Young scholars calibrate an alcohol thermometer using the boiling and freezing point of water. In this physical science instructional activity, students explain what happens to boiling point of water as altitude increases. They calculate...

Students find the altitude of the Sun at 10 A.M., at solar noon, and at 2 P.M. by measuring the height of the gnomon and the length of the shadow at each time. They record the measurements in their notebooks for later conversion.

Students discover how rockets can reach a higher altitude by using staging. They use balloons to demonstrate this concept and then practice with rockets. They discuss the results to end the lesson plan.

Students, in groups, design a procedure to calculate the mass of gas molecules in the classroom by measuring the volume of the classroom and researching the density of air. They apply changes in air density with altitude and effects on a...

Students explain that air pressure applies a force. If any of students have flown in an airplane, they have felt the "popping" of their ears caused by the change in atmospheric pressure because of the altitude changes.

For this geometry worksheet, 10th graders examine the special segments that occur in a triangle.  The three page worksheet contains twenty-five problems.  Answers are not included. 

Students compare rates to altitude. They conduct a class discussion about the results.
