Question

Which of these hypotheses would be the most practical to test in a classroom?

1) If all of the types of seeds in the world were weighed, the heaviest seeds would have the greatest chance of germinating.
2) If the fossilized remains of every type of known dinosaur were compared, the tallest dinosaurs would be plant eaters.
3) If four samples of mold are grown on bread with four different concentrations of sugar added, then the mold with the lowest amount of sugar will grow the least.
4) If samples of rocks from each of the solid planets in our solar system were tested, the planets closest to the Sun would have the best chance of containing some form of life.

Answer 1

The most practical hypothesis to test in a classroom is the one involving the growth of mold on bread with various sugar concentrations, as it is safe and feasible to conduct in a classroom environment.

Step-by-step explanation:

The most practical hypothesis to test in a classroom would be: 'If four samples of mold are grown on bread with four different concentrations of sugar added, then the mold with the lowest amount of sugar will grow the least.'

This is a manageable experiment that can be performed with basic supplies and within a relatively short timeframe. It involves controlled variables (amount of sugar), measurable outcomes (amount of mold growth), and is safely conducted within a classroom setting.

This type of experiment aligns well with teaching students about scientific methods, such as forming hypotheses, conducting experiments, and analyzing results.
