Lab 1

Background: One of the most important steps that a scientist completes during an experiment is data processing and presentation. Data can be analyzed by the presentation of the data in table format (data table), or the processing of that data through graphical manipulation to visually discern the differences in the variables tested. Analyzing Data: The graph shows the number of shrimp hatched at different temperatures. 40 30 20 10 17 18 19 20 21 22 23 24 Temperature (Celsius) 1. What is the Independent (manipulated) variable? 2. What is the Dependent (responding) variable? 3. How would you summarize or caption this graph? In one sentence, connect the two variables. Number of Eggs

Write a summary: Simply put, a lab report is a way to explain what you have done in an experiment. You describe theresults you obtained and then discuss what you learned. There are several ways to write a lab report,and depending on your class or your instructor, the requirements will vary. But this guide is to helpyou understand the reason why writing a lab report is an important part of the science process. It willalso introduce the basic structure of one type of write-up.In college, any science course you take will require you to do a lab report. But they are not just busywork. They actually serve a purpose. You see, a written report is one of the main ways to share information to other scientists. It communicates the major points of an investigation to others who are ina similar field. This is a systematic way to spread information!Lab reports have their own unique style and format, too. Though you may have been taught to writepoetically and with artistry, lab reports require…

Leonardo da Vinci's Vitruvian Man Leonardo da Vinci's Vitruvian Man shows how the proportions of the human body fit perfectly into a circle or a square. With these proportions, your arm span (distance from fingertip to fingertip) should be equal to your height (distance from head to heels). In this laboratory exercise, you will see if this is true! In this activity you will explore the legitimacy of Vitruvius' theory by developing a hypothesis regarding the Vitruvian Man. Background Information Leonardo da Vinci, a famous Italian renaissance inventor and painter, was greatly influenced by a man named Vitruvius. Vitruvius was a Roman engineer and architect during the first century B.C. Vitruvius discovered a formula to model what he thought were ideal proportions for a man. Da Vinci used this ideal model when drawing the Vitruvian Man in about the year 1490. The drawing shows a man standing in a square, which is inside a circle. The man has two pair of outstretched arms and two pair of…

What are the key features of biological measurements that biologists must consider when quantifying and describing living things?  Choose all that apply.   Question 5 options:   Scale   Scale, type of data and measurement do not need to be considered at all.   Type of data    Measurement error

answer is incorrect

Complete the following sentence so that it is correct: Scientific theories are based on...

Experiment with fish tank and algae   Design an experiment with the scenario described below. The scenario gives you the observation.  Please label your question, hypothesis, predication, and how you would design your experiment. You have access to any materials that you need for your experiment. Include a label for the standardized controls, independent variable, and dependent variable.  You observe that your five-gallon fish tank that sits on your windowsill grows algae very quickly.

Design a (hypothetical) experiment that adheres to the Scientific Method. Be sure to include all the necessary requirements at each step and give examples at all of the steps. Start with an observation, whether it's real or made up, state the null hypothesis, and design an experiment (including an experimental and control group, random sampling, sample size, and reproducibility) that will allow the student to reject or fail to reject the hypothesis, and state (hypothetical) 'actual' results and the appropriate conclusion to draw from those results.

(1 question with multiple steps please answer) Identify the component characteristics of a scientific investigation Suggest alternative hypotheses that could be tested by the design Evaluate the validity of conclusions based on the given results Suggest ways to improve the experimental design Define and recognize examples of the experimental group, experimental variable, control group, control variable, independent variable, and dependent variable, and data

You are designing an experiment to test the following hypothesis: Temperature affects the ability of students to think clearly, and, therefore, students in a hotter room will have lower exam scores than students in a cooler room. For your experiment, list the following Sample size Independent variable Dependent variable Control group Experimental group Standardized variables How will you ensure that you have a random sample?

Design a SI modeled, detailed , yet hypothetical, biology experiment of your choice. In clear terms lay out all parameters of the experiment, including all controls and variables. Make sure that you clearly indicate where each step of the SI process applies(observation, question, hypothesis, analysis etc

In way science is limited in its ability to gain knowledge? What is a hypothesis? What is a theory? Why is a scientific law? What are methods of logical thinking are applied in science? What are the two important characteristics of a hypothesis? What types of variables are included in an experiment? What is the importance of including a control group in an experiment? What is the main difference between basic and applied science? How are the two related? Why is critiquing important in science? Why must scientists publish their work?

1. If quantitative change were all that existed, what would a butterfly be?  What would a human being be?  First, think about how a butterfly and a human start out; then think of how that being would end up if only quantitative change existed.  Try your best on this question.  Remember that the professor provides the expected answer.  Do not copy an answer from students in previous semesters as this practice prevents true understanding of concepts.

Truth or false a lab journal or notebook is considered as scientific tool.

Imperial China during the Ming dynasty (1368-1644 CE) could conceivably have started the Scientific Revolution before Europe; its failure to do so might have resulted (at least in part) from each of the following factors except: foreign trade was dominated by the Imperial Navy, with no profit motive for merchants European sailing vessels of that time were much smaller than Chinese treasure ships Chinese religion was polytheistic, while the central government at that time was strong military expenditures were diverted from ship-building to land-based armed forces Chinese colleges were independently-chartered, not under Imperial control like Europe

List the three types of variables that are taken into account when designing an experiment, and briefly define each in your own wrods.

A controlled experiment O includes at least two groups, one differing from the other by two or more variables includes at least two groups, one of which does not receive the experimental treatment is repeated many times to ensure that the results are accurate includes one group for which the scientist controls all variables

Hey can you help me draw a graph showing these results and include a correctly labeled x and y axis. According to the the picture I have attached. Thank you so much your the best :) also side note: the data is trying to test if lizards eat more when it’s cool or hot out and this is how they decided to test it.

How should you test a hypothesis?
