1.1.2 Pre-natal diagnosis
This Unit looks at three different uses of genetic testing: pre-natal diagnosis, childhood testing and adult testing. Such tests provide genetic information in the form of a predictive diagnosis, and as such are described as predictive tests. Pre-natal diagnosis uses techniques such as amniocentesis to test fetuses in the womb. For example, it is commonly offered to women over 35 to test for Down's syndrome. Childhood testing involves testing children for genetic diseases that may not become a p
Living With Amnesia: The Hippocampus and Memory
Amnesia appears in many different forms. This module shows how the extent and location of damage can result in varying levels of memory impairment. Footage of Mike, an amnesic individual, demonstrates the result of an injury to the hippocampus. Mike’s reaction to his memory deficit and drastic coping measures underscore the importance of memory to everyday functioning.
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
Apollo: Reflections and Lessons
In this first of three AeroAstro symposium events to mark the 40th anniversary of the moon landing, an extraordinary cast of luminaries recount the parts they played in the Apollo program, and celebrate MIT’s unique role in getting humans to the moon.
Theodore Sorensen believes President Kennedy chose him t
Thinkwell Chemistry: Finding Empirical and Molecular Formulas, Part 1 of 2
This is a clip from a larger segment on how to find empirical and molecular formulas. (06:07)
This site provides online simulations, learning modules, and interactive tools for learning about nanotechnology -- the design and production of structures, devices, and systems one atom or one molecule at a time. Analyze the electronic properties of different nano materials and the optical properties of nanoparticles. Explore molecular conduction, nanofluids, and nanowires. Create simulations of nanoelectronic and nanoelectromechanical systems. Registration required.
How to Make a Miniature Volcano
Making a miniature volcano is simple by mixing in a small container baking soda, a bit of dish soap and vinegar that has been dyed red. See this volcanic chemical reaction with a demonstration from a science teacher in this video. Run time 02:05.
Process Of Burning a Diamond
Describes the periodic law in terms of the reaction of certain elements. Demonstrates that even diamond can react and form a gas. Video shows the burning of the diamond and explains why Mendelev placed both silicon and carbon in the same group. Grades 7-12. Includes closed captioning. 2:46 min.
The Oxidation States of Uranium
Shows the oxidizing of uranium, and the reaction of uranium 4 with nitric acid. Video clearly shows changes to the the uranium in the reactions. Grades 7-12. Includes closed captioning. 1:08 min.
The Law of Action and Reaction: Newton's Third Law
The Law of Action and Reaction: Newton's Third Law This NASA video segment explores how Newton's third law of motion applies to aerospace.
Where Do You Get Your Energy
Cells extract energy from sugar to produce ATP, the molecular fuel that powers all life processes. This interactive activity adapted from the Exploratorium delves into the processes that enable cells to unlock the energy contained in the foods we consume. We often use the term "energy" as an informal shorthand for our ability to stay alert and complete tasks. In fact, the presence of energy-rich molecules and our cells' ability to obtain, process, and use this energy is critical to life.
On the Surface Surface science examines how surfaces react with each other at the molecular level. The atoms at the surface are different than those atoms in the center of an object, making the atoms much more reactive than those inside. This program explores a variety of real world applications of this particular property.
