Information
Description
What It Is:
This is an Earth Science worksheet focused on seafloor spreading. It includes background information about the process of seafloor spreading, including the formation of new seafloor at mid-ocean ridges and the subduction of older seafloor at trenches. The worksheet also includes a hands-on activity to construct a paper model illustrating how seafloor spreads. The activity requires cutting, coloring, taping, and threading paper strips. It provides a vocabulary section defining 'magma' and 'seafloor spreading.'
Grade Level Suitability:
This worksheet is suitable for grades 6-9. The background information is presented in a way that's accessible to middle school students, and the paper model activity provides a visual and tactile learning experience. The vocabulary is appropriate for this age group as well.
Why Use It:
This worksheet helps students understand the concept of seafloor spreading, a key component of plate tectonics. The paper model provides a visual aid that enhances comprehension of how new seafloor is created and older seafloor is recycled. The activity promotes hands-on learning and reinforces the concepts presented in the background information.
How to Use It:
First, students should read the background information to understand the process of seafloor spreading. Then, they should follow the step-by-step procedure to construct the paper model. This involves cutting out the model, coloring the strips, taping them together, and threading them through the slits. Finally, they can manipulate the model to simulate seafloor spreading and observe how new seafloor emerges at the ridge and disappears at the trenches.
Target Users:
This worksheet is ideal for middle school science students learning about plate tectonics and Earth's structure. It can also be used as a supplementary activity for high school students reviewing these concepts. Teachers can use this worksheet as part of a lesson on seafloor spreading or as a hands-on activity to reinforce learning.
