The STS-135 Crew Participates in Interviews
The STS-135 crew members talk with representatives of WBNG-TV and WICZ-TV in Binghamton, N.Y., near Pilot Doug Hurley's home town of Apalachin, and KGO-TV of San Francisco. Mission Specialist Rex Walheim is from nearby San Carlos.
By making and testing simple balloon rockets, students acquire a basic understanding of Newton's third law of motion as it applies to rockets. Using balloons, string, straws and tape, they see how rockets are propelled by expelling gases, and test their rockets in horizontal and incline conditions. They also learn about the many types of engineers who design rockets and spacecraft.
Episode 63: Parental Angst and Acceptance in the Digital Age
Drs Mike Arnold and Martin Gibbs discuss the impact on families of the seemingly unstoppable wave of digital and virtual communications technologies.
MOSFET 2 - Introduction to Microelectronic Circuits
Introduction to Microelectronic Circuits - Spring 2006. Fundamental circuit concepts and analysis techniques in the context of digital electronic circuits. Transient analysis of CMOS logic gates; basic integrated-circuit technology and layout.
Tires and ecosystems
Tires are one of the worst things that can be thrown into a landfill. They take up a lot of room and they can collect rainwater that is a prime breeding ground for mosquitoes. Tires can be repurposed, or used for other purposes, such as tire swings and playground toys. They can also be recycled and used to make school gym floors and shoes.
The tarsier is a type of primate. It is a consumer because it cannot make its own food and must eat other organisms to get energy. Tarsiers are carnivores, meaning they eat other animals to gain energy. Tarsiers have a diet that includes birds, insects, and snakes.
How Do Things Fall? Activity
Students learn that it is incorrect to believe that heavier objects fall faster than lighter objects. By close observation of falling objects, they see that it is the amount of air resistance, not the weight of an object, which determines how quickly an object falls.
6.542J Laboratory on the Physiology, Acoustics, and Perception of Speech (MIT)
The course focuses on experimental investigations of speech processes. Topics include: measurement of articulatory movements, measurements of pressures and airflows in speech production, computer-aided waveform analysis and spectral analysis of speech, synthesis of speech, perception and discrimination of speechlike sounds, speech prosody, models for speech recognition, speech disorders, and other topics.

What is Heat?
"In Physics, heat is not in inside an object, but heat is the transfer of energy from one object to another so when you touch an object and it feels hot, what you're feeling is the heat you're feeling the energy being transferred from that hot object to your hand." (01:09)
