Intro to Science Test

Front

First step of scientific method

Back

Observation

Answer explanation

The first step of the scientific method is observation. This involves gathering information and noticing phenomena, which leads to questions and further investigation.

Front

First thing you do AFTER finishing an experiment

Back

Analyze the data

Answer explanation

After conducting an experiment, the first step is to analyze the data collected. This allows scientists to understand the results and determine if they support or refute the hypothesis before taking further actions.

Front

Purpose of repeating experiments

Back

To ensure reliable results

Answer explanation

Repeating experiments is crucial in scientific research to ensure the results are reliable. This helps confirm that findings are consistent and not due to random chance or experimental error.

Front

Variable in an experiment

Back

A factor that can change or is tested

Answer explanation

In an experiment, a variable is a factor that can change or is tested. This allows researchers to observe how different conditions affect outcomes, making it essential for experimentation.

Front

Final step of the scientific method

Back

Drawing a conclusion

Answer explanation

The final step of the scientific method is drawing a conclusion. This involves interpreting the results of the experiment and determining whether the hypothesis is supported or not.

Front

Control Variable

Back

Stays constant or doesn't change

Answer explanation

A control variable is a variable that stays constant or doesn't change during an experiment. This ensures that any observed effects can be attributed to the independent variable, making the results more reliable.

Front

Independent Variable

Back

Changed or manipulated in an experiment

Answer explanation

The independent variable is the one that is changed or manipulated in an experiment to observe its effect on the dependent variable. This choice correctly identifies the role of the independent variable.

Front

Testable Hypothesis

Back

If I water my plants more, then they will grow taller.

Answer explanation

The statement 'If I water my plants more, then they will grow taller.' is a testable hypothesis because it can be experimentally verified by measuring plant growth with varying water levels.

Front

Dependent Variable

Back

What is observed or measured in an experiment

Answer explanation

The dependent variable is the outcome that is measured in an experiment. It responds to changes made to the independent variable, allowing researchers to assess the effect of their manipulations.

Front

Purpose of an experiment

Back

Test the hypothesis

Answer explanation

The purpose of conducting an experiment in the scientific method is primarily to test the hypothesis. This allows researchers to determine if their predictions about a phenomenon are supported by empirical evidence.
