6. Question 4 Sam conducted an experiment by placing a thermometer on a white piece of paper and a black piece of paper. He placed the two pieces of paper in the sun. He collected the following data in five minutes. a.Looking at the data, explain the results of the experiment. b.Explain why there is a difference in the two ending temperatures. A.The black paper’s temperature increased by four degrees each minute. The white paper’s temperature increased by two degrees each minute. B.The black paper has a higher temperature because black absorbs light and heat. The white paper is cooler because it reflects light and heat.

7. Question 5 Design an experiment in which you demonstrate conduction. Answers will vary Check Answer

8. Question 6 Contrast reflection and refraction. Reflection is when light bounces off an object. Refraction is when light changes speed as it passes from one state of matter to another (the light appears to bend). Check Answer

9. Question 7 What is occurring to the light beam in this picture and why is a rainbow created? Refraction – The prism is bending the white light beam, causing all the colors that make up white light to appear. Check Answer

10. Question 8 Light travels in _______________. Straight lines Check Answer

11. Question 9 Label each picture transparent, translucent, or opaque. Explain how much light is allowed to pass through each object. Translucent – lets some light through Transparent – lets most light through Opaque – lets no light pass through Check Answer

13. Question 11 What part of the banjo will vibrate, creating the sound? the strings Check Answer

14. Question 12 The __________ the vibrations of an object, the ___________ the pitch. The faster the vibrations of an object, the higher the pitch. The slower the vibrations of an object, the lower the pitch. Check Answer

15. Question 13 Recorded on this graph are vibrations per second for four different sounds. Order the sounds from lowest to highest. 1, 4, 2, 3 Check Answer

16. Question 14 Create the chorus of a song that explains how we hear things. Answers will vary. Check Answer

17. Question 15 Design a demonstration that shows how pitch and vibration speed are connected. Demonstration must show that the faster the vibration, the higher the pitch and the slower the vibration the lower the pitch. Check Answer
