Maggie is a member of her school’s environmental club and is interested in recycling. she asks the question, “how does exposure to the environment affect recyclable plastics? ”
what best describes why and how maggie should change her question to make it a better scientific question?

Plastics are marked as the most important factor in degrading of environment about three to five hundred years to decompose completely hence the more production of plastic the more is the adverse effect on the environment. Using recyclables plastic can decrease the production of plastic on daily basis thereby  decreasing certain quantity of plastic that is present in the environment.

Hence maggie’s question should be reconstructed to form a scientific question in this way. How can using recyclable plastic reduce its exposure in environment?
