Determine the rate of coastal erosion by estimating changes in historical aerial photos.
Use an aerial photograph to determine the distance around a track and then calculate rate and time for each lap and the race as a whole.
While population growth is often associated with exponential functions this activity explores a linear model for one Michigan county.
Investigate rates of population growth and decline with US Census data.
Site a water tower shared by two towns at the midpoint and determine the costs involved using the Pythagorean theorem.
Points on the surface of the earth can be plotted using a coordinate system made from lines of longitude and latitude.
Explore flat geometry (Euclidean) that is based on figures on a plane versus spherical geometry (non-Euclidean) that is based on figures on a curved surface.
Use an aerial photograph to determine the perimeter and area of the mall; consider other shape permutations.
Use remotely sensed data to estimate and measure the area of (center-pivot irrigated) crop circles.
In this video segment from Cyberchase, the CyberSquad replaces a piece of track to get the Madre Bonita Express to the Mother's Day harvest.
Find the area of a complex figure by dividing it into simpler shapes such as rectangles squares triangles and trapezoids.
By creating similar triangles it is possible to find the distance across a river using indirect measurements.
Starting with the location of all Life Flight hospitals in a state use perpendicular bisectors to draw boundaries between Life Flight regions which will inform first responders.
Find the circumcenter of a triangle which is the point where the perpendicular bisectors of the sides of a triangle intersect and is equidistant to each vertex.
Use an aerial photograph to determine the volume of the Great Pyramid of Giza.
Students will examine and interpret a population chart published in 1898 — depicting changes in the makeup of the United States across time in three categories, “foreign stock,” “native stock,” and “colored” — as well as an 1893 political cartoon about immigration. Students will also explain the causes and effects of population change in the late 19th century.
Students will use the Census Business Builder: Small Business Edition data access tool to gather and analyze information that entrepreneurs may consider when opening a business. This introductory activity assumes that students have limited experience using data access tools.
This notebook is intended to give a brief introduction to elementary functions emphasizing on effective thinking in algebra and geometry.
Students will look at data showing how the “millennial” generation differs from other generations. They will analyze and evaluate social changes evident in the data. Then they will work with a partner to compose a newsletter.
Students will explore maps containing census data from 1950 through 2000. They will analyze how education levels and median household incomes have changed over time and determine how the two might be correlated. Students will also come up with ideas for policies that could help address issues related to income and education.
