Activity 01
Inquiry Circle: Play-Doh Mountains
In small groups, students build a mountain out of modelling clay. They use a fishing line to slice the mountain horizontally at 1cm intervals. They then trace the outline of each slice onto paper to create their own contour map, seeing firsthand how steep slopes create closely packed lines.
Explain how flat lines represent the height and steepness of a mountain.
Facilitation TipDuring Play-Doh Mountains, ask students to rotate their models slowly while tracing contours to see how the lines change with perspective.
What to look forProvide students with a small section of a topographic map. Ask them to draw a circle around an area with a steep gradient and label it. Then, ask them to identify one landform present in the map section.
