Faith Eno Daphnia lab report Abstract The importance of this experiment is to better understand how the water flea reacts to the solutions alcohol and caffeine. The experiment begins with taking the dapnia and securing it onto a slide. A team of two people where one will count the heart beats and one keep track of time will measure the BPM of the Daphnia throughout. The control is the first to be measured in beats per minute with brief breaks to change out the water. Then the variables alcohol, caffeine, and the experimental solution are measured with brief breaks to change out the concentrations of the solutions (alcohol 1%, 3%, and %5 ;Caffeine 1% and 2%) rest the water flea in water.

Independent and Dependent Variables An independent variable is a factor that is manipulated in an experiment.? The experimenter controls whether or not subjects are exposed to the independent variable.?? The dependent variable is measured to determine if the manipulation of the independent variable had any effect.? For example,?? to test a hypothesis that eating carrots improves vision, the experimenter would manipulate whether or not subjects ate carrots.? Thus, eating carrots is the independent variable.? Each subject?s vision would be tested to see if carrot eating had any effect.? Thus, vision is the dependent variable.? The subjects assigned to eat carrots are in the experimental group, whereas subjects not eating carrots are in the control group. ?

Chapter Two What is science? Science: ? is a methodical, logical process for producing knowledge about natural phenomena ? a cumulative body of knowledge ----- Table 2.1 : Basic Principles of Science (7) Science depends on skepticism and accuracy ? Ideally scientists are skeptical and un biased. ? Scientist strive for ? Accuracy- correctness of measurement ? Reproducibility- Repeatability of result : Repeating studies or tests is called replication Deductive and inductive reasoning ? Deductive reasoning- logical reasoning from general to specific ? Inductive reasoning- reasoning from many observations to produce a general rule ? It is also important to recognize the role of insight, creativity, aesthetics, and luck in research

What Makes a Worm?s Heart Race? Part 1 - Learning Name: Hour: Date: Purpose: To explore the impact of treatments on the pulse rate of the worm Lumbriculus variegatus while refreshing and refining your understanding of experimental design with a focus on recognizing and minimizing experimental bias. Objectives: Upon completion of this activity, you should be able to: Count pulse rate in blackworms (Lumbriculus variegatus). Demonstrate the ability to design and perform an experiment using the strong inference model and multiple hypotheses with attention to the minimization of experimental bias. Demonstrate an understanding of graphing and the use of simple statistical data analysis to evaluate the impact of an experimental treatment.

Experimental Paper (Study #3) Emily McDonagh Psychology Period 3 Riolo ?One problem facing Carmel High School is the number of illegal underclassmen uptown. Presently if a student is found uptown they are placed in school suspension. This has not been affective. Therefore the new policy will be making the student clean up the uptown area everyday (under supervision) for three days for each offense.?

Tire Pressure Problem: How the temperature of water affects plant growth. Observations. These days we are running out of everything so I think that we should improve the speed and the size of the plant. So by putting different temperature soils in the plant it should probably make the plant bigger. Hypothesis: If the plant is put in the cold soil, then the plant will increase its rate of growth IV C DV Chart: Independent Variable (IV) Constants Dependent Variable (DV) Temperature of water Cold (15 degrees C) Regular (25 degrees C) Amount of light Plant Growth Amount of soil Type of soil Type of water Amount of water Type of enviorment

Chapter 2 Experimental Design Definitions: 1) Observational study - observe outcomes without imposing any treatment 2) Experiment - actively impose some treatment in order to observe the response I?ve developed a new rabbit food, Hippity Hop. Rabbit Food Makes fur soft & shiny! Increases energy! 100% of daily vitamins & essential oils! Can I just make these claims? What must I do to make these claims? Who (what) should I test this on? What do I test? NO Do an experiment Rabbits The type of food 3)Experimental unit ? the single individual (person, animal, plant, etc.) to which the different treatments are assigned 4) Factor ? is the explanatory variable 5) Level ? a specific value for the factor 6) Response variable ? what you measure
