Help In Using the EA100 Data Collector
Quick Look Reference to Using the EA100 Data
Collector: A valuable document to get you started.
Manual Setup of the EA100: Another document
to help you get started with the EA100.
Demonstration Packet: The Quick setup guide
along with 5 very simple activities. This is a perfect document if you are
doing a quick training for a group of teachers for staff development.
Ea100 Workshop Manual: A complete overview
of the EA100, using it as a multimeter, datalogger, as well as transmitting
to a calculator The format is setup for a full days worth of activities.
And should be used with the "Bringing the World to Your Fingertips" document
which is also listed on the site. (Set of 16 labs by Joe Schumaker).
Informal Uses for the EA100: A resource
document which brainstorms for interesting things to measure with various
probes, as well as listing for websites that have valuable activities.
Activities for EA100 Data Collection
EA100 Activities Developed by Gloucester
High School Workshop
1. RADAR Racers re-design: Use
a car, a track, and a motion detector to calculator velocity and acceleration
created by an incline plane.
2. Cool Cans: Use rock salt to influence
the rate of cooling on a can of soda, measure this compared to a can
cooled with just ice. An EA100, calculator, cans, rock salt, and ice
3. The Electric Eggplant Shirt: To
use different colors of material to see the rate of heat absorption.
Dfferent Shirts are used for this experiment, an EA100, 9850G,
and Temperature probe.
4. The Lighter Side of Velocity: Use
an incline plane, a car, and light probes to calculate velocity
as it is rolling. This incorporates sampling from two channels
5. Sea Cell: The student will be able
to: (1) determine the relationship between electrolyte concentration
and voltage within a cell (2) accurately record, organize, and analyze data
(3) demonstrate proper and safe use of chemicals and equipment (4) mathematically
manipulate data to graphically display it using a graphing calculator.
(EA100, voltage probe, and chemistry lab equipment are
6. Tri-Bubbles: You will measure and
analyze the dissolved oxygen (DO) content in varying salinity water samples
at 5°C temperature intervals using temperature and dissolved oxygen
7. Hot Hosts in the Composts: Compare
how temperature and depth of placement affects the rate of decay of items
in a compost pile. EA100 & Temperature probe is used.
8. Absorption and Radiation of Heat Energy:
Compare how light vs dark, and soil vs water affect the rate
of temperature change from radiation energy.
9. Penny Power: With a few simple
materials we will make a simple battery called a voltaic pile. We will use
our EA-100 data collector and voltage probes to Asee@ how much electricity
we can generate. This movement of electrons will be measured in volts (v)
or millivolts (mv). Materials: Copper coins (at least 10 the same size);
Cup; Salt; Water; Aluminum foil or zinc washers; Kitchen paper towels; Two
pieces of insulated Cu wire (~6 in. long); Adhesive tape; Scissors; Pencil;
EA-100 data analyzer; voltage probe. (pennypower.doc)
10. Jussst Right: Santa is always
in a hurry on X=mas Night. Wouldn=t it be nice to leave him a recipe for
hot cocoa that=s not toooo hot and not toooo cool, but jusssst right ! With
a thermos of hot water, a thermos of cold water, a packet of cocoa mix, and
a little mathematics you can do just that. EA100 and temperature probes are
11. Potato Polarity Tester: Electrolysis
is the passing of an electric charge through certain conducting liquids called
electrolytes to produce a chemical change. The current is conducted by the
migration of positive ions (cations) to the cathode (negative electrode)
and negative ions (anions) to the anode (positive electrode). Reactions take
place at the electrodes by transfer of electrons to or from them. The
electric current generated by the battery used in this experiment will cause
electrolysis of the water in the potato.
12. Walk That Line: Graphs are used to describe
everyday problems or events. The ability to see and understand this information
is your key to the world of technology. Moving back and forth in front of
the motion detector will generate a graph describing your movement. Our objective
is to be able to describe someone=s motion by interpreting their graph.
EA100 and motion detector are used with Realtime programs.
