Classifying Animals by Appearance Versus DNA Sequence
Conditions of Use:
Remix and Share
Rating

The topic of this video module is how to classify animals based on how closely related they are. The main learning objective is that students will learn how to make phylogenetic trees based on both physical characteristics and on DNA sequence. Students will also learn why the objective and quantitative nature of DNA sequencing is preferable when it come to classifying animals based on how closely related they are. Knowledge prerequisites to this lesson include that students have some understanding of what DNA is and that they have a familiarity with the base-pairing rules and with writing a DNA sequence.

Daisy World Model
Conditions of Use:
Remix and Share
Rating

The Daisy World model is intended to illustrate a mechanism through which biota might optimize their environment by means of negative feedback. The model offers a very simplified approach to a feedback system and can provide an introductory lesson in how models work. The aim of the model is to implement and test a mathematical model describing possible influence of biota on an abiotic (climatic) system using GAWK and GNUPLOT. The model tests the hypothesis that biota can influence the planetary environment. This site contains the online model of Daisy World for use in introductory courses as well as an assignment based on the model.

Discovering Medicines, Using Robots and Computers
Conditions of Use:
Remix and Share
Rating

Scientists who are working to discover new medicines often use robots to prepare samples of cells, allowing them to test chemicals to identify those that might be used to treat diseases. Students will meet a scientist who works to identify new medicines. She created free software that ''looks'' at images of cells and determines which images show cells that have responded to the potential medicines. Students will learn about how this technology is currently enabling research to identify new antibiotics to treat tuberculosis. Students will complete hands-on activities that demonstrate how new medicines can be discovered using robots and computer software, starring the student as ''the computer.'' In the process, the students learn about experimental design, including positive and negative controls.

Flu Math Games
Conditions of Use:

This video lesson shows students that math can play a role in understanding how an infectious disease spreads and how it can be controlled. During this lesson, students will see and use both deterministic and probabilistic models and will learn by doing through role-playing exercises. The primary exercises between video segments of this lesson are class-intensive simulation games in which members of the class 'infect' each other under alternative math modeling assumptions about disease progression. Also there is an occasional class discussion and local discussion with nearby classmates.

Methods for Protein Purification
Conditions of Use:
Remix and Share
Rating

This Protein Purification video lesson is intended to give students some insight into the process and tools that scientists and engineers use to explore proteins. It is designed to extend the knowledge of students who are already somewhat sophisticated and who have a good understanding of basic biology. The question that motivates this lesson is, ''what makes two cell types different?'' and this question is posed in several ways. Such scientific reasoning raises the experimental question: how could you study just a subset of specialized proteins that distinguish one cell type from another? Two techniques useful in this regard are considered in the lesson.

Understanding Science: How science really works
Rating

The mission of Understanding Science is to provide a fun, accessible, and free resource that accurately communicates what science is and how it really works. The process of science is exciting, but standard explanations often miss its dynamic nature. Science affects us all everyday, but people often feel cut off from science. Science is an intensely human endeavor, but many portrayals gloss over the passion, curiosity, and even rivalries and pitfalls that characterize all human ventures. Understanding Science gives users an inside look at the general principles, methods, and motivations that underlie all of science. This project has at its heart a re-engagement with science that begins with teacher preparation and ends with broader public understanding. Its immediate goals are to (1) improve teacher understanding of the nature of the scientific enterprise, (2) provide resources and strategies that encourage and enable K-16 teachers to reinforce the nature of science throughout their science teaching, and (3) provide a clear and informative reference for students and the general public that accurately portrays the scientific endeavor. The Understanding Science site was produced by the UC Museum of Paleontology of the University of California at Berkeley, in collaboration with a diverse group of scientists and teachers, and was funded by the National Science Foundation1. Understanding Science was informed and initially inspired by our work on the Understanding Evolution project, which highlighted the fact that many misconceptions regarding evolution spring from misunderstandings of the nature of science. Furthermore, research indicates that students and teachers at all grade levels have inadequate understandings of the nature and process of science, which may be traced to classrooms in which science is taught as a simple, linear, and non-generative process. This false and impoverished depiction disengages students, discourages public support, and may help explain current indications that the U.S. is losing its global edge in science. Even beyond the health of the U.S. economy, the public has a genuine need to critically assess conflicting representations of scientific evidence in the media. To do this, they need to understand the strengths, limitations, and basic methods of the enterprise that has produced those claims. Understanding Science takes an important step towards meeting these needs.
