To understand barometer readings, measure the air pressure using any type of barometer, and compare the pressure reading to the average air pressure of 29.92 inches of mercury. Find out how low pressure generally means bad weather and high pressure signifies good weather with information from a television meteorologist. Video is short and good quality and is appropriate for elementary level students of grades three through five. (02:01)

.Science experiments that can be done with a barometer should include taking barometer readings every day for two weeks and noting the different in weather during different periods of air pressure. This video also provides step by step instructions from a meteorologist on how to make your own barometer. More information on weather instruments, such as the barometer, can be found in the Meteorology subcategory inside the Earth Science portion of the directory. (02:38)

This is the 8th lesson in the series, "Physical and Chemical Change." This lesson explains air pressure at a microscopic level, demonstrates how to predict the effect of changing pressure, or temperature, on the volume of a given sample of gas, and explains how to recognise that equal volumes of gases at the same temperature and pressure contain the same number of particles. The video includes great demonstrations that are easy and inexpensive. These demonstrations are great for introducing gas laws (15:44).

Oceans contain 97% of the water on the Earth and are home to a huge number of living creatures. Most of these creatures, about 90% of them, live near the water's surface, where the pressure not so great and they can get some light. Learn more about our oceans with this slide show from StudyJams. Vibrant images are set to music while information is written under each photo.

This teacher-made project is a rap song about what fossil fuels are and how they are formed. Audio quality is low making it difficult to understand the words to the rap. Some of the lyrics include: "Well, it all starts a few million years ago from the mountains high to the valleys low. I've been talking to the bird and talking to the bees telling me all about the dead trees. They've been falling to the ground getting covered in soild and sand. It all builds up and there's loads of pressure. Dead trees you can't escape - I aint gonna let ya. Now I'm telling you from the bottom of my soul, them dead trees get turned into coal...." This video could also be used to inspire a student project/rap. Run time 01:43. Lyrics begin after 0:30.

Nov. 2010 - Dan Phillips of Phoenix Commotion, a recycled materials house builder, gives a TED talk about the building potential of construction waste materials and the potential in each of us to live better, more creative and fun lives by breaking away from consumer and cultural pressures in our purchasing choices and our lives.
Subjects covered include the sources of wasteful consumption:
-The human brain's desire to establish and define patterns can lead to wastefulness,
-Nietzsche philosophy of differences between Apollonian and Dionysian mindsets,
-Industrial Revolution promoting standardization which leads to greater waste,
-The myth of labor being more expensive than materials,
-Plato's notion of perfect form - our vision of 'perfection' is unreasonable and influenced by marketing and building interests.
In addition, the above is exacerbated by:
-Human tendency toward perceived expectations of what we think our peers think we should do with our lives. Philosophical reference - Sartre's divided self, and
-The shadow side of our natural gregariousness - humans tend to want to have what they perceive will make them special or important in the tribe.
Final thought - "We need to reconnect with who we REALLY are, and that is thrilling indeed."

This short video shows an experiment where water is drawn up into a container as the oxygen is burned off. The water rises because they're heating up the air inside the beaker. As the heat went out, the air pressure start pushing the water up. the beaker exploded because it had so much force, that it bounced on the table. Run time 03:59.

This short video quickly reviews facts about the physical and mental growth of teenagers. Such facts that most girls will start puberty around 9 years of age, and most boys will start around 11 years. By 15, most girls are completely physically mature, as are most boys at nearly 17. However, research has shown that the adolescent brain does not mature at the same rate as the body.The prefrontal (anterior) part of the brain controls reason, emotion, common sense, and judgment, and is not mature until nearly 21 years of age. Thus teenagers are somewhat vulnerable to peer pressure and the media as they may not be able to process the impact of their decisions. A good video for middle school students, but needs to be the start of a discussion, not an end in itself. (01:15)

This NASA video segment explores how Newton's second law applies to the thrust force on an airplane. Viewers watch an instructor at NASA's National Test Pilot School and learn that an airplane's engines work to change the horizontal momentum of the air surrounding the airplane. Viewers also learn that this change in momentum is accomplished through increased propeller speed, increased propeller diameter or increased air pressure in the jet engines. Onscreen formulas and calculations represent the forces mathematically. For example, in one part, the instructor uses Newton's second law to derive an equation to find the minimum rpm's needed to provide enough thrust to an airplane.

This educational video shows Oklahoma's largest tornadoes in recent
history. A tornado is a violently rotating column of air that rotates
while in contact with both the surface of the Earth and a cumulonimbus
cloud or, in rare cases, the base of a cumulus cloud. They are often
referred to as twisters or cyclones,[1] although the word cyclone is
used in meteorology to name any closed low pressure circulation.
Tornadoes come in many shapes and sizes, but they are typically in the
form of a visible condensation funnel, whose narrow end touches the
earth and is often encircled by a cloud of debris and dust. Most
tornadoes have wind speeds less than 110 miles per hour (180 km/h), are
about 250 feet (80 m) across, and travel a few miles (several
kilometers) before dissipating. The most extreme tornadoes can attain
wind speeds of more than 300 miles per hour (480 km/h), are more than
two miles (3 km) in diameter, and stay on the ground for dozens of miles
(more than 100 km). (49:48)
