In Spanish. This interactive activity shows how to compute the area of a triangle and the concept of altitude, median and angle bisector. [Requires Java.]

Students are able to manipulate a parallelogram on a coordinate grid to explore properties of a parallelogram and then calculate the distance of the sides, altitude, and area. The resource also includes links to further explain important...

An effective presentation of six main climate controls: latitude, land vs. water, geographic position, altitude, currents, pressure and winds.

[Free Registration/Login may be required to access all resource tools.] Apply the fact that the altitude of a right triangle creates similar triangles.

Learn how to construct the bisectors, median and altitude of a triangle.

This lesson plan presents the idea that the area of any triangle is exactly half of a certain parallelogram -- thus we get the familiar formula of multiplying the base and the altitude and taking half of that. The lesson plan contains...

This site gives an explanation of what the base of a polygon is. The base of a polygon when given the location of the altitude is also discussed.

Investigate the illness known as acute mountain sickness, and describe what happens to the human body when it climbs too high altitudes too rapidly for the body to adjust. Describe ways to avoid altitude sickness.

Explore the injuries mountain climbers can sustain when they reach high altitudes, and discover how extreme cold can damage the human body.

[Free Registration/Login Required] In this flipchart, students use the interactive features of Activstudio to understand how to use the properties of perpendicular bisectors, angle bisectors, medians and altitudes of a triangle.

This site from the Virtual Sun gives a detailed account of the geographical region once inhabited by the Maya People. It describes the landscape, climate, and altitude.

Snow-capped mountains make a picturesque scene, especially in summertime when the peaks are in such contrast to the warmth below. This project shows you a way to see how temperature changes with altitude using data collected twice daily...

An explanation of the different parts of the atmosphere and how pressure and temperature changes at different altitudes.

Celestial navigation is the art and science of finding one's geographic position by means of astronomical observations, particularly by measuring altitudes of celestial objects - sun, moon, planets or stars. This activity starts with a...

Learn all about the different kinds of clouds in our atmosphere, how each forms, and specific details of each. Colored photos and an altitude cloud chart are included. PDF (requires Adobe Reader).

View a global map showing cloud fraction from January 2005 to November 2008. Learn how clouds have a warming and cooling influence depending on altitude.

Here's a fun project that combines baseball and math. Major League baseball is played in ballparks that have their own individual quirks when it comes to the exact layout of the field. Fenway Park in Boston has the famous "Green Monster"...

This interactive feature from the NOVA: "Everest" Web site lets you take the same brain quizzes that researchers have used to test the brain function of climbers on Mount Everest.

Backpacking safety advice is provided. Discusses recommended procedures for particular illnesses and safety tips regarding camp sites,clothing and cooking.

The Centers for Disease Control and Prevention provides information on over 40 diseases that travelers might need to be prepared for. Information includes description of disease, risk for travelers, preventive measures and treatment.

Students understand that the orthocenter is the point of concurrence of the three altitudes of a triangle. They construct circumcircles and Feuerbach circles and determine the relationship between them.

Adjust the altitude and temperature in this simulation to observe how gas pressure is affected by these changes.

Could the altitude of the city hosting the Olympic and Paralympic Games have an effect on performance in the long jump? This challenging activity encourages mathematical reflection, investigation and discussion as students explore how...

This is the second version of a task asking students to find the areas of triangles that have the same base and height. This presentation is more abstract as students are not using physical models. They still determine the area of each...
