Question

Yosef is playing with different kinds of rubber bands. Some are very narrow, and some are quite wide. Yosef is curious about the rubber bands and develops this scientific question: Does the width of a rubber band affect how easily it can be stretched? He decides to develop a hypothesis to test this scientific question. What could Yosef’s hypothesis be?

Answer 1

Yosef's hypothesis could be:
The larger the width of a rubber band, the harder it is to stretch it. 

Answer 2

Answer:

The correct answer will be-The narrow bands are easier to stretch compared to wider bands is the correct answer.

Explanation:

A scientific hypothesis is a prediction or an idea based on the previous knowledge which could be tested through experiments. The scientific hypothesis represents the limited explanation of the phenomenon.

In the given question, Yosef was playing with the rubber bands of various width from narrow to wide which lead to the observation that width of rubber bands affects the stretching ability or elasticity of the band.

After asking the question, Yosef could have done background research on the question and framed the hypothesis which could be the "The narrow bands are easier to stretch compared to wider bands".

Thus, The narrow bands are easier to stretch compared to wider bands" is the correct answer.
