Based on the information given, which part of Investigation #2 is most likely the independent variable?
the type of wire
the number of coils
the size of the battery
the strength of the magnet
Which phenomenon is most likely being tested during investigation #1?
an iron nail is a natural magnet
an iron nail has to ve used to create an electromagnet
a small battery has stored magnetism that can be used to attract paper clips
wire wrapped around an iron nail attached to the poles of a battery will produce a magnetic field
Which phenomenon is most likely being tested during investigation #2?
the larger the nail is, the more magnetic Forde it will have
the battery increases the power the there are more coils in the wire
the magnetic force increases the more coils are wrapped around the nail
the wire around the nail needs to be thin to make the magnetic force stronger

Which statement best describes the continued existence of the giraffe and the okapi
the two species will likely interbreed with each other, resulting in young with characteristics from both species
the two species will likely interbreed and develop a new species with characteristics of their common ancestor
the tow species are no longer able to interbreed and both will continue to exist and reproduce in their separate environments
the two species will be in competition for natural resources with each other in a single environment, leading to the extinction of one of the species

The students decide to model how the motion of plates occurs. Which statement best describes the ability of the model to predict plate movement?
the motion of the plates cannot be modeled on the scale that is much smaller that the plates themselves
the motion of the plates cannot be modeled by the simplified the factors that contribute to plate movement
the motion of the plates can be modeled by including only the main factors that contribute to plate movement.
the motion of the plates can be modeled by including only the every factor that contribute to plate movement.
Which description correctly matches part pf the model with what it represents on Earth?
the water presents the material the Earth's crust is made of
the foam blocks represent the location the Earth's faults
the heat source represents the interior of the Earth
the large aquarium represents the structure of the Earth's plates
