Lessons 1 and 2 Quiz

A scientist observing the light given off by a star discovers that this star emits a kind of starlight never before observed by other scientists. Which of the following reactions would NOT be good science?

An observer listed the following properties of a mineral sample. A) The object is a dark grey rectangular solid. B) The object rusts when exposed to rain. C) The object most likely was purchased from a science catalog. D) The object is more dense than water. Which of there statements in an inference?

What values would be needed to calculate the mass of a solid mineral sample?

A student did an experiment to find the density of the mineral pyrite. The student measured and calculated the density of eight samples of pure pyrite. What would a graph of the data look like?

Which of the following is most likely to be an inference?

Quartz is a mineral with a density of 2.63 g/cm^3. If a sample of quartz was dropped into the graduated cylinder shown below, where would the quartz sample come to rest?

A student estimated the mass of a mineral sample to be 50g. Measurement showed it was actually 40g. What was the student's percent deviation?

Which is the greatest distance?

Why do objects float higher in seawater than they do in fresh water?

When aluminum foil is formed into a loose ball, it can float on water. But when the ball of foil is pounded flat with a hammer, the foil sinks. Why?

What is the approximate volume of 75 grams of pyrite?

What is the approximate density of pyrite?

Lillian looked up into the sky and estimated the clouds to be 1 kilometer above the ground. But the measurements by weather scientists showed them to actually be 10 kilometers above the ground. What was Lillian's percent error?

Which of the following professionals would be least likely to need training in the Earth sciences for his or her occupation?

According to the graph, which of the following caused the most weather-related fatalities in the United States from 1988 to 2005?

If government programs could eliminate all fatalities caused by extreme heat and winter storms, how would this most likely affect the number of weather deaths in the near future?

What was the general direction of movement of Hurricane Katrina from August 25 to August 28?

The map shows that Hurricane Katrina came ashore in the continental United States how many times?

According to this graphic, when are hurricanes most common in this region?

According to this graphic, which of the following conclusions is correct?

What was the relationship between the air pressure in Hurricane Katrina and the speed of the hurricane winds?

How did the strength of hurricane Katrina change from August 23 to August 30?

What is the mass of Earth?

From the paragraph, we can conclude that...

How do we know that Earth has no weight?

A metric ton is 1000 kg. According to the passage above, what is Earth's mass in metric tons?

Given that the density of Eris and Pluto are equal, Eris' size is [blank_start]larger[blank_end] than Pluto.

A(n) [blank_start]astronomer[blank_end] most likely discovered Eris.

If the mass of Pluto is 1.3 * 10^22 kilograms, the mass of Eris is approximately [blank_start]1.651 * 10^22[blank_end] kilograms.

Objects that have a density less than that of water will [blank_start]float[blank_end]. Objects that have a density greater than that of water will [blank_start]sink[blank_end]. Objects that have a density equal to that of water will [blank_start]be suspended[blank_end].
