Population Density Around Rivers

We covered a lot of material today:

  • Started by studying for TOMORROW'S GOVERNMENT QUIZ.
  • Labeled the parts of a river:
  • Had a student act out the river.  (Mouth at the end... delta formed at the mouth)
  • Had ancient civilizations formed around the river
  • Discussed the difference between population and population density while students were in the taped off boxes.
  • Did some population/population density (basic) math problems
  • Watched a video about a snake: point?  The mouth is at the end.

So often, students confuse source and mouth.  Which one is the beginning?  Which one is the end?  The mouth is at the end.  The source is at the beginning.  (Think of the source of a problem...  You're trying to think of the beginning of a problem.)

If you've read and discussed this post with an adult, explain to them the difference between population, and population density.  Then, write down your explanation.  Have the adult sign the paper.  Turn it in tomorrow for extra credit.  Make sure your name, date, and hour are on it.

Here's the winning group for the year: 4th hour.  We fit 30 people in here.  The all-time record still stands at 33.  We almost had it, though.
