Great Circle Teacher Resources

Guide your class in this computer-based activity to explore Earth's spherical geometry and the concept of the Great Circle. Map projections and relative distances between places on Earth's surface are used to facilitate spatial and...

Students compare routes between Minnesota and China using a map and globe. Using the "great circle route" method, students find the shortest route between two points.

The teacher diagrams and explains the different terms of what comprises a sphere. Follow along and learn about the: radius, diameter, great circle, center, and hemisphere.

Here is another learning game that will engage your kindergartners and support them with their counting fluency. Forming a circle where everyone faces inward, choose a counting sequence (counting frontward or backward) with no more than...

Young scholars differentiate between different planes. In this geometry instructional activity, students differentiate between a plane and a sphere. They discuss the Great Circle, Geodesic and Lune as it relates to the earth.

Maybe the world wasn't built in a day but kids can certainly assemble a globe in one class period using the images provided by these templates. Cut, fold, piece, glue, and voila!

From the light reaction to the Calvin cycle, this presentation contains information about the various stages of photosynthesis.  This is a great supplement to some of the biochemistry-heavy presentations about the specific mechanisms....

Learners explore two and three-dimensional objects with a hands-on approach and an element of chance. Groups choose the name of a solid figure from a "hat" and work with that shape. They sketch it, determine the number and shapes of...

Young scholars investigate properties of circles. In this geometry lesson, students differentiate between similarity and congruence as they observe polygons. They investigate properties of two and three dimensional shape.

Establishing clear expectations is a good way to help kids know what they should be focusing on in class. Here is a study guide, perfect for handing out at the start of a unit on geography. They'll use each of the 18 topics and...

Right triangles from 2,000 years ago? Learners investigate different right triangles found in the earthworks of the Hopewell people, a Native American culture that populated the United States from 200BC to AD 500. Learners apply concepts...

A fabulous presentation/activity based on geography. The author has designed a "baseball game" where batters advance to the next base if they correctly answer a multiple choice question about geography. Geographic terms are used, along...

Eighth graders discover the fundamental advantages/disadvantages of both maps and globes. They see that maps may distort size, shape, distance and direction. They discuss the advantages and applications of 5 types of map projections and...

Students develop their globe and map skills, In this geography lesson, students examine the Vietnam War as they complete an activity that requires them to plot latitude and longitude.

In this geometry worksheet, students define important vocabulary dealing with circles. They measure cricles to the nearest degree. There are 11 word problems to be solved.

Students determine the causes of changes in season. For this earth science lesson, students relate the Earth's tilt to seasonal changes. They list traditional activities that take place in various seasons.

Pupils identify and locate cattle trails on a globe. In this map skill lesson, students use a marker to locate Texas and Montana and use the map scale to calculate the distance of the cattle trail.

Sixth graders write research reports about trains. They focus on mechanical features of trains.

In this world globe worksheet, students read a detailed one page text about how to measure distance on a globe. Students answer 5 questions that will require a globe.

It is so important for impending high school graduates to start thinking about their potential careers. Here, they discuss the persistence of Blondie Hasler and his impressive transatlantic trip. They follow various routes on a map and...

First graders sing and dance the Hokey Pokey bilingually. They read and sing the Spanish words for prepositions and act them out as they sing and act out the motions to the song, "El Joki Poki" (The Hokey Pokey).

Students calculate the distance on a sphere. In this geometry lesson, students compare and contrast between plane geometry and spherical geometry and how you would calculate the distance for each.

Students examine the relative size of circular objects from the microscopic to the size of the sun. They calculate the center of a circle given the chords of an arc, watch a video, explore various websites, and calculate the...
