First we discussed what decibels measure (they are a way to measure the loudness or amplitude of the sound waves). Next we researched decibels using a variety of websites: <a href=\"https:\/\/bouncyballs.org\/\">Bouncy Balls<\/a>, <a href=\"http:\/\/www.dangerousdecibels.org\/exhibit\/virtual-exhibit\/\">Dangerous Decibels<\/a>, and the <a href=\"http:\/\/www.nidcd.nih.gov\/health\/education\/decibel\/pages\/decibel.aspx\">Interactive Sound Ruler<\/a>. That last website has a valuable scale giving examples of sounds at different decibel levels. We used it to calculate the percentage of our day we spend at each level.  I posted a Google spreadsheet template on Google classroom for the students to use. I made some changes to the template after teaching this lesson to simplify things. You can make a copy of the template <a href=\"https:\/\/docs.google.com\/spreadsheets\/d\/1SeOCIUBrLAKPC51MuWaaRAETwsw3fNm6hRXEB-GVdro\/edit#gid=0\">here<\/a>. It has some samples for you to look at in the tabs (sheets) at the bottom. Once we figured out how many hours we spend at each decibel level, we wrote a formula to convert it into a percentage. This is where we used fractions because the formula was a fraction with a variable in the numerator (# of hours)\/24 hours.  Next we highlighted all the percentages and created a pie chart. When the students posted their spreadsheets to Google classroom they estimated the fraction of their day spent at a certain level.
