The adventures of a fourth grade teacher in East Central Illinois.

Acoustical Engineering

Miss C and I recently started an incredibly awesome project with our Learning Buddies. They are doing a science unit on acoustical engineering, using resources recently acquired by our instructional coach. For the next several weeks, they will be exploring problems related to sound and using the engineering process to learn about the problem, imagine a solution, develop a plan, create a solution, and improve it after testing it out.

We started last week with a pre-assessment by asking the first and fourth graders to tell us what sound is and then to think about a way to communicate a song. This week we both read a story to our classes called Kwame’s Sound about a boy in Ghana who is going to be playing the drum for an Odwira with his cousin Kofi and has to figure out how to share the rhythm he came up with. The challenge is that Kwame is blind and so he can’t use traditional written music. He uses his knowledge of the engineering design process that his acoustical engineer father has taught him.

When the students were together this afternoon, we had the students identify the elements of the engineering design process and then had them work on an assignment coming up with different words (onomatopoeias) to describe the sounds made by drums, elephants, birds, cell phones, and other things. One thing we discovered pretty quickly is that it is really, really, really difficult to come up with words that represent the sound an elephant makes. We have words to describe how the sounds is made, such as trumpeting, but we don’t have a true word for it. As a result, it was a lot of fun seeing what our students came up with!

I am really excited about this project and can hardly wait to see what our students will do next as they learn about acoustical engineering and actually put it into practice! If you had asked me even a month ago if I thought children under the age of 10 could even say the word “acoustical,” let alone use it correctly, I would have laughed! Now, though, I know better! We have a group of nearly 40 students who can define acoustical engineering, describe what acoustical engineers do, and explain the engineering design process!

Oh, and my class also knows what fufu is. Two of my students have even eaten it regularly. I may see if I can get one of their parents to make some to share with the class.
