1. Graphing Activity Raising the Recycling Bar Information Pulled from Provided Reproducible Bwindsor 2013

2. Bar Graph Reasons for Bar Graphs? – Compare Items or Data – Give Examples: 1. 2. 3. 4. 5.

3. Bar Graphs All Bar Graphs Must Have What? – 1. – 2. – 3. – 4. – 5. – 6. Equivalent scale

4. Raising the Recycling Bar Using the website Create a Graph, create a Bar Graph that uses the data below:Create a Graph Type of Waste Millions of Tons of Waste Created Millions of Tons Recovered by Recycling Millions of Tons Sent to Landfill Paper8442 Yard Waste322012 Plastic30228 Metals19712 Glass13310

5. Create a Bar Graph Using a Sheet of Paper, Create a Bar Graph showing the amount of each type of waste created. Think about your scale. – What scale would be good? _______ – Why? _________________________________

6. Thinking about The Data Using what you know about the amount of each material being recycled. Let’s find out what percent of each waste material is being recycled. First, we need to create a fraction. The numerator will be the amount of the waste being recycled. The denominator will be the total amount recycled.

7. What Percent Do We Recycle? Type of Waste Millions of Tons of Waste Created Millions of Tons Recovered by Recycling Millions of Tons Sent to Landfill Paper8442 Yard Waste322012 Plastic30228 Metals19712 Glass13310 Fractional part Recycled 1.Find the fraction parts that are recycled of the whole part created. 2.Simplify the fraction. 3.Come up with the equivalent percentage.

8. Extend Your Thinking! What do you already know about the amount of plastic waste that is created? _____________________________________ How much of the plastic that is created is currently recycled? (In fractional form) _______________________________________ If ¾ OF all plastic waste created was recycled, how many tons of plastic would end up in the landfill?

9. Extend Your Thinking! Plastic Bags are made from OIL! About 12 million barrels of oil are used to make 100 billion plastic bags used in the United States each year. If oil is $65 per barrel, how much is spent to make plastic bags each year?

10. Bonus Calculate the quantity of oil saved if 25% less bags were produced. What do you need to think about or know to understand this question? Break it down!
