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 Device


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 are needed.

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 simultaneously.  

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 required)  

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 probes.

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 used.  

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.
