Thermos Design Challenge

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.

Introduction

Here is a physical science lab for junior high students that brings out the S, T, E, and M in STEM -- S for the science of relative velocity, T for the technology of sensors, E for engineering an experiment design, and M for the mathematics used in analyzing data.  How can all of this be accomplished?  Simply interface  PocketLab Voyager

Introduction

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

Introduction

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

Introduction

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

Damped Simple Harmonic Motion

Introduction

Damping causes oscillatory systems to dissipate energy to their surroundings.  Frictional losses are quite common in mechanical systems and result in damped simple harmonic motion.  For example, when a child stops pumping a swing, the amplitude of the oscillations gradually decay toward zero.  The same thing happens to a mass that hangs from an oscillating spring.  It is quite common for the amplitude of such oscillations to exhibit a behavior that is negative exp

Particulate matter and its Health Effects

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.

How much Carbon Dioxide do you Produce? (MS-ESS3-4 )

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.

The Negative Exponential Nature of Damping

Introduction

Damping causes oscillatory systems to dissipate energy to their surroundings.  Frictional losses are quite common in mechanical systems.  For example, when a child stops pumping a swing, the amplitude of the oscillations gradually decay toward zero.  The same thing happens to a mass that hangs from an oscillating spring.  It is quite common for the amplitude of such oscillations to exhibit a behavior that is negative exponential over time, as shown in Figure 1.  The graph indicates that if we take the amplitude at time t=0 to be 1, then the amplitude at time
