"found percussion"

    Goals and standards

  • Goals - Students will make musical instruments, with a variety of pitches, from found objects.
  • Objectives - Students will bring from home a variety of discarded objects that make interesting sounds when struck. The students will sort the found objects by type and use them, alone or in groups, to assemble collections of similar objects (or similar-sounding objects) with different sizes, that can be used to play three- pitch percussion parts. Each student or group will demonstrate their finished percussion instrument to the class and/or use it in the following activities.
  • Grade Level - K-12 (adaptable)
  • Student Prerequisites - none
  • Teacher Expertise - Teacher expertise in music is not necessary to present this activity.
  • Time Requirements - One (approximately 45-minute) class period.
  • Evaluation - Evaluate neatness, cooperation, and visual presentation, according to your usual rubric for craft activities, as well as student success in constructing an "instrument" with three similar sounds of different pitch.
  • Music Standards Addressed - National Standards for Music Education standard 9 (understanding music in relation to history and culture).
  • Other Subjects Addressed - The activity also addresses National Council for the Social Studies standard 1 (culture).
  • Extensions - Older, gifted, or ambitious students may want to design and make instruments tuned to make specific pitches (more like an actual steel drum, mbira, or xylophone), that could be used to play a melody, from found objects. Encourage them to find objects that ring with clear, definite pitches (nails, rake tines, bamboo sticks, blocks of hard wood, metal bowls, and heavy cardboard tubes are some possibilities), and help them research easy ways to tune the objects.

    Materials and preparation

  • Plan ahead to give your students plenty of time to find and bring in "found" objects that they can use to make instruments. Suggest that they look for discardable objects that have a nice or interesting sound. Send home notes of explanation if necessary. Possible suggestions (depending on how much and what type of work you will want them doing in class): clean, empty metal cans of all sizes, with no sharp edges; clean, empty plastic tubs and lids of all sizes; pieces of bamboo or dowels, cut (at home by a parent) into various short lengths; small pieces of hardwood lumber; empty cardboard tubes from paper towel and wrapping paper rolls, or sturdy cardboard containers such as oatmeal boxes. You may find further ideas in Percussion Fast and Cheap or Sound and Music .
  • You may want to have calypso music to play in the background as they are working on their instruments.
  • Be prepared for a noisy activity.
  • Optional: If a messy activity is OK, you may want to supply, or have the students supply: some dry beans or beads for maraca-type sounds; sticky clay, plaster, water, or sand to "tune" the objects, and/or art supplies to decorate the instruments.
  • You may also want to supply string and/or strong scissors and tape.
  • The students will need beaters or drumsticks to play the instruments with. Rulers, heavy pencils, wooden spoons, real drumsticks, short dowels, or pieces of bamboo are all possibilities. You can supply these, have the students supply them, or use whatever happens to be at hand.

Questions & Answers

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
ninjadapaul
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?

or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

Stotaw
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
