Scientific investigation
What is a control variable in a scientific investigation?
A control variable is an element that is not changed throughout an experiment
What is a variable?
Variables are anything that can change or be changed in an experiment.
What is a graph?
A graph is a diagram that shows the data collected from the experiment.
What is the purpose of the results in a scientific investigation?
The purpose of the results in a scientific investigation is to present the findings of the study in a clear and objective manner, often through the use of tables, graphs, and descriptive text.
How many steps come before the conclusion?
6
what is an independent variable?
The independent variable is a variable that changes
In a line graph showing the temperature changes throughout the day, which axis would represent time, and which would represent temperature?
The x-axis would represent the time and the y-axis would represent the temperature.
How are results typically presented?
Results are typically presented using tables, graphs and charts.
How many steps are in a scientific investigation?
8
What is a dependent variable?
A dependent variable is a variable that you measure
What is a line of best fit ?
A line of best fit is a line that goes through the most points possible.
Can you explain the difference between qualitative and quantitative data in the context of scientific results?
Qualitative data refers to descriptive information that cannot be easily measured or quantified, such as observations or descriptions. Quantitative data, on the other hand, consists of numerical measurements or counts that can be analyzed statistically.
What is a scientific investigation?
A scientific investigation is a process of finding the answer to a question using various research methods.
Why are variables important in a scientific investigation?
Variables are important in science because they help us understand how different things relate to each other and why they change.
Which axis would have the dependent variable and which one would have the independent variable?
The dependent variable is on the y-axis and the independent variable is on the x-axis.
How does the conclusion differ from the results in a scientific investigation?
Conclusion is the final part of the Scientific investigation and it presents the findings briefly and describe them. In the Results Section, the data on graphs or charts.
What are all the steps of a scientific investigation?
Ask a question, make a prediction,write the variables, risk assessment, method, record your results,conclusion, evaluation
If you want to see if the amount of sunlight (independent variable) affects the growth of plants (dependent variable) in your school garden, what are 3 things you would keep the same for all the plants to make sure your experiment is fair?
You would keep the type of plant, the amount of water, and the type of soil the same for all the plants.
What are line graphs used for?
Line graphs in science help show how things change over time or in relation to each other, making it easier to understand patterns and predict what might happen next.
What key information should be included in the conclusion of a scientific investigation?
In the conclusion of a scientific investigation, it's important to include:
- A brief summary of the main findings.
- Explain what the results mean and why they matter.
