Force and Motion SciGuide Average User Rating: Whether planning a trip to mars, determining the structure of atoms and molecules, or using tire marks to recreate an automobile accident, many of the applications of science involve prediction of what objects are going to do and how they will interact....  [view full summary] Whether planning a trip to mars, determining the structure of atoms and molecules, or using tire marks to recreate an automobile accident, many of the applications of science involve prediction of what objects are going to do and how they will interact. Fortunately, we know a great deal about such motions and interactions, thanks to centuries of scientists studying just these things. This SciGuide addresses four main themes—describing position and motion, Newton’s first law, Newton’s second law, and Newton’s third law. Accurate and reliable descriptions of where something is and what it’s doing are essential for laying a groundwork for the causes of motion and changes in motion. Newton’s laws, used by scientists and laypeople alike, provide the solid framework of those causes. The contents of this SciGuide will provide resources for understanding and applying all these concepts in a way that will tie the formal statements with practical experiences and applications.

It doesn’t matter where you live or where you travel, weather patterns influence your daily life. In this guide, students will engage in exploring and predicting the conditions in the atmosphere that are responsible for weather patterns and climatic conditions, and investigate how extreme weather impacts humans and the environment. While many of the keywords embedded into the “Living in the Weather” themes will be familiar, do your students really understand them? This guide provides teacher-tested, reliable links that allow you and your students to “surf” the internet in a quest to better understand how atmospheric conditions directly relate to weather on Earth. Understanding weather and climate can be a great opportunity for you to engage students in topics and themes that connect Earth and space science, life science, and physical science in a real way. The National Science Education Standards (NSES) focus on the study of weather and climate and their impact on human life. This guide uses the ongoing work and technology of the National Oceanic and Atmospheric Administration (known to the public simply as NOAA). NOAA scientists study our planet Earth in a global way. Working together with scientists worldwide, NOAA scientists study the diversity of living organisms (including humans) and their impact on our environment—not only in our country but in every country and continent around the world.

How ill can you become? Nausea, vomiting, diarrhea, cramps, and fever are just some of the symptoms that a person can have from food poisoning. Not very pleasant is it? Health authorities have a saying: “First you’re afraid that you’re going to die, then you’re afraid you are not going to die.” In 1999 the Centers for Disease Control and Prevention (CDC) estimated that there were over 76 million cases of gastrointestinal disease including 325,000 hospitalizations and over 5,000 deaths that were directly attributable to food poisoning. The main concern in food-service sanitation is the prevention of illness caused by contaminated food. Bacteria, parasitic worms, and chemicals can all cause food-borne illness. Unfortunately, most food-borne illness is not recognized as such and is therefore seldom reported. By now you are probably wondering why someone would prepare or eat poisoned food? Doesn’t poisoned food taste, look, or smell bad? No! If it did, people wouldn’t eat it. Would you eat a piece of pie that smelled bad? Would you cook a piece of green chicken? Of course not! According to experts at the CDC, the leading factors causing food-borne illness are: Improper cooling, such as leaving cooked foods at room temperature. Lapse of a day or more between preparing and serving. Holding hot foods at the wrong temperature. Improper and inadequate refrigeration of foods. Infected persons touching and handling food. Improper reheating of previously cooked foods. Improper cleaning of kitchen equipment such as knives, pots, and cutting boards.

Scientifically speaking, energy is the ability to do work or the ability to move an object. How can energy be changed? What forms of energy are needed to support life? These and other questions are explored in this guide. Students are intrigued by the idea of living and working in space and their curiosity can be used to better understand the different forms of energy on Earth and in the universe. Space science can be used to teach the abstract concepts of energy and matter by learning about the ways NASA astronauts, scientists, and engineers continue to explore these concepts to develop space colonies and exploration vehicles of the future. The concept of energy is intertwined throughout our study of science whether it be life, physical, Earth or space. As NASA and its world partners continue to build the International Space Station, scientists and engineers on Earth will use the new information to improve our lives in many ways. We may learn new ways of changing, or transforming, energy to create new technologies that can help us use energy more efficiently, and to better understand how energy sources impact humans globally. We can use this knowledge to protect our environment through the use of renewable (such as wind, solar, air) and alternative (such as geothermal, nuclear) resources, to produce new and better medicines to treat illness and disease, and to create new and improved technologies for the advancement of Earth and space science. This web guide offers teachers a motivational “hook” to get students engaged in the study of energy by providing teacher-evaluated links to NASA resources. It is through these links that students discover how living in space relates to living on Earth. Lesson plans and web links correlate to the National Science Education Standards (NSES) as well as technology standards and the AAAS benchmarks. NASA has a wealth of educational resources available online; this guide is meant to provide teachers with a streamlined way to incorporate these resources into the classroom.

Our images have been of "little green Martians." Before we can learn and understand the complexity known as Mars, we must first learn about Earth. Using "Earth-The Making of a Planet" by Roy Gallant and Christopher Schuberth, discovering and exploring Earth will assist us in our journey to Mars. Before searching the wide variety of web sites, we will also review the Astrobiology Goals mentioned in the Astrobiology Roadmap. See web site-http://astrobiology.arc.nasa.gov/roadmap/ With our two explorer rovers, Opportunity and Spirit, both traversing the surface of the red planet, together with the research data and pictures that we have previously received from the Viking and Pathfinder missions, we now speculate that life may exist now or has existed in the past on Mars. Scientists believe that life on Mars was/is life in the form of bacterial-type organisms, many of which are invisible to the naked eye. Come, join us in a voyage from Antarctica, at the bottom of the world, to Siberia, at the top of the world; from Baja, California to the Bahamas; and from Earth to the Meridiani Planum on Mars. The Internet will connect you and your students, using content and activities, to the study of life on earth and its relevance to the discovery of past and perhaps present life on Mars.

Humans have not ventured to the moon since the Apollo missions from 1969–1972 and those were brief excursions. 30 years later, new technologies and applications have been developed that will make lunar living a reality. Why not incorporate this new and exciting adventure into your study of life, physical, and Earth science in a motivating way? Pique your students’ natural curiosity by using space science as your “hook.” As NASA designs and develops habitats and life support systems for their lunar missions, they will be focusing on the task of having an “Earth like” environment on the moon that contains food, shelter, water, and air for all living things. Scientists and engineers at NASA’s Johnson Space Center have already begun “to make living on the moon a reality.” Beginning with a lunar landing “mock-up” that has a crew cabin with a small galley, waste collection area, sleep area, storage compartments, and even medical supplies, they are designing “mini” space habitats to support life in space for up to seven days. Living in space requires attention to health and fitness, food production and waste management, sources of power, transportation, and communication, and social adaptations that space ecosystems will depend upon. Teaching about ecosystems, habitats, and health through space science helps students to see the real-life application of their studies, transfer their knowledge to other situations, and wonder about the future. Isn’t this what we all want to accomplish when we design our curriculum around the teaching standards? The web resources in this SciGuide will help students learn core science content in a fun, meaningful context. Using what they know about life on Earth, they will make predictions and inferences about the success of human life in space. Now that’s engaging! This web guide offers a variety of resources for you and your students, all of which have been evaluated and rated by master teachers across the country in an effort to make your task of incorporating technology into the classroom easier. Looking for life science lesson plans about ecosystems, populations, interdependence, microorganisms, and more? You will find them in this guide along with interactive simulations, images, hands-on investigations, and content background. NASA strives to provide teachers with standards-based, inquiry lessons and this SciGuide is an example of their efforts.
