Portfolio Assessment
Can students create a Portfolio of their work
in the pH Factor? Try the assessment below, or find out more
about portfolio assessment.
Materials
What
To Do
 Have each group USE the lab
sheets and presentation sheets
to RECORD the information theyCOLLECT for each of their experiment
they do in The pH Factor. These can then be added to a group
science portfolio.
 Have the groups SORT all the solutions tested
in Mysterious Solutions by pH.
Have groups DRAW diagrams of the cups lined up in a modified
pH scale, from red to purple. Diagrams of experiment procedures
or results can also be added to portfolios.
 Have students RESEARCH pH on the Internet
using our pH Hotlist or Go
to find web pages and e-mail addresses. Keywords like "chemistry",
"pH" or "acid rain" would allow students
to begin a pH search. INCLUDE Internet information and e-mail
from experts in a portfolio.
