaining what happens during each step of meiosis,...

Wow! A very detailed slideshow covers complex topics of genome research methods. This is advanced and relevant to the highest level of school biology. Excellent resource if you wish to expose your class to scientific methods and...

Students explore DNA microarrays. In this genetics lesson, students model DNA microarrays that are used by scientists. Students work to determine levels of breast cancer genes in patients. They will determine the treatment required based...

Students review what they can recall about viruses. They are explained that they are going to work on a project in which they suggest a useful purpose of a virus. Students use print research materials and the Internet to add to their...

Learners 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...

What is in that double helix? Explain intricate concepts with a variety of creative activities in a lesson that incorporates multiple steps to cover DNA structure, nucleic acids, and proteins. Pupils explore the history of DNA structure,...

In this science worksheet, learners answer 13 multiple-choice questions about mitosis and meiosis. For example, "Interphase is defined as..."

Students construct and manipulate models of mitosis and meiosis and compare/contrast them. They create the models using index cards and yarn, interpret diagrams and photographs, and summarize written descriptions.

Eighth graders are able to define meiosis. They are able to compare and contrast meiosis and mitosis. Students are able to state the phases of meiosis. They complete a K-W-L chart on meiosis and mitosis. Students talk about meiosis...

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,...

High schoolers research online to answer and develop questions about immune system, create Powerpoint presentation to share information with classmates, and assimilate information into pictorial and/or graphical description of immune...

A complete, student-led lesson on cell structure, cell division, and cancer growth. Students work their way through illustrations and animated tutorials, and answer review questions along the way. There is a self-checking quiz at the end...

Chromosomes carry genetic information in a molecule called DNA. A type of cell division called mitosis ensures that when a cell divides each new cell produced has the same genetic information.

Cell division is the only way single-celled organisms can reproduce. Learn more about cell division and explore the phases, checkpoints, and protein regulators of the cell cycle in this interactive. Find out how mutated versions of these...

Article takes a look at how cancer develops and what's wrong with cancer cells. Also, delves into how abnormal forms of cell cycle regulators can contribute to cancer.

Chromosomes carry genetic information in a molecule called DNA. A type of cell division called mitosis ensures that when a cell divides each new cell produced has the same genetic information. Links to a video and a test are provided.

Review, identify, and describe the important steps in the cell reproduction of whitefish, onion root, and lily anther, and quiz yourself on the similarities and differences between mitosis and meiosis. A "Cell Division Construction Kit"...

This animation from NOVA: "Battle in the War on Cancer: Breast Cancer" describes how oncogenes cause cancer and how cancerous cells can spread throughout the body.

Resource provides a holistic and complete meiosis lesson with illustrations, animations, glossary, and links. Extremely detailed and helpful site.
