Activity: Graphing the Sea Floor

Thursday, March 12, 2015

Activity #3 Graphing the Sea Floor
Time: Approximate time to complete this activity: 1 day (class period)
Materials:
  • Computers and internet
  • Graph paper with some points filled in
  • Data sheet
Guiding Questions
  • How do scientists know about the topography (vocabulary word) of the ocean floor?
  • How does sonar work?
  • What physical features do you think youwill recognize that you learned about when studying plate boundaries and volcanoes?
Plan
  • Plans for part 1 of activity:
  • Students will write a reflection in their notebooks on their results.
  • Guiding Questions to ask during this part of the activity:
  • How do scientists know about the topography (vocabulary word) of the ocean floor?
  • How did the sonar work?
  • Anticipated Student Responses to guiding questions:
  • Scientists use sonar to help them know the topography of the ocean floor.
  • Sonar is a sound that reflects off of the ocean floor.
  • Plans for part 2 of activity:
  • Guiding Questions to ask during this part of the activity:
  • What characterisitcs do you see upon graphing the ocean floor?
  • Do you recognize any physical features that you learned about when studying plate boundaries and volcanoes?
  • Anticipated Student Responses to guiding questions:
  • Discourse – Guide discussion toward the use of sonar and ocean floor features.
Differentiation:
  • Strategy 1: For the graphing of an accurate model of the ocean floor, have part of the graph filled in.
ELL Modification:
  • Modification: Pair student with another student with whom he/she can work well.
Check for Understanding: Check in with students throughout this activity for comfort with the Gizmos activity and graphing the ocean floor. Assist as needed. Collect graph to assess understanding.
