Science Probe II Technology Activities

Chapter 3

Internet

Conduct an Internet search to find information about the life, work, and experiments of one of the following people as directed by your teacher. Charles Du Fay, Michael Faraday, J. J. Thomson, Charles Coulomb, Alesandro Volta, or Andre Ampere. Prepare a presentation to share your findings with your classmates. Below is a web site to get you started:

Application Software

Activity 3B – Use a word processing program to make the list for your group as directed in this activity. Set up a chart (data table) to record the results of rubbing the different materials together. Transfer this document to a presentation program, and share your results with the other groups in the class. Print the list and chart, and secure them in your SCIENCE PROBE Logbook where you will answer the discussion questions.

Activity 3F – Use a spreadsheet program to make the data table as directed in this activity. Record the data in the spreadsheet as you perform the activity. Use the mathematical functions of the spreadsheet to do the calculations for finding the ratio of voltage to amperage (V/A). Print the final spreadsheet data table, and secure it in your SCIENCE PROBE Logbook where you will answer the discussion questions.

Probeware

Activity 3D – Use a voltage probe connected to a computer or calculator in place of the multi range meter. Connect the probe in the same manner as directed for the multi range meter. The computer or calculator application software will display and record the voltages as you test the circuits. When the activity is completed, print the data table that was recorded by the application software and secure it in your SCIENCE PROBE Logbook where you will answer the discussion questions.

Activity 3E – Use a current probe connected to a computer or a calculator in place of the multi range meter. Connect the current probe in the same manner as directed for the multi range meter. The computer or calculator application software will display and record the currents as you test the circuits. Print the data table that was recorded by the application software, and secure it in your SCIENCE PROBE Logbook where you answer the discussion questions. Record your observations, diagrams, and answers to questions in your SCIENCE PROBE Logbook as you progress through the activity.
