In this activity students will apply the concept of triangulation in a variety of problem solving situations involving the Aurora Borealis. They learn that before the advent of photography in the 1880's, auroral observers tried to determine the height of aurora by the method of triangulation and, from the geometry of the triangle, they estimated that aurora occurred between 650 to 1,000 km above the ...

This article discusses the results of a mathematical study on how efficiently the energy of the sun is converted into fossil fuels. It points out that plants convert the sun's energy in to carbon, which is the basic constituent of natural gas, oil, and coal. However, the process is inefficient in that only about 9 percent of the carbon in the original plants is converted into the form of coal, and ... Full description.

In this activity, students mount a covered mirror on a wall at eye level, then work in pairs to predict where two people must stand so each can see the other's reflection in the mirror. Each pair will discuss and agree on the places where they think they must stand, then remove the cover from the mirror and test their predictions. As an extension of this activity, they can design and construct large ... Full description.

In this activity, students fasten two mirrors together using masking tape and observe the relationship between the angles of the two hinged mirrors and the number of images produced. Students mark angles between 180 degrees and 20 degrees. They open the hinged mirrors to each of the specified angles, place an object between the two mirrors, and count and record the number of images they see. In a ... Full description.

In this activity, students use a variation of the method of measuring the diameter of the Sun that utilizes the same principle involved in making a pinhole camera. They substitute a masked mirror for the pinhole and a darkened room for the box. The advantage of this technique is that the Sun's image is cast over a greater distance, thus enlarging the image. Because the experiment is done in a darkened ... Full description.

In this activity, students will construct a device to measure slope (clinometer), use it to measure a series of slopes in their area, and relate the concept to physical structures around them. Clinometers will be constructed using the material and instructions provided with the activity. Working in groups, the students will measure three slopes they select themselves and calculate the result in both ... Full description.

In this exercise, students investigate the use of conditional probability (the likelihood that a given event will occur within a specified time period) in assessing earthquake hazards. Introductory materials explain that conditional probability is based on the past history of earthquakes in a region and on how and when earthquakes recur; and discuss the different types of models that can be developed ...
