Compressed Zip File

Fun and simple to make. Sounds just like a Cicada, Cicale or Semi as they are known in Japan. The real insects make noise up to 120 db, yet my 4-6 year olds seemed louder !
The sound is made from the vibrations of the rubber bands between the two large wooded popsicle sticks, like air passing over your vocal chords.
Children aged 4 and up can independently make this craft.
The instructions are straightforward and clear, in easily identifiable steps, and illustrated with colour photos. This is one of those rare activities that suits all ages. A number of teachers from my school even dropped in to make one for fun. Ideal as a gift for hard to please nephews and nieces !
I focused on having fun making an instrument with younger classes, but with older students you can begin to focus on how sound waves work.
You will need the following per student
• 3 page set of instructions, (stapled together to keep them in sequence)
• 2 Large lollipop sticks
• 2 Small rubber bands
• 1 Large rubber band
• 1 Straw
• 1 Pen
• 1 Pair of scissors
More than a fun time filler !
• Physics - Oscillation, Vibration, Compression Wave
• Music - Musical Instrument, Frequency (pitch)
From experience I’d recommend checking in advance that the class next door has not scheduled a quiet reading or writing session
This craft works really well on open science days, science fairs, first / last week of term and so on. I've had parents and indeed other teachers drop by my classes to make these as my students do.
