When a golf ball is dropped into a tray of wet sand, it sinks into the sand and leavesan indentation. the table shows the depth of indentation in the sand when the samegolf ball was dropped from various heights.

golf ball experiment results
height of dropped ball depth of indentation in sand
0.5 meter. 0.2 centimeter 1.0 meter
0.5 centimeter 1.5 meters. 0.9 centimeter. 2.0 meters. 1.6 centimeters

which of these is the best explanation for the recorded results?

a. the kinetic energy of the ball increased as the speed of its fall increased.
b. the ball began to accelerate after it had fallen about 1 meter from where itwas dropped.
c. the amount of moisture in the sand decreased due to evaporation duringthe experiment.
d. the ball moved a random amount of sand each time it hit, causing thedepth of the indentation to vary.

For a family dinner, jose’s mom baked a loaf of bread. during the meal, his grandmother commented, “this bread is so dense! ” what do you think his grandmother meant by the word dense? you have some ideas regarding density already, but this experiment will enrich your understanding of the relationship between mass, volume and the density of objects. when making measurements in this experiment we will be using si units, the international system of units. the purpose of using si units is to have the ability to communicate and compare data results with other experiments without having to make conversions. measurement symbol si unit length m meter mass kg kilogram volume l liters density kg/l kilograms per liter any calculations that are performed during this experiment will ultimately be reported in scientific notation. recall that scientific notation is extremely important when we have data that is extremely small or large. scientists rely on a standard form of communication to quickly make hypotheses and judgements based on data. what is the density of block a? a0kg/l what is the density of block b? a1kg/l what is the density of block c? a2kg/l what is the density of block d? a3kg/l what is the density of block e? a4kg/l which block is the densest? a5
