Sample KSA Science Grade 4 Practice Questions

Try these sample questions to test your KSA 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.

1A student rolls a toy car down a short wooden ramp and then down a steeper wooden ramp. What happens to the car's speed and kinetic energy when it rolls down the steeper ramp?
A.The car moves faster and has more kinetic energy.
B.The car moves slower and has more kinetic energy.
C.The car moves faster but has less kinetic energy.
D.The car's speed and kinetic energy remain unchanged.
Explanation: As the incline of a ramp increases, gravity accelerates the car more, increasing its speed. Because kinetic energy depends directly on an object's speed, moving faster means the car possesses greater kinetic energy.
2A heavy bowling ball and a light tennis ball are both rolling across a gym floor at the exact same speed. Which statement correctly compares their kinetic energy?
A.The bowling ball has more kinetic energy because it has greater mass.
B.The tennis ball has more kinetic energy because it is smaller.
C.Both balls have the same kinetic energy because they move at the same speed.
D.Neither ball has kinetic energy while rolling across a flat floor.
Explanation: Kinetic energy depends on both speed and mass. When two objects move at the same speed, the object with more mass (the bowling ball) has greater kinetic energy.
3A metal spoon at room temperature is placed into a bowl of hot vegetable soup. What energy transfer occurs over time?
A.Thermal energy transfers from the hot soup into the metal spoon.
B.Thermal energy transfers from the metal spoon into the hot soup.
C.Cold energy transfers from the spoon into the hot soup.
D.Light energy transfers from the soup into the spoon.
Explanation: Thermal energy (heat) naturally flows from a warmer object (the hot soup) to a cooler object (the room-temperature metal spoon) until thermal equilibrium is approached.
4When a student strikes a drum, the drumhead vibrates rapidly. How does sound energy travel from the drum to a listener's ear across the room?
A.The drumhead vibrates air particles, passing sound energy outward as waves.
B.Air particles travel in a straight line from the drum directly into the listener's ear.
C.Electrical currents flow through the air from the drum to the ear.
D.Heat rays carry the sound vibrations through empty space.
Explanation: Vibrations of the drumhead bump into nearby air particles, creating high and low pressure regions (sound waves) that transfer acoustic energy through the air without moving individual air particles across the room.
5A glass marble rolling along a track hits a stationary plastic marble. What happens during this collision?
A.Energy is transferred from the moving glass marble to the stationary plastic marble.
B.Energy is created out of nothing at the point of contact.
C.Both marbles immediately lose all of their energy and stay completely still.
D.The plastic marble transfers speed to the glass marble before they touch.
Explanation: During a collision, energy is transferred from the moving object (glass marble) to the resting object (plastic marble), causing the plastic marble to begin moving and the glass marble to slow down.
6A battery-powered flashlight is turned on. Which sequence shows the energy transformations taking place inside the flashlight?
A.Chemical energy -> Electrical energy -> Light and Heat energy
B.Light energy -> Chemical energy -> Sound energy
C.Thermal energy -> Motion energy -> Electrical energy
D.Sound energy -> Electrical energy -> Chemical energy
Explanation: Batteries store chemical energy. When the circuit closes, chemical energy transforms into electrical energy flowing through wires, which the lightbulb transforms into light and thermal (heat) energy.
7A student plucks a stretched rubber band. What change causes the rubber band to produce a higher-pitched sound?
A.Stretching the rubber band tighter so it vibrates more rapidly.
B.Loosening the rubber band so it vibrates more slowly.
C.Plucking the rubber band with less force.
D.Making the rubber band thicker and longer.
Explanation: Higher pitch corresponds to higher frequency (faster vibrations). Stretching a rubber band tighter causes it to vibrate faster when plucked, producing a higher pitch.
8Which diagram path correctly explains how a person can see an apple sitting on a table in a lighted room?
A.Light source -> Apple -> Human eye
B.Human eye -> Apple -> Light source
C.Apple -> Light source -> Human eye
D.Human eye -> Light source -> Apple
Explanation: Vision occurs when light emitted by a light source strikes an object (the apple) and reflects off its surface into the human eye, where sensory cells detect it.
9Two students on opposite sides of a dark playground use flashlights to communicate using short and long pulses of light. What does this activity demonstrate?
A.Using light patterns to transfer information over a distance.
B.Using sound vibrations to move objects across space.
C.Converting electrical currents directly into mechanical work.
D.Reflecting shadows to increase energy production.
Explanation: Transmitting encoded pulses of light (such as Morse code) relies on light patterns to carry messages and information across distances.
10A bicycle rider traveling at 15 miles per hour requires a greater distance to come to a complete stop than when traveling at 5 miles per hour. Why?
A.The bicycle has much more kinetic energy at higher speed, requiring more force and distance to stop.
B.The bicycle has less mass when moving faster, making brakes less effective.
C.Friction between tires and ground vanishes at higher speeds.
D.Gravity pulls sideways on the bicycle when speed increases.
Explanation: At 15 mph, the bicycle has significantly more kinetic energy than at 5 mph. Stopping requires removing all kinetic energy through braking friction, which takes a longer distance at higher speeds.

About the KSA Science Grade 4 Exam

Kentucky Summative Assessment Science — Grade 4 measures the Kentucky Academic Standards for Science. This local 100-question bank is an English-language MCQ study adaptation. It does not simulate multi-part phenomena, investigations, scientific modeling, or performance tasks. It is not an official translation, format simulation, or substitute for the KSA.

Assessment

The official assessment is administered online at school and uses varied item types built around three-dimensional, phenomenon-based scientific reasoning and engineering design. No separate assignment, oral examination, practical examination, or case study is required; extended-response and technology-enhanced items remain part of the official assessment.

Time Limit

90 KDE-recommended minutes across 1 part; this is recommended testing time rather than a candidate-selected appointment limit.

Passing Score

KSA is not a certification exam and has no single pass mark. Results use four performance levels: Novice, Apprentice, Proficient, and Distinguished.

Exam Fee

No separate student fee; Kentucky's public-school accountability assessment is state funded. (Kentucky Department of Education (KDE))
