In this video module, students learn how scientists use genetic information from dogs to find out which gene (out of all 20,000 dog genes) is associated with any specific trait or disease of interest. This method involves comparing hundreds of dogs with the trait to hundreds of dogs not displaying the trait, and examining which position on the dog DNA is correlated with the trait. [34:17]

Students meet a scientist who created software that looks at images of cells and determines which images show cells that have responded to 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. [28:24]

This lesson presents a comprehensive overview of diabetes, including the causes of as well as the biological processes leading to this widespread disease. Students will learn about the symptoms of diabetes and will become knowledgeable about healthy behaviors that can lead to the prevention of the disease. [32:18] (English Subtitles)

This video lesson introduces students to the worlds of engineering innovation and entrepreneurship. It seeks to encourage students to see the world with a fresh perspective for innovation through interactive classroom brainstorming activities and real life stories. [33:45]

As part of this introduction to cryptography, students will build three devices and learn how to encrypt and decrypt messages. Video is accompanied by a teacher's guide, transcript, and other handouts, as well as links for learning more about ciphers, cryptography, and code breaking. [21:26]

Former MIT student introduces the classroom to fractal geometry via a video presentation appropriate for students who have had two years of high school algebra. Video lesson content includes the "chaos game" and trajectory calculations and is accompanied by a teacher's guide, transcript, and printable tutorial, quiz, and problems. [32:31]

The aim of this video lesson is to introduce the concept of factorials, and to show students that everyday events in their lives have so much to do with factorials - even if they do not realize it! During this video, students will learn about the large number of ways to arrange people and objects using the mathematical concept of factorials. [2:14] (English Subtitles)

A University of Jordan physics professor leads an activity in which students measure gravity by observing a swinging pendulum and gathering related data. Video presentation is accompanied by a teacher's guide, other printable material, and additional online resources. [23:16]

A video presentation in which two MIT Ph.D. students take a look at how averages can be misunderstood, or the "flaws of averages." Using a few real life examples, the students apply knowledge of these "flaws" when examining functions. Video is accompanied by summary, teacher's guide, transcript, supplementary materials, and several links for further reading. [18:42]

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. [33:55]

This video lesson is an example of "teaching for understanding" in lieu of providing students with formulas for determining the height of a dropped (or projected) object at any time during its fall. The concept presented here of creating a chart to organize and analyze data collected in a simple experiment is broadly useful. [32:25]

Students paticipate in a hands-on lesson discovering how cancer is caused by mutations that accumulate over time.

This video lesson has the goal of introducing students to galaxies as large collections of gravitationally bound stars. It explores the amount of matter needed for a star to remain bound and then brings in the idea of Dark Matter, a new kind of matter that does not interact with light. [1:04:14]

The topic of this video module is genetic basis for variation among humans. The main learning objective is that students will learn the genetic mechanisms that cause variation among humans (parents and children, brothers and sisters) and how to calculate the probability that two individuals will have an identical genetic makeup. [32:01]

This BLOSSOMS lesson will help students conceptualize the enormity of geologic time and learn about important events in Earth's history. Students will also learn how geologic time can help explain seemingly incomprehensible processes. [22:00]

One of the main problems facing Saudi Arabia and many other countries in the region is the movement of sand, which threatens the urban areas. With the expansion of new installations and other projects, sand dune movement is costing governments a lot of money and energy. We shall shed some light on this problem and introduce students to some basic knowledge about this issue. [29:14] (English Subtitles)

This video lesson will present Gravity Assist, or what is wrongly referred to as the gravitational slingshot. Gravity assist is a maneuver performed by interplanetary spacecraft to travel farther on less fuel. It is a classic exercise in Newtonian mechanics. [37:49]

This video lesson highlights how science can be learned from daily life experiences. It emphasizes the ways in which simple laws of physics can be understood from personal observations and experiences, and in fact it demonstrates that we use these laws as if they were built into our instincts. The video also introduces Newton's laws of motion. [41:37]

This video lesson uses the technique of induction to show students how to analyze a seemingly random occurrence in order to understand it through the development of a mathematical model. [41:24]

The goal of this lesson is for students to understand just how many particles Avogadro's Number truly represents, or, how big a mole really is. [19:02]
