Science Skills Flashcards
What is the aim of scientific skills when conducting experiments?
The aim is to investigate and observe the effect of the independent variable (IDV) on the dependent variable (DV).
What is the role of a hypothesis in a scientific experiment?
The hypothesis states that if the IDV increases or decreases, then the DV will also increase or decrease and provides a reason for this expectation.
What do the terms IDV, DV, and CV stand for in the context of experiments?
IDV stands for independent variable (what you change), DV stands for dependent variable (what you measure), and CV stands for controlled variable (what you keep the same).
How can you enhance the reliability of experiment results?
Reliability can be improved by repeating the experiment, finding the average, comparing results, researching, and comparing with other sources.
How can you improve the accuracy of experiment results?
Accuracy is enhanced by using the correct equipment, ensuring exact measurements, and minimizing errors like parallax error, human reflex error, and reading error.
What does it mean to conduct a fair test in experiments?
A fair test involves having only one independent variable (IDV) and ensuring that all other variables are controlled except the IDV.
What is the purpose of studying trends and patterns in data analysis?
Trends help us understand the relationship between the independent variable and dependent variable, while patterns provide reasons for these trends.

Question: How can you structure a conclusion in an experiment?
Answer: A conclusion should restate the aim, provide a brief summary of trends and patterns, state whether results supported the hypothesis, and offer a reason why or why not.
What elements should be included in the title of a graph in scientific research?
The title should include the independent variable (IDV) and dependent variable (DV).
Where is the independent variable (IDV) typically plotted on a graph?
The IDV is usually plotted on the x-axis of a graph.
Where is the dependent variable (DV) typically plotted on a graph?
The DV is usually plotted on the y-axis of a graph.
When is a line graph typically used in scientific data representation?
Line graphs are used when data involves continuous measurement, showing trends over a range of values.
When is a column or bar graph typically used in scientific data representation?
Column or bar graphs are used when data is categorized and discrete, showing comparisons between categories.
What is the key verb used when you need to identify something in scientific discussions?
The key verb is “identify,” which means to name or list.
What does it mean to describe something in scientific discussions?
Describing involves identifying and providing features and characteristics, including trends and patterns.
