Give your fifth grader the confidence to succeed on the Arkansas ATLAS Grade 5 Science test.
This Smart Stars practice book provides five full-length, ATLAS-aligned practice tests, each with 30 items that mirror the operational length and item mix of the real ATLAS Science assessment. Every test was written by experienced educators, reviewed for accuracy, and built around the Arkansas K-12 Science Standards (NGSS-aligned) for Grade 5.
The ATLAS Science test for Grade 5 students is computer-adaptive and combines roughly 6 multi-part phenomenon-anchored “clusters” with 10 stand-alone items in one untimed session. This Smart Stars book gives each practice test the full 30-item structure (matching scored items plus a handful of unscored field-test-style items). (This includes the embedded unscored field-test items that appear on the actual ATLAS exam, so each practice test mirrors the true item count and helps your child build real-world test “endurance” for the full sitting.)
What’s inside
- Five full-length practice tests of 30 items each, with detailed Answers and Explanations after every test
- Coverage of every Grade 5 Arkansas K-12 Science Standard across the three ATLAS reporting categories: Physical Science (37.5%), Earth & Space Science (37.5%), and Life Science (25%): with Engineering integrated throughout
- Three-dimensional items (Disciplinary Core Idea + Science & Engineering Practice + Crosscutting Concept) plus six phenomenon-anchored “clusters” per test, modeled on the real ATLAS format
- Every explanation includes a labeled Strategy and Tip so students learn the underlying reasoning, not just the answer
- A combined Quick Answer Key at the back, a parent letter, and a test-taking tips section
- No-calculator, no-periodic-table, no-reference-sheet practice throughout, matching the official ATLAS Grade 5 Science policy
Topics covered
- Particle nature of matter and conservation of matter through shape changes, dissolving, and state changes
- Identifying materials by measurable properties (magnetism, conductivity, floating/sinking)
- Mixing substances: recognizing when a new substance forms (bubbling, color change, new solids)
- Gravity: the force that pulls every object on or near Earth toward Earth’s center
- Tracing food energy back to its original source in sunlight
- Plants build their bodies mostly from air and water, not from soil
- Ecosystem food webs: producers, consumers, decomposers, and how matter flows
- The Sun as a star, and why other stars look smaller and dimmer based on distance
- Patterns from Earth’s daily rotation (day/night, shadows) and yearly orbit + tilt (seasons, daylight hours, constellations)
- Earth’s four spheres (atmosphere, hydrosphere, geosphere, biosphere) and their interactions
- Distribution of Earth’s water and human impact on freshwater and the environment
- Designing fair tests with a control group and a single changing variable
Why parents and teachers choose Smart Stars
- Educator-authored. Every question is written and reviewed by classroom-experienced educators.
- Mirrors test day. Each practice test matches the official ATLAS structure, item count, and policy (no calculator, no periodic table, no reference sheet at Grade 5).
- Explanations teach the why. Every Answers and Explanations entry walks through the reasoning step by step, then provides a labeled Strategy and Tip so students learn the move, not just the answer.
- Varied across five tests. Slot positions, phenomena, contexts, and number choices rotate test-to-test so no two tests feel like the same practice run.
- Field-test items built in. Each practice test includes unscored items that mirror ATLAS’s real field-test load, building true test-day endurance.
