Intro: The Color Coordinator
The "Color Coordinator" is an easy tool for teachers or kids to organize their colored pencils, markers and crayons in an environmentally friendly way. It is a cheap and simple way to help the environment by using materials you already have.
Step 1: Step One:Gather Materials
1. 1/2 gallon milks cartons in various colors (however many you choose.)
2. Box cutter.
3. Colored pencils, markers, crayons.
4. Thumb tacks.
Step 2: Step Two
Step 3: Step Three
Place the milk carton face up on a table with the handle to your right. Using the box cutter, cut the width of the carton just under the handle. Cut halfway down the side of the carton and continue down, cutting towards yourself. Then slice halfway through the base of the carton. Continue up until you reach your original cut. Remove the plastic portion you just cut.
Step 4: Step Four
Repeat Step two for each carton you are using.
Step 5: Step Five
Sort art supplies into cartons according to color. These can be any supplies but crayons, markers, and colored pencils work great.
Step 6: Step 6
Add the thumb tacks into the sides of the cartons, one one each carton's side. This is needed to hold them together.
Step 7: Step 7
Enjoy your Color Coordinator!
Step 8: How Is This a Useful Project?
Americans throw away 25,000,000 milk cartons every hour. That's a lot of plastic going to waste. The volume of a 1/2 gallon milk carton is 1/2 gallon, so if 20 teachers at Lahser High School used 5 of these in their classroom, we would be saving 100 1/2 gallons of cartons from being thrown out, thus diminshing the number thrown out hourly to 24,999,900. The number will continue to decrease, the more people use this idea.
# of cartons recycled and used #of people recycling them #amount of milk cartons saved
100 20 24,999,900
200 40 24,999,800
1000 120 24, 999, 000
2000 220 24,998,000
3000 320 24,997,000
Step 9: Eco Friendly
The surface area of a 1/2 gallon milk carton of milk is 324.704 cubic inches. That means that 8,117,600,000 cubic inches of plastic are being thrown out every hour around the world. If entire schools and communities got involved and recycled these milk cartons,here's how much we would save.
Step 10: Mathematical Calculations
Formula for Surface Area of Half Gallon Milk Carton : Length-9.5 in. Width-3.75 in. Radius of cap-0.74 in. Height of cap-0.79 in. Width of handle-1.7 in. Length of handle-2.4in. Width of space between handle and carton-0.76 in. Length of space between handle and carton-2.3 in. Calculations-9.5x3.75=35.625, 35.625x3=320.625, 3.14x0.74x0.74=1.72, 1.72x2.4=4.08, 0.76x2.3=1.748, 4.08-1.748=2.332, 320.625+1.72+2.332= 324.704 inches cubed!
