This trick from Exploratorium physicist Paul Doherty lets you add together the bounces of two balls and send one ball flying. When we tried this trick on the Exploratorium's exhibit floor, we gathered a crowd of visitors who wanted to know what we were doing. We explained that we were engaged in serious scientific experimentation related to energy transfer. Some of them may have believed us. If you'd like to go into the physical calculations of this phenomenam, see the related resource "Bouncing Balls" - it's the same activity but with the math explained.

Exploring Energy: Kinetic and Potential
Read the Fine Print
Educational Use
Rating
0.0 stars

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.

Gut microbes and their metabolites mediate food reward motivation in obesity

0.0 stars

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.

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!
