Why is it important to replicate experiments in the scientific method?

To confirm the results and ensure reliability

To make the experiment more expensive

How does the scientific method help scientists?

It provides a systematic way to gather and use information

It allows them to skip steps in research

It makes experiments unpredictable

What is a hypothesis?

A guess based on what you already know

Why is it important to share information with others after completing the scientific method?

To report your findings and allow others to learn from your results

If the second key opens the door after the first key did not, what is the most logical conclusion?

The first key was the wrong key

The second key was the wrong key

Which of the following best describes the sequence of steps in the scientific method shown in the image?

Question, Research, Predict, Experiment, Draw Conclusions

Hypothesis, Experiment, Research, Conclusion, Question

Experiment, Predict, Research, Question, Draw Conclusions

Research, Experiment, Question, Predict, Draw Conclusions

What is a hypothesis?

A testable explanation for a question or problem

A random guess without evidence

How does deductive reasoning help in forming a hypothesis?

By comparing new things to the rules of the natural world

By creating new rules for the natural world

Suppose you observe that all the plants in your garden grow towards the sunlight. Using inductive reasoning, what kind of hypothesis could you form?

Plants grow towards sunlight because they need light to survive.

Plants grow towards water sources.

Plants grow randomly in any direction.

Plants do not respond to environmental factors.

What is the main idea behind inductive reasoning as shown in the example?

Making a general rule based on many observations

Proving a theory using experiments

Applying a rule to a specific case

Why is it important to make many observations before developing a "Rule of Nature"?

To ensure the rule is based on evidence and patterns

To make the rule more complicated

To avoid using scientific methods

Which of the following best describes the process of deductive reasoning?

Drawing a specific conclusion from general premises

Making generalizations based on specific observations

Guessing based on incomplete information

What is a controlled experiment?

An experiment that only changes one variable at a time.

An experiment that changes all variables at once.

An experiment with no variables.

An experiment that does not record results.

Why is it difficult to understand the results when too many variables are changed in an experiment?

Because it makes it hard to know which variable caused the result.

Because experiments become more fun.

Because results are always the same.

Because variables do not affect experiments.

In a controlled experiment, what does the independent variable represent?

What you are measuring as a result

What is the dependent variable in a controlled experiment?

What you are measuring as a result

What type of reasoning can be used to make a hypothesis in the scientific method?

Inductive or deductive reasoning

Why is it important to test a hypothesis in a controlled experiment when using the scientific method?

To ensure that only the variable being tested affects the outcome

To make the experiment more complicated

To avoid making any observations

Why do scientists organize data into charts, graphs, or tables?

To make their results easily readable

To make their experiments longer

Based on the table shown, what happens to the height of the plant as more teaspoons of salt are added?

The height of the plant decreases

The height of the plant increases

The height of the plant stays the same

The height of the plant fluctuates randomly

What is the purpose of a descriptive title in a graph?

To explain what the graph is about
