    Homework (3/5 due 3/9) 
    The following videos and resources are related to Thompson's model of the atom 
     
    Webquest “A Look Inside the Atom
     Follow the links throughout this webquest to learn all about Thompson's experiments.  In particular, study the page titled "Three experiments, one big idea".  Answer the following
    q1) Describe Thompson's first experiment.  State his conclusion, and explain how this follows from the experiment.
    q2) Describe Thompson's second experiment.  State his conclusion, and explain how this follows from the experiment.
    q3) Describe Thompson's third experiment.  State his conclusion, and explain how this follows from the experiment.
    q4) Describe the experimental reasoning which established whether the electron is large or small relative to the atom. 
    Next watch the following three video resources and answer the remaining questions. 
    q5) What additional evidence has been presented to show that an electron has mass and other particle-like properties?
    q6) Summarize Thompson's model, and explain how it is a departure from Dalton's earlier model.
