This document discusses various topics related to science including scientific investigations, reporting and analyzing data, science and technology, and the process of engineering and design. It explains that scientists make hypotheses and inferences to explain their observations and discoveries. Data is analyzed using tables, graphs and computer simulations to help scientists run experiments and present their findings. The document also discusses how technology has advanced due to science, allowing fewer farmers to grow enough food for more people. Both science and technology have limitations in addressing moral and ethical issues. Constraints, whether natural or socially set, influence engineering and design.
