Which of the following statements is scientifically testable?
-
These alligators are scary.
No. Being scary is not a physical property. Instead, it is an opinion. Some people might think they are scary, while other people might think they are not. -
These alligators have sharp teeth.
Yes! Careful observation would show that all three of these alligators have very sharp teeth. Anyone who put their hand into the mouth of these alligators would find out quickly that sharp teeth are a measurable, physical property that is scientifically testable.Remember that scientifically testable properties are going to be the same, no matter who tests them. For example, these alligators each have four legs, scaly skin, and lungs for breathing air. They are carnivorous, which means that they eat other animals. They are reptiles, and they lay eggs.
All of that information is based on physical evidence that can be checked and verified. You could count their legs, examine their skin, etc. These things are scientifically testable.
On the other hand, opinions are a property of the observer, not the object. I may think alligators are interesting. Someone else may thing they are scary, or ugly, or boring. You could test different people, to see if they think alligators are scary, but you can't test the alligator to see if it is scary. Opinions are not scientific evidence about the object.
-
These alligators have ugly eyes.
No. Again, this is an opinion, not a measurable, physical property. I happen to think that alligators have pretty eyes. -
These alligators are lazy.
No. Lazy is not a measurable property. I might call them lazy, but you might think that they are just waiting for something tasty to walk by. Lazy is an opinion, and is not scientifically testable.

This layer of rock contains fossilized tracks from a dinosaur (Dilophosaurus). The black object is my cell phone for size reference. What kind of rock is it?
-
Igneous
No. Igneous rocks formed from magma or lava. An igneous rock would not have fossilized dinosaur tracks. -
Sedimentary
Yes! Sedimentary rocks are deposited by wind, water, ice, or gravity, and they often contain fossils. The presence of fossils is one of the indications that a rock is probably sedimentary. -
Metamorphic
No. Metamorphic rocks have been changed by heat and pressure from a different kind of rock. The metamorphic process would have destroyed the tracks. -
It is not rock.
No. These dinosaur tracks are in rock.

The Earth stays in orbit around the Sun because:
-
The Sun's gravity pulls on the Earth
This is only part of the answer. -
The Earth's gravity pulls on the Sun
This is only part of the answer. -
The gravity of the Sun and the Earth pull on each other
Yes! The gravitational attraction between the Earth and the Sun is a result of both the Sun pulling on the Earth and the Earth pulling on the Sun. -
Gravity does not keep the Earth in its orbit.
No. Without the pull of gravity, the Earth would continue moving in a straight path instead of curving around the Sun.

The brown spots on this fern contain spores. How are spores different from seeds?
-
Spores are much smaller, because they do not contain stored food for the young plant.
That is part of the answer. Most seeds contain stored food for the developing plant. Orchid seeds are an exception.. -
Spores are a form of asexual reproduction.
That is part of the answer. Spores contain only the genetic material from the parent plant. -
Spores develop into a different kind of plant from the parent.
This is part of the answer. Ferns have alternation of generations, which means that the spores grow into a plant called a prothallia. The prothallia produces male and female sex cells, which join, and grow into another fern plant. -
All of the above.
Yes! All three of the answers are correct.

These are the four stages of a mealworm's life cycle. What kind of life cycle is it?
-
Incomplete metamorphosis
No. For an incomplete metamorphosis, there are only three stages: egg, larva, and adult. The young also look very similar to the adults. The mealworm larva looks very different from the beetle. -
Complete metamorphosis.
Yes! For a complete metamorphosis, the animal goes through four stages: egg, larva, pupa, and adult. -
Full metamorphosis.
No. There is no life cycle called full metamorphosis. -
Partial metamorphosis.
No. There is no life cycle called partial metamorphosis.
