Warm up

• What makes a good science project?

• good explanation, testable hypothesis, answer

• Good topic

• Model/ good visual display

• Evidence, science log, Conclusion

• Correct info/examples

• Good experimental design controls/variable

What is a map?

• A model representing a place

• Globe is the most accurate model/map

• Other maps are easier to carry and may have the details you want

What makes a good/useful map?

• Scale• Clarity• Legend• Index• Inset map• Accurate information• Color• Fits your purpose• Compass rose

Warm up

• (Table)• What do the latitude and longitude of Boston,

Anaheim and St. Petersburg tell us?• Region of country, neighbors, plate• Hemisphere• Coast - longitude• Climate – latitude• Time zone

• Boston – 42o N, 71oW

• Anaheim – 33oN, 117oW

• St. P – 27oN, 82oW

Latitude, longitude

Tells distance from equator, distance from Prime Meridian

Warm up

• Draw a scale model of your table

Scale

• Measure then shrink or grow

• Map scale the ratio between the model and actual

• 1:25000

• 1cm to 25 000 cm – Boston topographic map’s scale or 1 cm to 250 m (0.25km)

• Sketch a map of the stairs

• Mercator – cylindrical, distorts near poles, good for navigation, line of latitude and longitude are perpendicular

• Planar – gnomic, polar projection, good at a pole, distorts equator, etc

• Conic – polyconic, good for smaller areas, US map
