Max is designing an experiment.His question is:What is a logical way to make "ooblay" (cornstarch in water) without making a mess.Which of these answers his question:
- A.
Put paper towels around the area.
- B.
Mix it with a cleaning solution
- C.
Dump the finished product into a tesla coil
Correct Answer
A. Put paper towels around the area.Explanation
Putting paper towels around the area is a logical way to make "ooblay" without making a mess. This answer suggests that Max wants to prevent any spills or splatters while mixing cornstarch and water. By placing paper towels around the area, any potential mess can be easily absorbed and cleaned up, ensuring a neat and organized experiment.Rate this question:

Name the first step in the scientific method.
- A.
Imagine the end of the world
- B.
Ask questions
- C.
Make an experiment
- D.
Write down what supplies you'd need
Correct Answer
B. Ask questionsExplanation
The first step in the scientific method is to ask questions. This is important because it helps to identify the problem or topic that needs to be investigated. By asking questions, scientists can gather information, explore different perspectives, and formulate hypotheses. It is through questioning that scientists can begin to understand the phenomena they are studying and develop a clear direction for their research.Rate this question:

Jack and Kaleb are conducting an experiment for their question: What happens when you puncture a spray foam bottle.What do you think they will need?
- A.
A knife,a spray foam bottle,protective clothing.
- B.
A beaker,
- C.
A measuring stick
Correct Answer
A. A knife,a spray foam bottle,protective clothing.Explanation
Jack and Kaleb are conducting an experiment to find out what happens when you puncture a spray foam bottle. In order to carry out this experiment, they will need a knife to puncture the bottle, a spray foam bottle itself to observe the reaction, and protective clothing to ensure their safety while handling potentially harmful substances. The beaker and measuring stick mentioned in the other option are not necessary for this specific experiment.Rate this question:

Which variable could be measured during an experiment?
- A.
Independent Variable
- B.
Dependent Variable
Correct Answer
B. Dependent VariableExplanation
The dependent variable is the variable that is observed or measured during an experiment. It is the outcome or result that is being studied and is expected to change in response to the independent variable. In other words, it is the variable that depends on the independent variable and is used to assess the effect or impact of the independent variable. Therefore, the dependent variable is the variable that could be measured during an experiment.Rate this question:

Which could be a factor that remains at the same phases of an experiment?
- A.
Observation
- B.
Constant(s)
- C.
Technology
- D.
Variable(s)
Correct Answer
B. Constant(s)Explanation
A factor that remains at the same phases of an experiment is called a constant. Constants are variables that are kept consistent throughout the experiment and do not change. They are used as a baseline for comparison to measure the effect of other variables. By keeping certain factors constant, researchers can ensure that any observed changes or effects are due to the manipulated variables and not influenced by other factors.Rate this question:

Observation(s)
- B.
Inference(s)
- C.
Hypothesis
- D.
Technology
- E.
Scientific Method(s)
Correct Answer
D. TechnologyExplanation
Technology is the correct answer because it refers to the new products or tools that are created as a result of the knowledge gained through science. Technology involves the practical application of scientific knowledge to solve problems, improve efficiency, and enhance human lives. It encompasses various fields such as electronics, information technology, biotechnology, and more. Through scientific research and understanding, advancements in technology are made, leading to the development of innovative products and tools that benefit society.Rate this question:

What is an educated statement that could be tested called?
- A.
Observation(s)
- B.
Science
- C.
Hypothesis
- D.
Scientific Method(s)
Correct Answer
C. HypothesisExplanation
A hypothesis is an educated statement that can be tested. It is a proposed explanation or prediction based on observations, knowledge, or research. In the scientific method, a hypothesis is formulated before conducting experiments or gathering data to test its validity. It serves as a starting point for scientific investigations and helps to guide the research process.Rate this question:

What are step-by-step approaches to solving problems called?
- A.
Science
- B.
Technology
- C.
Scientific Method(s)
- D.
Inference(s)
Correct Answer
C. Scientific Method(s)Explanation
Step-by-step approaches to solving problems are called scientific methods. This is because scientific methods involve a systematic and logical approach to investigating and solving problems. It involves making observations, forming hypotheses, conducting experiments, analyzing data, and drawing conclusions. The scientific method is widely used in various fields of study, including the natural sciences, social sciences, and even in everyday problem-solving situations.Rate this question:

What is a conclusion about an observation called?
- A.
Hypothesis
- B.
Science
- C.
Inference(s)
- D.
Scientific Method(s)
Correct Answer
C. Inference(s)Explanation
A conclusion about an observation is called an inference. Inferences are made by using evidence and reasoning to reach a logical conclusion based on the available information. Inferences are an important part of the scientific method, as they help scientists draw conclusions and make predictions based on their observations. Hypotheses are proposed explanations for a phenomenon, while science is a broader term that encompasses the systematic study of the natural world. Therefore, the correct answer is inference(s).Rate this question:

What is it called if I use my senses to gather bits of information called?
- A.
Control(s)
- B.
Science
- C.
Hypothesis
- D.
Observation(s)
Correct Answer
D. Observation(s)Explanation
Observation is the correct answer because it refers to the act of using our senses to gather bits of information. When we observe, we carefully watch and listen to gather data and information about a specific phenomenon or situation. By using our senses, we can collect evidence and facts that can be analyzed and used to draw conclusions or make further investigations.Rate this question:

What is the 1st step to the scientific method?
- A.
Observe and Infer
- B.
Recognize the Problem
- C.
Plan the Experiment
- D.
Analyze your Data
- E.
Communicate
Correct Answer
B. Recognize the ProblemExplanation
The first step to the scientific method is to recognize the problem. This involves identifying and defining the specific issue or question that needs to be addressed through scientific investigation. Without recognizing the problem, it would be difficult to proceed with the other steps of the scientific method, such as formulating hypotheses, conducting experiments, and analyzing data.Rate this question:
