Educational research has shown that “pounding” concepts into students’ heads through lecture only does not result in positive student learning and long- term retention of the concepts This Should Do It!
Variety of Methods Many concepts in science are not well-understood so a variety of teaching methods are encouraged by educational researchers.
Demonstrations It has been shown that using Demonstrations in the science classroom helps students retain concepts, energizes the science classroom and is more fun!
color 1.What color is a ripe strawberry? 2.What color is a shadow? 3.What largest curved mirror ever made by man? 4.What is the most “perfect” curved mirror ever made by man? Light & Color Challenge
Radiometer converts light energy into motion (kinetic energy). UV Beads change color in ultraviolet light (sunlight, black light, etc.) What is Light? A Form of Energy? White sides reflect infrared radiation. Black sides get warmer by absorption. Air molecules striking the warmer sides take off faster and push back.
21 Polarization and 3-d These glasses are used for 3-d movies like “spiderman” & “Shrek 3-d” at universal studios.
What is the minimum size that a Plane mirror must be in order for a person to see their entire body? a.½ your height b.b. ¼ your height c.Your actual height d.1/3 your height e.It depends on your distance from the mirror Plane Mirror Challenge “The Science Teacher”
Just use the Law of Reflection! “The Angle of Incidence = The Angle of Reflection” Law of Reflection
? Whether you are close to the mirror......or a distance away from the mirror... The mirror’s size must be a minimum of ½ your height! Law of Reflection
29 Orbits at 380 miles above Earth. 42.5 ft in length/127 tons/1 inch to spare on each side in shuttle bay. Resolution… From Hancock Tower in Boston to the Washington monument in Wash. DC, Hubble could read “In God We Trust” in a dime!

32 Quote from NASA after viewing the images produced by their brand- new 1 billion dollar hubble telescope.
The Arecibo radio telescope is currently the largest single-dish “concave mirror” in the world. First opening in 1963, this 305 meter (1000 foot) radio telescope resides in a natural valley of Puerto RicoArecibo radio telescope Puerto Rico “Concave Mirrors” at Arecibo
Sunset on Mars On May 19, 2005, NASA's Mars Exploration Rover Spirit captured this stunning view as the Sun sank below the rim of Gusev crater on Mars. This Panoramic Camera mosaic was taken around 6:07 in the evening of the rover's 489th Martian day, or sol.

Radiometer converts light energy into motion (kinetic energy) UV Beads change color in ultraviolet light (sunlight, black light, etc.) Radiometer White sides reflect infrared radiation. Black sides get warmer by absorption. Air molecules striking the warmer sides take off faster and push back due to Newton’s 3 rd law!
All persons with “normal” vision should see a “12”.! Your Eyes and Color
Normal vision--> “7” Colorblind “nothing” Your Eyes and Color
Red/Green colorblind--> “3” Normal vision--> “8” Your Eyes and Color
Though humans can see the entire visible light spectrum and would be able to appreciate the rich greens of the grass in the meadow on the left, prairie dogs and squirrels are red/green color blind, and only perceive the blues, yellows, and grays of the landscape.
DOGS CAN SEE COLOR! It is a myth that dogs see a black and white world. Dogs see in color, but not the same way that we do. Veterinary ophthalmologists have determined that dogs are similar to people with red/green color blindness, so they can see bluish and greenish shades but not reddish ones. To a dog, a bright orange ball on a grassy lawn appears as a light greenish ball in greenish grass. Go fetch!
