Every Grade 6 science expectation in the Texas Essential Knowledge and Skills (TEKS), with the free StudyQuest lessons that teach it. So far 8 of 24 expectations have a lesson. Each one is listed, covered or not, so you can see the gaps as well as the matches. This page updates as we add lessons.
How we tag: a lesson is listed only when it teaches the whole expectation. Where the TEKS say “including”, every item named is required, so a lesson that skips one is not listed. The scientific and engineering practices (6.1–6.4) and the recurring themes and concepts (6.5) run through every lesson and are not listed separately. The descriptions are short summaries; the official wording is in 19 TAC Chapter 112 (§112.26, the standards in force since the 2024–2025 school year).
6.6(A)
Compare solids, liquids and gases by particle structure, shape, volume and kinetic energy.
6.6(B)
Use physical properties to tell pure substances from solutions and heterogeneous mixtures.
6.6(C)
Classify elements on the periodic table as metals, nonmetals, metalloids or rare Earth elements.
6.6(D)
Compare the densities of substances with those of different fluids.
6.6(E)
Spot a new substance from chemical change evidence: gas, thermal energy change, precipitate, color.
6.7(A)
Explain how gravity, friction, magnetism, applied forces and normal forces act on real objects.

6.12(A)
Investigate how organisms depend on and compete for biotic and abiotic factors in an ecosystem.
No lesson yet
6.12(B)
Give examples of predation, competition and symbiosis: mutualism, parasitism and commensalism.
No lesson yet
6.12(C)
Describe how organisms, populations and communities are organized within an ecosystem.
6.13(A)
Trace how cell theory developed; organisms are made of cells, which come from existing cells.
