intelino/Voyager: 7-9 Math/Physical Science Slope Lab

PocketLab Voyager measuring wheel hitches a ride with intelino

Introduction

Math students are typically introduced to the concept of slope in the 7th grade, learning that slope has to do with steepness. By the 8th grade many learn how to calculate the slope of a line as the rise divided by the run or rise over run. If the rise is positive, then the slope is positive (sloping upward). On the other hand, if the rise is negative, then the slope is negative (sloping downward). If the line is horizontal, then the slope is zero.

intelino / Voyager Lab: Stopping Distance vs. Speed

Submitted by Rich on Tue, 08/20/2019 - 00:42

intelino/Voyager interface for a study on stopping distance and speed

Introduction

Have you ever been told not to follow too close to the driver ahead of you? To keep a safe distance? To abide by the "3-second rule"? To keep a distance of at least one car length for every ten miles per hour of speed? These questions all deal with the issue of stopping distance versus speed in order to avoid crashes. A great way to investigate the relationship between stopping distance and speed is to interface Voyager with an "intelino® smart train". Designed for all ages, intelino is intuitive with its app, has bui

intelino / PocketLab: Velocity vs. Impulse to Stop

Submitted by Rich on Sat, 08/17/2019 - 15:34

Introduction

While driving at 40 mph, you see a red stop light ahead. You press your brakes for several seconds, gradually coming to a stop. A little later on the same road at 40 mph, you approach another light, this time green. While approaching this light, it suddenly changes to yellow. You make a split-second decision to put on your brakes to avoid going through a red light. With the brakes applied quite hard, you quickly stop, waking up your sleeping friend in the front passenger seat.

intelino/PocketLab: Impulse & Change in Momentum

Submitted by Rich on Sun, 08/11/2019 - 20:59

Lab setup for this AP physics lesson on impulse and change in momentum

Introduction

This lesson features Voyager and the "intelino® smart train" in a lab for AP physics students. 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. Students are challenged to design and carry out an experiment to show that impulse is equal to change in momentum when Voyager is mounted to an intelino smart engine that suddenly reverses itself.

intelino/PocketLab: Relative Velocity Lab Grades 6-9

Submitted by Rich on Wed, 07/31/2019 - 15:47

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

Voyager and and intelino smart train help in teaching angular velocity concepts

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

PocketLab Voyager and the intelino smart train

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

Submitted by Rich on Sun, 07/07/2019 - 19:47

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

Exponential damping with the PocketLab Mini HotRod

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
