What’s the evidence that supports the claim in Claim, Evidence, Reasoning?

• Measurements of temperature changes

• Observations of color changes

• Both measurements and observations

• None of the above

Answer explanation

The correct choice is 'Both measurements and observations' because evidence supporting a claim can include quantitative data like temperature changes and qualitative data like color changes, providing a comprehensive basis for the claim.

Explain how scientific principles can validate a claim using evidence.

• Scientific principles help in systematically analyzing evidence to support a claim.

• Evidence is independent of scientific principles and stands alone.

• Scientific principles often contradict evidence-based claims.

• Evidence is always more reliable than scientific principles.

Answer explanation

Scientific principles provide a framework for evaluating and interpreting evidence, ensuring that claims are supported by systematic analysis rather than personal belief or anecdote.

What is the first step in the Scientific Method?

• Design Experiment

• Research

• Ask a Question

• Gather and Analyze Data

• Form Hypothesis

Answer explanation

The first step in the Scientific Method is to 'Ask a Question'. This initiates the process of inquiry and sets the stage for further investigation, leading to research and hypothesis formation.

The correct symbol for the SI unit for temperature is _______.

• K

• °F

• °C

• °K

Answer explanation

The correct symbol for the SI unit of temperature is 'K', which stands for Kelvin. The other options, °F and °C, represent Fahrenheit and Celsius, respectively, while °K is an outdated notation.

Density is derived from _______ divided by volume.

• length

• time

• temperature

• mass

Answer explanation

Density is defined as mass divided by volume. Therefore, the correct answer is mass, as it is the quantity that, when divided by volume, gives the density of an object.

What type of graph is used to display the following data?

• Line graph

• Bar graph

• Pie chart

• Histogram

Answer explanation

A line graph is ideal for displaying data that shows trends over time or continuous data. It effectively illustrates changes and relationships between variables, making it the correct choice for this type of data.

What is the independent variable in the graph?

• Days of the Week

• Temperature

• Amount of Rainfall

• Population Size

Answer explanation

The independent variable is the one that is manipulated or changed in an experiment. In this case, 'Days of the Week' is the variable that likely influences the other measurements like temperature and rainfall.

What is the dependent variable in the graph?

• Number of shooting stars

• Time of observation

• Location of observation

• Type of telescope used

Answer explanation

The dependent variable is what is measured in an experiment. In this case, the graph likely shows the 'Number of shooting stars' as it depends on factors like time, location, and telescope type.
