Which of the following best explains why it is harder to see your reflection in a rough surface than a smooth surface?

When light hits a rough surface, much of it is reflected in many different directions

When light hits a rough surface, much of it is absorbed into the substance

When light hits a smooth surface, much of it is refracted so that it bends

When light hits a smooth surface, the light is mostly converted to energy

What happens when light hits an object that it cannot pass through?

The light is reflected or absorbed

The light is refracted or absorbed

The light is reflected or refracted

The light is scattered or curved

Light travels into a camera lens to form a small, upside down image on the inside of the camera. Which of the following best describes why the lens flips and decreases the size of the image?

Light is transmitted by the lens

What happens when light strikes a dark, heavy object?

The light moves quickly through the medium

Light does not strike dark objects

Students performed an experiment testing refraction of objects in water. First, they recorded how objects looked in hot water. Then they used cold water to test if the appearance changed. What variable did students test in this experiment?

The student who performed the experiment

Time of day the experiment was performed

Before beginning an experiment, students were instructed to gather the materials necessary to classify objects with the properties of reflection or refraction. What objects could be used as materials that reflect light?

Water, piece of wood, and clear plastic container

After an experiment testing refraction of light in water, a student made the following conclusion: Objects look broken when they are in water so light is reflected in water. Was the student’s conclusion accurate?

No, because objects appear broken in water due to refraction of light

Yes, because when objects appear broken in water, they are reflected

Yes, because all objects can reflect light

No, because objects submerged in water do not appear broken

While investigating whether objects reflect or refract light, a student asked when would be an appropriate time to make a conclusion. What is a good response to this question?

No, because objects appear broken in water due to refraction of light

After performing experiments one time, a reliable conclusion can be made

No matter how many times an experiment is tested, you should never make a conclusion

Test the experiment several times to ensure your conclusion is accurate

While investigating whether objects reflect or refract light, a student asked when would be an appropriate time to make a conclusion. What is a good response to this question?

Bifocals were invented in 1784 by a famous scientist named Benjamin Franklin. He invented bifocals to make it easier to see both up close and far away. Bifocals are a type of glasses which have two different lenses. One lens helps people to see at a distance, and the other is for seeing up close. Why can people who are both nearsighted and farsighted see better through bifocals?

The bifocal lenses refract light

The bifocal lenses reflect light

The bifocal lenses make light less visible

The bifocal lenses absorb light

When exploring light in an outdoor investigation, which safety rule should be followed?

Wear sandals or open-toed shoes

When waiting for directions, play with your friends
