Darkness is simply the absence of light, which is a form of wave energy. We examined the electromagnetic spectrum.
We took advantage of the sunny day to examine how light (our next unit) is tied to heat by wearing shirts that are half black and half white. Which side got hot first? Why?
What is better than one sound quiz? Three of them, all in one day, of course!
Sound is a vibration, and we made plenty of that with our tuning forks today as we explored intensity and pitch.
With two parts of a straw we successfully made some of the most obnoxious noise makers available in the classroom (and beyond). Pitch was adjusted due to the differences in the straws, and intensity was adjustable as well. We also played music with root beer bottles and wine glasses filled with water.
Sound is a disturbance through a medium as a wave. We also played a game trying to figure out "What Sound is That?"
We tested our knowledge about heat transfer with a review and a unit test (or two!)
Heat transfers, and we used science to test Goldilock's claim that Papa's bowl was too hot, Mama's was too cold, and Baby Bear's was just right. Honestly, how are we supposed to trust someone who illegally trespasses, steals food, vandalizes furniture, and then loiters in Baby Bear's bed?
We enjoyed some more demonstrations of heat transfer and temperature measurement today.
We learned about conduction today through a number of class demonstrations. Hot stuff!
Bill Nye instructed us on the three forms of heat transfer today.
