A Student Fills Two Beakers With Equal Amounts Of Soil And Adds Germinating Bean Seeds

A student fills two beakers with equal amounts of soil and adds germinating bean seeds in Beaker 1 and glass beads in Beaker 2. The student seals both beakers with thick plastic sheets, inserts a straw and thermometer through the sheets, and places both beakers on a table at room temperature.
