2013 Diffusion Lab Research Question: How does the amount of water in a beaker affect the rate at which food coloring diffuses to the bottom of the beaker? Independent Variable: Height of water in beaker (Inches) Dependent Variable: Rate of diffusion (seconds) Controlled Variables: * Size of beaker * Temperature of water (23°C) * Type/color of food coloring * Person Timing * Environmental conditions Materials: * Beaker(well over 4 in tall) * Food coloring * Tap

Biological vs Chemical Pest Control All living things strive to survive‚ but unfortunately the needs of other creatures sometimes conflict with our needs. An example of this conflict is the struggle between pests and humans.

Biological Level of Analysis Learning Outcomes 1. Outline the principles that define the biological level of analysis. a. Patterns of behavior can be inherited: There is innate behavior “hard-wired” in organisms that is carried on through genetics. It makes certain stimuli generate certain response and is usually evolutionary. b. Animal research may inform our understanding of human behavior: Biological analysis of animal behavior can be used to predict similar results in humans
