PDF Version: Carbon Footprint @ TPT

The Product: Students complete an Amazing Race style challenge where they must finish a cross country trip and select choices that are within their carbon footprint, financial and time budgets!

Hey kid, all administrators drive Hummers.
It's required! No, I don't know about its
carbon footprint! Oh, really?!

While you may not raise sufficient capital to put a fleet of windmills in your school parking lot, you can still teaching some environmentally conscious mathematics! 

In the 2000s, the Kyoto Protocol aimed to set goals for an individuals carbon emissions by country. The United States decided this wasn't something they wanted to be part of. When doing some inequality mathematics, you can quickly see how challenging this would be for an average, I like to drive my own car 30 miles a day and eat a hamburger for dinner type of person. Although students may not make an drastic life changes (maybe they will) it will at least be an assignment that ensures they at least see a link!

Although students will learn elements of carbon emissions, the lessons focus on creating and using multi-step inequalities to model situations and make decisions. With an increasing focus on environmental issues this explores a view on a science topic that students may never have been exposed to before.

You mean like I have a theoretical
footprint because I eat Hot Cheetos?

-- Planes, Trains & Automobiles.  Students will write multistep inequalities to determine if individual’s daily transportation needs exceeds the CO2 emissions totals described in the Kyoto Protocol.

--  Well-Traveled Food. Students will use the Food Footprint Chart to complete this assignment which provides a look at food production and transportation emissions and the difference between local and traditional food sources.

which leads to the project --

-- the Amazing [more environmentally conscious] Race. Using a CO2 Emissions Per Activity chart, student will make travel and food choices on a cross country trip.

This is all great and everything,
but what could be do to take action
in our local community?

It doesn't take much looking to find this issue in the news in one shape or form and kids like travel and food maybe it's a great match for you!

EXTENSION: Student could certainly track their own Footprint over a 24 hour period. Other ideas could be things like a recycling club, a push for automated light switches, a student presentation to the school. 

This 21st Century Math Project is endorsed by Polar Bears everywhere! Well that's an exaggeration, I've only asked the two at our zoo and I'm not sure if that's exactly a representative random sample since they were born in captivity.

The Underground -- International STEM Project

Mind the Gap. Mind it Well.

Expand your student's international education with an exploration of the London Underground in this 21st Century Math Project. Through building skills of estimation, measurement, and use of scale, students will conclude their learning with an estimation of London's Circle Line. This is a hands-on STEM Project for hands-on learners and provides a nice departure from the grind of the daily classroom.

Name: The Underground

Suggested Grade Level: 7-12 (Algebra & Geometry skills)

Math Concepts: Measurement, Scale, Proportion, Distance and Estimation

Interdisciplinary Connections: Travel, Global Studies

Teaching Duration: 3-5 Days (can be modified)

Cost: $5 for a 14 Page PDF (1 project, 1 assignment and answer key)

What's a ruler?

The Product: Students develop a strategy to approximate the length of a train line on England’s famous Tube and use their approximation to find the distance between the tube stops of tourist destinations.

Whenever our math department gets disaggregated data back on standardized tests there always one consistency that we can count on – students are low in measurement. Usually they are really, really bad. It’s as if they have no concept of an inch or never touched a protractor. When the word scale is thrown in the mix – it’s every math teacher for themselves. Anarchy.

My idea behind this project was to make a creative task that would be both mathematically rigorous, but interesting. In this project, students will have to measure, use a scale, calculate proportions to estimate distances… all in a seemingly sensible way. This packs in about as many problem spots into one project as humanly possible. Buckle your chin strap and dive right in.

Haha. Gotcha. Proportion and
measurement are elementary skills!

I learned something interesting in developing this project. The Great Wall of China is in fact spread apart in many different pieces. Miles apart. I always thought it was one long wall. Uh… hey what am I talking about? Too much cough syrup? When I originally conceived this idea I planned to approximate the length of the Great Wall. When I discovered this would be nearly impossible I went for something a little more achievable. With all the math packed in, I couldn’t bear to complicate the project by estimating multiple pieces of the Great Wall.

Truth be told, the necessary level of these separate math skills (measurement, scale, proportion, distance and estimation) vary great. In the Common Core, some of these skills are listed in 5^th grade, others in 8^th grade. However as a high school teacher, these are areas of significant skills deficiency. Students can cross multiply and divide, but they have difficulty recognizing a proportion problem and have trouble setting it up. Certainly, the higher order thinking skills necessary in this project raise the level of difficulty.

Calculus? I could get used to that...

Depending on your state tests, this could be a useful prep assignment. If you are working with remedial students, it’s a more concrete assignment to help work on past skills, while pushing forward their thinking skills. Usually when I teach high school geometry, I like to slip this in after I want to review Perimeter. Perimeter is an elementary skills, but non-linear perimeter? We’re talking about Pre-Calculus and Calculus.

EXTENSION: This can get a little tricky, but an idea that I have to extend this is that you can have students find a picture from the internet of a non-geometric shape. After determining a scale, they could do the same activity. It's tricky, but maybe you could pull it off. 

However, or whenever you decide to try this 21st Century Math Project, have a jolly good time and Mind the Gaps.
