Personalized medicine prevents many trial-and-error scenarios when time counts the most. Learn how gene expression and screening genomes improves health outcomes in cancer patients, those with auto-immune disorders, and more. An online...

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...

In this relationships and biodiversity worksheet, students investigate the relationships between 4 plants sample using 7 different tests. These include looking at structural characteristics of the plants, seeds and stems, using paper...

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...

If you've ever felt a little drained ... try converting some ATP to ADP! Science scholars perform one of life's most important reactions using a simulated lab workbench. The fun-to-use interactive allows pupils to control the reactants...

What is a proteasome? Like tiny trash compactors inside cells, proteasomes turn worn-out proteins into reusable amino acids! Explore the topic with a presentation and embedded simulations. The resource includes a teacher's reference and...

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.

Biotechnology is big! Introduce the uses of biotechnology to science scholars with a fascinating, fact-filled unit. The first installment in a series of four biotechnology units covers the role biotechnology plays in human and...

Roger Kornberg, the oldest son of two biochemists, won the 2006 Nobel Prize in Chemistry. Learn about Kornberg and his scientific research with an animation, videos, biography, and an applied problem-solving activity. A summary and...

Have you ever wondered why some people are lactose intolerant? Participants test simulated patients in a hands-on lab activity to find out! They learn about lactose intolerance by performing an experiment, analyzing data, and drawing...

How do genetics gurus know so much about gene expression? See traits materialize before your very eyes using a presentation with embedded simulations. Science scholars develop an understanding of the techniques used to follow the work of...

Many physicals include a blood glucose test, but what are doctors actually testing? Scholars graph and interpret blood glucose data, allowing them to observe the differences in lactase persistence and draw conclusions. They then connect...

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...

In this small intestine, pancreas, liver, and gall bladder worksheet, students fill in the blanks with information about these structures of digestion. Students research information about organ of the digestive system given.

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

In this biology worksheet, students identify and locate various vocabulary terms pertaining to types of proteins. There are 22 biology terms located in the word search.

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.
