Sensors for Forest Fires

Introduction to Forest Fires

Forest fires are a common natural disaster within western North America and pose a serious risk to many communities both nearby due to direct danger of the fire, as well as far away in the form of air pollution. Currently, in many places, some form of government employee will be in charge of looking out for forest fires and once identified, satellites and computer programs can be used to track its progression and predict where the fire will spread and where the smoke cloud will go.

The Momentum Pendulum

The momentum pendulum is shown in Figure 1.  A frame (red) to hold the pendulum was printed on a 3D printer.  The STL file in included with this lesson.  The frame is solidly attached to the PocketLab HotRod with three damage-free hanging strips.  A roughly 3" diameter  wood ball with a screw eye attached to the top of the ball is hung from a bifilar suspension so that the ball will swing in a plane.  Two small holes at the top of the frame provide an easy way to prepare the string suspension.  The smaller set of wheels are used with the HotRod, and

Competing Pendulums

The two pendulums shown in Figure 1 were printed on a 3D printer.  The .STL file is included with this lesson so you can print them with your 3D printer.  They have the same length, same mass, and same thickness.  They swing about a piece of metal rod from a coat hanger.  To provide a rigid support, the rod has been attached to a ring stand.  A tiny magnet has been taped to the bottom of each pendulum.  PocketLab Voyager's magnetic field sensor keeps track of the motion as the pendulums swing back-and-forth.  What is your prediction as to which one has

Simple Harmonic Motion Demonstration Machine

Introduction

In a well-known 1938 book entitled "Demonstration Experiments in Physics", editor Richard Sutton describes a device that produces simple harmonic motion (SHM) mechanically.  With today's tremendous growth in the 3D printing industry, such a device can now be easily constructed for classroom demonstrations of SHM.  Couple this device with PocketLab Voyager and you can obtain real-time graphs describing the motion.

Background Information about Ozone

Ozone (O3) in our atmosphere is both good and bad. There is a helpful saying to remember is, “Ozone: good up high, bad nearby.” The “good” ozone is ozone high in our atmosphere that is part of the ozone layer. The ozone layer protects us from the sun’s ultraviolet rays. “Bad” ozone is ozone that occurs at ground level, where it can be inhaled. Ground level ozone is a pollutant and creates smog.
