During a tarot card reading, Jane found out that she was going to find fortune in another state. Jane then sold all of her personal items and moved. Based on a scientific approach, why was this potentially not a smart move for Jane?
Jane should realize that tarot card reading is not testable, observable, and repeatable.
Jane did not have a control to compare to.
Jane only had one session with a tarot card reader.
Jane could have interpreted the results incorrectly.
For her science fair project, Samantha would like to see how different substances affect bone mass. She collects several chicken leg bones from the grocery store, records each bone’s mass, and soaks them in different liquids for 48 hours. After 48 hours Samantha measures the mass of each bone again.
In Samantha’s experiment, which of the following should be a constant in all test groups?
l. amount of liquid
ll. initial mass of the bone
lll. temperature of liquid
l only
ll only
l and lll
II and III
Which process is most difficult for scientists to perform when learning about the Solar System?
verifying data
applying theoretical ideas
reviewing published results
performing a controlled experiment
In the early 1900s, several scientists supported the now disproved concept that "Earth is continually shrinking". Supporters claimed that the many landforms on Earth's surface and under the ocean provided proof that it was indeed shrinking. This concept explained that mountains form as Earth becomes smaller and the continental crust crumples together. It went further to predict that volcanoes and mountain ranges occur randomly. Which of these terms may be used to best define this concept?
scientific law
scientific theory
scientific evidence
scientific hypothesis
A scientist claims that flowers grow better in acidic soil than in basic soil. What should occur to make this a valid scientific claim?
The claim must be tested only in natural settings.
The claim must be supported by only one set of data.
The claim must be supported by experimental evidence.
The claim must be researched by the same group of scientists.
It takes cars a longer amount of time to stop on the dry road than on the icy road.
The amount of time it takes a car to stop depends on the car, not on the road conditions.
The surface of the road does not make a difference in the amount of time it takes cars to stop.
It takes cars a longer amount of time to stop on the icy road than the on the dry road.
Students observe mold growing on a slice of bread. Which of the following is the best tool to use to observe the physical surface of the mold?
beaker
microscope
graduated cylinder
triple beam balance
coffee
diet soda
lemon juice
milk
Thomas is studying a piece of bread that is partially covered in mold. Thomas uses a microscope to examine the mold on the bread. After one week, he writes the following notes in a lab book:
The mold is alive.
The mold has an odor.
The mold has many cells.
The mold sample size is increasing.
The mold is greenish-gray and fuzzy.
Which note about the mold is an inference?
The mold is alive.
The mold has an odor.
The mold has many cells.
The mold is greenish-gray and fuzzy.
Which of the following examples uses scientific evidence to support the claim that is made?
Photographic evidence indicates that Bigfoot lives alongside grizzly bears in the Cascade Mountains.
The fact that Brazil has won the soccer World Cup more than every other nation is evidence that Brazilians are clearly the world’s best soccer players.
A population study using fish living in both contaminated and uncontaminated aquatic environments indicates that trout are more sensitive to environmental change than salmon.
A study of predictions about the outcome of sporting events shows that certain television networks are more likely to be correct because they were correct more than 80% of the time last year.
A student is testing a model rocket she constructed. She writes down the following information during the testing.
The rocket launched at 11:20 a.m. Eastern Standard Time. The rocket burned fuel more efficiently this trial than previously. The rocket remained in the air for 15.6 seconds after launch. The rocket landed within one kilometer from the launching site.
Which information written by the student represents an inference rather than an observation?
The rocket launched at 11:20 a.m. Eastern Standard Time
The rocket burned fuel more efficiently this trial than previously.
The rocket remained in the air for 15.6 seconds after launch.
The rocket landed within one kilometer from the launching site.
Reptile fossils found on the northwestern coast of Africa and on the eastern coast of South America are very similar in appearance. Which is the most likely inference that can be drawn from this observation?
Birds evolved from reptiles.
The same species evolved independently on these two separate continents.
The African and South American continents may have been once joined.
A meteor strike caused the extinction of the dinosaurs.
A student is studying about flowering plants. Which action performed by the student is NOT science?
The student lists the flowers that he thinks are the most colorful.
The student compares the growth of a species of flowering plant using different types of fertilizer.
The student counts the number of plants in a habitat and records the total number of each species.
The student videotapes how bees pollinate flowers.
Scientists who are part of the Intergovernmental Panel on Climate Change publish reports containing evidence of global warming. Which type of data would support the conclusion that global warming is currently occurring?
yearly records of temperature measurements over several decades
tree ring analysis that correlates to periods of droughts
ice core analysis that estimates historical climates
the prior year's precipitation measurements in the United States
Which observation contributes the most direct information to make an inference about the parenting ability of alligators?
The nest of one female alligator can have 35 to 90 eggs.
Female alligators build a nest of plant materials up to 10 feet wide
Female alligators defend their young for the first few years.
Mating between male and female alligators occurs in late spring.
Which statement expresses why using a compound light microscope is not better for viewing structures of single-cell organisms than a Transmission Electron Microscope (TEM)? (SC.912.L.14.4)
Compound Microscopes uses visible light
Compound Microscopes use a glass lens and a TEM uses an electromagnetic lens.
Compund Microscope uses a higher magnification than TEM
Compound Microscope uses 3-D magnification instead of 2-D.
