Essential Science for Teachers: Life Science: Session 2. Classifying Living Things
How can we make sense of the living world? During this session, a systematic approach to biological classification is introduced as a starting point for understanding the nature of the remarkable diversity of life on Earth.,This segment asks four questions about an organism that will be useful for classification: 1. Does it have more than one cell? 2. Do the cells contain a nucleus? 3. Is there a cell wall? 4. How does it obtain food?
Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,The interviewer uses the phenomena of Mt. Everest's formation to elicit the student's thinking about how the mountain formed. He asks the student to represent her ideas in a drawing. The student reveals that she has an idea of the 2 land masses slowly "drifting" and coming together but struggles with the idea of what it is drifting on. She seems to confuse weathering away of land masses by ocean currents as a me
Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,The interviewer probes the student's ideas about how organisms like lichens and bacteria can break down rock. The video shows the student has some naive ideas about decomposers but does have a basic idea that there are organisms that break down rock.
Internet Scout Project
The Natural Resources Conservation Service provides an array of materials to assist people with their understanding of soils. Through an online presentation, users can learn ten key points about soil characteristics and their importance. Teachers and students can find many fun activities including soil erosion and particle size demonstrations and soil songs. The website provides a great introduction to soil formation and classification. Those contemplating a career in soil science can discover t
What is Inquiry?
Good science education requires both learning scientific concepts and developing scientific thinking skills. Inquiry is an approach to learning that involves a process of exploring the natural or material world, and that leads to asking questions, making discoveries, and testing those discoveries in the search for new understanding. Inquiry, as it relates to science education, should mirror as closely as possible the enterprise of doing real science.
Selenium: A Window on Wetlands Activity
Wetlands are natural recycling plants, but they are often endangered by the waste people put there. Understanding the complex processes that enable a marsh to clean water, recycle nutrients, and immobilize toxic elements will help us protect these diminishing resources. Bring the scientific research done at the the Advanced Light Source into your classroom using this complete teaching module.
Respiratory System 2 from the course General Human Anatomy
General Human Anatomy - Fall 2006. The functional anatomy of the human body as revealed by gross and microscopic examination.
This course introduces students to the basic concepts, logic, and issues involved in statistical reasoning. Major topics include exploratory data analysis, an introduction to research methods, probability, and statistical inference. The objectives of this course are to give students confidence in manipulating and drawing conclusions from data and provide them with a critical framework for evaluating study designs and results. An important feature of the course is the use of an intelligent tutori
This introductory course in "Modern Biology" covers topics found in the fields of cellular biology, molecular biology, biochemistry, and genetics. It does not cover organismal biology or taxonomy. This course is a requirement for biology majors at Carnegie Mellon University. The course is carefully planned to provide the background biology students will need for advanced biology classes. Non-biology majors will also find this course useful as it explains many of the concepts and techniques curre
Introduction to Stoichiometry
Our on-line Chemistry course covers stoichiometry and demonstrates our scenario based approach to teaching chemistry. Traditional courses tend to follow a bottom-up approach to learning chemistry. This traditional approach teaches abstract concepts and tools before discussing their practical application, which results in students learning bits of unconnected knowledge that are rarely usable let alone memorable. In our approach, scenarios are used both to motivate the material and provide a frame
Molecular Stepping Stones
A molecular approach to biology must develop in students an understanding of molecules, their interactions and the consequences of these interactions. Biological phenomenon now more than ever rely on chemical and physical principles for molecular explanations of the phenomenon. We have selected 10 physical-chemical principles that underlie many biological processes: we call them "Molecular Stepping Stones." Below are links to entry level model-based activities for the Stepping Stones.
The Better Angels of Our Nature
Violence has been in decline for millennia. We once lived in a world in which human sacrifice, sadistic torture, brutal slavery, political murder, and blood sports were commonplace. Using more than a hundred graphs and maps, Steven Pinker shows that the conventional wisdom that we are living in a violent era is an illusion. Drawing from psychology, history, brain science, war studies, game theory, complexity theory, and popular culture, Pinker explores where violence comes from, why it has been
Students are introduced to the idea of electrical energy. They learn about the relationships between charge, voltage, current and resistance. They discover that electrical energy is the form of energy that powers most of their household appliances and toys. In the associated activities, students learn how a circuit works and test materials to see if they conduct electricity. Building upon a general understanding of electrical energy, they design their own potato power experiment. In two literacy
This learning object seeks to engage the learner through attractive use of visualisation. As the subject is 'repetition' this is illustrated by using repeated actions to move an object across a screen. Redundancy is built in to help weaker students, but this may be bypassed. 'Scaffolding' is used near the end of the object to enable the learner to engage in building the programming construct in a safe supportive environment. This takes the form of building the code by selecting from code fragmen
French Intermediate RLO 22 - describing accommodation
This RLO contains a reading comprehension exercise that involves finding equivalent expressions for describing accommodation.
Lecture 18 - 11/30/2010
European Questions – Turkish angles: Europe's citizens
Editor's note: Unfortunately the last few minutes of the lecture are missing from the podcast. This series of events explores how our understanding of Europe's identity can be enhanced and developed in a new way by taking in a distinctively Turkish perspective. Richard Bellamy is professor of political science and director of the School of Public Policy at UCL. Thomas Diez is professor of political science and international relations at the University of Tübingen. Maurice Fraser is a senior fel
One of three divisions within the Office of Space Science at NASA, the Sun-Earth Connection has the primary goal of understanding the Sun, Heliosphere, and planetary environments as a single connected system. The Web site offers visitors information on space science missions including the Living with a Star and Solar Terrestrial Probes mission. Meeting notes and official reports can be viewed online, including the Sun Earth Connection 2002 Strategic Plan. Other items of interest include informat
11. The Dog Ice Cream (That’s Amore!)
This time’s news is all about our beloved four-legged friends: dogs. – VIP Member Ashley from London, England emailed us a wonderful article about how she loves to spoil her puppy with a tasty little treat… an ice cream exclusively made for dogs! – So, just listen to this great story all while learning some [...]
Under the Spell of ... Spiders!
Spiders are endlessly fascinating and a great school subject because they offer plenty of teachable topics that span the curriculum. We've tried to provide some of those topics here in these lessons, as for all their amazing physical features and unusual habits, spiders, with just a few notable exceptions, pose little threat to humans and are creatures deserving of understanding and respect. It's our hope that, as you work through the activities, your students will gain a new appreciation for sp
