demonstrate that the flow of electricity in circuits requires a complete path through which an electric current can pass and can produce light, heat, and sound
demonstrate that light travels in a straight line until it strikes an object or travels through one medium to another and demonstrate that light can be reflected such as the use of mirrors or other shiny surfaces and refracted such as the appearance of an object when observed through water
explore the uses of energy, including mechanical, light, thermal, electrical, and sound energy

Q.
A student designs an experiment to test the effect of the width of a piece of elastic on the elastic’s ability to stretch. The student selects four pieces of elastic with different widths but the same length. The student then attaches blocks with different masses to the pieces of elastic. The results of the student’s experiment are shown below. What should the student do to improve this experiment?
