there for a while‚ since the 1960’s-why do some moths produce clicking sounds when bats attack them?” Most tiger moths emit ultrasonic clicking sounds to signal how toxic they are to bats. But Bertholdia trigona emits ten times as much sound‚ “indicating that it might be serving a different purpose entirely”. Aaron and colleagues collected the moths and put them in a cage with brown bats. They hypothesized that if the sounds were used for warning purposes the bats would ignore the clicks and eat

between the fingers of my left hand and a 60kg camouflaged bag on my back‚ I attempted to mentally stop and fight all my instincts which were telling me to run and retreat. The sound of gunfire made me want to turn around and face the noise coming from the other direction. As my aim and torch followed and rose up to the sound‚ it lit a dark alleyway invisible to the naked eye. The gunfire stopped as soon as it started so I took several deep breaths as I panned the small beam of light around the alleyway

When the students were asked on a scale from one to ten‚ (one being that noise does not affect resident’s dorm life

the relationship between the speed of sound in air through the pulse-echo experiment and the measured air temperature. Hypothesis: I believe the measured air temperature will affect the speed of sound because sound waves are longitudinal waves composed of the alternating compressions and rarefactions in air. If the air temperature is below 0°C‚ then the speed of sound would be lower than 331.6 m/s and if the air temperature is above 0°C‚ then the speed of sound would be higher than 331.6 m/s. Materials:

because of all the combinations of all the parts. And how the music flows with the deep voices of the men in that choir. Another reason I like the song is just how all the parts perfectly put it together to show how challenge it sounds to sing this piece. The tone in this song sounds very deep and very dark because there are no high notes for the men. The amounts of dynamics to sing this song were a lot since they have to know your part and not miss a single note.How like the winter is my favorite song

The Sound of Blue Velvet In Dreams You’re Mine Forever….is this Frank’s line‚ or is David Lynch speaking to the audience? Blue Velvet opens surrealistically with a dream-like/nightmarish introduction to suburbia. Amid the red roses posed against the white picket fence framed by the blue sky dwells a world of voyeurism‚ sadomasochism‚ the American dream‚ and naiveté. Lynch takes no time in getting to the dichotomizing nature of the film. Within the first few minutes‚ the viewer is shown

This encourages children to listen‚ sing and communicate‚ this can be through using their hands to start off with and eventually hands and singing. Musical instruments can be good for the children to practice repeating different sounds that are made or making the sounds louder or quieter. Blowing bubbles; this activity is good to enable the child to point to different things that the bubbles are hitting‚ they show interest and can start by making simple words such as “gone” when the bubble has burst

Abstract This study was conducted to determine the combined effects of coloured lighting and ambient sound on mood. 48 psychology undergraduates‚ comprising of 38 females and ten males‚ took part in this study. This study is a 2x2 between subjects design. The coloured lightings used in this study are blue and yellow combined with the ambient sound of ‘city’ and ‘nature’ whereas mood was measured with the Positive and Negative Affect Schedule (PANAS). We discovered that coloured lighting had no significant
