Why Does it Get Colder on a Clear Night than a Cloudy Night?
Clouds are nature's insulator! A lab investigation asks learners to use an infrared thermometer to measure differences in infrared temperatures. They find that pointing the thermometer at a cloud has a much different result than pointing...
Cornell University
Light Waves: Grades 6-8
Explore the behavior of light with different materials. Collaborative groups determine whether certain materials absorb, reflect, diffract, or transmit light waves. They then measure the angle of incidence and angle of reflection.
