You can access the problems below via the Load Homework dialogue in the File menu of the Virtual Lab. They have been organized by concept and ranked by difficulty (A ranking of 1 denotes an easier problem; 5 is more challenging). Word files for these problems are provided so that you may edit and distribute the assignments in your classroom. The following types of problems can be found:Strong and Weak Acid and Base Problems, Determination of the pH Scale by the Method of Successive Dilutions, Standardization of NaOH: Acid Base Titration, Determining the pKa and concentration ratio of a protein in solution, Unknown Acid and Base problem, Creating a Buffer Solution, DNA - Dye Binding: Equilibrium and Buffer Solutions.

This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they see how DNA is used to solve crimes against animals. The activity starts with an introduction to George Amato, an AMNH scientist who sometimes helps the U.S. government solve mysteries. In a three-part online slide show, students see how Amato earned the title "DNA Detective" in 1993 when he helped the U.S. Fish and Wildlife Service catch someone trying to sneak protected reptile skin into the United States. Then students are challenged to Crack the Code, an online game in which they play DNA detective and determine which of a collection of handbags, clothing, figurines, and other items are made from protected species.

"Normally, an animal gets half its DNA from its mother and half from its father. But Dolly had three mothers: one mother gave Dolly her DNA; one supplied an egg; and the third, her surrogate mother, gave birth to her. Dolly is an identical twin of the mother who gave her her DNA. But Dolly is six years younger."This kid-friendly Web page helps kids understand how and why Dolly was cloned, and understand the potential benefits of cloning as well as the controversy it raises.

This class analyzes complex biological processes from the molecular, cellular, extracellular, and organ levels of hierarchy. Emphasis is placed on the basic biochemical and biophysical principles that govern these processes. Examples of processes to be studied include chemotaxis, the fixation of nitrogen into organic biological molecules, growth factor and hormone mediated signaling cascades, and signaling cascades leading to cell death in response to DNA damage. In each case, the availability of a resource, or the presence of a stimulus, results in some biochemical pathways being turned on while others are turned off. The course examines the dynamic aspects of these processes and details how biochemical mechanistic themes impinge on molecular/cellular/tissue/organ-level functions. Chemical and quantitative views of the interplay of multiple pathways as biological networks are emphasized. Student work will culminate in the preparation of a unique grant application in an area of biological networks.

The homeobox genes that define the basic body plan of mice and fruit flies are illustrated in this graphic from The Human Evolution Coloring Book by Adrienne Zihlman. The accompanying article describes how these genes act as molecular architects in all animal species.

This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they take a look at genetics and DNA research with six AMNH scientists' journals. The Humpback Whale Journal takes kids to Madagascar to meet this endangered species. The Spotted Owl Journal takes kids to California for a look at these birds who are at risk because their forest homes are being cut down. The Sumatran Tiger Journal takes kids to Indonesia for a look at this genetically unique tiger. The Ruffed Lemur Journal also takes kids to Madagascar, but this time they venture inland to meet the endangered primate. The Pacu Journal takes kids to Brazil to meet this vegetarian relative of the meat-eating piranha. The St. Vincent Parrot Journal takes kids to the West Indies to meet the rare, colorful birds that are further at risk because of smuggling.

Becoming Human is an interactive documentary experience that tells the story of human origins. Multimedia, research and scholarship are presented to promote greater understanding of the course of human evolution. This site includes classroom materials, subject-designed exercises, games and activities to help make connections between the concepts that are presented and student learning. PDF versions of the resources may be downloaded from the site.

This is a comprehensive textbook covering life functions that are ultimately interpretable in chemical terms, as chemistry is the logic of biological phenomena.

" The course, which spans two thirds of a semester, provides students with a research-inspired laboratory experience that introduces standard biochemical techniques in the context of investigating a current and exciting research topic, acquired resistance to the cancer drug Gleevec. Techniques include protein expression, purification, and gel analysis, PCR, site-directed mutagenesis, kinase activity assays, and protein structure viewing. This class is part of the new laboratory curriculum in the MIT Department of Chemistry. Undergraduate Research-Inspired Experimental Chemistry Alternatives (URIECA) introduces students to cutting edge research topics in a modular format. Acknowledgments Development of this course was funded through an HHMI Professors grant to Professor Catherine L. Drennan."

This educational journal article addresses the implementation of bioinformatics in the classroom. The author explains how bioinformatics could play a key role for science students pursuing higher education, foster inquiry learning of content that has often been taught in a dry manner, provide the thread that ties classes together, improve biology teaching, enhance the learning of biotech issues and ethics, expose students to real-world science, and significantly help to reform biology teaching and improve learning. The article includes links to bioinformatics resources, information about how to get involved in bioinformatics, and a glossary of terms.

The Biology course is a first-year course in biology at the high school level and involves the scientific study of living organisms. The course considers the interactions among the vast number of organisms that inhabit planet Earth. It presents the basic form and function of these organisms, from cells to organ systems, from simple viruses to complex humans. It delves into interactions between organisms, and between an organism and its environment. It also looks into how biotechnology is used to improve our health and daily lives.

- Understand the form and function of microorganisms
- Understand the form and function of plants
- Understand the form and function of animals
- Understand the workings of human biological systems
- Understand biology as it relates to the Earth's environment

CK-12 Biology is a high school FlexBook covering cell biology, genetics, evolution, ecology, microorganisms, fungi, plants, invertebrates, vertebrates, and physiology.

CK-12 Biology Workbook complements its CK-12 Biology book.

This site contains user-friendly tools to launch DNA database searches, statistical analyses, and population modeling from a centralized workspace. Educational databases support investigations of an Alu insertion polymorphism on human chromosome 16 and single nucleotide polymorphisms (SNPs) in the human mitochondrial control region.
