Which of the following observations is scientifically testable?
-
Honeybees are good insects.
No. "Good" is a generic term that could mean many different things in different situations. It is an opinion, not a testable property. This statement is NOT scientifically testable. -
Honeybees are important insects.
No. "Important" is a generic term that could mean many different things to different people. It is an opinion, not a testable property. This statement is NOT scientifically testable. -
Honeybees are pretty insects.
No. Some people might think that a honeybee is pretty, and some people might not. It is an opinion, not a testable property. This statement is NOT scientifically testable. -
Honeybees are not insects.
Yes! While this statement is not correct, it is scientifically testable. You could examine the bee to see that it does fit the definition of an insect. This statement is IS scientifically testable.

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.

We enjoy the hummingbirds that visit our feeders. I am trying to find the mixture of sugar and water that they like the best.
Each day, I put out four feeders with different amounts of water and sugar. At the end of each day, I measure to see how much of each the hummingbirds drank. Which of the following is NOT an important part of this experiment?
-
One of the feeders should only contain water, with no sugar.
No. This IS an important part of the experiment. The feeder without any sugar is the control. If the hummingbirds drink just as much pure water, it would indicate that the sugar is not important. -
The feeders should be placed randomly every day.
No. This IS an important part of the experiment. If you always put the same mixture in the same location, the results may be because the birds like that location instead of because they like the amount of sugar. -
I should repeat this experiment every day for several weeks.
No. This IS an important part of the experiment. The more times you repeat the same test, the more likely you are to get accurate results. -
The different mixtures should be colored different colors with nontoxic food coloring.
Yes. This is NOT an important part of the experiment. It would add a second variable to the experiment, which is a bad thing. You want everything to be the same for each sample, with the only difference being the amount of sugar. If you used different colors and different amounts of sugar, you would not know whether the results were due to the color or the sugar.

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 want to test a new fertilizer, to find the best concentration for my garden. To do this, I plan to divide my garden into four sections.
Section A. I will use 5 grams of fertilizer per gallon each time I fertilize.
Section B. I will use 10 grams of fertilizer per gallon each time I fertilize.
Section C. I will use 15 grams of fertilizer per gallon each time I fertilize.
For section D, how much fertilizer per gallon should I use?
-
20 grams of fertilizer per gallon.
No. This would be a good thing to test, but for this to be a proper science experiment, it is not the correct answer. -
30 grams of fertilizer per gallon.
No. This would be a good thing to test, but for this to be a proper science experiment, it is not the correct answer. -
1 gram of fertilizer per gallon.
No. This would be a good thing to test, but for this to be a proper science experiment, it is not the correct answer. -
No fertilizer at all.
Yes. For this type of experiment, you need to have a control group. That is a group of test subjects that you do not do anything to. If the control group with no fertilizer grows just as well as the other groups, then I would know that the fertilizer was not working.
