Measuring the Earth

The equator and longitudinal lines make interesting circles to study in terms of arc length. Using Google Earth or a globe, pupils research specific questions about size and distance. This a great activity to bring some real-world...

Students use principles of geometry to measure the circumference of the Earth. In this applied geometry lesson, students use mathematics to determine scientific information. They make measurements, calculate the central angle, and use...

When earth scientists or mini meteorologists are learning about wind, they can participate in an engineering activity in which they will design and construct an anemometer. A thorough overview of different types of anemometers is...

Geometry meets earth science as high schoolers investigate the cause and features of the four seasons. The effects of Earth's axis tilt features prominently, along with both the rotation of the earth about the axis and its orbit about...

How do you fit a tape measure around the Earth? No need if you know a little geometry! Pupils begin by extending their understanding of the Side Splitter Theorem to a transversal cut by parallel lines. Once they identify the proportional...

The slope of the land is an important feature when considering the erosion that will occur. In this resource, which is part of a rain garden unit, learners calculate the slope of the proposed garden site. Even if you are not planning a...

Water, water, everywhere? Each pupil first uses an Internet program to select 50 random points on Earth to determine the proportion of its surface covered with water. The class then combines data to determine a more accurate estimate.

Eleventh graders examine the effect of climate change on Caribou. In this earth science lesson, 11th graders brainstorm ways to adapt to a changing environment. They analyze data of caribou population estimates and calculate statistical...

Students complete mathematical calculations to determine that the sun's diameter is about 100 times that of Earth's diameter. In this sun and Earth lesson plan, students complete worksheets provided.

Students study how to measure and calculate the volume of water flowing down a stream or canal and use simple tools to make measurements. Next, students determine how many people cold live off the volume of water measured. Finally, they...
