Seeing the Invisible
Students will be instructed to make an observation of a flower (tulip) given the one stipulation that they will only be allowed to detect the parts of the plant that are green. Through observation and discussion, students will be led to understand that only seeing parts of the flower leads to an incomplete and even inaccurate understanding of its structure. Students will construct their own knowledge of the Sun emitting light above and below the visible spectrum by using UV beads to detect ultr

Volcanic Clouds and the Atmosphere
The common plastic water bottle makes a useful container for demonstrating properties of gases and liquids. As typical examples, we know that “air” is a gas (made up of nitrogen, oxygen, water vapor, ozone, carbon dioxide, and several “trace” gases) and water is a liquid. We should also note that gases and liquids are both “fluids”. That is, they can flow or change shape, rather than having a fixed shape like a solid. So what happens when a water bottle is opened? Usually not much. W

Magnetic Field Activities for the High School Classroom
The following unit is designed to acquaint the student with the magnetic field. The assumed average student has some familiarity with the uniform gravitational field of classical Newtonian dynamics and kinematics lessons. This is not required however. The unit is meant to introduce the idea of a field through investigations of magnetic fields as produced by various common magnetic materials and direct currents. The difference between a magnetic field and a gravitational field is that a gravitati

At a Crossroads: The King of Prussia Inn
recounts the history of this inn, built originally as a farmhouse in 1719 at an intersection of two roads northwest of Philadelphia, not far from Valley Forge. The inn provided hospitality to travelers when the colony was just a scattering of farms. In part because of its location, it became a prosperous tavern, inn, and social center for the evolving community of the same name.
