2024 8th Grade Science PSSA Practice Part 2

Front

What is the engineering design process?

Back

A series of steps that engineers follow to come up with a solution to a problem, including identifying the problem, generating possible solutions, creating a model, and testing the model.

Front

What is a solar eclipse?

Back

An event that occurs when the Moon passes directly between Earth and the Sun, blocking the Sun's light.

Front

What is the importance of testing in engineering?

Back

Testing allows engineers to evaluate the effectiveness of their designs and make necessary modifications to improve performance.

Front

What is gravity?

Back

A force that attracts two bodies toward each other, which is responsible for keeping planets in orbit around the Sun and moons in orbit around planets.

Front

What is the role of water in cave formation?

Back

Water dissolves limestone rock over time, leading to the gradual formation of caves.

Front

What is air resistance?

Back

A force that opposes the motion of an object through the air, affecting how far it can travel.

Front

What is the significance of model testing in engineering?

Back

Model testing helps identify flaws in design and ensures that the final product will function as intended.

Front

What is the difference between a lunar eclipse and a solar eclipse?

Back

A lunar eclipse occurs when Earth is between the Sun and the Moon, blocking sunlight from reaching the Moon, while a solar eclipse occurs when the Moon is between Earth and the Sun.

Front

What factors can affect the distance a car travels?

Back

Factors include the design of the car, the type of wheels, the amount of force applied, and environmental conditions like air resistance.

Front

What is the concept of orbital path?

Back

The curved path that an object follows as it moves around another object in space due to gravitational forces.
