Learning Intentions

• You can reflect on your success in the last unit and make a plan for success in our next unit.  

• You can determine which texts are most reliable from a list of research resources.

•  You can create a matchmaker profile on a scientist from history using provided resources that explains some information of personal background, major experiments they used to learn about atoms and what was their scientific contribution to the current atomic theory.

•  You can use a provided rubric to assess and modify your own work if necessary before presenting.
