  1. Lab Equipment

  2. Appropriate Apparatuses for Biology Investigations • Balances, triple beam or electronic • Beakers (50mL, 100 mL, 250mL) • Burners (Bunsen) flint strikers • Erlenmeyer flask • Evaporating dishes

  3. Appropriate Apparatuses for Biology Investigations • Filter paper • Forceps • Funnels • Graduated cylinders (10 mL & 100 mL) • Hand lenses (magnifiers) • Hot plates • Measuring tools (rulers, meter stick, meter tapes, stop watch or timer) • Microscopes (compound & dissecting) • Microscope slides & cover slips, light source, lens paper

  4. Appropriate Apparatuses for Biology Investigations continued • Lab aprons, safety goggles, gloves • Measuring tools: clear metric rulers, meter sticks, and meter tapes; stop watch or timer • pH indicator paper, pH buffer solution • Prepared slides of normal cells, cancerous cells, human cheek cells, onion root cells, bacteria, protists, fungi, sickle cell blood, chromosome smear, whitefish blastula, etc.

  5. Appropriate Apparatuses for Biology Investigations continued • Pipettes / droppers • Petri dishes • Ring stand, ring clamp, and test tube clamp • Stirring rods, spatulas, scissors, chemical scoop • Stoppers – rubber, cork • Test tubes, clamp, holder, and rack • Test tube brushes • Thermometers (alcohol, digital) • Tongs (crucible, beaker)

  6. Appropriate Apparatuses for Biology Investigations continued • Watch glasses, spot plate • Wire gauze with ceramic centers • Wood splints

  7. Precision and Accuracy • Precisionis a measure of the degree to which measurements made in the same way agree with one another. • The accuracy of a result is the degree to which the experimental value agrees with the true or accepted value. • It is possible to have a high degree of precision with poor accuracy. This occurs if the same error is involved in repeated trials of the experiment.
