different stages in its life. Since the larvae go through 4 different stages it is called complete metamorphosis. The first stage the species has being in an egg. After the mother Craneflies eggs are fertilized‚ they then release their eggs over temperate waters. As the eggs are released they fall into the water and will descend into the stream bed.

Introduction In order to further understand the relationship between temperature‚ radiation‚ and energy output we conducted a black body experiment in order to experimentally confirm the Stefan-Boltzmann constant. A black body is an object which allows all entering radiation‚ without reflection‚ to enter the object‚ absorbs all of the radiation‚ and subsequently releases radiation based on its own constant temperature. Another key factor is this absorption happens at all various wavelengths and
