2. Second blank: After testing, they are shown to be "valid" (or "true", but "valid" is more precise for scientific concepts).
3. Third blank: Theories are proven accurate through "experiments" (scientific investigations to test hypotheses).
4. Fourth blank: Laws are proven through "observations" (since laws often describe consistent patterns seen in nature).
