Through videos and cooperative learning, students investigate the respiratory system of birds, describe its function, and then compare this to the respiratory function in human mammals.

The biggest misconception of the process of photosynthesis is presented along with other important aspects of this life-building process. [25:21]

There are many misconceptions about the chemistry concept, "Conservation of Mass". Thus, the aim of this video lesson is to teach students about the chemical concept of Conservation of Mass through several chemistry experiments. [17:10] (English Subtitles)

As magic and ephemeral as they may seem, soap bubbles are a magnificent example of precise mathematics, physics and chemistry at work. Part One of this video lesson will explore the science that explains soap bubbles, as well as the application of this knowledge to other areas, such as architecture and biology. In Part Two of this video lesson, students will learn where the colors of soap bubbles come from and also learn what soap bubbles and telescopes have in common. [Part 1: 41:53; Part 2: 26:14]

The idea of this lesson is to introduce, in a simplified manner, the so-called Braess Paradox by providing simple examples to clarify that the addition of some new roads to a network does not always lead to an improvement in the liquidity of the traffic; in some cases it might even increase the time required to get from one point to another if all drivers are selfish. [27:05] (English Subtitles)

Flying kites is a popular hobby in Malaysia and very much part of the culture. This lesson looks at kite flying science to introduce basic ideas related to the dynamics of kite flying and can be used as an extension of a physics lesson, especially after the students have learned about forces. It will focus on some of the concepts such as weight, thrust, lift and drag. [28:59]

Through videos and learning activities, students use programming language knowledge and logical thinking skills to divide problems into steps to be solved by a computer.

This video lesson will focus on systems that are said to be in equilibrium- that is, systems that are not allowed to move away from their original places or rotate about their axis. Students will learn about static equilibrium by exploring themselves what is meant by translational equilibrium and rotational equilibrium and whether an equilibrium is stable, unstable, or neutral. [38:33]

Students move past the misconception that friction inhibits our ability to do things by watching videos and participating in corresponding activities. Activities which range in difficulty include calculating the coefficient of friction.

The main objective of this video lesson is to bring the students' attention to the importance of basic and natural sciences in our lives. The lesson will introduce a topic (sustainable energy) that is related mainly to chemistry and is not usually covered directly in a high school curriculum. [33:34]

An MIT graduate student guides a classroom through fun activities that will introduce students to graph theory. The goal of these activities: find a route through a town without crossing the same path twice. Video is accompanied by a teacher's guide, a transcript, a class handout, and several links to information on graph theory. [55:25]

This lesson is an introductory topic in thermodynamics, on the conversion of energy. The aim of this video is to support students in visualizing the conversion of energy and its importance in real world applications. [24:07]

How is it that all cells in our body have the same genes, yet cells in different tissues express different genes? A basic notion in biology that most high school students fail to conceptualize is the fact that all cells in the animal or human body contain the same DNA, yet different cells in different tissues express, on the one hand, a set of common genes, and on the other, express another set of genes that vary depending on the type of tissue and the stage of development. [29:12]

After viewing video components, students use manipulatives to work with the famous Towers of Hanoi problem. The goal is for learners to begin to understand recursive logic and thinking, relevant to computer scientists, mathematicians, and engineers.

This lesson introduces students to the "Tragedy of the Commons," an extended metaphor for problems of shared environmental or man-made resources that are overused and eventually depleted. In this metaphor, shared resources are compared to a common grazing pasture, or commons, on which any dairy farmer can graze as many cows as he/she wishes. [31:34]

The objective of this video lesson is to correct the misconception in the students' understanding of centrifugal force. The lesson will work to clarify this misconception by using Newton's three laws of motion, particularly the law of inertia, and will demonstrate that the only force acting during a uniform circular motion is centripetal force (i.e., towards the center) - not including the force of gravity. [27:04] (English Subtitles)

This lesson focuses on the molecular biology technique of DNA fingerprinting: what it is, how it works, and how the data from these experiments are used for paternity testing and forensics. [45:48]

This video is meant to be a fun, hands-on session that gets students to think hard about how machines work. It teaches them the connection between the geometry that they study and the kinematics that engineers use - explaining that kinematics is simply geometry in motion. [52:49]

The major purpose of this lesson is to promote the learning of eye function by associating eye problems and diseases to parts of the eye that are affected.

Through videos and cooperative learning, students to are introduced to algorithmic thinking within a popular field in graph theory, social networking.
