Flashcard 1: White Sands National Park & Scientific Experiments

Front

What is the primary factor that causes the crystals at White Sands to be small?

Back

Wind

Front

Which variable is most likely to affect the size of crystals formed in an experiment?

Back

Concentration of the solution

Front

What aspect of minerals that form sand can influence the color of the sand?

Back

Color

Front

In an experiment, how many variables should be altered at once to ensure valid results?

Back

One

Front

What was the controlled variable in the borax lab experiment?

Back

Length of pipe cleaner

Front

Define 'controlled variable' in the context of scientific experiments.

Back

A controlled variable is a factor that is kept constant to ensure that the results are due to the independent variable.

Front

What is the significance of wind in the formation of sand crystals at White Sands National Park?

Back

Wind helps to transport and shape the sand particles, contributing to their small size.

Front

Explain the role of concentration in crystal growth experiments.

Back

Higher concentration of a solution typically leads to larger crystals as more solute is available to form solid structures.

Front

What is the relationship between the color of minerals and the color of sand?

Back

The color of the minerals that compose the sand directly affects the overall color of the sand.

Front

Why is it important to change only one variable at a time in an experiment?

Back

Changing only one variable allows for clear identification of its effect on the outcome.
