# 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:

• Pipette with a safety bulb
• Beaker
• Water
• Electronic Balance

### Experimental Procedure:

1. Weigh the graduated cylinder with the electronic balance and record the weight on the table.
2. Put 100g of water in the graduated cylinder and then weigh the cylinder with care so that the water does not spill.
3. Calculate the difference between the weight with the water and the weight without the water.
4. Repeat steps 1-3 again 2 more times.
5. Repeat steps 1-4 with your pipette (10g) and beaker (100g) and record your observations.
