Determine the density of three pure solids on g/cm3. Choose objects of which you are sure of their identity, such as
aluminum foil (crumpled or in a ball), copper wire or iron nails. Then, test an object that you think might contain one of
the materials you tested.
Report as to whether your data supports your hypothesis. Write a 200 word report including hypothesis, procedure,
results, and conclusions. Discuss the question, "What factors cause differences in density?" Be specific.
Example: If you choose aluminum foil and test its density by doing a water displacement test. You could then choose a
soda can or a can that contained some fruit, vegetable, or soup and test the can.
Example: If you choose to test copper wire, you could use a penny for your second test to see if the penny is pure
copper.

Hannah is writing a report on how albedo affects the global climate. she’s proofreading her passage for any factual errors. which sentence must hannah correct before submitting her report? earth receives energy from the sun. this energy drives many of the processes on earth, including its climate. some part of this energy is reflected by earth’s surface. we use the term albedo to describe the reflected energy. albedo of an object is the ratio of the reflected radiation to the total radiation reaching the object. a value of 0 means no energy is absorbed by the object, whereas a value of 1 means that all of the energy is absorbed. in this way, the albedo of an object can influence earth’s atmospheric temperature.
