Which law states that energy cannot be created or destroyed, only converted from one form to another?
Answer: First Law of Thermodynamics
The First Law of Thermodynamics states that the total energy of an isolated system is constant — energy is conserved.
A 9th-grade student claims that evolution means individual organisms change during their lifetime. How should the teacher respond?
Answer: Correct the misconception: evolution is the change in allele frequencies in a population over generations
Evolution refers to changes in allele frequencies across a population over generations, not changes within a single organism's lifetime.
Which force holds protons and neutrons together in the atomic nucleus?
Answer: Strong nuclear force
The strong nuclear force overcomes electromagnetic repulsion between protons to bind nucleons (protons and neutrons) together in the nucleus.
In a food web, organisms that produce their own food through photosynthesis are called:
Answer: Producers
Producers (autotrophs) are the base of food webs because they convert light energy into chemical energy through photosynthesis.
Which celestial phenomenon causes the phases of the Moon as seen from Earth?
Answer: The changing angle of sunlight illuminating the Moon as it orbits Earth
Moon phases result from the changing angle at which the Sun illuminates the Moon's surface as the Moon orbits Earth.
Which instructional approach is MOST aligned with the 5E inquiry model in science education?
Answer: Students engage in hands-on exploration before formal explanation
The 5E model (Engage, Explore, Explain, Elaborate, Evaluate) places hands-on exploration before formal explanation to build conceptual understanding.
