The Round Earth And Christopher Colombus

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...

Starting with the instructions to draw an ellipse, and with great pictures, this sheet should help your pupils learn the shapes and measurements involved. Using push pins and string, your class can discover the axis and focus points...

What locations on Earth get the longest number of hours of daylight in the summer? Hint: It's not the equator! Use real-world sunrise and sunset data to develop trigonometric models that can be used to estimate the number of hours of...

In this math worksheet, learners find all the vectors in three dimensional space that have the length of 4. Also, the first and third components are the same. Finally, the second component is the sum of the first and third components.

In this satellite synchrony worksheet, learners use a spreadsheet or Least Common Multiples to solve 4 problems related to the satellite orbits, orbital periods and their synchronicity. Students determine when the satellites launched in...

More carbon dioxide exists in the atmosphere than ever in human history. An informative video introduces the topic of global warming as part of a larger playlist. It looks at possible causes such as Earth's orbit, Earth's moving axis,...

Introduce your class to the greatest factor on earth. The group of videos introduces factoring polynomials by finding the greatest common factor (GCF). They connect finding the GCF of the terms in a polynomial to finding the...

Build up from the previous activity where your learners charted the population growth and decay of a fish pond with M&Ms®. Have them look at the data from that activity and create a Now-Next, or recursive equations, to predict the...

The ancient Mayans had a complex calendar and number system with a rich history. In fact, the date 12/21/2012 was the center of much controversy as to whether or not it was the end of time. It wasn't the end of time, but...

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