Climate change is at the forefront of environmental concerns and it often revolves around carbon dioxide in the atmosphere and its effect on average temperature. However, carbon dioxide is not only increasing in the atmosphere but in the ocean as well. The source of this carbon dioxide is the much talked about atmospheric carbon dioxide, as carbon dioxide is soluble in water.
In these two design challenges, students will design and construct their own thermos/storage device using craft materials and measure its effectiveness to insulate a liquid with a PocketLab temperature probe. These activities are aligned with two middle school NGSS standards and are a great open-ended, hands-on project for students to engage their critical thinking and engineering skills.
Are you looking for some great physical science activities for 4th grade through junior high school students? If so, it would be well worth considering interfacing PocketLab Voyager with the "intelino® smart train". Designed for all ages, intelino 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. In this lesson, your students are challenged to design an experiment to measure intel
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
First, what is particulate matter (PM)? Particulate matter is a mixture of solids and/or liquids suspended within the air. These solids and liquids are too small for the eye to see, however, if they're in a high enough concentration it will often look like a haze in the air. The particles that make it up can be anything from pollen and dust to even molecules of water. The number at the end (ex. the 10 in PM10) is the upper limit of the particles’ diameter. A size comparison produced by the US EPA can be seen below.

Engineering Crash Cushions to Learn Newton's Third Law
Newton's Third Law Example
Car crashes are a dangerous example of Newton's Third Law. The car exerts a large force on the wall and the wall then exerts a large force back onto the car. Civil engineers are always trying to think of new ways to make highways safer. Building crash cushions along highways that reduce the impact force of the collision will, according to Newton's Third Law, also reduce force experienced by the passengers of the car. This can save lives.
Introduction to Crash Cushioning
In addition to automobile features that promote road safety, there has been and continues to be a great deal of work on highway features that save lives. An earlier lab entitled Crash Cushion Investigation, submitted by PocketLab, makes use of the PocketLab HotRod to investigate crash cushioning similar to that shown in Figure 1.
In this experiment, middle school and high school students use their PocketLabs learn about angular velocity -- the rate of change of angular position of a rotating body.
What is a Theremin?
A theremin , named after its Russian inventor in the early 1900's, is an electronic musical instrument that is controlled without any contact by the musician. Volume is controlled by moving one hand near one antenna, while pitch is controlled by moving the other hand near a second antenna. The sound is generated by a pair of high-frequency oscillators.
