James is given four liquid samples. One sample contains living things, but the other three do not. Each sample appears cloudy, but James cannot see with his unaided eyes what the material is in each sample. He is asked to identify each sample as containing either living or nonliving things.

James would need to observe the samples through a microscope. He would need to see if he could observe cells within the sample.
James would calculate the chemical energy of each sample. He would then analyze the data to determine which samples have the most chemical energy.
James would count the number of things they see in each sample. He would use this to see if there are more things in one sample over another.
