Science Probe I Technology Activities
The study of quasars, pulsars, black holes, and nebulas
can help cosmologists understand more about the universe. Select one of
these objects to search the Internet for current research (include information
from the last five years). Obtain information that will answer the following
a.How was the object first detected and by whom?
b.How many of these objects have been discovered?
c.How many light years away is the closest one?
d.How large are the objects?
e.What is the object made of?
f.How did the object form?
It might also be helpful to correspond through e-mail or
talk in a web discussion site with an astronomer or someone who works
in an observatory to get your answers. Prepare a presentation using sky
maps, sketches, computer graphics, or other multimedia to inform your
classmates about the object you have selected. Below are web sites to
get you started:
The Web Nebulae
The Astronomy Cafe
Activity 15A – Use a word processing
program to set up the three-column table as directed in this activity.
As you read the sections, take your notes on the computer. Use a graphics
program to create your drawings; then insert them into the table in the
appropriate location in your notes. Print the data and graph, and secure
them in your SCIENCE PROBE Logbook.
Activity 15B – Use a spreadsheet
program to make the data table shown in Table 15.1 of 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 number
of sheets thick (or the number of light years). Print the final spreadsheet
with all calculations, and secure it in your SCIENCE PROBE Logbook where
you will answer the discussion questions for this activity.
