Motion Through a Fluid: Drag Force and Terminal Speed
Professor Steven Pollock explains motion through a fluid with drag force and terminal speed in this video from Thinkwell's online Physics series. Professor Pollock analyzes several examples and works out the formulas using a white board. Other key concepts: friction, density, area, velocity, and acceleration. Run time 11:58.
5.3.2 Productivity difference The preceding discussion has only considered what would happen if all women undertake less investment in human capital than men. If men and women invest to the same extent, human capital theory suggests that no wage differences would be observed. What happens, however, if there are differences in skill levels both between genders and within gender groups? To consider this we will also make the additional assumption that firms do not know when recruiting workers who are the most productive. Ho

Compare and Order Numbers to 1,000
This Notepad Tutor episode, that is part of the Pilot Math 4 series, explains how to compare and order numbers up to 1,000 using base 10 blocks. Instructor uses an interactive white board to demonstrate the concepts. Instructor highlights place value. Excellent teaching and clear examples. (4:28)
Lunch with a Laureate: Eric Chivian
In 1978, in his last years of residency in psychiatry at Mass General Hospital, Eric Chivian decided to do something bold. Encouraged by Australian physician, Helen Caldicott, who spoke of the medical dangers of the nuclear fuel cycle and of nuclear power, in particular, he decided to restart an old medical organization—Physi
The Precious Envelope
Without the earth's atmosphere, life would not be possible. Many different gases make up the atmosphere in varying concentrations. Human actions are threatening the delicate balance of these gases. The earth's atmosphere is examined through theories of chemical evolution; ozone depletion and the greenhouse effect are explained.
What's Wrong with History?
Understand how students are missing key concepts in history. (01:25)
This module covers the history of attitudes, beliefs, and theories about the etiology of schizophrenia. While the illness was long thought to be environmentally caused, this module emphasizes the scientific evidence in support of its organic origins. Dr. Arnold Scheibel of UCLA Medical Center describes cellular pathology in the hippocampus and speculates on the possible
Sarah—Grade 5 Sarah, a fifth-grade teacher, wants to ensure that her students understand core science concepts.

Workshop 3: Conceptual Thinking
In this workshop, the focus is on concept maps as tools for helping students learn. Joseph Novak, Professor of Biological Science, explains how students learn by assimilating new concepts into their already existing frameworks and takes a teacher step-by-step through the design and process of concept mapping. You will see concept maps being used in a variety of ways in m
Connecting With the Arts: What Are Connecting Concepts?
This program presents strategies for planning lessons that integrate the arts with other subjects. Participants will see how teachers organize instruction around themes and concepts.
Workshop 6: Algebra and Calculus: The Challenge
With Professor James Kaput. Professor Kaput of the University of Massachusetts, Dartmouth, studies children’s understanding of algebra and calculus. Historically, these topics have presented students with significant problems, and we tend to see it as a given that children will struggle with them. Kaput finds many ways of embedding algebra and calculus concep
Learn what acceleration is and how it effects the velocity of objects in this short, computer animated video. Key concepts covered are: acceleration, velocity, constant velocity, constand acceleration, distand per second, and constand acceleration rate. Video ends with a 10 question, fill in the blank quiz.
Atoms and Molecules
This program deals with teaching the very first steps of chemistry. It introduces the basic building blocks — the atoms — which, through their properties, periodicity and binding, form molecules. The program offers different ways to represent these basic concepts by creating useful models in the minds of new chemistry students. It follows the development of these con
Energetics and Dynamics
This program emphasizes the importance of learning about energetics and dynamics in order to improve students’ understanding of basic principles of chemistry. The complexity of teaching concepts such as the collisions theory, reaction kinetics, and electronic energy levels is introduced using a variety of teaching strategies. These concepts are related to everyday phenomena thro
This program deals with basic concepts that are required for the understanding of chemical design. The idea is brought about by experiences from everyday life, such as the stoichiometry of baking, the ingredients of soft drinks, the components of drugs, and the chromatography of markers. The tools of the chemical designer — the chemist — are found in the laboratory,
Dorcas Gonzalez-Lantz, 6th Grade
Students learn about matter and molecules as they investigate the relationships between energy and changes of state by observing water change from ice to steam. Students share, discuss, and analyze their theories. They must be able to defend their answers and answer classmates' questions, thus demonstrating conceptual understanding.
Workshop 1: What is Energy?
Interviews about energy with children, scientists, and people on the street reveal the wide range of concepts that teachers encounter. In this session, you will look at the differences between the everyday language of energy and the scientific concept, see highlights of its history, and learn its importance in our understanding of the world.
Donald Duck In Mathmagic Land (Part 3 of 3) Intelligence and Culture Really Writing Main Idea and Details Chant
The issue of cultural bias in testing is explored in this module, presenting Judy Kearins’s work with Australian children. White and aboriginal children are shown to perform differently on visual/spatial tasks, and use different methods to arrive at solutions to the problems presented. Theories of cultural influence on cognitive processing and the shaping of the brain
This video show a classroom of primary school students reciting a chant reminding them to use a main idea and strong details when they are "really writing". While short and simple, the chant would work to reinforce the concepts of main idea and supporting details with young students.
