On this stoichiometry worksheet students will be balancing chemical equations. After the equations are balanced, students will be conducting calculations to solve for grams, moles, and limiting reactants.

This exam covers every topic in a typical first-year biology course. A wide variety of question styles gives high schoolers every opportunity to show what they know. Why start from scratch when a comprehensive final exam is easily...

The New York Regents High School Examinations are comprehensive and include various question formats, including multiple choice and graph analysis. This particular version, the 2008 Living Environment exam, surveys a variety of topics....

The 2005 version of the Regents High School Examination in ecology is as comprehensive as previous years' exams. It consists of 40 multiple-choice questions on topics ranging from the structure of DNA to interactions within an ecosystem....

The living environment, from the interior of a cell to the complex relationships among populations, is queried in this final examination. Learners examine air pollution maps, cell diagrams, population graphs, and drawings of cells. They...

A complete study of population ecology is covered by this worksheet. Biology or ecology learners answer questions and interpret population graphs. This can be used as the intended guided notes worksheet or assigned as homework.

Learners work in small groups with a small set of 8 nuts and 5 bolts to assemble into combinations of 1 nut: 1 bolt, and 2 nuts: 1 bolt. They explore the outcome and discuss. Then a student mixes two clear, colorless solutions together...

Students sketch the graph of 4 functions and define the domain and range of each.

Twelfth graders problem solve limit/function value situations. They solve the problems using a graphing calculator, which allows them to see the function's graph, and infer the function value and limit from the graph.

In this limits activity, students construct the limit described in three problems and the formal definition of a limit.   The solutions are not provided.

Students engage in an investigation of the Delta Epsilon Limit with problems that have some limitations. They practice applying the limit and seeing how they are different from common problems. The lesson includes some sample problems...

In this college level calculus learning exercise, students evaluate the given integrals and compute the given limits or show that the limit does not exist.  The three page learning exercise contains ten problems.  Answers are...

Learners engage in a lesson plan about the limits of mathematics. They practice computing the limits in a introduction to a course in calculus. Students are guided through sample problems that are provided in the lesson plan. They...

Learners engage in a lesson plan that is about computing the limits of trigonometric functions. They practice computing the functions of sin, cos, and sin to find the missing values related to triangles. Students also calculate the...

Students investigate the concept of a Limit and how it is used in a variety of problematic situations. They fold paper to help illustrate how to form equilateral triangles and explain how all the angles are the same. The lesson includes...

Twelfth graders define limits and use the delta epsilon definition to solve limits. In this calculus lesson plan, 12th graders investigate the x and y axis using delta epsilon limits. They learn a song to help them remember the definition.

Twelfth graders review limits and continuity. In this calculus instructional activity, 12th graders review the applications and use of limits and continuity for a test. This assignment contains links that are helpful for the review.

In this fossil fuels worksheet, students will determine why fossil fuels are a limited resource and brainstorm possible solutions. This worksheet is a graphic organizer.

During this game, kids become migratory shorebirds and fly among wintering, nesting, and stopover habitats. If they do not arrive at a suitable habitat on time, they do not survive. Catastrophic events are periodically introduced that...

The clear cartoon style slides in this presentation contain details that affect population growth. Natural disasters and other external factors are listed as density independent factors, and density dependent factors, such as competition...

Elementary ecologists pretend to be migratory hummingbirds. They fly between wintering and nesting grounds, trying to reach a habitat haven. In a musical-chair fashion, some birds will miss out, and are removed from the game. To further...

In this chemistry overview worksheet, students calculated the volume of different gases and liquids given in a word problem. Students had to calculate the molecular mass and write the empirical formula and the molecular formula.

Ecology enthusiasts explore ecosystems with this worksheet. They define vocabulary terms and write out answers to questions about distribution and abundance of life. They complete a chart comparing abiotic and biotic factors of Earth's...

Salmonella poisoning impacts over 200,000 people in the United States each year. Scholars learn about the growth of these bacteria using multiple approaches. Then they apply the same growth calculations to endangered species and think...
