Reviewed by: Christine Hirst, West Ranch High School


Location: Natural History Museum
For directions and parking information click here.

Description:  Students will be visiting the Natural History Museum, Gem and Mineral Hall. This has many fantastic exhibits and halls, including the brand new dinosaur exhibit.There is also the opportunity to see real scientists in action at the dino lab.  

Cost: FREE Tuesdays!!! $9 with student ID, $12 for non-students 



Audience
  • A fledgling earth science teacher would benefit if they lacked content knowledge.  Many are forced into teaching this awesome subject and rely on worksheets and didactic book work, failing to see the tangibility of this science. 
  • An earth science student would benefit from seeing the many wonders the earth can create and the practical nature of earth science 
  • An earth science student would benefit from seeing the many local examples of earth history and geology, as well as the discoveries of gems, resources, and meteorites
  • students and teachers alike will benefit from seeing the importance of local and regional geologic processes and the influence over the local landscape

Science Concepts Addressed
  • Physical environments influencing the creation of rocks and minerals
  • physical characteristics and properties of minerals
  • comparative visual properties of minerals
  • properties of gems of economic interest
  • geographic relationships to geologic formations

  • Role of California in formation of minerals
  • formation and discovery of meteorites
Study Guide:  Develop a study guide that could be used by students visiting this site. The study guide should be very clear and address specific science concepts.  The study guide should include the following:
Informational map: A simple map of the field trip site with key features labeled.
  • Tasks:  At least three tasks for the students to perform while at the field trip site. 
  • Observations:  A minimum of 10 observational (factula) questions that could only be answered hat can only be answered if the students has visited the site. 
  • Higher Order Questions / Activities:  A minimum of 3 higher order questions or activities that can only be answered if the students has visited the site. 
  • Photos:  Photos that will help orient the visitor to the site. Post photos on the photo album and use their urls to insert them here. 
  • Post the study guide as a pdf attachment to this website. Copy the text and include it in the study guide section.
