Earth Science Unit StudyWeek 8: We created our own contour maps.
Contour maps are valuable navigating tools for hikers and naturalists. The wavy lines indicate elevation and are always closed loops. The video How to Read a Map & Contour Lines explains several unique features of contour maps. For example, when the wavy lines point towards a peak, that is an indication there is a low path such as a stream bed running down the mountain.
Janice VanCleave's A+ Projects in Earth Science: Winning Experiments for Science Fairs and Extra Credit in which we created contour maps using clay, toothpicks, rulers and embroidery floss (or dental floss).
First an irregular shaped mountain was created.
This visual, hands-on activity created a much deeper understanding of reading contour maps.
