Sample WY-TOPP Science Grade 10 Practice Questions

Try these sample questions to test your WY-TOPP Science Grade 10 exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1An atom of neutral carbon-12 has an atomic number of 6. How many protons, neutrons, and electrons does it contain?
A.6 protons, 6 neutrons, 6 electrons
B.6 protons, 12 neutrons, 6 electrons
C.12 protons, 6 neutrons, 12 electrons
D.6 protons, 0 neutrons, 6 electrons
Explanation: The atomic number (6) defines the number of protons. In a neutral atom, electrons equal protons (6). The mass number (12) minus atomic number (6) gives 6 neutrons.
2Which state of matter has a definite volume but takes the shape of its container?
A.Gas
B.Liquid
C.Solid
D.Plasma
Explanation: Liquids have fixed volume because intermolecular forces keep molecules close, but lack a fixed shape, allowing them to flow and conform to their container.
3A laboratory cart travels a distance of 20 meters in 4 seconds at constant speed. What is its speed?
A.80 m/s
B.5 m/s
C.16 m/s
D.0.2 m/s
Explanation: Speed is calculated as distance divided by time: v = d / t = 20 m / 4 s = 5 m/s.
4A boulder resting at the top of a steep cliff possesses primarily which form of energy?
A.Kinetic energy
B.Gravitational potential energy
C.Chemical energy
D.Thermal energy
Explanation: Gravitational potential energy is stored energy due to an object's elevated position within a gravitational field (PE = mgh).
5According to Newton's First Law of Motion, an object moving in deep space at constant velocity will continue moving at that velocity unless acted upon by:
A.An unbalanced external force
B.A balanced force pair
C.Internal thermal energy
D.Gravitational waves
Explanation: Newton's First Law (Law of Inertia) states an object maintains constant velocity unless acted upon by a net unbalanced external force.
6A solution has a pH of 2. How should this solution be classified?
A.Strongly basic
B.Neutral
C.Strongly acidic
D.Weakly basic
Explanation: The pH scale ranges from 0 to 14. Solutions with pH less than 7 are acidic, and a pH of 2 represents a high concentration of H+ ions (strongly acidic).
7What term describes the number of wave crests that pass a fixed point per second?
A.Wavelength
B.Amplitude
C.Frequency
D.Wave speed
Explanation: Frequency is the number of complete wave cycles or crests passing a reference point per unit of time, measured in Hertz (Hz).
8Elements in the same vertical column (group) of the periodic table share similar chemical properties primarily because they have:
A.The same number of valence electrons
B.The same total number of neutrons
C.Identical atomic masses
D.The same number of electron shells
Explanation: Elements in the same periodic group have the same number of outer-shell valence electrons, governing their chemical reactivity and bonding behavior.
9What type of chemical bond is formed when electrons are transferred from a metal atom to a nonmetal atom?
A.Covalent bond
B.Ionic bond
C.Metallic bond
D.Hydrogen bond
Explanation: Ionic bonds form through the electrostatic attraction between oppositely charged ions created when electrons transfer from a metal to a nonmetal.
10When 10 grams of reactant A completely reacts with 15 grams of reactant B in a closed container, what is the total mass of the products formed?
A.5 grams
B.10 grams
C.25 grams
D.150 grams
Explanation: The Law of Conservation of Mass dictates that mass cannot be created or destroyed in a chemical reaction. Total product mass equals total reactant mass (10 g + 15 g = 25 g).

About the WY-TOPP Science Grade 10 Exam

The WY-TOPP (Wyoming Test of Proficiency and Progress) Summative Science assessment for Grade 10 is Wyoming's required statewide high school science test, administered by the Wyoming Department of Education during the spring window (April 14 - May 8 in 2026). It is built on the 2026+ Science Assessment Blueprint approved by the State Board of Education on September 19, 2024 and aligned to the reduced 2023 Wyoming Science Content and Performance Standards, operational on WY-TOPP from the 2025-26 school year. The blueprint weights Physical Science at 33-38%, Life Science at 33-38%, and Earth and Space Science at 26-31%, with engineering and design embedded across all three strands. Results are reported as a scale score and one of four performance levels, with Proficient beginning at 1001. Because the science standards were reduced, WDE ran a new data-validation and standard-setting process for spring 2026 and released official science results in fall 2026; individual student reports for science no longer include domain-level reporting. Please note: this practice bank is an English-language multiple-choice study adaptation created by OpenExamPrep, not an official test form.
