8th Grade Science Readiness Standards 2024-2025

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What ensures that daughter cells receive identical DNA during mitosis?

Back

Precise replication and separation of chromosomes.

Front

What does falling air pressure indicate during weather changes?

Back

Falling air pressure often indicates that low pressure allows storm systems to develop.

Front

What determines the color of a star?

Back

The color of a star is determined by its surface temperature.

Front

What happens when a star exhausts its hydrogen fuel?

Back

When a star exhausts its hydrogen fuel, it expands due to decreased core pressure.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is the role of pressure in weather systems?

Back

Pressure changes can influence weather patterns, with low pressure often leading to storm development.

Front

How does temperature affect the color of stars?

Back

Hotter stars emit more blue light, while cooler stars emit more red light.
