We were scheduled to take an end of the unit test on Heat, Sound, and Light energy this Thursday. Since the kids haven't had a good opportunity to study this past week, I'm going to move the test to Monday. We'll take some extra time to review concepts today and tomorrow, and I'll even read to them the entire test tomorrow, so they won't be caught off-guard and they'll know exactly what to study. Doing it this way will also give the children something to do with their brains over the three day weekend. Since the second quarter ends tomorrow, this test will count towards their third quarter grades. You can help your child prepare for the test by practicing the vocabulary in the right sidebar, and by discussing the following questions:
Does sound travel fastest through solids, liquids, or gases? Why?
Why is there no sound in outer space?
Why does a smaller instrument part, such as the skinny strings on a guitar, make a higher pitch? Why does a larger part, such as the big keys on a xylophone make a low pitch sound?
What are the colors of the visible spectrum and their order in the rainbow? HINT: ROY G BIV!
Which colors have the higher frequency and which have the lower frequency?
Does light travel faster through gases or liquids? Why
Is it better to wear white clothes or black clothes on a hot day? How about a cold day? Why does the color of your clothes matter?
