1Two teams are playing tug-of-war. Team A pulls to the left with a force of 50 newtons. Team B pulls to the right with a force of 50 newtons. The rope does not move. Which statement best describes the forces on the rope?

A.The forces are balanced, so the rope stays in place.

B.The forces are unbalanced, so the rope will speed up.

C.The rope does not move because there are no forces acting on it.

D.The rope will move toward the team that pulls last.

Explanation: When two equal forces pull in opposite directions, the forces are balanced and the net force is zero, so the rope does not move.

2A student brings a magnet near several objects. Which object will the magnet attract?

A.An iron nail

B.A plastic spoon

C.A wooden pencil

D.A glass marble

Explanation: Magnets attract materials that contain iron (and other magnetic metals like nickel and cobalt). Iron is a magnetic metal, so the iron nail is attracted to the magnet.

3On a dry winter day, a student rubs a balloon against her hair. Her hair then stands up and is pulled toward the balloon. What is the most likely cause?

A.Static electric charge built up on the balloon and attracts her hair.

B.The balloon becomes magnetic and pulls on her hair.

C.Gravity between the balloon and her hair gets stronger.

D.The balloon gets heavier and pushes the hair upward.

Explanation: Rubbing the balloon against hair transfers electric charge, building up static electricity. The charged balloon can then attract lightweight objects like strands of hair.

4A student pushes a swing. After the student lets go, the swing moves back and forth, going a little less high each time. Why does the swing eventually come to a stop?

A.Friction and air resistance transfer the swing's energy to other forms.

B.The swing runs out of force and has to be pushed again.

C.Gravity pulls the swing down only when it is moving.

D.The swing stops because no energy was ever given to it.

Explanation: As the swing moves, friction at the chains and air resistance transfer its motion energy into heat and sound, so the swing loses energy and gradually stops.

5A cart rolls along a track and bumps into a stationary block of wood. The block slides forward after the collision. What best explains what happened?

A.Energy was transferred from the moving cart to the block during the collision.

B.The block created its own energy to start moving.

C.The cart's energy disappeared completely when it hit the block.

D.The block was pulled forward by gravity from the cart.

Explanation: In a collision, a moving object can transfer some of its energy of motion to another object, causing that object to move.

6A ball is released from rest at the top of a ramp. As it rolls down, it speeds up. What is happening to the ball's energy as it rolls down the ramp?

A.Stored energy due to height is changing into energy of motion.

B.Energy of motion is changing into stored energy due to height.

C.The ball is losing all of its energy as it rolls down.

D.No energy change is occurring while the ball rolls.

Explanation: At the top, the ball has stored (potential) energy because of its height. As it rolls down, that stored energy is converted into energy of motion (kinetic energy), so it speeds up.

7A flashlight contains batteries and a bulb. When the switch is pressed, the bulb lights up. Which best describes the energy conversion in the flashlight?

A.Chemical energy in the batteries is changed into electrical energy and then into light and heat.

B.Light energy is changed into chemical energy inside the bulb.

C.Sound energy from pressing the switch becomes light energy.

D.Heat energy from your hand becomes light energy in the bulb.

Explanation: A flashlight converts stored chemical energy in the batteries into electrical energy, which the bulb then converts into light (and some heat).

8A student makes two sounds with the same pitch. One sound is much louder than the other. Compared with the quieter sound, how does the louder sound's wave look?

A.The louder sound has a larger amplitude.

B.The louder sound has a longer wavelength.

C.The louder sound has a higher frequency.

D.The louder sound has a shorter wavelength.

Explanation: Loudness is related to the amplitude (height) of a sound wave. A louder sound has a larger amplitude, while a quieter sound has a smaller amplitude. Since the pitch is the same, the wavelength and frequency do not change.

9A student draws a wave and labels the distance between two neighboring crests. Which property of the wave is this distance?

A.Wavelength

B.Amplitude

C.Frequency

D.Speed

Explanation: Wavelength is the distance between two neighboring crests (or two neighboring troughs) of a wave.

10A cell phone sends a signal to a tower so a call can be made. The signal travels through the air as a wave. What is the main way waves are used in this situation?

A.Waves are used to send information from one place to another.

B.Waves are used to heat the air around the phone.

C.Waves are used to push objects out of the way.

D.Waves are used to create electricity inside the phone.

Explanation: Waves can carry information from one place to another. Cell phones use electromagnetic waves to send voice and data signals to towers without using wires.

About the North Dakota A+ Science Grade 4 Exam

The North Dakota A+ Summative Science assessment at Grade 4 measures proficiency on the 2023 North Dakota Science Content Standards across Physical Science, Earth & Space Science, and Life Science. It is administered online through TestNav in spring, replacing the former NDSA beginning Spring 2025. This 100-question practice bank uses four-option MCQs as an English-language study adaptation.

Assessment

Online criterion-referenced assessment delivered through TestNav; phenomena-based item clusters, selected-response, and technology-enhanced items across three reporting categories. This local bank contains 100 English four-option practice MCQs, including scenario-based items.

Time Limit

Untimed; 2025 average about 81 minutes (25th-75th percentile 56-97 minutes)

Passing Score

Four performance levels: Level 1 Novice, Level 2 Approaching Proficient, Level 3 Proficient, Level 4 Advanced. Level 3 and above denotes proficiency. Scale scores range 850-1150 (Grade 4: Novice 850-972, Approaching Proficient 973-1009, Proficient 1010-1051, Advanced 1052-1150).

North Dakota A+ Science Grade 4 Study Tips from Top Performers

1Connect a force to its effect: pushes and pulls can change an object's speed or direction.

2Trace energy as it moves and changes form, and notice that some energy is always transferred away as heat.

3For weather and climate, distinguish daily weather (short-term conditions) from climate (long-term patterns).

4Relate an organism's structures to their functions (roots take in water; teeth break down food).

5Read data tables and simple graphs carefully before choosing an answer in scenario items.
