The Bean Lab

Exploration Objectives

• What is a 'pot' of beans? A 'pot' of beans is the relative mass of each different bean.  
• Why is relative mass used to determine the number of beans in a pot? Relative mass is used to determine the number of beans in a pot because the relative mass is used to create a ratio. We used the lightest bean to create a ratio for all the beans.
• Why is this 'pot' a model for the mole? This 'pot' is a model for the mole because its a constant number.
• What relative mass is used for the mole?  Why? Carbon-12 is what's used for the mole because, the mass is 12 with 6 protons, which makes it an even ratio because it also has 6 electrons.
