Seventh-graders come in to science class to find a file on their desks detailing a crime to be solved! As a demonstration, you simulate the restriction of DNA samples and separate them by electrophoresis. From the gel, learners can...

How can you tell the difference between endothermic and exothermic reactions? Chemistry scholars perform and observe two chemical reactions, measure the temperature throughout, then draw conclusions about changes in energy from their...

Students examine the characteristics of lactose and lactase.  In this enzyme lesson students study the lactose in milk and its rate of dissolution.

Students experiment with lactase to find out how milk sugar is broken down in the body. In this enzyme lesson, students use glucose strips to investigate the breakdown of lactose into glucose and galactose for milk digestion in the human...

Learners explore the effects of chemical reactions when cooking. Using the Internet, they research enzymes and then mix jello. They examine their results and test enzyme activity by adding pineapple to the jello. Finally, they test...

Students explore the basic process of natural selection and how people can manipulate that process today. The consequences of natural selection on daily life and the implications of evolutionary biology in basic and applied science is...

Students explain the importance and function of enzymes. They compare and contrast the processes of DNA replication and polymerase chain reactions. They practice using new vocabulary as well.

Students are allowed to strip away the cell walls of plants cells (using enzymes) and then observe the resulting spherical protoplasts (plant cells minus the cell wall). They see that plants cells indeed have a plasma membrane in...

How can you effectively provide detailed concepts of water properties to your high school class in a way they find exciting and challenging at the same time? By letting them play, of course! Through a variety of...

Students will illustrate how restriction enzymes work by piecing together parts of a puzzle. Then they apply this knowledge to help them analyze genetic evidence from the scene of a crime as well as to help them comprehend how a DNA...

Students engineer new organisms using biotechnology. In small groups, they write procedures, list benefits and drawbacks, and explain how their new organism might affect the environment. After creating their new organisms, they present...

Let's get a closer look at DNA and other molecular structures. The first lesson in the series of four introduces a variety of imagining techniques that engineers and scientists use to visualize molecular structures. The resource presents...

In this science worksheet, learners answer 14 questions about respiration. For example, "Cellular Respiration starts off with..."

Students construct DNA fingerprints. In this genetics lesson, students watch an on-line gel electrophoresis animation, then they work in groups to use a restriction map to create a restriction enzyme and use that to arrange a DNA...

In this photosynthesis, disease and Immune System worksheet, students fill in the blanks with key terms to complete sentences about the transfer of energy from the sun to plants, enzymes as catalysts in reactions, homeostasis, the immune...

Students read about how forensic entomologists use maggots to solve murders. In this forensic science lesson, students read an article and answer questions. They go to different websites about evidence and fingerprinting. 

Students identify DNA in a crime scenario. In this DNA lesson plan, students perform paper chromatography and compare it against the pens of various suspects.

Students work with tools and techniques used in genetic engineering. They dissect a sample into fragments of DNA using restriction enzymes, sometimes called "molecular scissors". They sort these fragments, measure and analyze them according

Ninth graders examine the structure and function of biomolecules. In this food molecule instructional activity, 9th graders will examine various  types of biomolecules such as  carbohydrates, lipids, proteins, and nucleic...

Culminate a bioethics unit with the implementation of a lesson that incorporates the Socratic method to encourage class feedback and participation. Pupils participate in a discussion on bioethics and morality, complete a...

High schoolers conduct a variety of experiments to explore gel electrophoresis. In this biology lesson, explain how this process separate DNA and RNA. They discuss the practical applications of this method.

Students conduct a variety of experiments to explore protein. In this biology lesson, students solve a mystery by testing for the presence of glucose, protein starch and triglycerides. They explain how DNA transcription and translation...

Students observe demonstrations to show factors that affect rates of chemical reactions. In this rates of chemical reactions lesson plan, students investigate how catalysts, reactant concentrations, temperature and surface area affect...

Students 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...
