This document provides examples of testable problem statements for experiments involving raisins, soda, eggs, water, salt, and temperature. The examples follow criteria for a strong problem statement, including being readable, testable, and containing the six essential parts of a hypothesis. Sample statements ask how the amount of soda affects raisin movement; how many bubbles it takes to float a raisin for a minute; and whether changing the type of soda affects raisin movement. Other examples examine how much salt is needed to float an egg; what water temperature floats an egg; and whether the amount of egg cooking affects floating ability.
