Groups explore illumination with NASA's Lighting Environment Test Facility (LETF) as a context. Using the TI-Nspire app, groups determine the lux equation that models their simulation. They then use the lux equation to...

Environmental science enthusiasts show what they know at the end of the year by taking this full-fledged final exam. They answer multiple-choice, graph interpretation, and essay-analysis questions, 73 of them in all. Topics range from...

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...

When judging diversity of an ecosystem, both species evenness and species richness must contribute. After a discussion of diversity and a guided example using the Shannon-Weaver function, scholars use the same function on two other...

First graders look for geometrical shapes in nature to help them appreciate the diversity of the natural environment.

You never know what you will find next in the deep sea ecosystem. So far, scientists have found items that work as anti-tumor agents, anti-inflammatory agents, agents that stop uncontrolled cell division, and much more. The lesson plan...

Seventh graders study how the heart functions and its parts.  In this circulatory system lesson students learn how to take their pulse, blood pressure and respiration. 

Tenth graders study disease and how it changes normal body functions.  In this research lesson students research a disease and use a word processing software to construct a presentation. 

Fifth graders identify and describe the functions of the major body systems. They discover how to maintain a healthy lifestyle with proper nutrition and exercise. They answer comprehension questions to end the activity.

In this living environment worksheet, high schoolers answer 30 multiple-choice questions and 42 short-answer questions in preparation for the Regents exam.

Students examine the kidney donation process and make ethical decisions as various stakeholders in specific case studies. They decide which candidate should receive a kidney donation.

Students investigate the real world applications of nutrition. They study the problem of starvation and how it affects different populations. Students work in small groups in order to devise and intervention plan. They also search out...

Eighth graders demonstrate the mathematical components of a scientific problem as well as illustrate how real world problems can be solved using math. They demonstrate math skills such as rate calculation, graphing, and linear equations.

Students examine how the brain develops. In this neurology instructional activity students read an article citing evidence that the different areas of the brain mature at different rates. They discuss emotional versus logical aspects of...

Students explore and explain how mutations in the DNA sequence of a gene may be silent or result in phenotypic change in an organism and in its offspring. They analyze how evolution and biodiversity are the result of genetic changes that...

Third graders model the tag and recapture of bears and use proportions to estimate the population of the bears in their forest. This is a statistical sampling method used by scientists and naturalists to determine population numbers.

Students participate in a class discussion on site of an older style bridge to help connect the significance of each organism in an ecosystem by using an analogy of bolts slowly being removed from a working bridge.

Seventh graders identify the common bones in the human body. In this biology lesson, 7th graders research two bones assigned to them. They explain why bones are important to us.

In this three-part activity, students apply linear, exponential, and rational functions to explore past and projected U.S. population growth, carbon footprint trend, ecological overshoot, and effectiveness of hypothetical carbon dioxide...
