The exam evaluates biology, chemistry, and physics concepts, including the excretory system, thermal energy transfer, sound wave properties, and food web dynamics. Key topics cover tectonic plate evidence, the Periodic Table, atomic structure models, and convection currents. Investigations include calculating density, interpreting sound frequencies, modeling collisions for Moon formation, and observing variation in plant growth. Practical applications emphasize resistance calculation, nitrate use in plant growth, and safety measures during experiments. Keywords: biology, chemistry, physics, STEM education, excretory system, sound waves, atomic models, tectonic plates, resistance, convection, experimental design.
