Molecular Geometry

Introduction
  • The learning target of this lesson is to learn how molecular geometry relates to points, lines and planes using the link under the process tab.
Task
  • Students will get in groups (3 - 4 students) and use the link under the process tab to find information about molecular geometry
  • Each student should have a part- a reader (should have an iPad), note taker (writes notes), and a decision maker (decides on what molecule to choose as well as making sure answers are correct.)
Process
  • First, click on the following link https://www.ck12.org/book/CK-12-Chemistry-Intermediate/section/9.2/
  • Reader will read the paragraph about molecular geometry (in bold).  Note taker will take notes on this.
  • Then answer the following questions: What is molecular geometry? What important factor affects the physical and chemical properties of a compound?
  • The decision maker should then decide on a linear and planar molecule using the same link, then write what molecules were chosen.
  • Answer the following questions:
  • Why is the molecule linear/ planar?
  • How did the molecules your group chose inherit their names?
  • Sketch the shape of the planar molecule your group chose. Answer "What shape represents this molecule's structure?"
  • Next, there will be materials provided for your group to build the planar molecule chosen.
  • Grab enough tooth picks and packing peanuts for the structure of the molecule, then start building!
Evaluation
  • Teacher will evaluate students by circulating around classroom and making sure every group is staying on task.  
  • Students will also submit the WebQuest assignment before class ends, which be evaluated for a grade.
Conclusion
  • Students should have learned the basics of molecular geometry and how it relates to points, lines and planes.
