In this video lesson, students will learn about the DNA fingerprinting of plants by studying the following real world problem: A farmer bought olive trees of the variety called "nabali", known for producing high amounts of oil. However, he worried that he may have been sold the wrong variety. [29:55]

In this video lesson, students will learn about linear programming (LP) and will solve an LP problem using the graphical method. Its focus is on the famous "Stigler's diet" problem posed by the 1982 Nobel Laureate in economics, George Stigler. [30:47]

Determining the position of a star or other object in three-dimensional space is an important concept in astronomy. Finding stellar longitude (called right ascension) and latitude (declination) is easy enough, but it is much harder to find the radial distance to those objects. This lesson teaches how the distances to nearby stars are measured using the parallax effect: as the Earth orbits our sun, the positions of the nearest stars seem to wiggle back and forth compared to more distant stars. [26:03]

This learning video explores the mysterious physics behind boomerangs and other rapidly spinning objects. Students will get to make and throw their own boomerangs between video segments! A key idea presented is how torque causes the precession of angular momentum. [30:59]

This video lesson explores Newton's Third Law of Motion through examination of several real world examples of this law in action, including that of a donkey cart - a site common in the streets of Pakistan. Students will understand that forces act on objects even if the objects appear to be static and that certain conditions - gravity in particular - affect how two objects interact. [32:59]

The objective of this lesson is to illustrate how a common everyday experience (such as playing pool) can often provide a learning moment. In the example chosen, we use the game of pool to help explain some key concepts of physics. [24:41]

This video lesson discusses how a few simple physics concepts can help in understanding various factors that influence the performance of racing cars. Students will also learn how these same concepts influence the design and development of a racing car that is safe and able to compete in various racing conditions. [32:51] (English Subtitles)

Earth contains a variety of plants to provide food, medicine and, most importantly, energy sources for humans. In this lesson, students will categorize plants by their components and shapes. Additionally, they will learn the mechanisms behind the making of medicines and bio-fuels. [20:57] (English Subtitles)

In this video lesson, students will achieve the following learning objectives: 1) Become familiar with the fourth state of matter, "plasma"; 2) Understand the concept of plasma: 3) Compare the four states of matter; and 4) Learn some applications of plasma. [28:24]

Interactive video lesson discusses the distribution of electrons in a carbon atom, and then follows with a chemical investigation of plastics.

Through this video lesson, students compare exponential growth to polynomial growth and discover how quickly the number can grow or decay in exponentials.

The main objective of this lesson is to motivate students' thoughts and get them excited about some probability concepts. The aim is to present probability theory in as simple a manner as possible. It is hoped that students will learn that probability theory is a basic tool for handling an uncertain future and making a decision. [34:43]

This lesson focuses on the biggest problem faced by any young programmer, the logic building required while solving a particular problem.[28:25]

This video lesson presents a real world problem, one that a juice seller faces daily, that can be solved by using the Pythagorean theorem. [33:54]

In this video lesson, students will not only learn about Pythagoras and the Pythagorean Theorem, but they will also demonstrate a proof of this theorem, use it to solve problems, and create their own real world problems to challenge the class. [57:05]

Use this video to help teach the Pythagorean Theorem. The video can be downloaded, there is a transcript of the video, and a teacher's guide to aid in using the video. [21:38]

This lesson is about energy and how it manifests itself in every day things and events. In particular, the video focuses on quantification or estimation of energy. The main learning objectives are to: gain familiarity with units of measure such as Joules and calories; to appreciate the relationships among forces, distances, and energy; and to have a familiarity with various forms of energy including mechanical, kinetic, potential, and chemical. [38:09]

The scope of this video lesson consists in studying the sets of Rational and Irrational numbers. The main objectives for the students are: 1) Learning how to distinguish between a rational number and an irrational number; 2) Learning about the existence of 2 infinities: the "countable infinity" for sets of Rational numbers and the "uncountable infinity" for the set of irrational numbers; and 3) Learning to use straightforward and advanced tools from Mathematics to reach goals (1) and (2). [43:13]

An interactive video lesson where students first determine misconceptions about what happens during chemical reactions, and then investigate some various chemical reactions.
