6th Grade Earth and Space Science Review

Flashcards about Earth and Space Science

What should a student use to support scientific understanding when defining a problem from the sixth-grade curriculum?

Appropriate reference materials

Why should scientific investigations be?

Replicable

What is the difference between replication and repetition in scientific investigations?

Replication is done by others, while repetition involves multiple trials by the same investigator.

What is the key difference between an experiment and other types of scientific investigations?

An experiment involves the identification and control of variables.

What is the value of scientists discussing their methods and results?

To compare, negotiate, and improve understanding among groups.

What role does creativity play in science?

Science involves creativity in designing experiments and in creating explanations that fit evidence.

What elements are involved in scientific investigations?

Collection of relevant empirical evidence, logical reasoning, and imagination in devising hypotheses, predictions, explanations, and models.

What can be said about scientists who contribute to scientific knowledge?

Scientists come from all kinds of backgrounds and possess varied talents, interests, and goals.

What is a scientific theory?

A well-supported and widely accepted explanation of nature, not simply a claim by an individual.

What is a scientific law?

A description of a specific relationship under given conditions in the natural world.

What is one of the listed advantages of scientific experiments?

Easily replicable to verify outcomes.

What is one of the listed disadvantages of scientific experiments?

Does not necessarily represent real-world situations due to controlled variables.

What is one of the listed advantages of scientific observations?

Can answer questions where experimentation is impossible and are real-world situations in natural environments.

What is one of the listed disadvantages of scientific observations?

Difficult or no control of variables in a controlled environment.

What is the most likely cause for drastically different water temperature readings taken at the same location.

Faulty equipment

Name a few types of scientists other than a meteorologist that are interested in weather and climate.

Climatologists or environmental scientists.

Why might grass grow at different rates even when planted the same way?

Differences in soil content or seed quality.

Name a method that geologists could use to understand how mountains form.

Analyzing rock formations or studying tectonic plate movements.

How is heat transferred through conduction?

Heat transfer through direct contact. Example: touching a hot stove.

How is heat transferred through convection?

Heat transfer through the movement of fluids (liquids or gases). Example: boiling water.

How is heat transferred through radiation?

Heat transfer through electromagnetic waves. Example: the sun warming the Earth.

What directly affects the path of the large air masses?

Jet stream winds.

What force keeps the planets in orbit around the Sun?

Gravity.

What is one way our atmosphere protects human life?

It contains gases that insulate the planet and protect living organisms from hazardous radiation.

What unit do scientists use to describe distances in space?

Astronomical unit (AU) and Light year (ly).

What name is given to the shape of the galaxy we live in?

Spiral Galaxy

Which planet would a person weigh the least on?

Mars

Which planet would a person weigh the most on?

Jupiter

What happens to an object's mass when moving from planet to planet?

Mass stays the same

What is the relationship between mass and gravity?

When mass increases, gravity increases. When mass decreases, gravity decreases.

What is the relationship between distance and gravity?

When distance decreases, gravity increases. When distance increases, gravity decreases.

In a main sequence star, what is the relationship between a star's luminosity and its temperature?

The hotter the star, the more luminous it is.

In which layer of the sun is energy being produced?

Core

According to the geocentric model, what is at the center of the solar system?

Earth

Type of power the rover most likely uses

Solar power

What does passing winds from west to east across North America signify?

Weather systems are moving from west to east
