strong weak
how does heat affect a batterys life?
which battery brand is the best?
what type of wheel material is the most durable?
how do ghosts move through space?

Explanation:

A strong scientific question is testable, specific, and can lead to further investigation. "How does heat affect a battery's life?" is testable by varying heat levels and measuring battery - life, so it's strong. "Which battery brand is the best?" is subjective as "best" can mean different things (cost, lifespan, etc.) and lacks specificity, so it's weak. "What type of wheel material is the most durable?" is testable by subjecting different wheel materials to wear - tests, so it's strong. "How do ghosts move through space?" is about a non - testable, non - scientific concept (since ghosts are not scientifically proven to exist), so it's weak.
