Make an observation/formulate a question: The Smithfield City landfill was almost full and so to cut down on garbage the city council decided to give residents compost bins for their food scraps.If the residents have compost bins, the city council wondered if there would be less garbage going to the landfill., Collect information / research: Maya found that the bins with worms had less undecomposed food left, so she concluded that worms helped decompose the food scraps faster.The city council gathered information on how many pounds of garbage arrived at the landfill each week., Form a hypothesis: One city council member, Maya, knew that worms help decomposition, so she thought the food would decompose faster if they added worms to the bins., Conduct an experiment: She set up 20 different compost bins, half with worms and half without, and then measured the percentage of food left in each bin after one month., Present the findings/results: Maya found that the bins with worms had less undecomposed food left, so she concluded that worms helped decompose the food scraps faster.,
