Which of these is NOT an example of a renewable energy source?

  1. Wood

    No. Because we can grow more trees, wood is a renewable energy source.
  2. Coal

    Yes. It takes millions of years for coal to form, so it is not considered a renewable energy source.
  3. Hydroelectric power

    No. Thanks to the water cycle, water is added to the lake above the dam, making this a renewable energy source.
  4. Wind energy

    No. Wind energy is constantly renewed by uneven heating of the Earth.

This is Halite, also known as table salt. It was formed when ancient seas dried up, leaving layers of salt behind. What kind of rock is it?.

  1. Igneous

    No. Igneous rocks formed from magma or lava. The Halite was not melted, and is not an igneous rock.
  2. Sedimentary

    Yes! Sedimentary rocks are deposited by wind, water, ice, or gravity, and they often contain fossils. Halite was deposited in large layers by water, which means that it is a sedimentary rock. Halite is also a mineral, and is one of the few rocks/minerals that we eat.
  3. Metamorphic

    No. Metamorphic rocks have been changed by heat and pressure from a different kind of rock. It is not metamorphic.
  4. Halite is not a rock.

    No. Halite is a naturally occurring solid that forms large layers in the Earth. Halite is a rock.

Which part of your body comes closest to serving the same function as a flower?

  1. Sensory organs

    No. Plants can sense their surrounds just as well without flowers.
  2. Reproductive organs

    Yes! Flowers are the reproductive organs of the plant. While most animals are either male or female, most flowers have both male (stamen) and female (pistil) reproductive organs. In this photograph, the male stamens are the green stalks with the yellow ends. The female pistil is the white structure just below the stamens.
  3. Digestive system

    No. Plants make their own food, so they do not need a digestive system.
  4. Skeletal system

    No. The stiff cell wall of a plant cell serves the same function as our skeleton.

The light area on the left side of this photo is the Milky Way. What is the Milky Way?

  1. A constellation.

    No. The Milky Way contains many more stars than a constellation.
  2. A solar system.

    No. A solar system only has one star, not a huge number of stars.
  3. A galaxy.

    Yes! Our solar system is part of the Milky Way galaxy. When we lived in the city, the lights made it difficult to see the Milky Way. Now that we live far from city lights, it is amazingly easy to see.
  4. A universe.

    No. The Milky Way is only a small part of the entire universe.

One test for identifying minerals involves rubbing the mineral on a rough tile, and looking at the color of the mark it leaves. This test is called:

  1. Cleavage

    No. Cleavage is when a mineral breaks along planes of weakness to form flat surfaces.
  2. Hardness

    No. Hardness is the resistance of a mineral to being scratched by other substances.
  3. Fracture

    No. Fracture is when a mineral breaks but does not show cleavage.
  4. Streak

    Yes. The streak test examines the color of the mineral when it is powdered by rubbing it on a rough tile or streak plate. While the actual color of a mineral can vary, it will always produce the same color streak.
