This introduction to coordinates on a sphere explains how latitude and longitude define locations on Earth, and similarly, how declination and right ascension define locations on the celestial sphere. The lesson also introduces systems of time-keeping, e.g. local solar time, time zones, universal time and the International Date Line. The objectives are for the student to know how any location on Earth ... Full description.

This lesson covers basic methods for finding one's position on Earth. Latitude can be deduced from the height above the horizon of the pole star or of the noontime Sun, while longitude requires an accurate clock giving universal time. The student will understand how finding one's local longitude requires comparing local time with universal time (UT), which may be obtained from an accurate clock, possibly ... Full description.

This introduction to the labeling of points on a plane by their Cartesian coordinates can optionally be extended to coordinates in 3-dimensional space, to plane polar coordinates and to 3-dimensional polar coordinates. Students should learn to use Cartesian coordinates (x,y) for defining the position of a point in two dimensions and to use Cartesian coordinates (x,y,z) in 3-dimensional space and learn ...

This lesson provides an overview of solar and lunar calendars, their history and lore and also, of the day and the month, and their relations to the rotation period of the Earth and the orbital period of the Moon. Students learn the differences between a solar day, sidereal day and mean solar day, and what each is used for as well as the differences between the solar year and the Julian and Gregorian ...

This lesson includes a historical review, starting with the existence of the horizon at sea, proceeding to various studies of the Earth's size and shape, and leading to the attempt by Columbus to reach India by sailing westward. Students will understand the concept of the horizon at sea as evidence that the Earth is round, calculate the size of the Earth using Eratosthenes' methods, and the origin ... Full description.

This lesson introduces "pre-trigonometry," the estimate of the distance to a far-away point. Students will use "pre-trigonometry" to calcuate distance and will use the "thumb method" of estimating distances in the field and understand the reason it works. Finally, they will understand how astronomers used the diameter of the Earth's orbit around the Sun as a baseline for estimating the distance of ... Full description.

This lesson describes the calculation by which Aristarchus used the duration of a total lunar eclipse to deduce the distance of the Moon. Students will learn about eclipses of the Moon and a simple application of pre-trigonometry as they discover how Aristarchus, a Greek astronomer of 230 BC, used a simple observation of the eclipse of the Moon, plus clever reasoning, to deduce the distance of the ...

This lesson traces the beginning of the heliocentric theory of the solar system, the idea that the solar system revolves around the Sun, to an observation by Greek astronomer Aristarchus, which convinced him that the Sun was much bigger than the Earth. Students will learn how Aristarchus used the position of the half-full Moon to estimate the distance to the Sun, and the results he obtained by employing ... Full description.

Comment on this resource
In this lesson the ellipse is studied in polar coordinates (r,f), with the function cos(f). This places the origin point at a focus (more appropriate for planetary motion) and introduces the eccentricity e. It is also noted that planets actually orbit the center of gravity of the solar system and that distant planets may be detected by motions of their central star around the centers of gravity of ...

This activity has students use simple sine waves to explore constructive and destructive interference in seismic waves. After plotting the summative points of two sine waves, students connect the points to create the resulting complex wave. Once they have successfully drawn their complex wave, they will answer the questions listed on the student handout. Provided are: a list of materials, procedure, ... Full description.
