Scientific Measurement (Part 1)

Front

What is scientific measurement?

Back

Scientific measurement is the process of quantifying observations using standardized units to ensure accuracy and consistency.

Front

What is the metric conversion from centimeters to millimeters?

Back

1 cm = 10 mm, therefore to convert cm to mm, multiply by 10.

Front

What is a direct relationship in scientific terms?

Back

A direct relationship indicates that as one variable increases, the other variable also increases.

Front

How do you calculate percent yield?

Back

Percent yield = (Experimental yield / Theoretical yield) x 100%.

Front

What is the formula for calculating percent error?

Back

Percent error = |(Experimental value - Theoretical value) / Theoretical value| x 100%.

Front

What is the significance of significant figures in scientific measurement?

Back

Significant figures indicate the precision of a measurement and help convey the certainty of the data.

Front

What is the difference between accuracy and precision?

Back

Accuracy refers to how close a measurement is to the true value, while precision refers to how consistent repeated measurements are.

Front

What is the SI unit for mass?

Back

The SI unit for mass is the kilogram (kg).

Front

What is the SI unit for temperature?

Back

The SI unit for temperature is the Kelvin (K), but Celsius (°C) is also commonly used.

Front

What is the purpose of a trend line in data analysis?

Back

A trend line helps to visualize the relationship between variables and can indicate the direction of the data.
