Mrs. Scaggs' Science Class



This document describes how detailed and complete each section of your science fair website should be. Your website should have the following headings and content for your four pages:Page 1:HomeSub-HeadingsOverview, Question, Hypothesis, Variables, and ControlsPage 2:ExperimentSub-HeadingsMaterials and ProcedurePage 3:DataSub-HeadingsData Table, Results, and GraphPage 4:Conclusion Sub-HeadingConclusionThese headings should all be the same format, size, and font as each other. They should be consistent throughout your project. They should be easy to see and read and should clearly distinguish the different sections of your pages. Your pages will go in this order of the page names listed above. Everything needs to be done digitally for your project. Graphics/pictures should be used when available to enhance the appearance of your site. Proper website design principles should be applied to all pages of your site. For some basic tips, see Mrs. Scaggs’ Advanced Technology site and watch the three videos under “Website Design Principles” at: . Page 1: Home PageTitleThe title of your website should be “Your First Name’s Science Fair Page”. The title of your project should appear in quotes at the top of your homepage. Do NOT include your last name, or anything that would identify you or where you live on your website; as it can be seen by anyone in the world! Be creative you’re your title. Try to catch people’s attention. Your title should NOT be a complete sentence, rather, a short phrase or word. Remember, as in book titles, your title should have the appropriate words capitalized. In the sample below, the title is “Chemical Volcanos”.OverviewYour homepage should contain a short introduction to your science fair project. The goal is to let people know the basic content of your site and provide a good “hook” to make them want to read about your experiment. A sample is provided below; however, you should include the sub-heading, “Overview” before you launch into the introduction.104775171450QuestionThe second sub-heading of your home page is “Question”. It is important that the first letter of each sub-heading is capitalized. The text of this section will simply be your question. Use the feedback from the paper you handed in entitled, “Final Submission of Question, Hypothesis, and Variables” to help you write the best version of your question. Be sure to use proper punctuation, spelling, and grammar.HypothesisThe third sub-heading of your home page will be “Hypothesis”. It is important that the first letter of each sub-heading is capitalized. The text of this section will simply be the statement of your hypothesis. Use the feedback from the paper you handed in entitled, “Final Submission of Question, Hypothesis, and Variables” to help you write the best version of your hypothesis. Remember, a hypothesis is a statement of what you predict the outcome of your experiment will be: in other words, the answer to your question. It is not an explanation as to WHY you think the outcome will be such. You will save the WHY for your discussion and conclusion. Be sure to use proper punctuation, spelling, and grammar.VariablesThe fourth sub-heading of your home page will be “Variables”. Since there are several types of variables in an experiment following the scientific method, you will have “Variables” as the main sub-heading in this category with two minor sub-headings: Independent Variable and Dependent Variable. Use the feedback you received on the paper you handed in entitled, “Final Submission of Question, Hypothesis, and Variables” to write each part.Independent Variable – You will have only one independent variable. Your independent variable should have the subheading “Independent Variable” and then a sentence beginning with “The independent variable in my experiment is . . “ Dependent variables - You will have only one dependent variable. Your dependent variable should have the subheading “Dependent Variable” and then a sentence beginning with “The dependent variable in my experiment is . . “ ControlsThe fifth sub-heading of your home page will be “Controls”. Use the feedback you received on the paper you handed in entitled, “Final Submission of Question, Hypothesis, and Variables” to write this. Your controls should be formatted in a bulleted list. You should capitalize the first letter of the first word for each point in your list of controls. Your list does NOT need to be in complete sentences, but in short phrases. Remember to list everything you will keep constant when testing each independent variable. Page 2: ExperimentMaterialsThe first sub-heading of this page is “Materials”. Make a bulleted list of all materials you will need to complete the experiment. Your bullet points used here should be the same style as you used for your controls on your home page. Be sure that for each material you list the quantity and the item with enough description for someone else to know exactly what to get. Please also remember that you write the amount of materials needed to perform one test, even though you will perform the test a minimum of three times. You will need to get three times as many materials as are in your materials list. ProcedureThe second sub-heading of your Experiment page will be “Procedures”. Make a numbered list of all the steps a person would have to go through if they were going to repeat your experiment. Don’t assume someone will know what to do unless you write it down. The first word of each step should be a verb and should be capitalized. This would be a great place to insert a slide-show of pictures of what you did, or upload a video of you demonstrating how you did your experiment. These are not required items, but would be an awesome way to take advantage of the neat things you can do with a website. Page 3: DataEveryone will have a different looking data table depending on your hypothesis and the experimental design you chose. For some of you, you won’t be able to make a data table, but will have a collection of observations instead. Some of you may have both. At the very minimum, you must have one or the other. Not having a data table is VERY rare, but is appropriate for certain questions. Please check with me if you are unsure what you should have. Data TableThe first sub-heading for this part will be either “Data Table” or “Observations”. If you have both types ofinformation, include a heading for both. If you have both, you may put your observations ahead of your data table on the page. Note: You should create a sketch of your data table BEFORE you conduct your experiment so you have a place to record your data during the process. Take time to think through what type of data you need to collect. You will need to have column headings (capitalized appropriately) and unit labels for any measurements.

