Sample SC READY Science Grade 4 Practice Questions

Try these sample questions to test your SC READY Science Grade 4 exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which of the following is the primary source of light and heat energy for Earth?
A.The Moon
B.The Sun
C.Volcanoes
D.Electrical power grids
Explanation: The Sun is a star that releases immense amounts of energy, serving as the primary source of light and heat for Earth's weather, climate, and living organisms.
2A student places a cup of hot cocoa on a kitchen table. After 30 minutes, the cocoa feels cool. How did thermal energy move?
A.Thermal energy moved from the cool room air into the hot cocoa.
B.Thermal energy moved from the hot cocoa into the cooler surrounding air.
C.Thermal energy disappeared completely from the cup.
D.Cold energy moved from the table directly into the cocoa.
Explanation: Heat (thermal energy) naturally flows from warmer objects to cooler surroundings until temperatures balance out.
3When you turn on a battery-powered flashlight, what energy transformation takes place?
A.Chemical energy -> Electrical energy -> Light and Heat energy
B.Light energy -> Electrical energy -> Sound energy
C.Thermal energy -> Chemical energy -> Mechanical energy
D.Electrical energy -> Sound energy -> Chemical energy
Explanation: Batteries store chemical energy, which converts into electrical energy when connected in a circuit. This electrical energy then powers the bulb to produce light and thermal (heat) energy.
4What must occur for a bell to produce sound energy?
A.The bell must melt.
B.The bell must vibrate.
C.The bell must absorb light.
D.The bell must be insulated with rubber.
Explanation: Sound is created when an object vibrates rapidly back and forth, pushing air molecules to create sound waves.
5Solar panels installed on school roofs absorb energy from sunlight to power lights inside the school. Which energy transformation occurs?
A.Sound energy to mechanical energy
B.Light energy to electrical energy
C.Electrical energy to chemical energy
D.Heat energy to sound energy
Explanation: Photovoltaic cells in solar panels capture light energy from the Sun and convert it directly into electrical energy.
6A student builds a simple circuit with a battery, wires, and a light bulb. The bulb does not light up. What is the MOST LIKELY reason?
A.The circuit path is completely closed.
B.The circuit path has a gap or is open.
C.The wires are made of copper metal.
D.The battery is brand new.
Explanation: Electric current requires a continuous, unbroken path (a closed circuit) to flow. An open circuit has a gap that stops the flow of electricity.
7Why are electrical wires in homes typically covered with a plastic coating?
A.Plastic is a good conductor that speeds up electricity.
B.Plastic is an insulator that prevents electric shocks and short circuits.
C.Plastic increases the weight of the wire to keep it steady.
D.Plastic converts electricity into magnetic force.
Explanation: Plastic is an electrical insulator, meaning electric charges cannot easily flow through it. The coating safely seals the electric current inside the metal wire.
8Which component in a simple circuit acts as the energy source?
A.The light bulb
B.The switch
C.The battery
D.The plastic wire clip
Explanation: The battery provides the electrical energy (voltage) needed to push electric current through the circuit.
9What is the function of a switch in an electrical circuit?
A.To produce electrical energy for the circuit
B.To turn electrical energy into light energy
C.To open or close the circuit path safely
D.To increase the voltage of the battery
Explanation: A switch allows a user to open (stop current flow) or close (allow current flow) an electrical circuit.
10Which material would be BEST to test as an electrical insulator in a classroom circuit experiment?
A.Copper penny
B.Rubber eraser
C.Aluminum foil strip
D.Iron nail
Explanation: Rubber is a non-metallic material that resists the flow of electricity, making it an excellent insulator.

About the SC READY Science Grade 4 Exam

The South Carolina College- and Career-Ready Assessment (SC READY) in Science evaluates Grade 4 students on statewide academic standards. The test assesses scientific inquiry, physical science concepts (energy, light, sound, circuits), life science systems (plant/animal structures, food webs, adaptations), and Earth/space science processes (weather, water cycle, rocks, lunar phases).

Assessment

One untimed online section of 45 items assessing the South Carolina College- and Career-Ready Science Standards 2021: Energy 12-16 items; Waves 9-12; Organisms and the Environment 12-16; Earth Processes and Features 9-12. The test includes three stimulus sets that each provide context for three related items, plus 7 embedded field-test items. Depth of Knowledge ranges are DOK 1 at 0-10%, DOK 2 at 60-70%, and DOK 3 at 25-30%.

Time Limit

Not timed. SCDE publishes an approximate 90 minutes for scheduling only. The test is one section given in a single day.

Passing Score

No pass mark is set. SC READY results are reported in four performance levels: Does Not Meet Expectations, Approaches Expectations, Meets Expectations, and Exceeds Expectations.

Exam Fee

No fee (South Carolina Department of Education (SCDE); online delivery on DRC INSIGHT (Data Recognition Corporation))
