This exam touches upon every topic within the typical first year biology course.. A broad variety of question styles give high schoolers every opportunity to show what they know. Why start from scratch when a comprehensive final exam is...

Students build DNA strands and practice base pairing rules using an interactive website in this technology-based lesson for a high school science class. This lesson includes links to the interactive website, a worksheet, and a video...

Tenth graders explore DNA using online tutorial. They perform their own DNA extraction from a clove of garlic and identify the key components of DNA.

Students extract their own DNA from cheek cells. In this biology instructional activity, students explain the replication process. They identify the structure and composition of DNA.

Students study genetics and heredity. They explore the structure of DNA and genes through a series of activities that includes watching videos, conducting online research, and making vocabulary books. They investigate DNA, genetics,...

Students investigate the progression of discoveries that have led to the genetics knowledge that scientists currently have. They determine how genetic experiments disproved previous theories on inheritance.

Tenth graders work with a partner, and copies of the attached worksheet "Amino Acid Codon Table" They discuss ways an organism, obtains and uses proteins. Students view a teacher prepared DNA strand banner, and record the complementary...

How do changes in DNA affect an organism? Scholars explore chromosomes, genes, DNA, and mutations by modeling the DNA of a strawberry. They build a DNA model, then manipulate it to show how changing the genes transforms the strawberry...

An exciting activity has scholars use cell parts to build bacteria through cooperation with other groups. Each group has some of the cell parts needed, but they must trade with other groups to be able to fulfill their function as a...

How do genetic mutations within a population lead to future variations? Provide your class with the resources to answer this question and more upon completing an activity on natural selection. The entire class participates in a...

Students extract DNA from split peas. In this biology instructional activity, students research how chromatin form into chromosomes. They draw the stages and present their work in class.

Five pages provide thorough coverage of three protozoans: euglena, amoebae, and paramecia. For each, junior biologists read factual text, label the organism, and write answers to several questions. This neatly organized assignment is...

Pupils write an essay on the basic steps of the DNA replication process accurately enough to show a complete understanding of the subject. Finally, student correctly identify the polarity of the template strand and match the correct base...

High schoolers use their knowledge of DNA fingerprinting to evaluate the use fingerprints in courts, and will address the ethics of establishing a national database of fingerprints.

Students explore DNA fingerprinting. Students discover how DNA fingerprinting is done and judge the validity. They evaluate the use of certain prints in courts and address the ethics of establishing a national database of fingerprpints.

Learners use the exercise as a prelude to a "wet" lab or as a substitute for such a lab. It correlates well with colony transformation labs. This lab is recommended for students what have difficulty with the abstractions that genetic...

Young scholars examine a method biologists use to try to determine relationships. They examine how amino acid sequences have been determined for a number of proteins, and how scientists can make inferences about DNA based on the amino...

Students investigate how mutations lead to changes in cell structure and function. They construct an oligonucleotide, identify a protein sequence, design a step-by-step mechanism of how they think cells repair damaged DNA, and prepare...

Learners review the structure and function of DNA, genes, and chromosomes and are engaged by a demonstration illustrating the relative size of DNA, genes and chromosomes. They also describe through analogy and model the structure and...

Students isolate DNA from kiwi cells, spool DNA from a kiwi, describe role of the DNA and genes, and explain how knowledge of DNA and genes can be used in genetically modifying foods.

Students use a DNA strand to identify the component parts. They discuss an RNA molecule, protein fragments, and nucleotides. They explore how the order of nucleotides determines the order of amino acids in proteins.

Students describe a spool of light colored thread that the teacher holds in his/her hands. They are asked what substances (cotton and wood) are present and what structures (thread and spool) are present. The teacher conclude that the...

Students simulate gene splicing by examining bacteria. They create a bacterial DNA into which they insert the human DNA (gene) that codes for growth hormone. They cut the sites of the enzyme to study how the human DNA can be joined to...

Students examine the principles of electrophoresis. They evaluate both the agarose and polyacrylamide system of molecular separation. In order to bring the concepts of genetics and evolution full circle from DNA to protein, students...
