At
first, we wanted to so the same experiment but with mosquito eggs
instead. However, the Ministry of Environment did not allow us
to breed mosquitoes.
We
changed the topic and wanted to use tadpole eggs. Although we
could get tadpole eggs, but the eggs did not hatch, thus delaying
our experiment.
We
had to throw away the eggs and bought tadpoles that were about
three weeks old for 50 cents each.
