Observation
What is an observation?
A statement about something you notice using your senses
What is a scientific question?
A question that can be tested and answered through experimentation
What is a hypothesis?
An educated guess or prediction about the outcome of an experiment.
What is the purpose of an experiment?
To test the hypothesis and gather data.
What does analysis in the scientific method involve?
Examining data to determine if it supports or rejects the hypothesis.
Give an example of a qualitative observation.
The flower is red.
What makes a good scientific question?
A good scientific question is specific, measurable, and testable.
How should a hypothesis be structured?
A hypothesis should be structured as an "If… then…" statement.
What is a controlled variable?
A variable that is kept constant throughout the experiment.
What are common methods of data analysis?
Graphing, statistical analysis, and comparison of results.
What is the difference between qualitative and quantitative observations?
Qualitative observations describe qualities, while quantitative observations involve numbers and measurements.
Give an example of a scientific question related to plant growth.
example: How does the amount of sunlight affect the growth of tomato plants?
Give an example of a hypothesis about water temperature and fish activity.
If the water temperature increases, then fish will be more active.
Why is it important to have a control group in an experiment?
It allows for comparison to see the effect of the independent variable.
Why is it important to keep detailed records during an experiment?
Detailed records allow for accurate analysis and replication of the experiment.
How can observations lead to scientific questions?
Observations can reveal patterns or anomalies that prompt questions about why or how something occurs.
Why is it important to ask questions in the scientific method?
Questions direct the research and experimentation process.
Why is it important to make a hypothesis before conducting an experiment?
It provides a basis for testing and guides the experimental design.
What are the two main types of variables in an experiment?
Independent variables (manipulated) and dependent variables (measured).
What might you do if your analysis does not support your hypothesis?
Reevaluate the hypothesis, consider errors, and possibly conduct further experiments.
Why is it important to make careful observations in science?
Careful observations ensure accurate data collection and help form valid conclusions.
How can you turn a general question into a specific scientific question?
By focusing on a particular aspect and specifying the variables involved.
What happens if the hypothesis is not supported by the experiment?
The hypothesis may be revised or rejected based on the results.
Describe the steps you would take to conduct a simple experiment.
Identify a question, formulate a hypothesis, design the experiment, collect data, and analyze results.
How can you communicate your analysis results effectively?
Through reports, presentations, and visual aids like charts and graphs.
