>Dear Ms. Delancy and Class,

Dear Miss Hurley and Class,

        It is always great to hear from other classrooms like yourselves.
It is so amazing how the internet has truly made the world into one large
global classroom.(:I)

        The average temperature of the tadpole's water inside of our
classroom was charted as being 76 degrees F.  The average temperature of
the tadpole's water in the fish pond outside was charted at being 83
degrees F.  These temperatures were read and charted solely by the second
grade magnet students.  (There will be a slight margin of error. However,
not by much). Our tadpoles that were outside developed fully into little
frogs in four weeks. The tadpoles that were inside our classroom developed
into frogs in five  weeks.

         When we took the tadpoles out of our school's the fish pond, they
were all  (basically) at the same stage of development.  However, you must
consider that when we found them, their developmental stages were likely
more advanced than yours.  Our tadpoles were already swimming frantically
in the fish pond.  Moreover, the temperature differences and weather
conditions among our two states is also a very important variance.  Down
here in Florida, we have sub-tropical weather almost year round with only a
few exceptions (unexpected cold front coming in from the mid-western
states). Weather conditions have a great effect on the growth of tadpoles.

In Conclusion

          Tadpoles develop faster in warm tropical environments. It is a
proven fact. However, all of our temperature findings and tadpole growth
rates will be some what different, which is O.K.  This is mainly because of
the variances in our outdoors weather, the air condition settings in each
of our classrooms, the developmental stages of our tadpoles when we find
them and the way that we take care of them.  Our tadpoles were stored in
water that was scooped out of our fish pond.  It smelled really bad.
Nevertheless, we wanted to make this experiment as factual as possible.

        The main purpose of this project was to engage the students in
inquiry science that actually involved field study.  Students learn best
and remember more when science irquiry lessons involves elements of self
discovery and not just copying information out of a text book. Students
really need to be able to  enjoy science. And, it takes wonderful teachers
like you, to make this possible. (:I)

        Good Luck With Your Experiment!  And, as I said before, it is truly
wonderful to hear from other classrooms.  I hope that you and I can share
information again in the future. Next year I will be teaching K/1 students,
only! (:I)
