What do cabbage
water and litmus paper have in common? Paper strips dipped in
cabbage water and dried can be can be used as an indicator of
pH. Predict the pH of substances, and then click on the item
to see where it falls on the pH scale. In addition to activities
and lessons, there is a clear explanation of water and pH. This
is a great starting point for elementary and middle school students
to learn about pH.
Climate Analysis Network
air and soils temperatures your students gather with other areas
of the country in real time. Sorting out relevant information
may be a bit challenging at first because so much other data
is included in the tables. However, once you understand the column
codes, you will be able to find the information for your comparison
study. All temperatures are reported in Celsius. High School
students can take this a step further by comparing other soil
data like moisture and salinity.
GLOBE is a
worldwide hands-on, primary and secondary school-based science
and education program. The program offers students the opportunity
to take measurements and report their data through the Internet.
Teachers can take advantage of the many teaching guides, Web
chats, and videos on scientific topics. All GLOBE texts and other
materials can be downloaded or copied without charge. The materials
on soil investigation are comprehensive and include activities
that teachers can implement readily into the curriculum. From
Bricks to Mud Pies, A Field View of Soil – Digging Around,
and Soil the Great Decomposer are a sample of the activities
covered. Teachers and other educators who wish to lead students

Where to Buy Science Probes
Although the students in this article used the Pasco Datalogger
and sensors, there are several companies that manufacture probeware
for schools. Many of the products are sold in bundles targeted to
specific grade levels and subject areas.
In the classroom or out in the field, the Passport Xplorer Datalogger
allows you to plug in sensors and record over 100 sets of data and
store 50,000 measurements. DataStudio lite and Ezscreen software
are included in the bundles. Passport Xplorer Datalogger and sensors
are compatible with Windows and Macintosh operating systems and connect
via a USB connection.
Not only can you use LabPro with a computer, but you can also use
it with a Texas Instruments Graphing Calculator, or as a stand-alone
data collector. The Vernier LabPro stores 12,000 data points. It
includes the DataMate calculator program, but Logger Pro software
for computers is sold separately. You have a choice of using LabPro
with Windows or Macintosh computers, connected to a serial port or
