Conserving Water Means Boring Math

Oh my goodness.  The cherubs discovered that trying to determine water conservation requires detailed data collection and transposing water useage into gallons used, converting that number into a decimal and ultimately a percentage.  To make matters worse, I had them take the data and convert it into a bar graph.

so, why the big deal about water conservation?  the story of Mono Lake, tomorrow, will show 'em.

Have a great night, folks.

We "learn" them about math, just not how to use it.  Well, I am teaching them the practical side of mathematics, while teaching them about water conservation.

First, they did a two-day water usage survey with their family. Each time they brushed teeth, washed hands, flushed the toilet, took a 10-minute shower, laundry, etc., they recorded the event with a checkmark.  We then equated each event with average amount of water used; such as .25 gallons of water to wash hands, one gallon to brush teeth, five-gallons per toilet flush, 30-gallons per 10-minute shower.

Students added up all the water used for the survey and tallied the amounts to somewhere around 200-gallons per person for the weekend.

We then used that tally to breakdown the percentage of water used for each activity.

Today, homework was to take either percentages or gallons used to create a bar graph.

Needless to, a lotta kids came in during lunch or planning to visit after school, for help.

I will check my email, often, tonight.

Have a great night, folks.

Most Americans Use About 200-gallons-day Of Water.

Did your cherub?  Does your family?  That's what we calculated, today, as part of an ongoing project "Taking Account of Water."  I was punched as pleased to learn our Loyalsock family conserves water in our homes.  Tomorrow, we will take that data and turn it into a bar graph.

Got an afterschool meeting, today.

Have a great night, folks.
