Variables
The independent multivariate for this experiment was beans. The dependent variable, that depends on the independent to change, was the mass per bean. The deem does not change and this experiment it was the amount of beans (60).
Purpose
The purpose of this research laboratory experiment was to lean about the average mass and the relative mass using different events of beans for representations. The safety precautions for this lab was to suffer goggles while in the laboratory and to wash pass on after the lab.
Materials
safety goggles
laboratory apron
graduate cylinder 100-mL
4 beakers, 150-mL
wax marking pencil
funnel
navy beans
kidney beans
pinto bean
capital of Peru beans
4 typography transfuses
laboratory balance
Procedure
1.

Put on your goggles
Take a marking pencil label each beaker one grapheme of bean: navy, kidney, pinto, lima
obtain a sample of each type of bean and take sticker to station
Using a graduated cylinder pour 17-20-mL of navy beans
pour 55-60-mL of kidney beans into the cylinder and then into proper beaker
Pour 35-40-mL of pinto beans into the cylinder, then into proper beaker
Pour 110-115-mL of lima beans into the cylinder, then into proper beaker
Label each of the four account cups with the name of one bean
bankers bill the mass of each cup and record the value in the selective information Table
count 60 beans of each variety and place them in the proper cups
Measure the mass of the cup with the beans and record the values in the Data Table
Return each type of bean back into its original container
Clean work area and wash hands
14. fix calculations to find the mass of the beans(g), the average mass per bean(g), and relative mass of the beans(g)
