Explore the forces at work in a tug of war or pushing a refrigerator, crate, or person. Create an applied force and see how it makes objects move. Change friction and see how it affects the motion of objects.

Learn how to make a water filter using materials from around your home or classroom.

Chemistry 130 is a fundamental introductory course presenting chemistry for nursing/allied health, general education and non-chemistry major students.

This activity is a guided practice and scaffolding activity in which the students learn how to configure electrons of elements and determine the number of valence electrons.

This introductory video addresses key points as well as pros and cons of oil as an energy source for transportation.

Short Description:
An open textbook created to improve both teaching and learning vital concepts and techniques in multivariable calculus, one of the fundamental courses across the undergraduate curriculum in science and engineering. The goals of this resource are to help learners develop their geometric intuition about abstract and complex mathematical concepts (e.g., partial derivatives, multiple integrals, vector fields), and train them to make connections between concepts visually (e.g., connecting “vectors” in mathematics with “magnitude” and “direction” in physics) in order to more fully understand engineering, physics and mathematical problems (e.g., differential equations) in their subsequent STEM coursework.

Investigate how torque causes an object to rotate. Discover the relationships between angular acceleration, moment of inertia, angular momentum and torque.

This resource introduces the concept of wind chill, the formula used to measure it and relates it to the causes of hypothermia. A simple experiment using a pie pan, sand, fan and a thermometer demonstrates this concept. The resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

Users can choose a time in geologic history, select the link, and see what the Earth looked liked in the far distant past. Each map features a brief written description of the events occurring at that time, and a link to additional information on the geologic era or period being shown. There are also maps that show what the Earth might look like in the future, 50, 100, and 150 million years from now.

Geographic information systems (GIS), once used predominantly by experts in cartography and computer programming, have become pervasive in everyday business and consumer use. This unit explores GIS in general as a technology about which much more can be learned, and it also explores applications of that technology. Students experience GIS technology through the use of Google Earth on the environmental topic of plastics in the ocean in an area known as the Great Pacific Garbage Patch. The use of this topic in GIS makes the unit multidisciplinary, incorporating the physics of ocean currents, the chemistry associated with pollutant degradation and chemical sorption to organic-rich plastics, and ecological impact to aquatic biota.

This is an activity about solar energy. Learners will first use computers to research and learn how solar panels convert sunlight into electricity. Next, they will calculate the surface area of solar panels board a satellite and their total power generated in various positions of the satellite, given the dimension of the panels. After, learners will organize and write a report summarizing the information about the MMS mission satellites. This activity requires student access to internet accessible computers. This is lesson four as part of the MMS Mission Educator's Instructional Guide.

This online calculator converts from one energy unit to another - from gallons to British thermal units (Btu), kilowatt/hours to megajoules, short tons to metric tons.

This activity allows students to demonstrate their understanding of the Law of Conservation of Energy in the framework of student-designed investigations.

6.977 focuses on the physics of the interaction of photons with semiconductor materials. The band theory of solids is used to calculate the absorption and gain of semiconductor media. The rate equation formalism is used to develop the concepts of laser threshold, population inversion and modulation response. Matrix methods and coupled mode theory are applied to resonator structures such as distributed feedback lasers, tunable lasers and microring devices. The course is also intended to introduce students to noise models for semiconductor devices and to applications of optoelectronic devices to fiber optic communications. This course is worth 12 Engineering Design points.

This activity introduces measurement and scale using hands-on activities. In this activity, students use the concept of similar triangles to determine the height of a tree. This activity is one of several available on an educational poster related to NASA's Space Interferometry Mission.

In this interactive activity adapted from the University of Utah's ASPIRE Lab, investigate frequency in terms of trampoline jumps, pendulum swings, and electromagnetic waves.

In this high school physical sciences unit, students investigate why some substances absorb heat when they react, while others release it. Students first solve the mystery of where the energy goes in endothermic reactions by examining salt dissolution and using magnets as models for bonds. They then expand their investigations to look into where the energy comes from in exothermic reactions. The model they continue to develop using magnets, helps them account for why breaking bonds absorbs energy from the surroundings and forming bonds releases energy back into the surroundings. The end of the unit naturally motivates a new question to pursue in future units, “Why are some types of particles more attracted to one another than others?"

This course explores statistical modeling and control in manufacturing processes. Topics include the use of experimental design and response surface modeling to understand manufacturing process physics, as well as defect and parametric yield modeling and optimization. Various forms of process control, including statistical process control, run by run and adaptive control, and real-time feedback control, are covered. Application contexts include semiconductor manufacturing, conventional metal and polymer processing, and emerging micro-nano manufacturing processes.

Growth and development through the lifespan including physical, social, cognitive and neurological development. This course covers topics in each of these areas and provides an overview on subjects such as day care, education, disabilities, parenting, types of families, gender identity and roles, career decisions, illnesses and treatments, aging, retirement, generativity, and dying.

This is an introductory jumproping lesson for grades K-2. It includes a breakdown of what jumproping is, an individual practice, as well as a group game. This lesson focuses on the benefits of jumproping and why it is a good exercise.
