How to make an ocean floor model
EXAMPLE 1The Ocean Floor - Plan: Find the definitions for continental slope, trench, basin,. continental shelf, and range. These definitions are the required background knowledge.Materials: Draw a quick plan of an ocean floor as seen from the side; including the edge of a continent, a continentalshoebox with a lid - 1 per group of shelf, a continental slope, a basin, a trench, and a range.2-3 They require their definitions to do this. When the plan is checked and they can properly identifypaper mach, materials (flour, water, each part, the groups set out to create the ocean floor in their shoebox with paper mach.glue mixed in a bowl)strips of newspaper or newsprintpencilscissorsCraft paper
When the paper mach is dry (orclose), the groups cut or punchabout 8 holes spaced evenlyapart down the centre of theshoebox lid. The lid is then put onthe box, hiding the ocean floor. Once the graph is set up properly,The students take their graph the students put the dowel inpaper and create a graph with the hole #1 until it hits "bottom".numbers one to eight along the They record the measurement onbottom (number of holes) and the graph with a simple dot. Thisabout 1-25 (measurement in cm) continues for holes #2-8.up the other side. When all of the holes have been measured, the students should join their dots using a ruler in order. When this is done, they should turn their graph upside down and label the parts of the ocean floor appropriately. They should see a representation of the floor they created in the shoebox.
EVALUATIONEvaluation:Which feature forms most of the ocean floor?Where would you find the best fishing zone according to the features of the ocean makeup?Where is new ocean floor created? How old is the ocean floor? Explain.
