Lab 1-The importance of plants What is the key factor to success in Biology 1401 lab? ATTENDANCE Define energy pyramid and understand its components and energy transfer. IT ILLUSTRATES THE RELATIONSHIP OF THE DIFFERENT TROPHIC, OR EATING, LEVELS WITHIN AN ECOSYSTEM AND THE ENERGY FLOW FROM ONE LEVEL TO THE NEXT. MOST OF THE ENERGY IS LOST AS HEAT. ONLY 10% OF AVAILABLE ENERGY IS TRANSFERRED TO THE NEXT LEVEL. What is the difference between producers and consumers? PRODUCERS ARE ORGANISMS THAT ARE ABLE TO TRAP SOLAR ENERGY AND CONVERT IT INTO ORGANIC MOLECULES. CONSUMERS ARE ORGANISMS THAT CONSUME ORGANIC MATTER FOR ENERGY. Define ecosystem. What is the difference between biotic and abiotic? ECOSYTEM IS A MAKEUP OF ALL BIOTIC AND ABIOTIC FACTORS WITHIN AN ENVRONMENT AND HOW THEY INTERACT WITH ONE ANOTHER.BIOTIC IS THE LIVNG COMPONENTS OF THE ECOYSTEM THAT INCLUENCE THE TYPES OF BIOTA INHABITING AN AREA. ABIOTIC IS NONLIVING COMPONENTS OF THE ECOSYSTEM THAT INFLUENCE THE TYPES OF BIOTA THAT CAN INHABIT AN AREA. Lab 2-Research methods What are the steps in the scientific method? What are the requirements for scientific inquiry? 1. MAKE OBSERVATION 2. STATE KEY QUESTION 3. STATE HYPOTHESIS 4. CONDUCT CONTROLLED EXPERIMENT 5. ANALYZE RESULTS 6. FORM CONCLUSION NULL AND ALTERNATIVE HYPOTHESIS, INDEPENDENT AND DEPENDENT VARIABLES, CONTROL AND EXPERIMENTAL GROUPS, Define independent , dependent, and control variables. INDEPENDENT VARIABLE-THE CONDITION THAT IS BEING EVALUATED FOR ITS EFFECT ON THE DEPENDENT VARIABLE (ex. Sulfur) DEPENDENT VARIABLE-THE CONDITION BEING EFFECTED BY THE INDEPENDENT VARIABLE (ex. Leaf color)

CONTROLLED VARIABLES-ALL OTHER CONDITIONS THAT COULD AFFECT THE RESULTS BUT DO NOT BECAUSE THEY ARE KEPT CONSTANT.(ex. All 20 plants planted in the same size pots, same amount and type of soil, placed on a windowsill with the same light exposure). What is the difference between null hypothesis and an alternate hypothesis? Be able to identify these in all labs. THE NULL HYPOTHEIS STATES THAT WHATEVER TREATMENT YOU USE IN AN EXPERIMENT WILL HAVE “NO EFFECT”. (ex. Adding fertilizer will not make plants grow taller). THE ALTERNATIVE HYPOTHESIS STATES WHAT EFFECT YOUR TREATMENT MAY HAVE. (ex. Adding fertilizer will make plants grow taller). What is the difference between control group and experimental group? CONTROL GROUP-THIS GROUP RECEIVES NO EXPERIMENTAL TREATMENT AND ALL FACTORS WILL BE HELD CONSTANT EXPERIMENTAL GROUP-THE GROUP RECEIVING EXPERIMENTAL TREATMENT THAT HELP TEST THE ORIGINAL HYPOTHESIS What is the primary unit of measurement used by scientists? What is a statistical t-test used for? CENTIMETERS A T-TEST IS USED TO COMPARE MEANS. IT ALSO GENERATED P-VALUE What is p-value? What should the p value be in order to accept your null hypothesis? What should the p value be in order to accept your alternate hypothesis?
