In August of 2004, Hurricane Charley removed over six feet of sand from the beach at St. Augustine. Was that an example of erosion, weathering, both, or neither?
-
Erosion
Yes! This is an example of erosion. The sand was moved by wind and water.The term "weathering" causes confusion because it sounds like it has something to do with weather. In Earth Science, weathering means "breaking apart." Weathering breaks rocks apart. Erosion carries the pieces of rock to a different location.
-
Weathering
No. While this was caused by weather, it is not an example of weathering. Keep in mind that weathering means breaking down rocks into smaller pieces. The sand was not broken into smaller pieces. It was just moved from one place to another (erosion). -
Both erosion and weathering
No. This was erosion, but not weathering. -
Neither erosion nor weathering
No. Since the sand was moved, it was erosion.

I let mold grow on this stale loaf of bread. What part of the food web does the mold belong to?
-
Producer.
No. A producer captures energy from sunlight, and stores it as food. To do that, the organism needs to contain chlorophyll. This mold is green, but does not have chlorophyll. -
Primary Consumer.
No. Primary consumers eat producers. This mold does not eat living plants. -
Secondary Consumer
No. Secondary consumers eat other consumers. This mold does not eat animals. -
Decomposer
Yes! Decomposers break down dead and decaying organisms. The mold is a fungus that is breaking down and decomposing the bread to get energy from it..

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.

Cannonball Jelly fish are excellent swimmers, and Portly Spider Crabs often hitch a ride on them. What type of relationship is that?
-
mutualism
No. In mutualism, both organisms benefit. The jellyfish gets no benefit from the crab's hitchhiking. -
commensalism
Yes. In commensalism, one organism (the crab) benefits, and the other (jellyfish) is not affected. The crab gets free transportation, and the jellyfish is not helped or harmed. -
parasitism
No. For parasitism, one organism benefits, and the other is harmed. Neither the crab nor the jellyfish is harmed by this relationship. -
predation
No. In predation, one organism eats another. Neither the crab nor the jellyfish gets eaten in this relationship.
