Example Activities Using Saltire and Casio Equipment

There are fun activities for all levels of scientific sophistication. Each experiment listed requires a probe, and a Casio Data Logger (EA-100 or EA-200.)

Making Natural Batteries
Your students can make simple batteries using galvanized nails, copper wire and various fruits or vegetables. They can then link them in series or parallel and measure the voltage with a voltage probe.

Experiencing Boyle's Law

Using a pressure sensor, a syringe and a small length of tubing, students can get first hand experience with the volume/pressure relationship described by Boyle's law.

Conducting Electricity
When a magnet moves through a coil of conducting wire, a current is induced in the wire. A very effective apparatus can be made using inexpensive spools of wire and simple magnets. When the magnet is dropped through the coil, students can measure the voltage induced with a Casio Voltage Probe.

Seeing Your Data

The Casio EA-100 (run by programs provided by Saltire) can sample at such a high rate that a graph of the gathered data dramatically shows the potential as the magnet passes through the coil.

Additional Activities

A manual of activities for use with the EA-100 is currently available from Saltire Scientific. This manual uses only the probes included with the Data Logger.
