Where have you noticed a problem with waste?

What data could you gather and analyze to learn about the problem?

Identify a local problem related to waste 

You observed a faraway phenomenon in the film about Midway Island. Now it's time to think about a similar phenomenon you could investigate at a nearby location. Waste can take many forms, from leftover food and trash on the ground to junk cars, outdated electronics, disposable containers, forgotten toys, old clothes, piles of tires, and even sewage sludge. What have you noticed at home, at school, or in the neighborhood?

Decide on a type of data to collect 

Check out the boxes below to learn about the protocols scientists use to gather data on waste. Think about which method would provide the most useful and relevant information, based on the local problem you have identified to investigate. CHOOSE ONE WAY to collect data at your location.

Take into account whether you have the supplies and resources needed for that type of data collection. (Look at the Supply Lists to see which methods are feasible to do). Consider selecting a community science project that allows you to contribute data to an authentic research project. Or design your own data collection project. If you are working with a team, be sure to confer with your partners and get teacher approval before starting data collection.

  • Gloves for sorting
  • Labeled trash cans for sorting
  • Clipboard and pen to record results

Garbology Challenge

Collect, weigh, and identify all the waste that you (or your family) produces in a week. Keep track of the leading types and sources of waste. Determine how much of the waste collected could be reused, recycled, or composted. What waste could have been prevented?

Supply List

  • Luggage scale for weighing waste
  • Gloves for handling waste
  • Trash bags
  • Clipboard and pencil; optional camera

Food-printing

The Food-print app allows tracking of leftover single servings of food at participating restaurants, so people can purchase it at a discount, pick it up at a discount price, and save it from the landfill! To find out more about the app and whether it works in your area, click here

Supply List

  • Nitrate testing equipment or reagent
  • Phosphate testing equipment or reagent
  • pH test kit
  • Dissolved Oxygen (DO) testing equipment
  • Turbidity column and chart (or sechi disc)
  • Paper and pencil or app to record results

Note: simple color-changing reagent tests are available in the GREEN Low Cost Water Monitoring Kit included in Captain Planet Foundation's WATER ecoSTEM Kit.

Microplastics in SOIL 

Mark a 1 meter square area, sift soil, lift potential microplastics to filter paper with tweezers, and count (or weigh) the plastics. Use this Microplastics Identification Guide to clarify which objects are plastics. Do not return waste to soil.

 

Supply List

  • Quadrat frame or hoop, 1sm
  • Sifter or collander
  • Magnifier, tweezers, filter paper
  • Microplastics Guide

LITTERATI

What are the most common types of litter in your schoolyard or community? Who makes or sells the products that are being littered? Who does the littering? Collect and categorize litter; contribute your data to real research.

Analyze your data

analytics
  • Display the data in labeled charts or graphs using Excel, Create-A-Graph, or handmade charts
  • Look for trends or patterns
  • Interpret your data by explaining the significance of your findings

Deliverable: Data Collection & Analysis

Organize and show your data in graphs, charts, or infographics to make it easy to analyze and explain the significance of your findings. What does your data mean and why does it matter?

I identified a waste problem and collected data to investigate it.
I displayed my data in a labeled graph or chart and looked for trends or patterns.
I explained the significance of my findings (the "so what?" factor)
