Question

1. predict: in the table below, write the density of each object. then predict whether the object will float or sink in each of the fluids. write float or sink in each empty box of the table.

object object density
1 0.5 g/ml
liquid density 1.0 g/ml
2.0 g/ml

1. test: test your predictions using the gizmo. place a checkmark (✓) next to each correct prediction, and an x next to each incorrect prediction.
2. draw conclusions: what is the relationship between the object density, the liquid density, and the tendency of the object to float?

Explanation:

Step1: Recall density - floating rule

If object density < liquid density, object floats; if object density > liquid density, object sinks.

Step2: Predict for liquid density 1.0 g/mL

Object density is 0.5 g/mL. Since 0.5 g/mL < 1.0 g/mL, it will float.

Step3: Predict for liquid density 2.0 g/mL

Object density is 0.5 g/mL. Since 0.5 g/mL < 2.0 g/mL, it will float.

Answer:

For liquid density 1.0 g/mL: Float
For liquid density 2.0 g/mL: Float
