Correct Answer
C. Identify a Problem, Form Hypothesis, Run Experiment, Results, State ConclusionExplanation
The correct answer is "Identify a Problem, Form Hypothesis, Run Experiment, Results, State Conclusion". This sequence of steps accurately represents the scientific method. First, a problem or question is identified. Then, a hypothesis is formed, which is a proposed explanation for the problem. Next, an experiment is conducted to test the hypothesis. The results of the experiment are analyzed and a conclusion is drawn based on the findings.Rate this question:

An observation is
- A.
Anything from the natural world
- B.
Something in your brain
- C.
Something about an animal
- D.
Anything from your five senses
Correct Answer
D. Anything from your five sensesExplanation
An observation refers to the act of perceiving or noticing something using our five senses (sight, hearing, touch, taste, and smell). It involves gathering information or data about the external world through our senses, allowing us to gain knowledge and understanding of our surroundings. This can include anything that we can see, hear, touch, taste, or smell, such as objects, sounds, textures, flavors, or scents. Observations are essential in scientific research and everyday life to gather information and make informed decisions.Rate this question:

- A.
Beaker
- B.
Centimeter
- C.
Petri Dish
- D.
Graduated Cylinder
Correct Answer
D. Graduated CylinderExplanation
A graduated cylinder is a cylindrical container used to measure the volume of liquids accurately. It has markings or graduations on the side, which allows for precise measurements. In this context, if someone wants to measure the amount of rain that has fallen in the past day, a graduated cylinder would be a suitable device to use as it can accurately measure the volume of the collected rainwater.Rate this question:

A student wants to find out how much water he uses to feed a plant. He takes the watering can and dumps water into the following container. What type of scientific tool is this?
- A.
A Beaker
- B.
A graduated cylinder
- C.
A periodic table of elements
- D.
A cup
Correct Answer
A. A BeakerExplanation
The correct answer is a beaker. A beaker is a scientific tool commonly used in laboratories for holding, measuring, and mixing liquids. It has a wide mouth and a flat bottom, making it easy to pour and stir substances. In this scenario, the student is using the beaker to measure the amount of water he uses to feed the plant.Rate this question:

A variable is anything that...
- A.
Looks cool
- B.
Smells like its an experiment
- C.
Can change an experiment
- D.
Is not known
Correct Answer
C. Can change an experimentExplanation
A variable is something that has the ability to alter or influence an experiment. It is a factor or condition that can be changed or manipulated by the researcher in order to observe its effect on the outcome of the experiment. By varying the variable, the researcher can determine the cause and effect relationship between different factors and the results of the experiment.Rate this question:

Which statement below is NOT an observation...
- A.
The sky turned very dark before it rained
- B.
I think that the chemicals will fizz when I mix them.
- C.
The rock's surface was rough and jagged
- D.
I noticed my rabbit drank 1 bottle less water this week than last week
Correct Answer
B. I think that the chemicals will fizz when I mix them.Explanation
The statement "I think that the chemicals will fizz when I mix them" is not an observation because it is based on the person's thoughts or beliefs rather than a direct observation of a physical phenomenon. Observations are typically based on objective data that can be perceived through the senses, while this statement reflects a subjective opinion or expectation.Rate this question:

If a scientist wants to find out if a new dog food makes puppies grow faster than regular dog food, he needs to know all the variables. Which of the items listed below could be a variable? 1- How much dog food to give the puppies at each meal 2- The type of puppy the scientist uses 3- The age of the puppies in the experiment 4- How long he feeds the puppies the new food for.
- A.
1 only
- B.
2 only
- C.
1,2, and 4 only
- D.
All of the items listed are variables
Correct Answer
D. All of the items listed are variablesExplanation
All of the items listed are variables because they are factors that can potentially affect the outcome of the experiment. The amount of dog food given at each meal, the type of puppy used, the age of the puppies, and the duration of feeding the new food are all factors that can influence the growth rate of the puppies. Therefore, all of these items can be considered variables in this experiment.Rate this question:

A researcher was studying how water pollution affects fish populations in a local stream. He took samples from two areas, A and B, and these were his results. td p { margin-bottom: 0in; }p { margin-bottom: 0.08in; } Did sample have pollutants? Number of fish observed Site A Yes 3 Site B No 15 If you were the researcher, What CONCLUSION would you state about this data?
- A.
Pollution doesn't change how many fish there are
- B.
Pollution might affect the number of fish living in a stream
- C.
Pollution makes water dirty so fish can't breathe
Correct Answer
B. Pollution might affect the number of fish living in a streamExplanation
Based on the data collected, it can be concluded that pollution might affect the number of fish living in a stream. This conclusion is drawn because in the area with pollutants (Site A), only 3 fish were observed, whereas in the area without pollutants (Site B), 15 fish were observed. This suggests that the presence of pollutants may have a negative impact on fish populations.Rate this question:

Just because one scientist says something is true....
- A.
You should believe him/her because they are a scientist
- B.
You should never believe anything he says
- C.
You should do the same tests and see if you reach the same conclusion
Correct Answer
C. You should do the same tests and see if you reach the same conclusionExplanation
The correct answer is "You should do the same tests and see if you reach the same conclusion." This is because scientific claims should be based on evidence and reproducibility. By conducting the same tests and reaching the same conclusion, it helps to validate the initial claim and ensures that it is not based on an isolated or biased observation. It promotes the scientific method and encourages critical thinking and independent verification of results.Rate this question:

If you wanted to know what kind of sports ball bounced the highest, what answer would be the best hypothesis to test?
- A.
If a soccer ball and a tennis ball are bounced, both might bounce, but they could be different
- B.
I think this is the wrong experiment
- C.
If a soccer ball and tennis ball are dropped from 3 feet up, then tennis ball will bounce higher.
- D.
The tennis ball will be more bouncy, but the soccer ball will go higher.
Correct Answer
C. If a soccer ball and tennis ball are dropped from 3 feet up, then tennis ball will bounce higher.Explanation
The best hypothesis to test in order to determine what kind of sports ball bounces the highest is: "If a soccer ball and tennis ball are dropped from 3 feet up, then the tennis ball will bounce higher." This hypothesis suggests conducting an experiment by dropping both balls from the same height and observing which ball bounces higher. This experiment would provide a clear comparison between the two balls and determine which one has a higher bounce.Rate this question:

Everywhere
- B.
What is science?
- C.
In the lab only
- D.
In your head
Correct Answer
A. EverywhereExplanation
Science is everywhere because it is a systematic and logical approach to understanding the natural world. It is not limited to a specific location or confined to a laboratory. Science can be observed and applied in various aspects of our daily lives, such as in our homes, workplaces, and even in nature. It encompasses the study of the universe, living organisms, physical phenomena, and much more. Science is a universal concept that exists in all places and is not limited to a specific setting or space.Rate this question:

How many variables should you TEST at a time in an experiment?
- A.
76,450,304,129,102.2
- B.
0
- C.
1
- D.
17
Correct Answer
C. 1Explanation
In an experiment, it is recommended to test only one variable at a time. This is because if multiple variables are tested simultaneously, it becomes difficult to determine which variable is responsible for the observed results. By testing one variable at a time, it allows for a clear understanding of the impact of that specific variable on the experiment's outcome.Rate this question:
