In a previous lesson the "intelino® smart train" was introduced, and an activity on speed for 4th grade through middle school students was presented.  In that lesson Voyager was "on board" the intelino train and collected data for measuring the speed of the train.  With students at the 4th grade level learning angle measurements in degrees and also having a solid foundation in multiplication and long division, there is

There is a new train out there - the “intelino® smart train, the classic toy train reinvented", according to the developer.  Designed for all ages, it is intuitive with its app, has built-in sensors to provide an interactive experience for the user, and is easily programmed with color snaps that allow the user to control intelino's actions.  Attach a PocketLab Voyager to the top of the intelino smart engine as shown in Figure 1, and you have a great way for children from 4th grade through middle school to s

It is almost instinctive when you first get the PocketLab Air to breathe directly on it just to see what happens. As seen below, of the PocketLab Air's seven sensors five of them detect changes from a direct human breath. These parameters are carbon dioxide, particulate matter, temperature, humidity, and pressure. The most interesting of these is the sharp rise in carbon dioxide which as the most important greenhouse gas brings about strong connections to the topic of climate change.

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. This allows us to evacuate individuals who may be in danger and minimize loss of life.

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

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.

Background Information on Particulate Matter

Particulate matter consists of small particles suspended in the atmosphere. Dust, pollen, sea salt, soil particles, mold, soot, smoke, and other fine substances create a mixture of particulate matter that we inhale with every breath. According to the EPA, particulate matter greater than 10 micrometers is generally filtered away in our nose and throat. Particulates less than 10 micrometers can often pass into the lungs.

Background Information

Carbon dioxide circulates naturally in Earth’s atmosphere as part of the carbon cycle (the process in which carbon dioxide is exchanged between the atmosphere, oceans, soil, plants, and animals). According to the EPA, since the industrial revolution, humans have altered the carbon cycle through activities like burning fossil fuels, which adds CO2 to the cycle, and deforestation which reduces natural ways in which CO2 is removed.
