]]> Barometric pressure is responsible for much of our weather. In this episode, I travel to Hawaii so we can explore the relationship between barometric pressure and temperature.

Host: Michael Doig
Duration: 4:11

Materials

Can of Compressed AIr – Can be purchased at any office supply store for around $6.

Raytek MT4 Mini Infrared Thermometer – The ability to take the temperature of just about anything without touching it is amazing, not to mention entertaining. I took a reading of my desklamp and found out the bulb was 212?F, Wow!

Casio Men’s Pathfinder Triple Sensor Altimeter/Barometer/ Digital Compass Watch – For the money, this watch is a steal. Barometer, compass and thermometer all in one place. Great for hiking or scientific exploration. The manual is really dense, but operating the watch was relatively easy. My biggest problem was with the temperature, it was constantly bouncing around.

Barometric Pressure Fast Facts

  • A column of air one square inch in cross-section, measured from sea level to the top of the atmosphere, would weigh approximately 14.7 lbs per square inch or 1013.25 mb.
  • An increase in elevation results in a decrease in barometeric pressure.
  • As pressure decreases, temperature also decreases.

Special thanks to Mike Ogasawara and David Doig.

Weathering Fast Facts

  • Weathering is the mechanical and chemical breakdown of rocks and minerals, eventually creating soils.
  • Chemical weathering reactions include carbonation, hydrolysis, oxidation, solution and hydration reactions.
  • Biologically produced chemicals, such as those produced by lichens and mosses, can also break down rocks.

]]> planning idea
In response to Dan Meyer’s Where is Your List?, I put together this collection of science related animations, movies, and interactive modules. This list features resources I find valuable and have used either in a PowerPoint presentation or as a stand alone example. I still like to keep science real, but sometimes an animation can bring a topic to life in ways a text or lecture can not.
1) Radiation & Conduction
2) Atmospheric Layers
3) Big Bang
4) Plate Tectonics
5) Earth Rotation
6) Sun Motions
7) The Seasons
8) Pangaea Breakup
9) Polar Sea Ice Melting
10) Lunar Landing
11) Making a Topographic Profile
12) Convection Currents
13) Density
14) Seismic Waves
15) Volcano animation: Mt. Kilauea
16) Minerals
17) The Rock Cycle
18) The Water Cycle
19) Land Slide

Host: Michael Doig & John Herrera
Duration: 3:15

Materials

  • Car
  • Helium Balloon
  • Open Road

Convection Fast Facts

  • Lighter than air gases move from areas of high pressure toward areas of low pressure.
  • The highest air pressure is near the surface of Earth.
  • As you increase your altitude/elevation air pressure decreases.
