Look
at the diagram below and identify each species.
Using
the grid, measure the SCL (Straight carapace length)
for each animal.
To
find out what the SCL means, click on SCL to go to
the glossary. Use the back button or the return link
to get back to this page.
Record
each SCL in the table below the diagram. You might
print off this page before you start and enter the
data into the table by hand.
Plot
your results as a bar chart (or other suitable graphical
form) - a good idea is to plot it with increasing
size. (SEE point 10 about how to plot your results)
Repeat
the exercise but try using the CCL (Curved carapace
length) measurement.(use a bit of cotton thread!?)
Try
and work out the percentage difference for the two
different measurements.
Most
field/conservation workers use SCL but others use
CCL: why might this cause problems? (Put a note at
the bottom of your result page)
If
you have entered text below and then go to the glossary,
it will reset and you will lose your data.
Plot
all of your results on ONE A4 sheet.
Use a suitable spreadsheet program such as Excel,
although you might include your graphs and tables
in a word processing package, such as Word.
Try and take care with the presentation: if you can,
print out the hard (paper) copy in colour. You
might try and include some interesting backgrounds
or illustrations.
If
you have problems with printing ( e.g. diagram split
over a page), get help from your supervisor: set the
printing so this does not happen.
