Question Column What is quantitative data?

Answer Column numbers

Question Column Name a room in Orchard that you could hear an echo.

Answer Column Gym, cafeteria

Question Column Explain 2 ways you can use a guitar to make different pitches.

Answer Column Rate of Vibration, Frequency, thickness of string, tension of string, change the length of the string.

Question Column If you shine an orange light on white, orange and black construction paper, which color paper will be the hottest and why?

Answer Column The black paper because it absorbs the orange light. The orange and white paper reflect the orange light.

Question Column Can sound bend? And why?

Answer Column yes. It travels in all directions.

Question Column What is frequency? How does it affect pitch?

Answer Column The number of vibrations per second The more vibrations, the higher the sound

Question Column Name a room in Orchard that you will never hear an echo.

Answer Column A classroom – absorption of sound

Question Column There are three bottles that have water in them. Bottle A has the lowest sound. Bottle B has the highest sound. Explain how much air is in each of the 3 bottles.

Answer Column A gas

Question Column Why does light travel the fastest in a gas?

Answer Column No molecules to get in the way

Question Column Draw a diagram of a light ray reflecting off of a flat surface.

Answer Column Incoming angle should the same as the out going angle

Question Column Think of 5 tuning forks. The first one is the smallest and the last one is the longest. How will the pitch change from the first to the last and why does that happen?

Answer Column The first one will be the highest because it is the shortest and the last one will be the lowest because it is the longest.

Question Column Think of our sound lab where we used a tong. Dep., fishing line and a pencil. Which placement of the pencil will produce the highest pitch? Why

Answer Column Closest to the tong. Dep. Because it is the shortest length.

Question Column True or False Can sound travel through opaque materials?

Answer Column True

Question Column Why does sound travel worst in air?

Answer Column Molecules are spread out and don’t vibrate very well

Question Column Why does a stick in a glass of water look broken?

Answer Column The light is refracted when it hits the water.

Question Column What is pitch?

Answer Column How high or low a sound is.

Question Column Why does sound need matter or molecules?

Answer Column The molecules or matter vibrate which causes sound

Question Column A flute has holes at different distances from the mouthpiece. How does this create pitch?

Answer Column More holes covered the longer the length and the lower the sound. Fewer holes covered the shorter the length and the higher the sound

Question Column Look at the chart. What conclusion can you draw from this chart? Air Temperature (deg. C)Vibrations per second

Answer Column The hotter it gets the more vibrations
