When a scientist makes a new discovery, other scientists usually do exactly the same experiment. Why?
-
They want to get part of the credit.
No. While replicating an experiment is very important, the scientists who do it usually don't get much credit for their work unless they discover an error in the original experiment. -
Repetition is part of the scientific process.
No. Repetition is when scientists repeat their own experiment several times, not when other scientists do the same experiment. -
They think they can make changes to improve the experiment.
No. By doing exactly the same experiment, they are not changing anything. Instead, they are replicating the experiment as closely as possible. -
Replication is part of the scientific process.
Yes. By replicating the experiment, other scientists can help verify that the results are accurate. There is always a possibility that there was some unnoticed influence on the original experiment, and replication can help spot that.

I used a Density Column to show that olives are denser than cherry tomatoes. To follow proper scientific procedure, the experiment needs to be checked by repetition and replication. What is the difference between repetition and replication?
-
Repetition means that I do the same experiment again. Replication means that other people do exactly the same experiment again.
Yes! To confirm your results it is important for you to repeat exactly the same experiment again (repetition) and then for other people to do exactly the same experiment again. (replication). If any of the results from repetition or replication are different from your original data, your original results are NOT confirmed, and you need to do more work. -
Repetition means that I do the same experiment again. Replication means that I do the experiment again after correcting errors.
No. Replication is when other people to do exactly the same experiment. -
Repetition means that I do the same experiment again. Replication means that other people try to improve on my experiment.
No. Replication is when other people to do exactly the same experiment. -
Repetition means that I do the experiment again after correcting errors.. Replication means that other people do exactly the same experiment again.
No. Repetition means that I do the same experiment again.

The yellow lines show how light is bent as it passes through a magnifying glass. This is an example of:
-
Absorption
No. The glass is clear, telling us that very little of the light is being absorbed. Absorption does not bend the light. -
Diffusion
No. Diffusion is the scattering of light as it is reflected in many different directions. Diffusion would make the rays of light go in many different directions. -
Refraction
Yes! Refraction bends light as it moves from one substance to another. As the light passes through the curved lens of the magnifying glass its path is changed, bending the rays towards the focal point. -
Reflection
No. While some light is reflected from the glass, it is not responsible for the bending of the light.
