Which is the BEST comparison of static electricity and electric current?
Static electricity flows through wires, while electric current jumps across wires.
Static electricity involves open circuits, while electric current involves closed circuits.
Static electricty involves build-up of electrons in an object, while electric current involves the flow of electrons through wires.
Static electricity begins with objects that have a negative charge, while electric current begins with objects that have a positive charge.
Which statement about vertebrates is true?
Vertebrates have skeletons.
Vertebrates live only on land.
Most animals are vertebrates.

Which statement describes how deposition builds up the surface of a floodplain?
Lava flows from a volcano and piles up.
Rainwater seeps into the ground and freezes.
A river flows over its banks and slows down.
A river slows down as it flows into the ocean.
A student carries out an investigation to observe a change of state in water. She records her observations and data in the diagram.
Which argument is supported by the student's observations?
A decrease in temperature makes water change from a liquid to a solid.
A decrease in temperature makes water change from a solid to a liquid.
An increase in temperature makes water change from a liquid to a solid.
An increase in temperature makes water change from a solid to a liquid.
A scientist plans to make models of three kinds of cells: oak leaf, squirrel muscle, and fern leaf.
Which model(s) will have organelles that contain chlorophyll?
only the fern leaf cell
only the squirrel muscle cell
the fern leaf and the oak leaf cell
the oak leaf cell, the squirrel muscle cell, and they fern leaf cell

A student wants to increase the strength of an electromagent. Which of these is a way to make the electromagnet stronger?
replacing the iron core with a copper core
replacing the copper wire with plastic wire
wrapping the wire around the iron core fewer times
increasing the electric current flowing through the wire
A student designs and builds the circuit shown in the picture.
Which part of the circuit converts electrical energy into another form of energy?
wire
switch
battery
light bulb
Which statement explains why the light bulb is not lit?
The battery is dead, so there is no electrical source.
The switch is open, so electric current cannot flow through the circuit.
The light bulb requires more electrical energy than the battery can provide.
The wires are not conductors, so electric current cannot flow through the circuit.
The picture shows a student observing part of a living thing.
Which claim could the student support with evidence from his observation?
Animal cells and plant cells have different organelles
A plant cell is too small to be seen without using a microscope
An animal cell is too small to be seen without using a microscope
The cell membrane of an animal cell is thinner than the cell membrane of a plant cell
A student draws two plants.
How do the plants compare? Select THREE choices.
They are both coniferous plants
They both have stems and leaves
They reproduce in different ways
They get energy in different ways
They both use photosynthesis to make food
