When water freezes, it:
-
Condenses
No. Condensation happens when water vapor changes from a gas to a liquid. -
Contracts
No. Water does not take up less space when it freezes. -
Expands
Yes! Unlike most substances, water expands to take up more space when it freezes. -
Gains mass.
No. Changing from one state to another does not cause a change in mass.

Which part of the food web does this Red Shouldered Hawk fit into?
-
Producer.
No. A producer captures energy from sunlight, and stores it as food. To do that, the organism needs to contain chlorophyll. This hawk cannot use the energy of sunlight to produce its own food. -
Primary Consumer.
No. Primary consumers eat producers. This hawk does not eat living plants. -
Secondary Consumer
Yes! Secondary consumers eat other consumers. This hawk eats mice, snakes, and other animals. -
Decomposer
No. Decomposers break down dead and decaying organisms. The hawk may occasionally act as a scavenger, eating a freshly dead animal that it did not kill, but it is not a decomposer.

This baby praying mantis looks very much like its mother, but not exactly. What does that tell us about its life cycle?
-
It does not undergo metamorphosis.
No. While it does look similar to its parents, it lacks wings and other features which it will have as an adult. -
It has incomplete metamorphosis.
Yes! It has most of the features of an adult, and will gain the final adult features later in its life. -
It has complete metamorphosis.
No. For complete metamorphosis, the larva looks very different from the parent. -
It skipped metamorphosis.
No. While it does look similar to its parents, it lacks wings and other features which it will have as an adult.

The "strings" in a stalk of celery are made up of xylem and phloem. Which part of your body comes closest to serving the same function?
-
Skeleton
No. Your skeleton provides support and protection. In plants, the cell wall provides support and protection. -
Intestines
No. Your intestines allow you to absorb nutrients from your food. Plants make their own food, so they do not need a digestive system. -
Nerves
No. Your nerves carry signals to let the parts of your body communicate. They carry messages for your senses, to move your muscles, etc. Instead of having nerves, plants release chemicals that signal other parts of the plant. -
Blood Vessels
Yes! Your blood vessels carry water and nutrients to different parts of your body. In plants, the xylem is made up of tubes that carry water and some nutrients from the roots upwards to other parts of the plant. The phloem is made up of tubes that carry the sugar produce by photosynthesis to other parts of the plant. While they work in very different ways, your blood vessels serve basically the same function (carrying water and nutrients) as the xylem and phloem in plants.

The large, green stinkbug is drinking sap from this plant. That tells us that it is a:
-
Producer.
No. The plant is a producer. It captures energy from sunlight, and stores it as food. The stinkbug is eating the plant to get that energy. -
Primary Consumer.
Yes! The stinkbug is eating the sap from the plant (a producer) to get the energy it contains. -
Secondary Consumer
No. Secondary consumers eat other consumers. An animal that ate this stinkbug would be a secondary consumer. -
Decomposer
No. Decomposers break down dead and decaying organisms. The plant that the stinkbug is eating is still alive and growing.
