What is A? A triple beam balance measures mass. A spring scale measures the force of gravity on an object. A thermometer measures temperature. A graduated cylinder measures the volume of a liquid.
Which cell part allows nutrients and other cell materials to enter and exit the cell? A. nucleus B. cell membrane C. cytoplasm D. vacuole
What is B? The cell membrane allows for materials to pass into and out of the cell.
Which biome contains the most diversity of life? A. desert B. tropical rainforest C. tundra D. grassland
What is B? Tropical rainforests contain a wide variety of organisms.
A ball is dropped from the roof of a building. As the ball falls its potential energy is converted to A. solar energy B. nuclear energy C. kinetic energy D. chemical energy
What is C? Potential energy converts to kinetic energy as an object loses height and its velocity increases.
The rotation of Earth causes A. day and night B. years C. months D. seasons
What is A? Day and night are caused by the rotation of the Earth.
Which of the following is opaque? A. frosted glass B. wax paper C. a wood door D. clear glass
What is C? A wood door absorbs and scatters the light that strikes it.
Which part of the cell contains most of the cell's genetic material? A. cell membrane B. nucleus C. cytoplasm D. mitochondria
What is B? The nucleus contains chromosomes made of genetic material.
Which sequence shows the correct order in a food chain? A. producers > carnivores>herbivores B. carnivores > producers > herbivores C. producers >herbivores > carnivores D. herbivores > carnivores > producers
What is C? The arrow represents the flow of energy from producers to herbivores and then to carnivores.
Which is an example of a chemical reaction? A. the freezing of water B. the burning of wood C. the tearing of a piece of paper D. the shattering of glass
What is B? The burning of wood creates new chemical products.
Which type of rock is produced by the cooling and solidification (hardening) of molten rock? A. igneous rock b. sedimentary rock C. metamorphic rock D. magma
What is A? Igneous rocks form from the cooling of molten rock.
Which of the following questions cannot be answered through a scientific investigation? A. How does air temperature affect air pressure? B.How does salt affect the melting point of ice? C. How does music inspire people? D. What is the relationship between elevation and air pressure?
What is C? This question is a matter of personal opinion, not science.
Jonny has blue eyes but both of his parents have brown eyes. If brown eyes is the dominant trait, describe the genitic makeup of his parents necessary for him to inherit the genes for blue eyes. A. Both parents are purebreds. B. Both parents are hybrids. C. The female parent is a purebred, and the male parent is a hybred. D. The male parent is a purebred and the female parent is a hybred.
What is B? If both Johnny's parents are hybred for eye color, then they would have a 25% chance of having a blue-eyed child.
An owl hunting a rodent is an example of which kind of relationship? A. parasite/host B. consumer/producer C. predator/prey D. consumer/decomposer
What is C? The owl is the predator, and the rodent is the prey.
Which of these is not a mixture? A. air B. milk C. pancake mix D. salt

Which from of electromagnetic radiation causes skin damange? A. visible light B. ultraviolet C. infrared D. radio waves
What is B? Ultraviolet light is harmful to the skin.
What instruments can be used to measure the volume of a small rock? A. a spring scale and a ruler B. a barometer and a thermometer C. a graduated cylinder and water D. a triple beam balance and water
What is C? A graduated cylinder and water can be used to perform the water displacement method of determining the volume of an irregularly shaped solid.
What process creates food, in the form of sugar, for plants? A. evaporation B. photosynthesis C. respiration D. oxidation
What is B? Photosynthesis creates food in the form of sugar for plants.
Which of these is not a component of soil? A. humus B. sand C. plastic D. clay
What is C? Sand, silt, clay, and humus compose soil; NOT plastic.
If two equal forces act on an object from opposite directions, the forces are said to be A. gravitional B. universal C. balanced D. unbalanced
What is C? When forces are equal and in opposite directions, they are balanced.
Which of the following is a renewable resource? A. coal B. soil C. solar energy D. natural gas
What is C? Solar energy is renewable; we can't use it up.
Which materials would be most useful if you wanted to separate a mixture of sand and sugar? A. ruler and balance B. filter paper and water C. magnet and a beaker D. graduated cylinder and a battery
What is B? Water could be mixed with sand and sugar. The sugar will dissolve in the water. Pour the mixture through the filter paper. The sand will remain in the filter paper and the sugar can be evaporated out of the sugar water.
