Students examine human health by identifying dangerous pesticides. For this agriculture lesson, students research the food production system in the United States and discuss dangers such as pesticides, chemicals and insecticides which...

Lab groups fill a section of dialysis tubing with glucose and starch solutions and suspend it in a water bath. They use iodine as a starch indicator and a glucose test strip to find out if either of the materials crossed the selectively...

Students compare their unknown serum against a set of known serum standards and determine the animal source of their serum. They write a lab report to communicate their results.

You will need a photovoltaic system and monitor at your school in order to obtain all of the data required to thoroughly implement this lesson. Your class monitors daily temperature and insolation amounts over a two week span of time....

Students role-play a scenario in which a car crash patient is inadvertently given the wrong blood type during a transfusion. They perform blood typing and explore the genetics behind ABO and RH blood types using simulated blood.

After your biologists have learned about transcription, translation, and gene regulation, they work in a small group to create a poster of a system that serves as an analogy of the gene regulation process. They share their creations with...

Students are guided through a process in which three questions are addressed by retrieving beta hemoglobin sequences from online databases, and using online tools to compare those sequences in student-selected animals.

Students construct cladograms (evolutionary trees), showing how shared derived characters can be used to reveal degrees of relationship. They interpret and analyze cladograms, and determine where unclassified vertebrates would fit on a...

Students model a sarcomere's action, they gain a kinesthetic and visual understanding of muscle contraction. They use this exercise stimulates the production of myosin and actin. Students use two colors of clay, make a "sandwich" of...

Students spend the lesson reviewing for their Genetics exam. In groups, they compare and contrast the structures of DNA and RNA and discuss how DNA can cause mutations. To end the lesson, they share their knowledge on the contributions...

Pupils actively engage in the careful analysis of chromosome banding patterns and identify examples of inversion in homologous chromosomes.

High schoolers develop a concept of the relative size of objects in the nanoscale. They complete an internet assignment using the website,"Scaling the Universe to Your Desktop". Using analogies to common objects they get an...

Young scholars explore the classification system of organisms: taxonomy. They examine prepared slides of Protozoans and record information on a Taxonomy Recording Sheet. Two additional classifying activities are also included in this...

Students complete a worksheet on solutes in chemistry. They are given an equation in order to find the total mass solution, molarity, and molality.

Students see how patterns can reveal events of the past, thereby merging elements of both experimental and historical science.

[Free Registration/Login may be required to access all resource tools.] Overview of the central dogma of molecular biology.

The main objective for this exercise is to enhance your study of the properties and structures of biological molecules with modern computer graphics. Rather than passively viewing illustrations of molecular structure as they occur in...

Explore cell and molecular biology online. Investigate career issues, message boards, and articles.

Take this interactive, multiple-choice quiz over the biochemical processes of life, then review your score and any missed questions at the end.

Take this interactive quiz over Mendelian and molecular genetics, then review your score and any missed questions at the end.

Take an interactive quiz over biochemistry and organic chemistry. After completing the quiz, check your score, and then revisit any incorrect question for further review.

This site from the University of Massachusetts links to downloadable freeware (Rasmol and CHIME) which are required to view 3-D images common on organic chemistry tutorials.

Endocytosis enables cells to absorb extracellular nutrients that are needed for their survival. In receptor-mediated endocytosis, a protein receptor on the cell membrane binds to a nutrient molecule and facilitates its absorption through...

A fantastic interactive laboratory in which transgenic flies are created and used to study circadian rhythms. Excellent supporting information and resources for teachers and students.
