Graphing Activity

This graphing activity focuses on raising awareness about recycling by analyzing waste data. Students will learn the purpose of bar graphs, which include comparing items or data and identifying common features of effective graphs. They will create a bar graph representing the types of waste generated and recycled materials using provided data. Additionally, students will calculate the percentage of waste recycled and explore the impact of plastic waste on the environment. This hands-on activity fosters critical thinking about recycling and environmental conservation.

  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:

  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? Find the fraction parts that are recycled of the whole part created. Simplify the fraction. 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!
