In testing this piece of quartz, I found that it would scratch glass. What property was I testing?

  1. Hardness

    Yes! Hardness is a substance's resistance to being scratched. With a hardness of 7, quartz is hard enough to scratch glass.
  2. Cleavage

    No. Cleavage is the tendency of a mineral to break along planes of weakness to produce pieces with flat, smooth sides. Cleavage involves breaking, not scratching.
  3. Fracture

    No. Fracture is a property of minerals that do NOT break along planes of weakness to produce flat, smooth sides. This involves breaking, not scratching.
  4. Streak

    No. Streak is a test to see the color of a mineral when it is ground into a powder by scratching it on a porcelain streak plate. For streak, we are powdering the mineral, not scratching another substance.

This caterpillar is an example of which part of the food web?

  1. Producer.

    No. The plant is a producer. It captures energy from sunlight, and stores it as food. The caterpillar is eating the plant to get that energy.
  2. Primary Consumer.

    Yes! The caterpillar is eating the plant (a producer) to get the energy that is stored in its leaves.
  3. Secondary Consumer

    No. Secondary consumers eat other consumers. A bird that ate this caterpillar would be a secondary consumer.
  4. Decomposer

    No. Decomposers break down dead and decaying organisms. The plant that the caterpillar is eating is still alive and growing.

What do you have to do to replicate an experiment?

  1. You do the same experiment several times.

    No. Doing the same experiment several times is repetition, not replication.
  2. You do the same experiment that someone else did.

    Yes. By replicating an experiment exactly, you should get the same results as the original experiment.
  3. You do an improved version of someone's experiment.

    For replication, you do the experiment exactly as the original scientist did, without making any changes.
  4. You look for errors in someone's experiment.

    The purpose of replication is to verify, not to look for errors.

Cannonball Jelly fish are excellent swimmers, and Portly Spider Crabs often hitch a ride on them. What type of relationship is that?

  1. mutualism

    No. In mutualism, both organisms benefit. The jellyfish gets no benefit from the crab's hitchhiking.
  2. 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.
  3. parasitism

    No. For parasitism, one organism benefits, and the other is harmed. Neither the crab nor the jellyfish is harmed by this relationship.
  4. predation

    No. In predation, one organism eats another. Neither the crab nor the jellyfish gets eaten in this relationship.

MS-LS2-2 Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems.

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?

  1. 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.

  2. 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).

  3. Both erosion and weathering

    No. This was erosion, but not weathering.
  4. Neither erosion nor weathering

    No. Since the sand was moved, it was erosion.
