PS Physical Sciences
- 8.PS1.1Particles, Atoms, Elements, and CompoundsUse a model to understand that atoms are a system composed of a positively charged nucleus surrounded by one or more negatively charged particles called electrons
- 8.PS1.2Particles, Atoms, Elements, and CompoundsDevelop a model to explain how the light coming from distant stars and the formation of heavier atoms is the result of changes in the composition of the nucleus of the atom and the energy released during the process of nuclear fusion
- 8.PS2.1Forces, Motion, and InteractionsConduct an investigation to provide evidence that the size of force fields (electric and magnetic) depends on the magnitudes of the charges, current, or magnetic strengths involved and the distances between interacting objects
- 8.PS2.2Magnets, Electricity, and CircuitsAsk scientific questions about data to determine how manipulating variables can increase or diminish the electric current and magnetic field strength in electromagnets, generators, and electric motors
- 8.PS2.3Gravity and Object MotionConstruct an argument using evidence to support the claim that gravitational interactions in a large-scale system are attractive and depend on the masses of and distance between interacting objects

- 8.PS2.5Forces, Motion, and InteractionsPlan and conduct an investigation to provide evidence that the change in an object's motion depends on the sum of the forces on the object and the mass of the object
- 8.PS2.6Forces, Motion, and InteractionsEvaluate and interpret that for every force exerted on an object there is an equal force exerted in the opposite direction
- 8.PS4.1Material Properties and UsesDevelop and use models to represent the basic properties of waves in a system including frequency, amplitude, wavelength, and speed

Does Tennessee test science in grade 8?
Yes. Tennessee students take TCAP Science in grade 8. It is the state's eighth-grade science assessment.
Which standards does grade 8 science in Tennessee follow?
Tennessee follows the Tennessee Academic Standards for Science, published by the Tennessee Department of Education. All 24 of this grade's standards are listed further down the page with their official codes.
How long are the practice tests?
Each of the six practice tests has 40 questions and a 70-minute timer. The timer auto-submits at zero and you get your score, a breakdown by science area, and a written explanation for every question.
Is any of this free?
Yes, every practice test, quiz, and flashcard set on this page is free and needs no login. Your progress is saved in your own browser and nowhere else.
What is the fastest way to use this page?
Take practice test 1 cold. Look at the topic breakdown, pick the weakest science area, and do that skill quiz. Then read the quick review for that area and come back for practice test 2.
