Astronomy is one of the mathematical sciences. Her perfect instruments are unique. “Whosoever believes that anybody can execute measurements on order and without previous practice, and that each measuring instrument delivers correct results, is in error. Whosoever wishes to achieve this must, first of all, spend a long time on the study of the instruments and on the practice in measuring, until finally his measurement rests on the knowledge of the precision of his instrument and on his experience in measuring.” Ibn Yūnus (d. 399/1009) "The whole universe obeys a strict order, howsoever variable its affairs might be, and there is harmony between all its parts, howsoever different they happen to be." Ibn al-Haitam (d. 432/1041)
An anemometer is a weather instrument. An anemometer measures the speed of the wind. If you are working on a weather unit with the kids you might want to make one of these cool paper cup anemometers. Materials safety goggles 2 straws 5 small (bathroom) paper cups paper punch small stapler or tape pencil with eraser push pin recycled plastic container with lid (frosting, yogurt, etc.) heavy weight to put in container (rocks/ pebbles/sand/clay) Directions (Adult Supervision Required) All participants should wear safety goggles. Use a paper punch and in 4 of the cups punch a hole about a centimeter down from the rim. In the 5th cup punch 4 evenly spaced holes about a centimeter down from the rim and also make a small hole in the bottom center of this cup. Make a small hole in the center of the rim of the plastic container Push a pencil through the center hole of the cup and also through the plastic cover of the container which will be the base of the anemometer. If desired, add some weight (sand, rocks, etc.) into the container so the wind will not knock over the anemometer. Slide one of the straws through the hole in one of the 4 cups that has only one hole in it. Bend the end of the straw that is inside the cup and tape or staple it to the inside of the cup. Place the other end of the straw through two of the holes in the 5th cup. Then through the hole in one of the other cups.Also tape or staple the end of the straw to the inside of the cup. Repeat the last 2 steps with the remaining 2 cups. Make sure the 4 cups all have their open ends facing in the same direction (clockwise) around the center cup and pencil. Push the push pin through the two straws where they overlap and then into the pencil eraser. Mark one of the cups with a marker! Use that cup as your starting point when measuring wind speed. When the wind blows count how many times the marked cup goes by in one minute. You may want to measure (count) and record the wind speed 2 or 3 times per day. You could compare morning and afternoon wind speeds. Is the wind stronger in the morning or afternoon? Compare different days. Make a graph with your data. ~ To view directions for making a protractor anemometer click here. Have fun learning about weather.

Offered is a vintage 10 Note Tongue Drum percussion set, including the hand carved tropical hardwood box drum, a pair of mallets, and a set of Claves percussion sticks, both instruments by renowned instrument house Latin Percussion. While the drum is perfectly functioning, tuned to play 10 musical notes, these are often purchased as decorative objects by collectors. We've included wood mallets, but this piece would probably work best with rubber headed drum sticks or lollipop mallets. We've tested this piece with a professional percussionist and have been assured that the notes are perfectly tuned. Drum measures 17.5" long, 5.5". wide, 4.5" deep Clave percussion sticks measure 9.5" long, 1.25" diameter Mallets measure 12" long, 1" diameter History of Latin Percussion company: In 1956, Martin Cohen, a young mechanical engineer and avid photographer from the Bronx happened upon New York’s famous Birdland jazz club. He walked in and was immediately captivated by the sound and energy of Latin jazz. 1956 Martin Cohen was so taken with the infectious music that he immersed himself in the 1960’s Latin music scene and soon wanted his own set of bongos. Unfortunately, due to trade embargoes, high quality, Cuban-made bongos were unavailable in the United States. So Cohen put his engineering skills to use and created his own set of bongos. After months of study, Martin Cohen had successfully built what would eventually be heralded as, “the finest bongos the world had ever seen.” 1960 In 1964, Martin Cohen founded Latin Percussion (LP) and was soon delivering bongos, cowbells and other instruments in brown paper bags to musicians. Cohen utilized New York’s Latin nightclubs as his research and development labs – utilizing artist’s real world experience playing live music to craft and hone the best possible percussion instruments for live and recorded performance. Cohen’s self-described “love affair” with Latin music established a tradition still practiced at LP; the needs of performing musicians are placed ahead of everything else. less
