Living Environment
New York State Core Curriculum 
Laboratory Checklist

In addition to demonstrating the performance indicators relating to scientific inquiry described in Standard 1, biology students need to develop proficiency in certain laboratory or technical skills in order to successfully conduct investigations in biological science. During the school year, teachers should ensure that students develop the capacity to successfully perform each of the laboratory skills listed below. Proficiency in performing these laboratory skills may also be evaluated by items found on certain parts of the State Living Environment assessment.

• Selects and uses correct instruments
  

• Uses graduated cylinders to measure volume
  

• Uses metric ruler to measure length
  

• Uses thermometer to measure temperature
  

• Uses triple-beam or electronic balance to measure mass
  

• Uses a compound microscope/stereoscope effectively to see specimens clearly, using different magnifications
  

• Identifies and compares parts of a variety of cells
  

• Compares relative sizes of cells and organelles
  

• Prepares wet-mount slides and uses appropriate staining techniques
  

• Designs and uses dichotomous keys to identify specimens
