Plants, Pipettes And Pcr, Elizabeth Vierling
Science and Engineering Saturday Seminars
Plants are amazing organisms that provide us with food, building materials, the pleasure of gardens, as well as providing the foundation of critical world ecosystems. Although they may look like they are just stuck in one place and doing not more than growing, they have many, many complex ways in which they respond to the environment. The goal of this STEM Ed session will be to discuss ways that plants can respond to the environment with hands on exercises and exploration of possible classroom activities. Participants will engage in state-of-the art methods of testing plant DNA composition using the polymerase …

The need to transition to new and cleaner forms of energy has never been more imperative in the face of climate change. At the same time, the twin pressures from increasing global demand for energy and the scarcity of critical materials needed for new energy technologies impose additional challenges in making the transition to clean energy sources. In this workshop, we will explore how theory, modeling, and experiment are rising to the challenge of designing inexpensive, earth-abundant materials to enable the next generation of clean energy technologies. The goals of this workshop are: 1) to integrate concepts from chemistry, physics …

Liquid crystals are a family of materials that can flow like a liquid, while having orientation order, like a crystal. Traditional liquid crystals are formed by small rod- or disk-shaped organic molecules that spontaneously align with each other. The orientation direction of the liquid crystals molecules, or the director, is sensitive to external fields. For example, a few volt of electric field can cause the director rotate 90 degrees and completely change the optical property of the sample. The susceptibility to external fields made liquid crystals an ideal material for optical switching applications, the best example of which is the …

Many natural surfaces, such as lotus leaves and a water strider’s leg, have shown striking water repellency so that they remain clean and dry even in “dirty” habitats. Such water repellency is called superhydrophobicity, which has stimulated lots of science and engineering imagination for self-cleaning windows, never dirty clothes, drag-reduction swimming suits, etc. In this workshop, we will use superhydrophobicity as a model to guide an integrative teaching and learning experience through hands-on experiments, critical thinking, basic science, as well as a lecture on state-of-the-art research discoveries. The objectives of this workshop are to (1) stimulate student curiosity and imagination …

Birds In An Ecological Web, Jeff Podos
Birds In An Ecological Web, Jeff Podos
Science and Engineering Saturday Seminars
One great way to learn about nature and biology is to study birds. There are many species of birds, both resident and migratory, and they all have their own habits, colors, songs, and ways of life. The popularity of birdwatching has skyrocketed in the US, especially during the pandemic. This seminar will describe one way to look at birds, and to learn about their ecology, evolution, and diversity. We start by focusing on birds’ feeding habits and food preferences. Many birds have to eat and forage constantly, in order to stay alive and to feed their offspring. From this starting …
