Students complete a study guide using a website which is an animated primer on DNA, genes, and heredity. The Web site is organized around key concepts. The web links and study guide are included.

Students review what they already know about DNA. After reading an article, they discover a new technique to map the course of evolution. In groups, they create ways to present this material to younger children and research DNA's uses.

Students navigate through information about scientists who contributed to our understanding of DNA. In this interactive lesson plan, students gain historical understanding of scientists through a web-based timeline. They complete a...

Students investigate different purposes for manipulating DNA. After reviewing the structure and functions of DNA, students explore topics related to the use or manipulation of DNA and the potential benefits and problems, later making a...

Young scholars describe the structure of the double helix, explain how DNA copies itself, and recognize that the sequence of DNA is what makes each individual unique.

Students study the controversy surrounding the proposed Frederick Douglass Circle monument in Central Park. They review the notion of historical inaccuracy by reading and discussing the article, "In Douglass Tribute, Slave Folklore and...

Students formulate a hypothesis regarding the validity of the current status of the Arizona Hedgehog cactus as a distinct variety of cactus. They design a procedure to isolate DNA from the tissue of plants, given a list of chemicals and...

Students explore and discuss genetics stories and answer questions about genetic outcomes of offspring. For this genetics lesson, students read genetics stories on a web site. Students use a chart to answer questions regarding the...

Students summarize their classmates' presentation in class. In this biology lesson, students create a graphic organizer based on concepts presented. They discuss and share their organizer.

Learners create a model of DNA and relate it to the differences between individual people in their nitrogen base sequences. They analyze a crime scenario in which they perform several different types of tests.

A single page provides you with lecture notes for your lesson plan on hydrolysis. Introduce your chemistry class to Bronsted-Lowry theory by explaining the hydrolysis of acidic cations and basic anions. Show them how the resulting pH can...

In this chemistry chapter review worksheet, students examine their knowledge of equilibrium, Brønsted acid, and pH value as they respond to 25 short answer questions.

One of the most recognizable commercial melodies was written in 1977, and led to gastronomical relief around the world. Scholars use Alka Seltzer tablets to measure reactants and calculate the chemical equation for the reaction of NaHCO3...

In this science worksheet, students examine the safety labels that are displayed in the laboratory and then are expected to complete the homework questions.

Students investigate nutrient cycling in a simplified desktop ecosystem involving aquarium and hydro-ponically grown plants. They set up an aquarium with 10 gallons of water at least a week before the lab is planned and place...

Eighth graders explain how protein is made in the cell. For this biology lesson, 8th graders translate RNA and DNA using an internet database. They determine the thief based on evidence collected.

For this equilibrium worksheet, students answer 8 multiple choice questions but need to solve the problems in order to determine the answers. They include determining the concentrations of ions as well as the pH of solutions.

In this how HIV infects cells worksheet, students read the given information about how HIV infects cells. Students explain the role of various structures in HIV infection. Students design a drug that might slow the rate of cellular...

For this chemical reactions worksheet, students determine if solutions are acidic, basic, or neutral. Students give reactions' molecular equations and ionic equations. This worksheet has 14 problems to solve.

In this chemical reactions worksheet, students answer follow up questions to a lab where they were observing chemical changes in reactions after mixing products such as hydrochloric acid and sodium bicarbonate. They answer six questions...

Students determine the most appropriate site for a car wash, based on each site's soil characteristics (chemical, physical) and topographic features. They perform an experiment to determine the changes to three different soil types when...

In this acid-base worksheet, students calculate the pH of given solutions and determine if given solutions are acids, bases, or neutral. This worksheet has 3 graphic organizers and 4 problems to solve.

Students test the acidity of unknown solutions. They use this information to make inferences from data given from recorded rainfall records to identify areas that receive the most acid rain.
