Determining Center of Gravity

Can you use gravity to create a clock? Pupils explore reaction time, acceleration, and gravity in a timely instructional activity. They test how quickly each can catch a dropped ruler, find average reaction times, and calculate percent...

Young scholars explore the concept of flight.  For this flight lesson, students make paper airplanes with different designs.  Young scholars change the angle of launch and thrust and record the distances and time spent in air for each...

In this black hole worksheet, students read about the black hole in the center of the Milky Way Galaxy called Sagittarius A and observe a Chandra image of the area where the black hole exists. Students solve two problems which include...

Students complete calculations involving the structure and properties of matter. They engage in a variety of problem solving activities to help them determine the center of gravity.

The class examines graphs in the form r = F(¿¿) in polar coordinates (r, ¿¿), in particular with the circle, ellipse and other conic sections. They determine the nature of an ellipse by studying the role of the semimajor axis and...

How can you determine the height of a drop off a cliff if you have nothing to measure it with? A movie clip sets up a sky-high challenge and solves it with a falling glow stick. Scholars must take the given information and decide how...

High schoolers explain 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 their planetary systems.

Students differentiate between the weights of an object on different planets. In this geometry lesson, students investigate different weights and graph their results as it relates to the different planets. They appreciate the design of...