Bold and align according to whatever looks neat, professional, and appropriate.421957553975Science Journal:In addition to your data table, you may also wish to keep a science journal. You are NOT required to keep a journal, however, you may find it helpful when it comes to writing your conclusion, especially if you are recording how something has changed over time; like the example of growing plants with/without worms. A science journal is a record of your observations. You can keep a hand-written journal, or a digital one. A science journal should include:The date the observation was taken and perhaps the timeA sketch of the observation or a digital photo. Label the parts of the sketch/photoNotes about what you are seeing. Color, movement, temperature, size, ments about changes you are noticing from the previous observationSample Science Journal Instructions for Creating a Data Table Using Microsoft Word 2003 and 2007 VersionsTip: It is helpful to sketch the table you want to draw before you create it on the computer. This provides a visual for determining the number of columns and rows you want, and where you may want to split cells.Microsoft Word 2003Place curser on page and click where you want your table to appearClick on “Table” from the menu barPlace your curser over “Insert” and arrow over to “Table”. Click on “Table”Enter the number of columns (up and down) and rows (across) and click “OK”Type your headings and data in the appropriate cellsTo split cells, select the cells you want to split.Click on “Table” from the menu bar and then click on “Spilt Cells”Uncheck the “Merge Cells Before Split” box, choose the number of columns you want and then click “OK”Microsoft Word 2007Place curser on page and click where you want your table to appearClick on the “Insert” TabClick on “Table”. Use the custom grid that show up to select the number of rows and columns. Left click on the grid once you have selected the number of rows and columns. This will automatically send this size table to your pageType your headings and data in appropriate cellsTo split cells, select the cells you want to splitOnce you have created a table, an “upper level” tab will appear above the original row of tabs. Click on the one that says “Layout”Click on “Split Cells”Uncheck the “Merge Cells Before Split” box, choose the number of columns you want and then click “OK”If you are making a Google Site, you may use “Google Documents” to create tables and graphs. Google Docs and Google Spreadsheet work very similar to Microsoft Word and Excel. You may even create your table in Word or Excel and import them into Google Docs/Spreadsheet to make them uploadable to your website. To do this, you need to sign into your Google Site and click on the hyperlink “Documents” in the upper left of the screen. From there you can click “Create New” to make your table or graph right in Google, or “Upload” to transfer a file you made in Word or Excel to Google Docs to format it so it can be imbedded into your website. ResultsThe second (or third) sub-heading of your data-page of your site will be called “Results”. In this section page you will write a paragraph which states your results from your data table. It will be a written representation of your data rather than in just numbers. The sentences in your results paragraph are only statements explaining WHAT your results were. There is NO WHY or explanations given as to why you think you got these results. There is NO relating your results to the hypothesis. For this paragraph, you simply state the facts. You may make some general comparisons in your results, but be careful to not provide any justification for your results or draw any conclusions in this portion of the scientific method. Your results should also follow a logical sequence, beginning with your first data and ending with the last.An Example of Written Results:On the first day, the plants without worms were an average of 0.25 cm shorter than the plants with worms. On the second, third and fourth days, the plants were 0.20 cm different in height, with the plants with worms being taller still. The trend of the plants with worms being taller continued throughout the ten days. On the fifth, sixth, and seventh days, the plants were an average of 0.25 cm apart in height. On the eighth day, the plants with worms were 1 cm taller. On the 9th day, the plants were 0.8 cm different in height. On the tenth day, the plants with worms were 1 cm taller. GraphThe third (or fourth) sub-heading of your data-page the graph of your results. The only data from your data table you willgraph are your averages. The graph organizes a summary of your data in a visual representation that is easier for people to understand than your data table. A graph will also help you in your efforts to analyze your data to formulate a conclusion. 