Another option is the African dwarf frog, which is a small, aquatic amphibian that can thrive in a small tank with minimal care. Additionally, certain species of tarantulas, such as the Chilean rose hair tarantula, are low-maintenance and do not need a large terrarium space. **

Systematic observation in field research involves the structured and planned collection of data through direct observation of a specific phenomenon, often using predetermined categories or criteria. On the other hand, participant observation involves the researcher immersing themselves in the social setting being studied, actively participating in the activities and interactions of the group being observed. While systematic observation allows for a more objective and standardized approach to data collection, participant observation provides a deeper understanding of the social context and dynamics by experiencing it firsthand. Ultimately, the main distinction lies in the level of involvement and interaction between the researcher and the subjects of the study. **

Systematic observation in field research involves the structured and predetermined collection of data based on specific variables or behaviors of interest. Researchers use predefined criteria to guide their observations and ensure consistency in data collection. On the other hand, participatory observation involves the researcher immersing themselves in the social setting being studied, actively participating in the activities of the group being observed. This approach allows the researcher to gain a deeper understanding of the context and culture of the group, but may be more subjective and less structured compared to systematic observation. **

Trainings that are easy typically involve clear instructions, simple concepts, and familiar topics. Hands-on trainings that allow for practice and immediate feedback are also generally easier to grasp.
