Students gain experience in the conduct of research, including: design of simple experiments; observation and preference elicitation techniques; the analysis of behavioral data, considerations of validity, reliability, and research ethics; and preparation of written and oral reports.
To determine that it is hermaphroditic, we performed the following experiments: observation of the pronuclear and chromosome behavior during oogenesis and early embryogenesis; observation of spermatogenesis during the fourth larval stage; investigation of sperm utilization; and investigation of phenotypic segregation after cross-mating using a chemically induced visible mutant.
Much of his life, though, was spent in experiments, observations, calculations, and dissections.

For numerical experiments, observations collected at 37 GPS stations from Iranian permanent GPS network (IPGN) are used.
My general approach develops and tests questions or models of broad theoretical interest, using field experiments, observations of large-scale species introductions, and between-system comparisons.
Several scholars emphasized the importance of practical work such as experiments, observations and excursions in teaching general science.
The experiments, observations, and even some theorizing were on the agenda at the Evolang9 conference in Kyoto and a follow-up forum in Tokyo last month.
Experiments, observations and computer simulations were grounded in scientific reflection about what should be explained in a rational manner, i.e., they largely followed the underlying scientific hypotheses.
Based on a combination of our understanding of basic laws, laboratory experiments, observations of nature, and mathematical and computer modeling, the science of climate change is compelling and strong.
