Oct. 9, 2019 % of Ideal

Objective: To compare experimental value to ideal values.

Entrance task:

• 1. Please take Vocabulary Quiz on Quizlet (Must score 70% or higher).

• Show Porth.

Lessons:

2. Finish Lab: Density by displacement

• Make sure you used an equation to calculate your Densities.

• Google the densities of each item and report on your spreadsheet in another column.

• Use this equation to calculate the % of ideal: your value/ideal value x 100 (formula is "=e2/f2x100")

• Question: How close are my experimental values to ideal values?

• Hypothesis: The % shows that I was able to experimentally get close to the ideal value (i.e., steel bolt is the same density as steel bar).
