• Absorption

• Refraction

• Reflection

What is the difference between reflection and refraction?

• Light bends when it is reflected and bounces off when it is refracted.

• Light bounces off when it is reflected and bends when it is refracted.

• Light travels in curved lines when it is reflected and straight lines when it is refracted.

• When light is refracted, it no longer travels.

Bifocals were invented in 1784 by Benjamin Franklin. He invented bifocals to make it easier to see both up close and far away. Bifocal eyeglasses 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 reflect light.

• The bifocal lenses refract light.

• The bifocal lenses make light less visible.

• The bifocal lenses absorb light.

When designing an experimental investigation, why is it important to test only one variable?

• Testing one variable explains what caused the change, once data has been gathered.

• Testing one variable collects inaccurate data and repeats the investigation more than necessary.

• Testing one variable decreases the reliability of the investigation.

• It is not necessary to test only one variable.
