EVERYDAY SCIENCE

Detailed explanation-1: -The statement; “Atoms are made of protons, neutrons, and electrons. Although we can’t directly see these particles, this structure explains many experimental observations” is a theory. Scientific laws are crafted from observations that have been severally demonstrated to be true.

Detailed explanation-2: -The four sources of new knowledge include intuition (beliefs), authority (the influence of someone with more experience), rational induction (relating to previous knowledge or tying two ideas together to create a new one), and scientific empiricism (programmatic research).

Detailed explanation-3: -The main purpose of a scientific investigation is to build knowledge. Through observation and experimentation, researchers can find explanations for natural phenomena and apply their findings to solve real-world problems.

Detailed explanation-4: -Answer and Explanation: The development of scientific knowledge requires experiments. Experiments are procedures which are carried out to determine if a proposed explanation for a natural phenomenon is true. Without rigorous experimentation scientific explanations would be nothing more than pure speculation.

Detailed explanation-5: -This is the easy part – scientific knowledge is ‘what you know’. For instance, you might understand how and why the water cycle works, what part of a soundwave indicates how loud it is (hint: it’s the height!), how plants use the energy from sunlight to make their food on sunlight, and so on.
