Petroleum-based Polymers vs. Plant-based Polymers A petroleum-based (inorganic) polymer is commonly used for grocery bags. Recently there has been a push by environmentalists to make grocery bags out of plant-based (organic) polymers.
Students in a science class decided to investigate the strength of the two types of polymers. They obtained one petroleum-based (inorganic) polymer bag and one plant- based (organic) polymer bag of the same size and thickness. They added 100-gram weights to each bag until it broke.
The students found that the plant-based polymer grocery bag held 500 grams before breaking and the petroleum-based polymer grocery bag held 600 grams before breaking. In order to increase confidence in their results, the students should repeat the investigation using _____________.
