Question

question: the density of water is 1.0 g/ml, which is equivalent to 1 g/cm³. how does an objects density affect whether it sinks or floats in water? 1 form hypothesis how do you think an objects density relates to whether it sinks or floats? 2 collect data measure the mass and volume of each known material, and calculate its density then drag each material into the water to see whether it sinks or floats material mass volume density sinks or floats? polystyrene aluminum wood stone 3 analyze how does an objects density determine if it will sink or float? 4 apply find the density of unknown a and unknown b based on their densities, predict whether each will sink or float then test your prediction using the gizmo material mass volume density sinks or floats? (prediction) sinks or floats? (actual) unknown a unknown b 5 extend your thinking compare the three floating materials how does the density of each material relate to how high it floats in the water?

Explanation:

If an object's density is less than the density of water (1.0 g/mL or 1 g/cm³), it will float. If its density is greater than that of water, it will sink. For floating objects, the lower the density compared to water, the higher it will float in the water.

Answer:

1. Hypothesis: If an object's density is less than water's density, it will float; if greater, it will sink.
2. (No data provided to fill the table, but the density formula is $

ho=\frac{m}{V}$, where $
ho$ is density, $m$ is mass and $V$ is volume. Then compare density with water's density to determine sink - or - float.)

1. An object's density determines its sink - or - float behavior based on comparison with water's density. If $

ho_{object}<
ho_{water}$, it floats; if $
ho_{object}>
ho_{water}$, it sinks.

1. (No data for Unknown A and B to calculate density, predict and test. But follow the same density - comparison method as above.)
2. For floating materials, the lower the density relative to water, the higher they float in the water.
