Students study why corn is a biodegradable, renewable resource.  In this ethanol lesson students build models and observe a chemical reaction.

Twelfth graders explore the usage of alcohol fuel. In this Current Events lesson, 12th graders research the issue of using this type of energy.  Students complete a worksheet on their research. 

Students explain the processes for separating DNA from tissue and separating complex mixtures.  In this exploratory lesson plan students complete a lab where they extract DNA.  

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 compare the different rates of reaction between an apple covered with vitamin C and an apple with no vitamin C. They compare the different rates of reaction between an apple placed in the sun and one not exposed to the sun. ...

High schoolers explain the process of polymerization. In this chemistry lesson plan, students produce carboxylesterase in the lab. They test its effectiveness in removing the by-product odor.

Learners examine how carnivorous plants get their nutrients from animals.  In this food web lesson students examine how the plants attract their prey and are given many onilne sources to research.

The Henderson-Hasselbalch equation combined logarithmic terms with the application of carbonic acid as a buffer solution. Scholars learn investigate equation and its applications through hands-on experiments. They collect data and...

Students model recombination in DNA. They color the DNA sample and cut it out. Students use their "restriction enzymes" to cut the DNA into specific fragments. They separate the fragments using the "gel electrotrophoresis." Students...

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...

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...

The fifth lesson in the six part series introduces units of energy including calories, Calories, and joules. Scholars determine the energy released when eating a snack and during activity.

Scholars learn about heat release in phase changes. They perform calculations as they compare and contrast a science fiction passage and a home heating application.

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...

Twelfth graders simulate a DNA fragment running through a gel electrophoresis in a class activity. Students work in teams as a DNA sample with each person on the team representing a fragment that moves through the gel at a specific speed.

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

Students use this laboratory exercise, restriction enzymes to recognize a four-, six-, and eight-nucleotide sequence. Assuming that the four component nucleotides (A, C, T, G) are distributed randomly within a DNA molecule, then any...

Students applied various mathematical analyses to interpret their data. By using the resulting DNA fragment patterns from several enzymes students established a possible evolutionary relationship among the mice.

Students identify the steps in a gel electrophoresis experiment and describe the role of enzymes. They examine the relationship between fragment size and migration rate in a gel. They view DNA fragments as well.

High schoolers explore the process of chemosynthesis and relate it to the biological communities in cold seeps. In this biochemistry instructional activity students interpret analyses of enzyme activity and draw inferences about...

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...

Fifth graders make cheese using two different methods. In this cheese making instructional activity, 5th graders make rennet cultured cheese following the step by step directions. They also make cheese using a genetically engineered...

Students investigate the use of restriction enzymes to recognize a four-, six-, and eight-nucleotide sequence. They utilize restrictive endonucleases to cut Thymus DNA and compare results by viewing the DNA fragments on Agarose Gel...
