Drag Problem Set

If Earth is modeled by a grapefruit, what planet could be represented by a golf ball? This activity uses everyday and not-so-everyday objects to create a model of the Solar System.

Young scientists learn how to select a scale factor for a large scale model. Then they figure the scale for each of the planets and the distance between them. Finally, they construct a giant scale model of the solar system and answer...

Between the time scientists discovered Pluto and reclassified it as a dwarf planet, it did not even make one full revolution around the sun. In two activities, scholars investigate scale models and their properties. Pupils find that it...

What does the past have to do with today? Young scientists find that answer as they learn more about past chemists and their significant contributions to the field. Pupils use the Internet to research historical figures...

Students model quadratic and linear equations. In this algebra lesson, students solve word problems using equations. They create scatter plots and make predictions using correlations.

Using a teacher-built wind tunnel constructed from a paper concrete tube form, a fan, and a balance, individuals determine the amount of drag their rocket design will experience in flight. Pupils make modifications to increase the...

After reading an interesting account of how the X-1 aircraft was designed, built, and utilized, young engineers try their hand at constructing a paper glider version of the airplane. They cut out the plane out of a nicely designed...

Multiple representations of the varying theories of atomic structure. With these pictures and some background of the theories and scientific figures surrounding them, your class will develop a better understanding of scientific history...

Convection currents do more than just bake a cake. A quick lesson demonstrates the convection currents of the earth and how they contribute to continental drift. An animation illustrates the movement of the currents and demonstrates how...

The subduction model: helping learners understand how continental drift is possible. An animation demonstration illustrates the process of subduction through an analysis of the earth's layers. The instructor narrates the process as the...
