Physical Science A

Bellwork:
    1.  What is simple harmonic motion?
   
    2.  What will happen to the speed of a light wave as it passes from a gas into a liquid?

    3.  IF a wave has a frequency of 35 Hz and a wavelength of 4 meters, what is the speed of the wave?      What is the period?

    4.  A wave traveling at 120 m/s has a wavelength of .5 meters, what is the frequency of the wave?  The     period?


Check and go over the homework.

Quiz over wave speed problems.

Discuss Sound, sound classifications, and sound interactions

HW: Using the Phet website, answer the sound interaction worksheet.

Physical Science B

Bellwork:
    1.  What biome is characterized above average precipitation part of the year and the other part of the year     is a relatively dry.

    2.  Which of the biomes would we find permafrost?

    3.  Where would you typically find a whitetail deer?

Objectives:
1.  Understand the factors that affect the populations of organisms.

2.  Understand and explain the differences between exponential growth and logistic growth of a population.  Also, be able to explain what factors would contribute to these types of growth.

Discuss populations.
