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.
