Science Probe I Technology Activities
Chapter 4
Internet
Perform an Internet search to find out how catalysts are
used in the manufacture of products such as tires, plastics, fabrics,
pharmaceuticals, and gasoline. Describe the role the catalyst plays in
the chemical reactions for producing these materials. Communicating with
a chemist working in the field or with one who is quite familiar with
the process, by e-mail or in a web discussion site, may help you gather
information. Prepare a multimedia presentation that includes chemical
equations to demonstrate to your classmates what role catalysts play in
the manufacture of the material. Below is a web site to get you started:

Application Software
Activity 4B – Use a spreadsheet program
to make your data table, as shown in Table 4.1 of this activity. Include
two additional columns, Energy given off (in j) and Energy per gram of
peanut (in j/g of peanut). Record the data in the spreadsheet as you perform
the activity. Use the mathematical functions of the spreadsheet to do
the calculations automatically as you enter the data for Change in temperature,
Mass of peanut burned, Energy given off, and Energy per gram of peanut.
Print the final spreadsheet with all calculations, and secure it in your
SCIENCE PROBE Logbook where you will answer the discussion questions.
Activity 4C – Use a spreadsheet program
to make your data table as directed in this activity. Record the data
in the spreadsheet as you perform the activity. Use the graphing function
to plot the graph of time and temperature as directed in Discussion step
3 of the activity. Print the graph, and secure it in your SCIENCE PROBE
Logbook where you will answer the discussion questions.
Activity 4D - Use a spreadsheet program
to make your data table. Set up the data table as shown below.
| Block |
Number of Blocks |
Total Surface Area (cm2) |
| Large |
1
|
|
| Small |
8
|
|
Record the data in the spreadsheet as you and your classmates perform
the activity. Use the mathematical functions of the spreadsheet to do
the calculations automatically as you enter the data for total surface
area of the large block and the small blocks. Print the data table, and
secure it in your SCIENCE PROBE Logbook where you answer the discussion
questions.
Probeware
Activity 4B - Use a temperature probe
to measure the temperature of the water in the beaker. Set the application
software to measure the temperature every 10 second. Insert the probe
before heating the water in the beaker, and allow it to sit for a few
minutes so it can adjust to the temperature of the water in the beaker.
The application software will display the temperature. Do the Procedure
steps; when the highest temperature is reached, record this temperature.
Use the mathematical functions of the spreadsheet to do the calculations
in this activity. Print the graph, and secure it in your SCIENCE PROBE
Logbook where you will answer the discussion questions.
