1️⃣ Steps of the Scientific Method
What is the first step in the scientific method?
What is observation?
The variable you deliberately change in an experiment is called what?
What is the independent variable?
After collecting data, what should scientists do before making conclusions?
What is analyze the data?
A farmer notices plants growing taller in one field than another. What is her observation?
The difference in plant height between fields.
An explanation that can be tested by experiments is called what?
What is a hypothesis?
After making an observation, what should a scientist do next?
What is ask a question or identify a problem?
The variable that changes as a result of what you manipulate is called what?
What is the dependent variable?
What type of graph is most commonly used to show change over time?
What is a line graph?
A rancher wonders if feed type affects cattle weight gain. What could be her hypothesis?
If cattle eat Feed A, they will gain more weight than cattle eating Feed B.
The series of steps scientists use to solve problems is known as what?
What is the scientific method?
What step involves making an educated guess or possible explanation?
What is forming a hypothesis?
The factors that remain the same throughout an experiment are called what?
What are constants?
What should a conclusion always relate back to?
What is the original hypothesis?
A student tests 3 types of fertilizer on tomato plants. What is the independent variable?
Fertilizer type.
Information collected during an experiment is called what?
What is data?
During which step do you carry out your experiment to test your hypothesis?
What is experiment or test the hypothesis?
What is the purpose of having a control group in an experiment?
To compare results and see the effect of the independent variable.
If the results of an experiment do not support the hypothesis, what should a scientist do next?
What is revise the hypothesis or retest?
A soil test shows different pH levels in various plots. What step of the scientific method is this?
Collecting data or analyzing results.
A prediction based on prior knowledge is called what?
What is an inference?
What is the final step where you summarize findings and decide if your hypothesis was correct?
What is draw a conclusion or communicate results?
If a farmer tests two types of fertilizer on corn, what is the dependent variable?
What is corn growth or yield?
When recording data, why is accuracy and consistency important?
To ensure valid and reliable results.
In a crop study, plants watered daily grew faster than plants watered weekly. What conclusion could you draw?
Frequent watering increases plant growth rate.
Why is repetition important in science experiments?
To verify accuracy and increase reliability of results.
