How Tall Is That?
This Web site is part of the Top Down remote sensing project funded by NASA. It offers several activities for students in grades 4 through 7. This activity teaches students how to estimate the height of objects by noting the time of day and studying the length and angles of shadows. Clear directions and an outline make this a fun and educational project.

This activity requires some knowledge of ratio and proportion, which may require some assistance for some students.

America's Roof
Do you know which point is the tallest in your state? How about the highest peak in the world? This comprehensive Web site allows you to research mountain heights by state or by country. Also included are coordinates, maps, pictures, and much more. Students can estimate the difference between the high points of two states, and then calculate it using the numbers provided.
