This lesson has students build their own barometers they can measure air pressure with. In this way students learn about the development and implementation of meteorological instrumentation. Students can measure air pressure for a given amount if time (say, a week or a month) and then discuss what qualities of their barometers could possibly be improved upon. This aspect relates to engineers constantly reevaluating their work and improving upon existing methods.

This is a neat lesson for teaching students in physical science classes about simple machines, how they work, and how they benefit society. Students have to design their own simple machines that would assist in lifting an elephant onto a train car (although an different scenario could easily be substituted). Requires very few materials.

This simulation allows students to provide dimensions, angle of release, speed, and mass of an object. The simulation will calculate how far the object will travel, its range of motion, and height achieved. Students could be given a desired end result and be tasked with finding the right combination of size, speed, mass, and angle to get the correct outcome.

The NOAA EVL is a great site for accessing satellite imagery and animations of phenomena at the Earth's surface. All images and animations are public domain and free for reuse, so its a great resource for teachers to share with students and collogues.
