SCIENCE OPEN-RESPONSE QUESTIONS

Read all parts of each-open response question before you begin. Write your answers to the open-response questions in the space provided in this test booklet. For each open-response question, use the grid provided in the test booklet to create any required charts or graphs. If a question does not require a chart or graph, write your written response over the grid lines.

Write your answer to question 6 in the space provided on the next page.
Forms of Energy
6.	A. State the three forms of energy. B. Explain one way that each form of energy benefits you.

A. The three forms of energy are heat, light, and sound.

B. There are many benefits of energy, which humans receive. Heat, a form of energy, is produced by the sun, fire and fossil fuels. Heats benefits are warmth and economic resources, such as heating our homes, and fueling our cars. Light, which is also a form of energy, is primarily produced by the sun. Benefits of light are the ability to see, modern technologies, such as fiber optic cables used for communication; and scientific devices, such as telescopes, microscopes, and magnifying glasses. Also, solar energy is dependant on light produced by the sun. Finally, sound is another form of energy. Sound is produced by the back and forth movement of objects, also known as vibrations. Benefits of sound are the ability to hear and communicate with others. Also, the distance between objects or forces, can be determined by the pitch of sound. For example, you can tell how close a storm is to your home, by listening to the pitch of thunder.

Core Content:

SC-04-4.6.2

Students will:

· Analyze data/evidence of the Sun providing light and heat to Earth;

· Use data/evidence to substantiate the conclusion that the Sun’s light and heat are necessary to sustaining life on Earth.

Simple observations, experiements and data collection begin to reveal the sun provides the light and heat necessary to maintain the temperature of Earth. Evidence collected and analyzed should be used to substantiate the conclusion that the Sun’s light and heat are necessary to sustain life on Earth.

SC-04-1.2.3

Students will:

· Explain that sound is the result of vibration, a type of motion;

· Describe pitch, as a difference in sounds that are produced and relate that to the rate of vibration
