• Investigation: Scientific Process And Lung Capacity
  Are these two events connected? Any laboratory procedure you follow without a hypothesis is really not an experiment. It is just an exercise or demonstration of what is already known. How Are Hypotheses Written? Salt in soil may affect plant growth. Plant growth may be affected by the color of the light. Bacterial growth may be affected by temperature. Ultra violet light may cause skin cancer. Temperature may cause leaves to change color. However, their form is not particularly useful. If these statements had not been written carefully, they may not have even been hypotheses at all. For example, if we say "Trees will change color when it gets cold. Or if we write, "Ultraviolet light causes skin cancer. One way to prevent making such easy mistakes is to formalize the form of the hypothesis. Formalized Hypotheses example: If skin cancer is related to ultraviolet light , then people with a high exposure to uv light will have a higher frequency of skin cancer.

  If leaf color change is related to temperature , then exposing plants to low temperatures will result in changes in leaf color. Notice that these statements contain the words , if and then. They are necessary in a formalized hypothesis. But not all if-then statements are hypotheses. For example, "If I play the lottery, then I will get rich. In a formalized hypothesis, a tentative relationship is stated. For example, if the frequency of winning is related to frequency of buying lottery tickets. If you always ask yourself that if one thing is related to another, then you should be able to test it.

  Formalized hypotheses contain two variables. One is "independent" and the other is "dependent. An acceptable hypothesis contains both aspects, not just the prediction portion. Investigation 1: Conducting a Biological Experiment Purpose: to learn how to use the scientific method by conducting an experiment. You have learned so far that scientists use the "scientific method" in solving problems. Each lab group will Set-up both experiments; pages 4 and 5 of the lab manual. During the next week each lab group will collect data in tables. Once the data is collected your group will have to summarize the data and represent the results using a table and figure. Step 1: Introduction material before beginning an experiment. Refer to page 4 of your lab manual for a description of the experiment.

• The Scientific Method
  Investigation: Scientific Process and Lung Capacity Part 1: Background Information Often, we think of science as something that only happens in laboratories where people where white lab coats and safety glasses. In reality, scientific processes are performed every day, by everyone. It's the process you go through when you try to solve a problem, like "Why isn't my car starting? Most scientists agree to a common language of problem solving called "The Scientific Method," which is often described as a step-by-step methodology for solving problems. To be fair, there are many different ways to practice science, and not all of them use this procedure. Part 2: The Task You will use the scientific method to answer a question about human lung capacity. The volume of air in your lungs can be measured with a spirometer, which measures the air inhaled in mL milliliters.

  Lung volume for an adult human is about mL, though not all the space is used for gas exchange. The maximum usable capacity of the lungs is called the vital capacity. There are many factors that could explain variations in the vital capacity of any two individuals. Objectives: To develop scientific reasoning skills To formulate hypotheses and arrive at conclusions To establish that the most reasonable explanations for natural phenomena are those that are supported by evidence Materials: Spirometer and mouthpieces, calculators, meter sticks or tape measures Safety considerations: Students who have respiratory issues should not participate. If you at any time feel lightheaded, discontinue tests. Part 3: The Experiment 1. Make observations.

• Writing A Lab Report: (The Scientific Method In Action Part 3)
  Have several members use the spirometer. Was everyone's vital capacity the same or were there variations? Ask a question. Discuss wording for a causal question about your observations. State a question related to lung volume and observations. Form a hypothesis: What factors do you think have a causal relationship with lung capacity. Factors could include variables like size of the person or overall fitness of the person. Class Prediction: Half of the class will be testing size as a causal factor, and the other half will be testing overall fitness.

  Check your assigned prediction: If size is related to lung capacity, then larger individuals will have a greater lung capacity. Size will be measured as height in centimeters. If fitness level is related to lung capacity, then those with a higher level of fitness will have a greater lung capacity. Fitness will be measured by individual report on the level of activity, using a scale.

• Ensuring Lab Safety
  The scientific method is a process for experimentation that is used to explore observations and answer questions. Does this mean all scientists follow exactly this process? Some areas of science can be more easily tested than others. For example, scientists studying how stars change as they age or how dinosaurs digested their food cannot fast-forward a star's life by a million years or run medical exams on feeding dinosaurs to test their hypotheses.

  When direct experimentation is not possible, scientists modify the scientific method. In fact, there are probably as many versions of the scientific method as there are scientists! But even when modified, the goal remains the same: to discover cause and effect relationships by asking questions, carefully gathering and examining the evidence, and seeing if all the available information can be combined in to a logical answer. Even though we show the scientific method as a series of steps, keep in mind that new information or thinking might cause a scientist to back up and repeat steps at any point during the process.

  A process like the scientific method that involves such backing up and repeating is called an iterative process. Whether you are doing a science fair project, a classroom science activity, independent research, or any other hands-on science inquiry understanding the steps of the scientific method will help you focus your scientific question and work through your observations and data to answer the question as well as possible. Diagram of the scientific method. The Scientific Method starts with aquestion, and background research is conducted to try to answer that question. If you want to find evidence for an answer or an answer itself then you construct a hypothesis and test that hypothesis in an experiment. If the experiment works and the data is analyzed you can either prove or disprove your hypothesis.

  I then explain to students that they are each individually responsible for completing an individual lab report, and that the group as a whole must then come together to complete the group lab report. It requires each and every student to practice the writing skills in the targeted standards. It requires both self reliance completing your individual section and cooperation coming together to complete the group lab report. Individual Report Both the individual and group lab report worksheets provide scaffolds for organizing information. This description of a single task should include a detailed explanation of the procedure they followed, the data they collected, how that data proved or disproved their hypothesis, and how they might alter the specific task if they were to conduct the experiment again.

  Once students have all the necessary materials, I tell the group to split up their data and give the relevant data table to the student that will be writing about that task. If students were thorough in their completion of the data tables during the experiment, they should already have most of the information necessary to transfer the procedural explanations and collected data directly to the relevant sections of the lab report. I remind them that a scientific report should have enough detail that another scientist could conduct the experiment exactly as they did. If they reply that they only collected one kind or another, or if the data they did collect seems limited or irrelevant, I point that out and suggest they consider addressing that fact when they answer the reflective question about what they would do differently if they repeated the experiment.

  They then must identify the variables and groups of the experiment and provide short descriptions of the tasks they conducted. The final part of the group lab report requires them to state a conclusion about their hypothesis and support it with data collected during the experiment. I require students to write this conclusion as a multi-paragraph document on a separate paper and encourage them to use a basic 5 paragraph format with an introduction, support, and conclusion. Students may struggle with this section, but I try and point them back to the data if they get stuck.
