                         Reaction Rate Project

 Reaction Rate: How does temperature affect the rate of a chemical reaction?

 Design and conduct an experiment to test how the temperature of water affects
 the rate at which Alka-Seltzer tablets react. Gather data using multiple
 temperatures of water to determine the fastest and slowest reaction rates.


Step 1: Observe/question
    Question: How does temperature affect the rate of a chemical reaction?
    Research: A minimum of 1 page typed in an outline format. You must
      include at least 5 resources in the proper bibliography format (2 of the 5
      sources must be a book/encyclopedia/scientific magazine).
    Research topics:
                 What is the difference between an element, compound, and
                    mixture (solution)?
                 What is a chemical reaction? What are the parts of a chemical
                    reaction?
                 Why do things react with each other?
                 What factors affect the speed of a reaction and how do they
                    affect it? ( specifically temperature)
                 What is the chemical make up of water and Alka-Seltzer? What
                    are some chemical and physical properties of each?
                 What is the result of the water and Alka-Seltzer reaction?



Step 2: Hypothesis
    Write a hypothesis (educated guess) that answers your project question using
      your research in step 1. In other words, what is the answer to your question?
    What part of your research led you to this hypothesis? (Make sure to explain
      WHY you chose this as your hypothesis.)
Step 3: Experiment
    TAKE PICTURES OR VIDEO DURING YOUR EXPERIMENT
      PROCESS. THIS IS A REQUIRED PORTION OF YOUR WRITE-UP!
      THE PICTURES/VIDEO WILL ALSO BE GREAT FOR YOUR
      PRESENTATION!
    List all the materials needed to complete your experiment.
    Record the step-by-step procedure that you followed in order to test your
      hypothesis. This needs to be SO detailed that another scientist could repeat
      your steps and get the same results as you did. Read over your procedure to
      make sure it makes sense!
    Make sure that all the other variables stay the same (i.e. amount of water, ,
      amount/size of Alka-Seltzer, etc.)
    DON’T FORGET TO RECORD YOUR DATA THROUGHOUT THE
      ENTIRE PROCESS!!!
         o Quantitative data chart includes:
                 Temperature of water – don’t forget units!
                 Time of reaction (Trial 1 Trial 2, Trial 3) – don’t forget units!
                 Average time of reaction – don’t forget units!
         o Qualitative data chart includes:
                 Temperature of water
                 Trial number
                 Observations during reactions (what do you see!?)


Step 4: Evaluate
    Type a couple paragraphs that answer the questions below by evaluating
      your hypothesis and experiment. Don’t forget to include specific details
      from your experiment data when writing your evaluation.
         o Does your data support your hypothesis? Why/why not? Use data
            from your experiment. What did you find out/learn from this
            experiment?
         o If it didn’t support your hypothesis, what is your new hypothesis?
            What evidence supports this new hypothesis?
         o Which variables couldn’t you control? How could that have affected
            your experiment results?
         o What did you find out/learn from this experiment?
         o What would you do differently/change if you would do this all over
            again? (Note: Do not simply say that you would change your
            hypothesis to be correct. Instead, think about the process. What
            could you do differently to make it more effective? What could you
            do to improve this project if you did it again?)
    Include a RANKING that lists the fastest reaction temperature to the
      slowest reaction temperature.
Step 5: Communicate
    Remember, this is a BRIEF summary of your project (2-3 minutes)!
    Your presentation should follow the scientific method. Explain what you
      have done for each step of the scientific method.
    What is the answer to your question in step 1? What science supports this
      answer? Summarize your findings.
    What did you learn? Please include specific details about your new
      knowledge.
    How are you assessed? See the rubric below when planning your
      presentation:
