How many calories are in your favorite foods? How much exercise would you have to do to burn off these calories? What is the relationship between calories and weight? Explore these issues by choosing diet and exercise and keeping an eye on your weight.

Students will explore and create a healthy ecosystem, once established they will then introduce additional variables which may harm the ecosystem and determine which hazards should be avoided.

This activity begins as a classroom investigation, but may extend to a field investigation where students will determine the effects of air temperature on seed germination. This is accomplished by developing investigative questions, recording, and analyzing data.

This video shows 15 years of data obtained via Polar-orbiting satellites that are able to detect subtle differences in ocean color, allowing scientists to see where there are higher concentrations of phytoplankton - a proxy for the concentration of chlorophyll in the ocean.

In this media-rich lesson, students learn how global warming is changing the Alaskan environment and examine the consequences of climate change on the region's human and wildlife inhabitants.

In this animation produced by WGBH and Digizyme, Inc., see how molecules of DNA are separated using gel electrophoresis, and how this process enables scientists to compare the molecular variations of two or more DNA samples.

In this electrochemistry activity, learners will explore two examples of electroplating. In Part 1, zinc from a galvanized nail (an iron nail which has been coated with zinc by dipping it in molten zinc) will be plated onto a copper penny. In Part 2, copper from a penny will be plated onto a nickel.

A learning activity for the "All About Earth: Our World on Stage" book in the Elementary GLOBE series. In pairs, students will create experimental conditions in terrariums in order to study what plants need to live. Variables to study include the presence or absence of soil, water, and sunlight. Students will record the growth of radish plants as well as observations of "the water cycle" in their terrariums. At the conclusion of their experiments, students will share their results with the class and discuss how water, Earth materials, and air are all necessary to support living things. The purpose of the activity is to acquaint students with the hydrosphere, geosphere, atmosphere, and biosphere more closely, to have students use microcosms to study natural phenomena, and to introduce students to the concept of a "fair test" in a scientific investigation. After completing this activity, students will know about the importance of the hydrosphere, geosphere, and atmosphere in supporting the biosphere. They will learn how to set up "fair test", record detailed observations, use drawings as scientific records, make sense of experimental results, and share them publicly.

Scientists discuss whether or not endocrine disrupting chemicals, which may cause birth defects and other health concerns, should be controlled in the absence of conclusive proof, in this video segment adapted from FRONTLINE: Fooling with Nature.

This feature, adapted from Interactive NOVA: "Earth," follows the path of energy as it is transferred via the food chain from one type of organism to another.

This video segment, adapted from NOVA, describes the energy flow in a coral reef, including its food web.

Spreadsheets across the Curriculum module. Students build spreadsheets that allow them to calculate the different values needed to examine energy flow through agroecosystems.

This classroom activity introduces students to energy flow through organisms, producers & photosynthesis, and consumers & respiration.

This issue of the free online magazine, Beyond Penguins and Polar Bears, explores the Sun's role in warming Earth, the albedo (reflectivity) of Earth's diverse surfaces, and how the decline of Arctic sea ice is affecting Earth's energy balance. Science lessons introduce the concepts of solar energy, reflection, and absorption to elementary students. The issue also includes an overview of the natural resources and energy sources found in the polar regions as well as lessons that allow students to develop the concepts of natural resources, energy sources, and energy efficiency.

This article highlights children's literature about light, heat, and energy sources for use in the elementary classroom.

Students are introduced to genetic techniques such as DNA electrophoresis and imaging technologies used for molecular and DNA structure visualization. In the field of molecular biology and genetics, biomedical engineering plays an increasing role in the development of new medical treatments and discoveries. Engineering applications of nanotechnology such as lab-on-a-chip and deoxyribonucleic acid (DNA) microarrays are used to study the human genome and decode the complex interactions involved in genetic processes.

Under the "The Science Behind Harry Potter" theme, a succession of diverse complex scientific topics are presented to students through direct immersive interaction. Student interest is piqued by the incorporation of popular culture into the classroom via a series of interactive, hands-on Harry Potter/movie-themed lessons and activities. They learn about the basics of acid/base chemistry (invisible ink), genetics and trait prediction (parseltongue trait in families), and force and projectile motion (motion of the thrown remembrall). In each lesson and activity, students are also made aware of the engineering connections to these fields of scientific study.

Lesson 1 introduces students to the blow fly's life cycle and the accumulated degree hour (ADH) used by forensic entomologists for estimating the time of death. Lesson 2 introduces Dr. Krinsky's entomological work in solving a murder case in 1986. Students access several primary-source documents related to Dr. Krinsky's entomological work. Both lessons help students expand their understanding of a forensic entomologist's work and appreciate how scientists account for environmental/variable factors in forming a conclusion in a scientific study.
