From Soap Bubbles To Cell Membranes, Peter Beltramo
From Soap Bubbles To Cell Membranes, Peter Beltramo
Science and Engineering Saturday Seminars
Have you ever blown a soap bubble and wondered - what causes the bubble to be so stable and produces those colorful reflections of light? The answer lies in a class of molecules known as surfactants, and they have remarkable similarities with the molecules that comprise the cell membrane of all living organisms. In this workshop, we will use the analogy of a soap bubble to describe cellular membrane properties such as chemistry, structure, membrane transport, and ion channel formation. The goals of this workshop are to 1) link initially intractable concepts in biology like intracellular transport to the intuitive …

The Core Of Social Network Modeling: Industrial Engineering., Shannon C. Roberts, Chaitra Gopalappa, Nazanin Nazanin
Science and Engineering Saturday Seminars
Networks are abound in our everyday lives, from disaster response networks to cellular networks to social networks. In this workshop, we will introduce the different types of networks and how Industrial Engineering is used to model these networks. Next, we will describe current social network modeling research done at UMass. Finally, we will delve into hands-on activities that include social network analysis, such as the clustering of people into groups, and modeling of the spread of ideas in a social network, such as how tweets spread on Twitter.

Brain Science = Biology + Engineering, Jennifer Welborn, Guangyu Xu, Morton Sternheim, Chris Emery
Science and Engineering Saturday Seminars
This interdisciplinary (physical and life sciences) seminar exposes participants to cutting edge research at UMASS, Amherst, on cell imaging using a chip which gathers a variety of data on the activities of single cells. Part of the seminar will be a presentation of current research in this area, followed by hands-on activities and a visit to the lab where this research is conducted. Application of this new technology to brain research will be discussed as well as the NGSS standards alignment and classroom applications at various levels and disciplines.

STEM Digital
Digital cameras and computers are widely available for students and teachers. However, they are mainly used for documentation: creating PPT presentations, handouts, posters, etc. STEM DIGITAL shows how digital image analysis can be applied to environmental (and other) research in STEM courses. Application to studies of air quality, water quality, arsenic contamination, climate change, diffusion, etc.

Why are Polar Regions more affected by global warming than other parts of the globe? One reason (there are others) is that as sea ice melts and more open water appears, more energy is absorbed, and warming accelerates. This is a form of positive feedback and it makes the polar climate change faster than the climate in temperate areas. Increasing vegetation on land also has a similar positive feedback effect. This effect is a change in the albedo – the fraction of the incident sunlight that is reflected back to space.

Do Crayfish Change Color If Their Environment Changes? A Guided Inquiry Lab for 7th grade Life Science
Background: There is anecdotal evidence from bass fisherman that crayfish are able to change color depending on their surroundings. A (cursory) literature review of this phenomenon showed that no formal research has been done in this area. Students had an additional informal lesson about research funding (or lack thereof) because of this finding.
Students designed and conducted a controlled experiment to see the effect of changing environment color on crayfish color.
ADI was used to quantify a color change.
Human Variation In Skin Color And Race As A Social Construct, Jennifer Welborn
Human Variation In Skin Color And Race As A Social Construct, Jennifer Welborn
STEM Digital
This lesson is part of evolution unit which follows heredity and genetics
The lesson is interdisciplinary in nature in that I discuss the concept of race as a social construct and the idea that there are “black, white, red, yellow” skinned people is something that people developed. It is not based on biology. Race groupings are human-made groups.
Students first learn about mixing light and how to determine black and white from an ADI analysis. They learn that red and green = yellow, etc.
They then photograph each other’s forearms and analyze the images using ADI.
We then discuss skin …
