An elementary student decides to conduct an experiment comparing the effectiveness of two commercial soaps as cleaning agents ("soap 1 and soap 2"), using each in paired tests of different types of stains and colors of cloth, where the only variable is the soap used. the student will use the judgment of classmates to decide if the stains remain equal or if soap 1 cleans better than soap 2. however, the elementary student made no prediction of which soap is expected to perform best.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
