AP Biology Lab #1 Animal Behavior The Effect of Different Stimuli on the Behavior of Pill Bugs Asif Sheikh 09/03/13 Mr. Perry ? 5th Period Abstract There were three main purposes for the experiment of placing 10 Pill Bugs in choice chambers with different environmental conditions for 10 minutes. First: to observe and record the behavior of the Pill Bugs, then to expose the Pill Bugs to two different scenarios, wet vs. dry and acidic vs. basic, to determine which environment they preferred. Second: to prove that the Pill Bugs preferred wet conditions over dry and acidic conditions over basic condition. Third: to prove that Pill Bugs displayed taxis behavior in both scenarios.

Chapter 24 Outline Economic Systems and Sustainability A. An economic system produces and distributes goods and services by using natural, human, and physical resources. 1. An economic system produces, distributes and consumes goods and services. 2. Three types of resources are used to produce goods and services, natural resources, human resources (labor and skills), and physical or manufactured resources (tools, machinery, etc) B. A purely free-market system is a theoretical ideal where buyers and sellers interact in markets without interference by government or other interference. 1. In the ideal, all economic decisions are governed by demand and supply and price.

Daniel Seo 10/10/13 Period 5 Chapter 6 Thermochemistry Outline 6.1 The Nature of Energy 1. Energy ? capacity to do work (or to produce heat) i. Work ? force acting over a distance (moving an object) ii. Heat ? form of energy. ? chemicals may store potential energy in their bonds that can be released as heat energy 2. The law of conservation of mass ? energy can be converted from one form to another, but cannot be created or destroyed ? is also the first law of thermodynamics. i. Potential energy ? energy due to position or composition ii. Kinetic energy ? energy due to the motion of an object ? K? = 1/2mv2 3. Temperature reflects random motion of particles in a substance 4. Temperature indicates the direction in which heat energy will flow

Warm-Up Your car's gas tank holds 18.6 gallons and is one quarter full. Your car gets 16 miles/gal. You see a sign saying, "Next gas 73 miles." Your often-wrong brother, who is driving, is sure you'll make it without running out of gas. You're not so sure and do some quick figuring: Matter and Change Matter: Anything that has mass and takes up space. Mass: measure of the amount of matter. Matter and Change Atoms: Smallest unit of an element that maintains the properties of that element Elements: pure substance made of one atom. Compounds: made of atoms of two or more elements that are chemically bonded Physical properties and changes Physical properties: quality or condition of a substance that can be observed or measured without changing the substance
