03.08_Topographic Maps Project Day 8
3
Learning Objective: YWBAT convert your 2D traces into 3D objects.
Essential Question: What strategies can we use to ensure our models will be fit to print?
Take out your notebooks!
Unit 3 - Creating 3D from 2D
Do Now: 1. Draw arrows pointing to the index contours on the map.
2. Find the contour interval of the map – show all work.
3. What is the steepest part of the island? How do you know?
4. Where are the peaks of the island? How can you tell?
Keep in mind:
1. What is the steepest side of the hill?
How do you know?
2. What is the least steep side of the hill?
How do you know?

Vocabulary
3. Which point is the highest elevation? Put an X
4. Where is the river? Circle it
5. Which way is the river flowing?
6. Contour interval:
7. Elevations A: ______ B: _____ C: _____
Topographic map: shows changes in elevation of Earth's surface
Contour line: connects points of equal elevation
contour interval: The difference in elevation between 2 side by side contour lines

03.07_Daily Assignment:
- Turn your 2D traces into a 3D map in Tinkercad
03.08_Add text to your 3D model
- Add 1 to 2 index contours, the name of your map, and the contour interval.
- Confirm that your 3D topo map is ready to print (checklist within 03.08).
No music until you complete Parts 2 & 3.
Rules
1. The closer together the lines
are, the more steep the hill is.
2. Smaller circles represent higher elevations
3. Contour lines bend upstream
when they cross a river
