Description
What It Is:
This is a science worksheet titled 'Sea-Floor Spreading Lab.' It includes an introduction explaining the discovery of magnetic anomalies and how they relate to sea-floor spreading. There's a diagram illustrating magnetic polarity reversals and their symmetrical pattern on either side of a mid-ocean ridge. The worksheet also outlines a procedure for creating a model of the Mid-Atlantic Ridge to demonstrate plate motion and seafloor age.
Grade Level Suitability:
This worksheet is suitable for middle school (grades 6-8) and high school (grades 9-12) Earth Science classes. The concepts of magnetic reversals, plate tectonics, and sea-floor spreading require a certain level of scientific understanding that is typically developed in these grades.
Why Use It:
This worksheet helps students understand the concept of sea-floor spreading and its supporting evidence, including magnetic anomalies. It promotes critical thinking by requiring students to analyze diagrams and understand the relationship between magnetic polarity and the age of the sea floor. The model-building activity enhances kinesthetic learning and reinforces the understanding of plate tectonics.
How to Use It:
Begin by reading the introduction to understand the background of sea-floor spreading. Analyze the diagram showing magnetic polarity reversals and their relationship to the mid-ocean ridge. Follow the procedure to create a model of the Mid-Atlantic Ridge, observing how the age of the sea floor increases with distance from the ridge. Use the information and model to answer questions and solve problems related to sea-floor spreading.
Target Users:
This worksheet is designed for Earth Science students in middle and high school, as well as teachers who are looking for a hands-on activity to teach the concept of sea-floor spreading and plate tectonics.
