Question
that describes developing a hypothesis. hint: to develop a hypothesis, you use logic and research to propose a possible explanation. watching boats sue watched boats on the river. she noticed that some of the boats were v - shaped, and other boats seemed to have flat bottoms. she speculated that the shape of the boat bottom might affect how much weight the boat could hold, so that flat - bottomed boats would hold more weight. so, she decided to make several aluminum foil boats to float in the bathtub. she made ten boats with flat bottoms and ten boats with v - shaped bottoms, and then she kept track of the number of pennies it took to sink each boat in the water. sue compared the average number of pennies it took to sink the boats in each of the two groups. because the flat - bottomed boats held more pennies, she reasoned that the shape of the boat bottom affected how much weight the boat could hold
The problem involves Sue observing boat shapes, formulating a hypothesis (flat - bottomed boats hold more weight), conducting an experiment (making aluminum foil boats, testing with pennies), and analyzing results. This process of formulating a hypothesis, testing it through an experiment, and drawing conclusions is a key part of the scientific method, which is central to Natural Science, specifically in subfields like Physics (related to buoyancy and forces on boats) or a more general scientific inquiry subfield. The hypothesis development here is based on observation and logical speculation about the relationship between boat bottom shape and weight - holding capacity, and then an experimental approach to test it.

The process described shows Sue developing a hypothesis (that the shape of the boat bottom affects weight - holding, with flat - bottomed boats holding more), testing it via an experiment (making boats, adding pennies), and analyzing results. This is an example of the scientific method in action, typical of Natural Science (e.g., Physics - related to buoyancy) where hypothesis development and experimental testing are key.
