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

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

How does adding thermal energy affect the particle motion of a gas? 

NGSS Alignment: MS-PS3-4

The disciplinary core idea behind this standard is PS3.A: Definitions of Energy and PS3.B: Conservation fo Energy and Energy Transfer. In PS3 the standard specifically looks at how temperature is a measure of the average kinetic energy of the particles of matter. This leads to the conclusion that the temperature and the total energy of a system depend on the type, states, and the amounts of matter present.

Investigating an Object’s Motion: Newton's First Law and Second Law

Using a Half-Atwood Machine for Newton's Second Law

The Half-Atwood Machine consists of a cart and a weight connected by a string. It can be a perfect tool for tackling NGSS MS-PS2-2, which is centered around planning an investigation into Newton’s Second Law. Specifically, the standard says: 

Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object. 

Egg Drop Experiment with Data

We can take an egg drop further by adding sensor data collection. Normally an egg drop is a “pass or fail” activity, and collecting data is difficult. With an sensor in place of the egg for trial runs, students can refine their designs with real life data.

Carnival Games

Most everyone enjoys a carnival!  Some like the food--from cotton candy, to funnel cakes, to ice cream.  Others enjoy rides such as the carousel, Ferris wheel, and bumper cars.  Many like to test their skills in games like "Milk Bottle", "Balloon and Dart", and "Ring Toss".  One of the most well-know skill games is "High Striker", sometimes called "Ring the Bell" or "Strongman Game".  This game is commonly played by guys trying to impress girlfriends and wives with their macho strength.  In this game, a large mallet is used to strike one end of a lever.  Th
