 Title- a short description of the lab, state dependent and independent variables!

Exp:  The Effect of ________ on _________

 

PRELAB (Purpose, Hypothesis and Procedure) May be written in journal or typed, but final report ALL parts must be typed)

 

Abstract: A shortened version of your entire paper. Others can read your abstract if they do not have time to read your paper. It is written AFTER the other parts of the report are written.  The Lab abstract should be no more than 200-250 words.

Rules for writing abstracts:

1) Avoid use of pronouns (I, we, our, my…)

2) Write in past tense 3rd person style

3) Single space, 10 font, indented (the rest of the lab should be 12pt font!)

4) Don't be vague, identify each part of the abstract for what it is (the purpose was, the hypothesis was, the null hypothesis was, etc)

Guide for writing an abstract:

        * THE FIRST sentence should restate the purpose of the experiment

        * THE SECOND sentence should restate the hypothesis

        * THE THIRD sentence should restate the null hypothesis

        * THE FOURTH-FIFTH sentences summarize the procedure including how the control was established (this is NOT a list…use sentences)

        * THE SIXTH-EIGHTH sentences summarize the data (this is NOT data tables…use sentences to explain the findings), including the

                     statistical analysis if applicable.

        * THE NINTH-TENTH sentences summarize the conclusion being sure to mention whether the results supports the hypothesis or null

                        hypothesis and reference the statistics here that support your conclusion.  Include possible errors, and an error analysis if

                         applicable

Purpose: What is the point of the lab, what are you trying to learn, why it is interesting, etc. Approx. 2 sentences to 1 paragraph (NOTE: This will be easier to do after you have read the lab, don't just guess!)

 

Hypothesis: An if, then, (because) statement. The lab may say in it what it is trying to prove, if so, summarize in your own words. If not, what do you think the results of the lab will be? 1-2 sentences to 1 paragraph. (NOTE: Again, this will be easier to do after you have read the lab!)

 

Null Hypothesis: An if, then, (because) statement that reflects the idea that there will be NO change or NO effect of the independent variable on the experiment, it is NOT necessarily the opposite of the hypothesis (the opposite effect of the independent variable).

  

Procedure: Summarize all the steps of the lab. Be detailed, but don’t exactly copy the lab manual. One should be able to repeat the lab based on you notes in this section. Number your steps (no bullet points, no paragraphs)

              

             Include any pictures, measurements, tables, etc. made/used during the lab in this section

              

            This section is to be as long as is necessary to include all information.

 

 Observations: Answer all observation questions, include any graphs necessary. Number answers (rather than putting them in paragraph form).

 

            Next, use your senses! What could one see, hear, smell (if appropriate), taste (if appropriate), and touch (if appropriate) during this lab. Include these observations, you never know what will be important when you start to draw conclusions! You should have at least 3-4 sentences of your own observations (in addition to your answers to the observation questions).

 

            This section should also be as long as is necessary to include all information. It should be at least 1-2 paragraphs.

           

            If references are used, be sure to include the number of the reference according to your reference page, in parentheses, after the sentence(s) containing the information.

 

Conclusion: Answer all conclusion questions. Number answers (rather than putting them in paragraph form).

 

            Next, draw your own conclusions! Also known as a “power conclusion”, your conclusion is your summary of the experiment, the data you collected, experimental error, and future implications for experimentation. Use the power conclusion writing help to make sure you have included all aspects of a good conclusion. You should have at least 4-5 sentences of your own conclusions (in addition to your answers to the conclusion questions).

 

            This section should also be as long as is necessary to include all information. It should be at least 1-2 paragraphs.

 

            If references are used, be sure to include the number of the reference according to your reference page, in parentheses, after the sentence(s) containing the information.

 

References: Cite references, including the lab/information used to create your procedure and your text book (lecture), used to find information or definitions to help answer questions or make statements in the observation and conclusion portions of the lab. They may be referenced using the APA or MLA format (APA is typically used in science disciplines). For help creating APA and MLA references go to the Citation Machine Website, on the left hand side of the screen select APA or MLA, then the appropriate reference type. ALSO, use in-text citations (parenthetical citations) to indicate what information came from which reference! Simply numbering your references and putting the number in parentheses after the statement(s) using the reference is sufficient (proper APA in-text citations use the authors name and the year the material was published).

(PRELAB) Purpose, Hypothesis and Procedure will be done in lab book only. You may type if you prefer.

 

NO ABSTRACT NEEDED!

 

Questions will be answered in a worksheet format either on an actual worksheet or in your journal. No additional observation or conclusion information is necessary. References must be included if needed (it almost always will be needed!).
