Repetition
Replication

Wiz Khalifa was mixing a batch of glue and borax solution to make silly putty and discovered a new substance that glows in the dark. He gave Cardi B his specific amounts of ingredients and the steps of his procedure. He asked Cardi B to try the experiment to see if she gets the same results. This is an example of what?
repetition
replication

Post Malone has taught his pet rat to run a maze. He thinks that the rat will go faster if he puts its favorite treat at the end. He has the rat run the maze ten times with the favorite treat and ten times with a regular food pellet. He uses a stopwatch to measure how long it takes for the rat to get to the reward. This is an example of what?
repetition
replication
Post's face tattoos
SC.7.N.1.2
Scientists frequently repeat the experiments of others scientists. Why is this important in science?
a. Scientists often ask each other for help in performing experiments.
b. Replication of experiments helps to confirm and verify results.
c. Scientists frequently perform other scientists’ experiments in order to practice their technique.
d. Repeating experiments is an effective way to make sure a laboratory is in optimal condition.
a
b
c
d
All (a) is made up of (b) The center of the (c) is called the (d) . This is part of the (e) Theory.
The (a) of (b) states that within undisturbed (c) rock layers, the (d) layer is at the bottom and the (e) layer is at the top.
Scientific knowledge may change as (a) is discovered.
In 1897, Joseph Thomson discovered that atoms contained electrons. He proposed a change in the atomic theory of that time, and the theory was modified because of his discovery. Since Thomson’s discovery, atomic theory has been further modified. What is the best explanation for why scientific theories are modified?
Theories more than ten years old are usually out of date.
Scientists want to prove that the work of other scientists is wrong.
New evidence that supports a change prompts scientists to modify earlier theories.
So much information is available today that it is harder to focus research and disprove theories.
The law of universal gravitation states that both mass and distance of objects affect the gravitational force between them. Gravitational force increases as the mass of the objects increase. Gravitational force decreases as distance between the objects increases. Why are these statements considered scientific law, and not scientific theory?
The statements tells what happens, and not why it happens.
The statements involve mass and distance measurements.
The statements explain the attractive force between two objects.
The statements predict what will happen under certain conditions.
Which of these can change when new evidence is presented?
theory
law
Which of these explain how a natural phenomenon works or happens?
theory
law
Which of these describes a natural phenomenon or relationship that always occurs under specific conditions
theory
law
Scientists create both scientific theories and scientific laws as they make observations and conduct experiments about the natural world. Which of the following statements most accurately compares the difference between scientific theories and scientific laws
science laws are based on evidence while science theories are not
science theories involve only biology, while laws involve all types of science
science theories involve mathematical equations, while science laws are based on observations
science theories are ideas that explain natural events, while science laws predict what will happen in a natural event.
The Law of Conservation of (a) states that (b) cannot be (c) or (d) , only (e) .
The Law of (a) of (b) states that energy cannot be (c) or (d) , only (e) .
The (a) of Universal Gravitation states that the force of (b) affects everything that has (c) in the universe. Also, the (d) two objects are, the (e) the gravitational force between them.
Alfred Wegner hypothesized that when the edges of separate continents are very similar; it suggests that these rocks were formed in the same way, implying that they were joined initially. To prove his hypothesis, Wegner collected fossil evidence from the east coast of South America and the west coast of Africa. Analysis of the fossils showed that they are similar, not only in structure, but in age. His conclusion was that these two continents were once joined. How would you best describe the results of Wegner’s experiment?
No conclusion can be drawn from the results
The results fail to support the hypothesis
The results are inaccurate
The results support the hypothesis
The plate tectonics (a) states that Earth's (b) is broken into (c) that move. These plate movements result in (d) , volcanoes, (e) building and separation of continents.
The (a) of (b) states that (c) (d) over (e)