4619625427990As with your data table, your graph must also be computer generated. I recommend using Microsoft Excel for this part or Google Spreadsheet which works like Excel. Be sure to include a main heading/title for your graph, axis headings/titles, units of measurement for each axis, and a key/legend if appropriate. You may choose any style of graph to convey your results (line, bar, pie, etc.) A pie chart needs to be used if you are representing your data in percentages. Feel free to include several types of graphs to give readers multiple avenues of looking at the data. A video tutorial series for how to create a graph in Microsoft Excel 2007 is provided on our science fair website: It is near the bottom of the page. Page 4: ConclusionThe conclusion is the final step of the scientific method (besides sharing your work with others). The conclusion is the part of the project where you make sense of what you learned. Your conclusion should be a MINIMUM of 2 - 4 paragraphs long. The conclusion is where you can explain WHY you think as you do. You will also use data to support your reasoning. The following is a basic outline you could follow when writing your conclusion. These are not broken down by paragraph. You may structure your paragraphs however you think makes the most sense. This is just outlining the logical flow of information you will want to analyze and report. Compare your conclusion to the rubric. Be sure you include all parts from the rubric. The conclusion is the section worth the most points in your project as it is the “meat” of what you have learned. Restate your question. Restate your hypothesis and then why you thought this would be the answer to your question. You may site prior knowledge or other research that lead you to think this way.Next, tell whether you accept or reject your hypothesis. Whether you accept or reject your hypothesis should be based upon your data. You should give examples from your data as you explain why you accept or reject your hypothesis. If you accept your hypothesis, you are saying, based upon your data, your hypothesis is true. If you reject your hypothesis, you are saying, based upon your data, your hypothesis was incorrect. If you reject your hypothesis you should suggest a new hypothesis. Using data to support or reject your hypothesis is the key point here.Discuss the accuracy of your results. Do you think your results are accurate? Why or why not? Was there anything that went wrong in your experimentation, such as something you failed to keep constant, or lack of attentiveness, failure to record data one day, improper technique, etc. that could contribute to your results not being as accurate as they should be? If so, state this and how you think it could have impacted your results. If you think your results are accurate, explain why you believe they are accurate. You can site examples here such as good technique, strict attention to your constants, etc.If you were to ever repeat this experiment, is there anything you would do differently? What and why? Reflect upon any complications you had. Also discuss if this experiment leads you to further questions you would like to investigate.What kind of summary can you draw from your data? In other words, a re-stated answer to your question. How can what you’ve learned be applied to help others in a real-world context? Describe how this new-found knowledge can be used to inform others when making decisions about what products to buy or how it can be used to better our world in some way. This is a critical area of your conclusion. Scientific investigations must help the general public in some way, as ultimately, it is tax dollars that funds research endeavors! Example of Conclusion:Do worms affect height of plant growth? I hypothesized that the presence of worms will make plants grow taller than plants grown in soil without worms. I thought this because I know gardeners add worms to their soil. It would not be logical for gardeners to pay to add worms to their soil if there was no benefit to the plant. I was curious to know if worms aided in the growth of plants. According to my data, I accept my hypothesis. My results consistently showed that the three plants grown in soil with worms added grew taller than the plants grown in soil with no worms added. For example, on the very first day, the average height of the plants grown in soil with worms was 0.25 cm taller than the average height of the plants grown in soil without worms. By the end of my experiment, the tenth day, the plants grown in soil with worms were a full centimeter taller than the plants grown in soil with no worms. I can accept my hypothesis because I believe my results were very accurate. I was careful to ensure all my constants were equal. I measured the amount of soil very carefully for each pot. For the pots with worms, I chose worms that were the same size and heartiness. All pots received the same amount of sunlight, which is a factor in plant growth. I measured four tablespoons of water each day for each plant. I poured the water on the same part of the soil, directly over the sprout. I was very meticulous when measuring the height of each plant, recording the height to the nearest tenth of a centimeter. The only difference among my plants was the presence or absence of worms.If I were to ever repeat my experiment, I would use more plants for each independent variable to increase the accuracy of my results, and see if my hypothesis would prove to be correct in a larger test sample. I may also try this same experiment and substitute the kind of plant to see if worms make plants of a different species grow taller. I may also put a wire mesh over the surface of each pot to ensure no worms escape. This is something I cannot verify for this experiment. I just assume all worms are still in the pot they were placed in.In summary, I can conclude that the presence of worms does affect the height of a plant’s growth. Plants grown with worms grow between 0.20 and 1 cm taller than plants grown in soil without worms. This difference may not be significant enough, however, to warrant the purchase of worms for your garden. A more expensive, and perhaps effective, growth stimulant may be fertilizer.
