In the Yeast and Sugar video, I added different kinds of sugar to bottles with yeast and warm water. One of the bottles was a control. What should have been in that bottle?
-
Just water
No. With just water, you are removing two variables, the yeast and the sugar. You only want to remove the independent variable.
-
Water and yeast
Yes! A control should be exactly like the others, but without the independent variable (the variable you are changing in the experiment.) In this case, the variable you are changing is the kind of sugar, so the control should have everything except for the sugar. -
Water and sugar
No. The yeast is not the independent variable, so leaving it out would not be correct. -
Water and salt
No. Adding salt would be adding a new variable, which is not correct.

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.

Which of the following observations is NOT scientifically testable?
-
Butterflies have pretty wings.
Yes! Pretty is an opinion, and can vary from person to person, so it is NOT scientifically testable. -
Butterflies have six legs.
No. This could be tested by counting the legs of a variety of butterflies. -
Butterflies can sting like bees.
No. A claim does not have to be true to be testable. Examination of a variety of butterflies would show that they do not have stingers. -
Most butterflies drink nectar from flowers.
No. This could be tested by observing the feeding habits of butterflies.
Explain more about it.
If I said that butterflies did not have six legs, you could show me physical evidence by counting their legs. After counting the legs, the physical evidence would show that butterflies have six legs.
If I said that I don't think butterfly wings are pretty, you could show me wings that you think are pretty, but I might not agree with your opinion. "Pretty" is not something that we can measure. What is pretty to one person might not be pretty to another, so it is not a testable property.

I wanted to test a new fertilizer, to find the best concentration for my garden. I divided my garden into four sections and put a different amount of fertilizer in each section.
My test results showed that using 10 grams of fertilizer per gallon made the plants grow faster and bigger. To follow proper scientific guidelines, what should I do next?
-
Apply 10 grams of fertilizer per gallon to all the plants in my garden.
No. While that might make my garden grow well, it would not provide more evidence that this was the best mixture of fertilizer -
Do the same experiment over again.
Yes! Repetition is an important part of the scientific process. If my hypothesis is correct, I should get the same results every time I repeat the experiment. -
Do the same experiment, but use a different fertilizer.
No. Using a different fertilizer would be testing a different variable. I wanted to find the best concentration of the original fertilizer, so testing a different fertilizer would not help with that. -
Publish my results, so that other scientists could replicate my experiment.
No. Replication is an important step, but I should repeat my experiment several times to be sure that I get consistent results before I ask other scientists to try replicating it.
