Students learn about kinetic and potential energy, including various types of potential energy: chemical, gravitational, elastic and thermal energy. They identify everyday examples of these energy types, as well as the mechanism of corresponding energy transfers. They learn that energy can be neither created nor destroyed and that relationships exist between a moving object's mass and velocity. Further, the concept that energy can be neither created nor destroyed is reinforced, as students see the pervasiveness of energy transfer among its many different forms. A PowerPoint(TM) presentation and post-quiz are provided.

Students are introduced to the definition of energy and the concepts of kinetic energy, potential energy, and energy transfer. This lesson is a broad overview of concepts that are taught in more detail in subsequent lessons and activities in this curricular unit. A PowerPoint(TM) presentation and pre/post quizzes are provided.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Overconsumption of food is one factor linked to obesity. In certain individuals, the pleasure experienced from food rewards may override signals indicating “I’m full.” One possible influencer in this process is the gut microbiome. The composition of the gut microbiota is known to be unbalanced in obesity. But how it contributes to further dysregulating eating behaviors via the food reward system is poorly understood. To assess the role of the gut microbiota in food intake regulation, researchers transferred gut-microbe-containing fecal material from obese donor mice into lean recipient mice. Experiments revealed that recipient mice developed excessive motivation for a food reward and that the gut microbes from obese donor mice altered the brain reward system of recipient mice. Motivation for food rewards was associated with changes in gut microbe-produced metabolites. with the metabolite 33HPP being identified as a modulator of neurotransmitter signalling..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

Through a teacher demonstration using water, heat and food coloring, students see how convection moves the energy of the Sun from its core outwards. Students learn about the three different modes of heat transfer (convection, conduction, radiation) and how they are related to the Sun and life on our planet.

This course is the first of a two term sequence in modeling, analysis and control of dynamic systems. The various topics covered are as follows: mechanical translation, uniaxial rotation, electrical circuits and their coupling via levers, gears and electro-mechanical devices, analytical and computational solution of linear differential equations, state-determined systems, Laplace transforms, transfer functions, frequency response, Bode plots, vibrations, modal analysis, open- and closed-loop control, instability, time-domain controller design, and introduction to frequency-domain control design techniques. Case studies of engineering applications are also covered.

This lesson guides students through an investigation of the expansion and contraction of metal due to changes in temperature.

Astronaut Randy Bresnik talks about the challenges of working in the raging heat and freezing cold. Also check out an experiment you can do in your classroom.

Astronaut Randy Bresnik explains the main ways astronauts communicate with people on Earth. Also learn about how satellites work in a hands-on classroom activity.

This lesson will investigate the difference between longitudinal waves and transverse waves, and how they are able to transmit energy from one location to another.

My passion is to help students seamlessly transfer from their original dream school (in one of the City Colleges of Chicago) to their four-year dream schools and to obtain funding. For that purpose, I have composed a book entitled Transfer Like a Rockstar! Tips on Transferring from Community College to Your New Four-year Dream School. I hope that you enjoy it!

In this lab students will be able to provide and follow directions in groups of two. They will also learn how to interpret subway line network map and discuss when to get off at certain stations.
