TASK 6 Comparative Experiment – Design/plan your investigation

Step 1: Variables (Independent, dependent, Control Group)

On the googleslide, that you have previously created, add a new slide and title it "Variables" (see template from TASK 2, Step 4).

    Include each of the following in your googleslide:

    a. Independent Variable (something that you will change or manipulate). Each project must have at least 2 independent variables. list the general variables you are changing, not the specific         substances/conditions you will test (Ex: "types of liquid", not "sprite, orange juice, and water").

    b. Dependent Variable (something(s) that will change in responds to independent variable). Things you are observing or measuring in your experiment in order to collect data and to answer research question.

    c. Control Group (something that will not receive any experimental treatments, and will be used as a baseline to compare results).

    d. Constants (factors that will stay the same throughout your experiment). Give at least 2 constants; most experiments will have more. DO NOT include methods of measuring/calculating as constants.

Step 2: Material List

On the googleslide, that you have previously created, add a new slide and title it "Material List" (see template from TASK 2, Step 4). Use two column layout for this slide. You can change the layout by selecting "slide" from top menu bar > select "apply layout" > select "title and two column".

  Part 1: Create material List

  • List all of the materials used for this project

  • Use bullet points for each item

  • Be sure to include accurate measurements, sizes, and quantities of the materials used

  • Be sure to include units when appropriate ( e.g., 5 ml, 10 g, 10 minutes)

  • Be sure to use correct scientific term and size for any science equipment or tools you use

    • e.g., Correct: One 500 ml Beaker, Incorrect = One large cup

    • e.g., Correct: 50 ml of deionized water, Incorrect = water

    • e.g., Correct: Electronic balance with .1 gram accuracy, Incorrect = measuring scale

Part 2: Pictures of your Materials (Optional)
     You may chose to include picture of materials by adding another slide to your googleslide presentation.  On this page, see Step 3 Procedure-Part 2 Tips, for how to insert and label pictures.  

Step 3: Procedure

On the googleslide, that you have previously created, add a new slide and title it "Procedure" (see template from TASK 2, Step 4).

Part 1: List all the procedures

  • Type each step as a numbered list (e.g., 1, 2, 3)

  • Write in 2nd person present tense (like you are telling someone what to do)

    • Correct: 1. Measure 200 mL of water and pour into bowl

    • Incorrect: 1. I measured 200 mL and poured it into the bowl

  • Include diagrams, if necessary, to explain the setup

  • Be detailed – one of your classmates should be able to read your procedure and do your experiment!

  • If you repeat the same steps but just use a different chemical/liquid/size of object, etc., it is fine to say “Repeat steps x to xx using [new material] instead of [original material]

  • Steps should be no more than a few lines long – if they are longer, break them up into simpler steps

DO NOT copy and paste steps from any source – if you got ideas for your procedure from another source, you should rewrite them in your own words. (The source should be listed in the bibliography.)

Part 2: Pictures of Experiment and Result

Include pictures for all major steps and results (this step can be completed later on, as you carry out the experiment).
  • Take pictures of your experiment (make sure your face is not showing on the picture). For some experiments, it might be better to also record the change using a video camera. You may use your own judgement or consult with your teacher to see if video recording is necessary for your experiment.

  • Include pictures of all major steps (Note: do not include your or other student's face on any of the pictures).

  • Show before and after change for results/observation when applicable.

  • Be sure to include more slide(s), when needed.
Tips for saving and inserting pictures to googleslide presentation:
  • It is highly recommended that you save all of your pictures related to the project on the google drive under school email.  Also, save these pictures on a USB drive as a backup.

  • To insert pictures, go to “insert” from the top menu bar.

  • Select insert “image”

  • Depending on where you have saved image earlier, you can select appropriate option “upload”, “take a snapshot, “google drive” and/or “your album”.  

  • After adding the image(s) you can resize it, by highlighting and dragging the corner of the image. You can also change the position of the picture by dragging and dropping it to another location on the slide.

  • Label and/or describe the picture by using textbox from the toolbar.  

Step 4: Safety and Regulation (if any)

On the googleslide, that you have previously created, add a new slide and title it "Safety" (see template from TASK 2, Step 4).
  • Be sure to include all safety precautions that you will use to protect yourself. e.g., wear goggles, gloves, lab coats, adult supervision.
  • If you are working with chemicals (house hold or laboratory grade) be sure to list safety guide lines from the Safety Data Sheet information.
  • Be sure to include proper disposal methods for chemicals and biohazardous materials.
