HP Mobile Calculating Laboratory 1

1HP Mobile Calculating Laboratory

The HP Mobile Calculating Laboratory (HP MCL) consists of one or more Fourier®

sensors, an HP StreamSmart 410, and an HP 39/40gs graphing calculator with

the StreamSmart Aplet. Investigation and understanding of mathematics and

science concepts are enhanced by the HP Mobile Calculating Laboratory, as it is

designed to simplify the collection and analysis of real-world data.

Types of experiments

The Mobile Laboratory supports a number of different types of experiments, as

shown in the table below.

Table 1-1 Types of experiments

Type Description Example

Stream Displays a live time graph (data

stream) for up to four sensors

simultaneously, at rates up to 5,000

samples per second. See Chapter 2

for details.

Two students each sing a note

one octave apart into separate

microphones; the HP MCL

displays their voice sound waves

live so their wavelengths can be

compared.

Stream/select

events Same as above StreamSmart captures the

dampened oscillations of a

vibrating rod. Students select just

the maxima of the oscillations for

further analysis.

Selected events Displays a live meter read-out for up to

four sensors simultaneously; you can

add a set of readings to your data set

at any time. See Chapter 3 for details.

Collect pH and temperature

readings from various locations

around the edge of a pond.

Events-with-entry Same as above Collect pH and nitrate readings

from various locations along a

stream; add as an entry to each

reading the distance from the

point in the stream to a runoff

drain pipe that empties into the

stream.

Log Set up a stream experiment to collect

a certain number of readings at a set

sampling rate. See Chapter 3 for

details.

Take 20 temperature readings

from a cooling cup of coffee for

10 minutes, taking one reading

every 30 seconds.

HP Mobile Calculating Laboratory

1. C h a r g e

Charge the unit. IMPORTANT! Before beginning, plug the StreamSmart 410

into your computer with the mini USB to USB cable that came in the package

with your HP graphing calculator. You will need to charge the unit for

approximately five hours. Your computer must be running for charging to

occur. DO NOT use the cable attached to the StreamSmart 410 for charging.

The low battery symbol (ã) indicates the StreamSmart 410 requires

charging. If the battery symbol appears in the upper left corner of the screen,

be sure to charge the StreamSmart 410 as soon as possible.

2. Connect

Connect a Fourier®sensor to the StreamSmart 410 using the sensor cable. The

following experiment uses the Fourier®light intensity sensor, but you can use

any sensor and still follow along with this guide. Note the sensor cable ends

have a flat side; be sure the flat side faces up on the connection to the

StreamSmart 410. Connect the StreamSmart 410 cable to the HP 39/40gs

graphing calculator. Turn on both the calculator and the StreamSmart 410.

Aim the sensor at a florescent light source. Make sure the switch on the sensor

is set to C: 0 – 600 lux.

3. Start the Application

The StreamSmart Aplet is located in the Aplet Library in the HP 39/40gs.

The user runs the HP Mobile Calculating Laboratory via the StreamSmart

Aplet. Please check online at www.hp.com/calculators to ensure you have

the latest version of the StreamSmart Aplet. See Figure 1-2 below for

instructions on accessing the application.

4. Stream

1. Once the StreamSmart Aplet starts, you will see the message, Waiting for

connection..., quickly followed by a second message, Waiting to start....

When this message appears, press the START menu key to commence data

streaming.

The data stream is a graphical representation of sensor data. The horizontal

axis represents time in seconds, and the vertical axis represents sensor data

in units of measurement. The plot window displays a number of items, as

illustrated in Figure 1-3 below.

The HP 39/40gs

The StreamSmart Aplet has the same general structure as the other HP 39/40gs

Aplets. For example, the StreamSmart Aplet has the standard Plot and Numeric

views. Table 1-2 below lists the standard Aplet views and their use in the

StreamSmart Aplet for the HP 39/40gs. Note that the standard Symbolic and

Symbolic Setup views are not used by the StreamSmart Aplet.

All of the views listed in Table 1-2 can be accessed on the HP 39/40gs via the

Views menu by pressing V.

The Statistics application

The StreamSmart Aplet works seamlessly with the Statistics Aplet on the HP 39/

40gs to provide you all the tools you need to collect and analyze data.

Once you select the data you want to analyze, the data is sent to columns in the

Statistics Aplet. The Statistics Aplet has ten columns available for data, C1 through

C9, and C0. You may choose a destination column for each sensor's data, or use

the default values provided. When you export data to the Statistics Aplet, you can

choose to follow your data into the Statistics application for analysis, or stay in the

StreamSmart Aplet to continue experimentation. In-depth analysis of the data,

including the calculation of summary statistics (for 1 or 2 variables) and modeling

bi-variate data with various fits, is performed in the Statistics Aplet. This manual

contains a brief introduction to the Statistics Aplet, but for more information about

the Statistics Aplet for the HP 39/40gs, refer to the HP 39/40gs User's Guide.
