-scientific discoveries, (such as advances in the study of physics) lead to technological discoveries, (such as the invention of the transistor). it can also be the other way around, the use of transistors led to advances in other scientific fields such as computer science and space science
Advanced science projects and independent scientific research are invariably subject to much scrutiny. Other scientists in the field will be looking at your work and will expect that the data has been rigorously analyzed. But rigorous analysis also requires careful experimental design. If you don't spend time thinking about the types of observations you'll be making, the likely outcomes, and how you can evaluate your data to differentiate statistically between outcomes, you might fail to car
Antonie van Leeuwenhoek used single-lens microscopes, which he made, to make the first observations of bacteria and protozoa. His extensive research on the growth of small animals such as fleas, mussels, and eels helped disprove the theory of spontaneous generation of life.
