How does temperature affect viscosity? NOTE if you actually have more than one hour, then also learn about how viscosity affects very small organisms like phytoplankton and fish larvae and think about how global climate changes could impact the viscosity of the oceans and what that might mean for marine ecosystems.

Audio Speech Melodies Human speech is made up of vowels a, e, i, o, u and consonants b, c, d, f, g, etc. Consonants are typically noise-like pops, bursts of air, etc. Vowel sounds are tone-like: These pitches are produced by rapid vibrations of the vocal cord. For adult males, the fundamental frequency of voiced speech is typically in the 85 to Hz range; for adult females, it may range from to Hz.

Singing may cover a wider range. When people speak, different syllables usually have different pitches. As with breathing, these pitch changes are generally made unconsciously.

There are gender differences in vocal pitch aside from Science fair 2011 12 frequency ranges involved. Generally speaking, males tend to speak in a somewhat more monotonic way, while women tend to make more expressive use of pitch. Some women have very melodious voices. If we think of speech as having a melody, it's almost as if they're writing a song, with melody and lyrics, each time they speak.

For example, I noticed this when listening to dialogue by the mother in the movie "As Good as It Gets", and when listening to a recording called " Radical Acceptance: Guided Meditations " by Tara Brach. In the latter recording, it seemed as if the speaker had a mental musical scale; one particular tone seemed to serve as the root or home base, with frequent excursions emphasizing the musical intervals of a fourth frequency ratio of 4: Are these music-like intervals chosen because they're easier to make, more pleasant to listen to, or do they have some kind of perhaps hard-to-define meaning?

So the basic question is, why do we use pitch modulation when we speak? Does it help transfer the information we're trying to convey? Does it help transfer emotional information? If someone speaks with a very monotonic voice few pitch changeswe may think of their speech as "monotonous", which can mean either lacking in pitch variation, or lacking in variety and interest, i.

Could one design an experiment to tell whether information content is transferred more effectively with monotonic robotic voice, normal voice, exaggerated pitch changes, or random pitch changes? How do these types of pitch contours affect how the listener thinks of the speaker?

Do they make the speaker seem more sincere or likeable? Do they make the content more or less believable? Why did human speech evolve to use these pitch changes? Note that some languages, such as Chinese and Vietnamese, are "tonal", in which the same word can have different meanings depending on the pitch.

In western languages, pitch changes can emphasize certain words. Often if we repeat similar or parallel phrases, we may repeat the same pitch contour, using the pitch to highlight the similarity between the concepts.

In what other ways are pitch changes used? Does the amount of pitch modulation correlate to personality, or to psychological conditions such as depression? In songwriting, melodies are often chosen for their attractiveness, but they also need to fit the meaning of the phrase, in ways that may be difficult to define or analyze.

As a simple example, a songwriter is more likely to go up in pitch when singing the word "up", and lower in pitch for the word "down".Follow @SEFMD To request a school packet of information, click here To register for the EMA/SEFMD event at the Detroit Public Library on SATURDAY, Nov 17 - click here Tony Pan of University Liggett wins Weizmann Institute of Science Award.

A useful teaching resource for teachers. Following are some weird, strange, cool, uncool, fun, funny, bizarre, unusual, or just slightly different ideas for science fair projects. Most of these are very half-baked, so you would need to figure out how to develop a testable hypothesis and .

Open science is the movement to make scientific research, data, and dissemination accessible to all levels of an inquiring society, amateur or professional. Open science is transparent and accessible knowledge that is shared and developed through collaborative networks. It encompasses practices such as publishing open research, campaigning for open access, encouraging scientists to practice.
