5. 5th Grade Topic 2 Question • What is the difference between reflection and refraction? Give an example of each!

6. 5th Grade Topic 2 Answer • Reflection is the bouncing of light, and refraction is the bending of light! Return

7. 4th Grade Topic 3 Question • Which pitch has the slowest vibration and the lowest frequency? A low, medium, or high pitch?

8. 4th Grade Topic 3 Answer • A low pitch has the slowest vibration and the lowest frequency. Return

9. 4th Grade Topic 4 Question • How does light travel?

10. 4th Grade Topic 4 Answer • Light travels in straight waves. Light can travel through all mediums, and the different mediums can affect light differently. Return

11. 3rd Grade Topic 5 Question • How is sound made?

13. 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?

14. 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. Return

15. 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?

16. 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.) Return

17. 2nd Grade Topic 8 Question • Describe transparent, translucent and opaque. Give an example of each.

18. 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 Return

21. 1st Grade Topic 10 Question • What is frequency? How do you create high frequency? How do you create low frequency?

22. 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).

24. 1,000,000 Question • Explain the difference between pitch and volume. Support your explanation by giving examples!

25. 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! Return
