Decomposers break down dead organisms and return nutrients to the ecosystem. An an example of a decomposer is a: mushroom rose horse tiger Correct Wrong Mushrooms, other fungi, and bacteria are decomposers. Plants, such as a rose, are producers. Horses and tigers and other animals are consumers. 2. You are given a 2-liter bottle of Cola. 2 liters is a measure of: volume mass length density Correct Wrong A liter is a unit of volume. Mass may be measured in gram or pounds. Length or distance is measured in units like meters, inches, or miles. Density is mass per volume, so it could have a unit like grams per liter. 3. Galileo and Copernicus believed this was the center of the solar system and everything else revolved around it. Sun Moon Earth Jupiter Correct Wrong Galileo and Copernicus believed the Earth revolved around the Sun. Ptolemy and most other earlier astronomers believed the Earth was the center of the Universe. 4. An instrument that measures precipitation is a: barometer rain gauge thermometer anemometer Correct Wrong A rain gauge records precipitation, such as snow and rain. A barometer is an instrument that measures pressure. Thermometers measure temperature. An anemometer measures wind speed. 5. Which of the following is a nonrenewable source of energy? wind power coal solar power water power or hydropower Correct Wrong Solar, wind, and water power are based on renewable energy sources. Because coal takes millions of years to form from organic matter, it's considered nonrenewable. 6. Ferns and mosses reproduce using: spores seeds fruit nuts Correct Wrong Spores and seeds can give rise to new plants. A nut is a type of seed. Fruit encapsulates a seed, but can't grow a new plant on its own. 7. Electricity and heat move easily through this material: plastic air insulator conductor Correct Wrong Energy like heat and electricity can pass through a conductor, but not an insulator. Plastic and air are both examples of thermal and electrical insulators. Metals are good conductors. 8. Objects in motion have which type of energy? kinetic potential nuclear electrical Correct Wrong The energy of motion is called kinetic energy. Energy of position is potential energy. Nuclear energy involves reactions in the atomic nucleus, while electrical energy comes from the movement of charged particles. 9. Wires are made from materials that conduct electricity well. Which of the following materials could you use as a wire? ice sugar wool copper Correct Wrong Copper and other metals can conduct electricity. Ice, sugar, and wool would likely melt or burn before they'd conduct, so they would be poor choices for wires. 10. Thin, wispy clouds high in the sky are: cumulonimbus clouds stratus clouds cirrus clouds cumulus clouds Correct Wrong Cirrus clouds are the high, wispy ones. Cumulus clouds are the fluffy ones that resemble cotton balls in the sky. Stratus clouds are low and flat. Cumulonimbus clouds tower high into the sky and may produce thunderstorms. 4th Grade Science Quiz You got: % Correct. Still Stuck in 4th Grade Science tuh tuh / Getty Images Nice try!
