5th Grade Topic 1 Question What does a prism do to light?
5th Grade Topic 1 Answer A prism takes white light, and separates the light into the color spectrum (ROYGBIV).
bends it,
5th Grade Topic 2 Question What is the difference between reflection and refraction? Give an example of each!
5th Grade Topic 2 Answer Reflection is the bouncing of light, and refraction is the bending of light!
4th Grade Topic 3 Question Which pitch has the slowest vibration and the lowest frequency? A low, medium, or high pitch?
4th Grade Topic 3 Answer A low pitch has the slowest vibration and the lowest frequency.
4th Grade Topic 4 Question How does light travel?
4th Grade Topic 4 Answer Light travels in the light differently .
straight waves . Light can travel through all mediums, and different mediums can affect
3rd Grade Topic 5 Question How is sound made?
3rd Grade Topic 5 Answer Sound is made when an object or material vibrates .
3rd Grade Topic 6 Question Describe the physical aspects of a concave and convex lens. What does each lens do to light, and how does each lens affect an image?
3rd Grade Topic 6 Answer A convex lens focuses the light when it passes through the lens. When looking through a convex lens, an image will appear larger .
A concave lens spreads the light when it passes through the lens. When looking through a concave lens, an image will appear smaller .
2nd Grade Topic 7 Question If Daniel had a thin rubber band and Emma had a thick rubber band and both of them plucked their rubber bands, what would the difference be in sound?
2nd Grade Topic 7 Answer Daniel ’ s thin rubber band would create a higher pitched sound . ( Faster vibrations .) Emma ’ s thicker rubber band would create a lower pitched sound . ( Slower vibrations .)
2nd Grade Topic 8 Question Describe transparent, translucent and opaque. Give an example of each.
2nd Grade Topic 8 Answer Transparent objects let all of the light through. Translucent objects let some light pass through, and opaque objects do not let any light through.
Transparent- window Translucent- lamp shade Opaque- mirror
1st Grade Topic 9 Question What is pitch?
1st Grade Topic 9 Answer Pitch is how high or low a sound is. A flute would be an example of an instrument that creates a high pitch sound, and a tuba would be an example of an instrument that creates a low pitch sound.
1st Grade Topic 10 Question What is frequency? How do you create high frequency? How do you create low frequency?
1st Grade Topic 10 Answer Frequency is the speed at which something vibrates (or the number of vibrations per unit of time).
To create a high frequency, one would need fast vibrations (and we would see many crests and troughs).
To create a low frequency, one would need slow vibrations (and we would see fewer crests and troughs).
Million Dollar Question Grade Level Topic 11
1,000,000 Question Explain the difference between pitch and volume. Support your explanation by giving examples!
1,000,000 Answer Pitch is how high or low a sound is. Volume is how loud or soft a sound is. Some high pitch sounds can both be loud and soft. For example, both a kittens’ meow and a fire trucks’ siren have high pitches, but a kitten projects a soft volume, while a fire truck projects a loud volume. The same goes for sounds that have low pitches, too!
