The Science of Human Error
Objective:
In this experiment, you will find out how human error can cause faults in any science task. This includes experiments conducted by famous scientists also.
Research Questions:
- Is it possible to perform each calculation of data precisely to get an exact answer?
- If you need 50g of water, is it possible to pour 50g of water all the time? Explain.
- If you round an answer during a calculation, does it change your answer considerably? Why or why not?
Materials:
- Graduated Cylinder
- Pipette with a safety bulb
- Beaker
- Water
- Electronic Balance
Experimental Procedure:
- Weigh the graduated cylinder with the electronic balance and record the weight on the table.
- Put 100g of water in the graduated cylinder and then weigh the cylinder with care so that the water does not spill.
- Calculate the difference between the weight with the water and the weight without the water.
- Repeat steps 1-3 again 2 more times.
- Repeat steps 1-4 with your pipette (10g) and beaker (100g) and record your observations.
