Question

1. reflect on your data and write a conclusion in the style of cer (claim evidence reasoning). for help with this, look at this handout e.g., which explains each part and gives sentence starters. claim (write the statement that you are making about what you learned from this experiment) the density of a liquid affects the order they will go when different liquids are poured into a graduated cylinder. evidence (write the specific data (i.e. measurements) to support this claim) reasoning (explain in detail how that data supports your claim - connect your evidence back to the claim by describing how those measurements/data supports the claim)

Explanation:

The task is to write a conclusion in the Claim - Evidence - Reasoning (CER) style. The claim is about the effect of liquid density on layering in a graduated cylinder. Evidence should be specific data like measurements of density and layering positions of different liquids. Reasoning should explain how the measured data shows that density determines the layering order, for example, denser liquids sink to the bottom and less - dense ones float on top.

Answer:

Evidence: When we poured water (density = 1 g/cm³), vegetable oil (density = 0.92 g/cm³) and honey (density = 1.42 g/cm³) into a graduated cylinder, honey settled at the bottom, water was in the middle and vegetable oil was on the top.
Reasoning: The data shows that the liquid with the highest density (honey) went to the bottom, the liquid with the intermediate density (water) was in the middle and the liquid with the lowest density (vegetable oil) was on the top. This supports the claim that the density of a liquid affects the order they go when different liquids are poured into a graduated cylinder as denser liquids displace less - dense liquids and settle below them.
