Questions in the test's style, each with the answer and an explanation. Open the answer once your child has tried the question.
Question 1 · Grade 8 Science · Standard MS-LS4-1
Fossils of the same species found on separate continents support the theory of —
- A.Spontaneous generation
- B.Continental drift
- C.Cell theory
- D.Gravity
Show the answer and explanation
Answer: B. Continental drift
Identical fossils on different continents = those landmasses were once connected and drifted apart over millions of years.
Question 2 · Grade 5 Science · Standard 5-ESS2-1
Most of Earth's fresh water is found in —
- A.Oceans
- B.Rivers
- C.Glaciers and ice caps
- D.Underground wells
Show the answer and explanation
Answer: C. Glaciers and ice caps
About 69% of Earth's freshwater is locked in glaciers and ice caps. Rivers and lakes hold less than 1%.
About the LEAP 2025 Grade 8 Science Test
Grade 8 science is the last middle-school LEAP science test, so it carries weight as a science checkpoint before high school (in 2026-27 every grade 3-8 takes LEAP science; grade-band tests begin in 2028-29). And science had the lowest Mastery rate of the four LEAP subjects: statewide, 31% of students in grades 3-8 reached Mastery or above in 2026. The scoring frame holds — "Mastery" is the target, "Basic" is below it.
The test measures the Louisiana Student Standards for Science — three-dimensional and phenomenon-based — across Physical, Life, and Earth & Space Science, assessed through item sets, a task set, and stand-alone items. Grade-8 content covers matter and energy, cells and heredity, natural selection, and Earth's systems and history.
Statewide in 2026, 31% of Louisiana students (grades 3-8) reached Mastery or above in science, up from 29% in 2025.
LEAP science is given online in three 65-minute sessions.
Mastery + Advanced = on grade level. The lowest of Louisiana's four LEAP subjects in 2026 — below ELA (43%), math (34%), and social studies (33%). 'Basic' is BELOW Mastery.

What's On The LEAP 2025 Grade 8 Science Test
Grade 8 science on LEAP is three-dimensional and phenomenon-based, covering Physical, Life, and Earth & Space Science. LDOE reports it in three practice-based categories: Investigate, Evaluate, and Reason Scientifically (the extended-response task counts toward the overall score only).
| Reporting Category | What's Tested |
|---|---|
| Investigate | Asking questions, defining problems, and planning investigations across physical, life, and Earth & space science. |
| Evaluate | Analyzing and interpreting data, using math and computational thinking, and arguing from evidence — for example, about natural selection or human impacts on Earth. |
| Reason Scientifically | Developing and using models, constructing explanations, and designing solutions — for example, modeling atoms and molecules or Earth's rock cycle. |
Test Format — What Your Child Will See
- ●Science had the lowest Mastery+ rate of the four LEAP subjects in 2026 (31%).
- ●The test is phenomenon-based — reasoning about scenarios, not just recall.
- ●"Mastery" is the target; "Basic" is below it.
What Louisiana Parents Should Know About Grade 8 Science
- 1
Cover all three areas — physical, life, and Earth & space science all appear on the grade-8 test.
- 2
Practice reasoning about scenarios and data — LEAP science is phenomenon-based, not just recall.
- 3
Practice the extended response — the task set ends with a longer written answer that pulls the whole scenario together.
- 4
Treat science as a real target — it had the lowest Mastery+ rate of the four LEAP subjects in 2026 (31%), so focused review pays off.
LEAP 2025 Grade 8 Science — Frequently Asked Questions
Why are Louisiana 8th grade LEAP science scores low?
Science had the lowest Mastery rate of the four LEAP subjects in 2026 — 31% of grades 3-8 students. The test is phenomenon-based (reasoning about real scenarios), not a vocabulary quiz. Targeted review helps.
What is on the 8th grade LEAP science test?
The Louisiana Student Standards for Science across Physical Science (matter and energy), Life Science (cells, heredity, natural selection), and Earth & Space Science (Earth's systems, history, and human impacts), assessed through item sets, a task set, and stand-alone items.
Does Louisiana test science in every grade?
Yes, for now. In 2026-27, every student in grades 3-8 takes a grade-specific LEAP science test. BESE approved moving to grade-band science tests starting in 2028-29.
What does 'Mastery' mean on LEAP?
Mastery is the on-grade-level target; 'Basic' is BELOW it.
When is the LEAP test in 2027?
Online LEAP testing runs April 1 – May 12, 2027; your school sets its exact dates inside that window.
