In this DNA: structure and replication worksheet, learners fill in the blanks about the structure of DNA and replication of DNA. Students sketch several diagrams of DNA at different stages.

Multiple choice, fill-in-the-blank, short answer, and matching questions are all here in a multi-page worksheet or quiz. While the formatting leaves a little to be desired, it would take just a few minutes to change the handout into a...

Learners define attributes of human chromosomes and match them to make a human karyotype.  In this investigative lesson plan students demonstrate how traits are encoded in genes found on chromosomes. 

Three steps are needed to extract DNA from learners' inner cheek cells. The procedure and reasons for each step are explained. As enzymes work on the cells, a series of questions are answered regarding the structure of the DNA molecule....

High schoolers plot particle sizes of common airborne materials on a log scale. They read an article on particle size and its relationship to the ability to pass through the lungs, into the bloodstream, and eventually into the cells...

Students identify the different parts of the nervous system. For this biology lesson, students research methods to diagnose and cure neurological disorders. They present their report to class.

Students conduct an experiment comparing human cells to chicken cells. In this cells lesson plan, students conduct an experiment to see how nutrition moves through cells and how to better take care of their bodies.

Students idenitfy that cancer is a growth of mutated cells and that cancer cells are only one type of cell that causes disease in our body. They also identify that all eukaryotic cells contain a nucleus, cytoskeleton, and a cell...

Tenth graders work on a project about cellular biology and genetics. In this biology lesson, 10th graders research about the assigned human body system and genetic disorders that affect it. They create a multimedia presentation and...

Students observe their own epithelial cells from the inside linings of their cheeks using DigiScope technology. They prepare a slide with both onion cells and epithelial cells and make an illustrated booklet for a PowerPoint presentation...

Did you know that meat tenderizers contain DNA cutting enzimes? Did you know that you can isolate your own DNA? Or the DNA of fruit? Explore with your learners the DNA world with a series of experiments using readily available materials...

In this chemistry of food worksheet, students complete 20 various types of questions related to food and nutrition. First, they complete a crossword puzzle with vocabulary terms. Then, students use the figure shown to write the...

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.

Ninth graders discover where their physical appearance and personality traits come from. In this genetics lesson, 9th graders learn about cells, chromosomes, DNA and genes. Students discover where genes come from as well as dominant and...

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.

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. 

Students observe their own DNA. In this DNA lesson, students learn the simple method of DNA extraction and explain why DNA extraction is important to scientists.

Students study the basic function of DNA and then extract it from strawberries. In this DNA extraction lesson students examine DNA and see why the extraction of it is so important to scientists. 

Students explain how the components of a cell operate as a system. Students examine a bicycle and find out if parts were arranged differently, could the system still be carried out. They look at cells as well and see what function they...

In this extremophiles non-fiction reading worksheet, students read a two page selection that describes the organisms known as extremophiles. They answer 10 questions based on the selection which include true or false, short answer, and...

Students record their blood types on a class graph and calculate the potential number of blood donors for each group.

In this cell division worksheet, students review the steps involved in a human somatic cell, from interphase to mitosis, to cytokinesis. This worksheet has 21 fill in the blank statements.

Students examine inheritance of blood types.  In the chromosome lesson, students create a model of chromosome and predict the blood type of offspring.
