Science Probe I Technology Activities
Select three of the following to conduct an Internet search:
sunspots, solar flares, sunís rotation, solar winds, corona, core, photosphere,
or chromosphere. You should look for information that will allow you to
a.What are they?
b.Where are they found?
c.What causes them?
d.What current research has learned about them that was not known 30
It might also be helpful to correspond through e-mail or
talk in a web discussion site with an astronomer or someone in an observatory
to get your answers. Prepare a presentation using maps, sketches, computer
graphics, or other multimedia to inform your classmates about the topics
you have selected. Below are web sites to get you started:
NASA Solar Data Analysis Center
Activity 14A Ė In Part I, use a word
processing program to set up the three-column table as directed in the
activity for recording your groupís information. When the activity is
completed, print the data and graph and secure them in your SCIENCE PROBE
Activity 14G Ė In Part II of this
activity, substitute a Light Sensor Probe attached to a computer or calculator
in place of the solar cell and galvanometer. Use the application software
provided by the manufacturer of the probe to record the data as you perform
this activity. The application software will record the light intensity
at each of the distances. Using the graphing feature of the application
software or using a spreadsheet program, plot a graph of light intensity
on the vertical axis and the distance from the sensor on the horizontal
axis. Print the graph, and secure it in your SCIENCE PROBE Logbook where
you will answer the discussion questions.
