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.

When you mix cornstarch and water, you get something that many science sites call Oobleck. Under pressure, it feels like a solid, but when the pressure is removed, it flows like a liquid. What state of matter is it?
Answer:
This is a mixture, made up of particles of solid matter surrounded by a liquid. The mixture is not a single state of matter.
This is an important concept to understand, and it is seen in many things we use every day. A good example is the Egg States video, showing how a mixture of liquid and gas can seem to be a solid.
Before you try to decide if something is solid, liquid, gas, plasma, or some other state of matter, first make sure that it is a pure substance, and not a mixture of different states.

When you break the mineral calcite, it breaks into shapes with flat, smooth sides. This is an example of:
-
Cleavage
Yes! A mineral has cleavage when it breaks to form flat, smooth surfaces. -
Fracture
No. There are different kinds of fractures, but none of them form flat, smooth surfaces. -
Conchoidal
No. A conchoidal fracture is the shell-shaped break that is commonly seen when glass breaks. A conchoidal fracture is not flat.
-
Hardness
No. Hardness tells us how easily a mineral can be scratched, not how it breaks.

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.

Hydroelectric
Yes. The lake water that provides hydroelectric power is replenished every time it rains. -
Natural Gas
No. Natural Gas is a fossil fuel, and takes millions of years to form. -
Fuel Oil
No. Fuel oil comes from petroleum, which requires extremely long periods of time to form.
