Grade 5 Phase Changes

Open Ended

Why is it important to use our knowledge of science to help others and make the world a better place?

Multiple Choice

Which of the following best describes why phase changes are significant in science?

• They help us understand how matter behaves under different conditions.

• They only occur in laboratories and have no real-world applications.

• They are important for cooking but not for other activities.

• They are only related to temperature changes and nothing else.

Multiple Choice
