Middle School Chemistry Curriculum When Your School Gives You None
Chemistry Complete – Middle School is for the grades 6–8 science teacher who must teach chemistry or the matter unit with no curriculum provided. Its 20+ resources cover states of matter, mass, volume, density and solubility, physical vs chemical changes, and atoms, elements, compounds and the periodic table at a conceptual level, with inquiry tasks and answer keys.
See the chemistry curriculum →Chemistry Complete – Middle School is a no-prep chemistry curriculum for grades 6–8, starting at $149.90 for 20+ resources. For a teacher whose school provides no chemistry curriculum, it covers matter and its properties, including states of matter, mass, volume, density, solubility and physical vs chemical changes, and atoms, elements and the periodic table, including atomic structure, compounds, symbols, periodic table patterns and metals vs nonmetals.

The real problem
Where middle school chemistry goes wrong without a plan
Middle school chemistry asks students to believe in things they cannot see. Atoms, elements and compounds are invisible, and without a curriculum that builds up to them, the periodic table becomes a poster students are asked to memorize. They learn that sodium is Na and never understand why the table is arranged the way it is or what makes a metal different from a nonmetal. The better path starts with what students can observe: matter has mass and takes up space, it exists as solid, liquid and gas, some things dissolve and others do not, and some changes can be reversed while others produce something new. Density is the classic sticking point here. Students confuse heavy with dense, and fixing that needs careful tasks with real measurements or data. Only after those observable properties make sense do atoms and elements become a useful explanation rather than a fact to accept. Building that sequence alone, with safe classroom activities, clear diagrams of atomic structure at a level twelve-year-olds can follow, and answer keys for every task, is a lot to ask of one teacher who may also be covering life or physical science.
Why it fits
How the curriculum fits the gap
It moves from observable properties of matter to the atomic ideas that explain them, which is the order students can follow.
- States of matter lessons start with what students can see and describe.
- Mass, volume and density tasks address the common heavy-versus-dense confusion directly.
- Solubility and physical vs chemical changes give students clear criteria for classifying what happens.
- Atomic structure at a conceptual level explains matter without overwhelming younger students.
- Periodic table patterns and metals vs nonmetals turn the table into a tool, not a memorization chart.
- Inquiry practices keep observation and evidence at the center, even with limited lab supplies.
Getting started
Your first two weeks with it
A suggested starting order. The curriculum provides sequenced units but no dates, so pace it to your class.
- Start with states of matterOpen with solids, liquids and gases. Ask students to sort familiar substances and explain their reasoning, which shows you what ideas they bring before any vocabulary is introduced.
- Measure mass and volumeUse the mass and volume tasks with whatever scales and measuring containers you have. Real numbers make density much easier to grasp than a definition on a slide.
- Tackle density head onRun the density lessons before moving on. Asking whether a large block of wood or a small piece of metal is denser exposes the heavy-versus-dense confusion so you can correct it.
- Classify changes with evidenceTeach physical vs chemical changes using clear criteria such as new substances forming. Students practice using evidence to decide, which is the core habit of chemistry.
- Introduce atoms as an explanationOnly then move to atoms and elements. Frame atomic structure as the answer to why matter behaves as students have observed, and the periodic table follows naturally.
Which version
Which version, and when to combine
The $149.90 version includes all 20+ resources, a focused set on matter and the periodic table. If chemistry is one unit within a broader physical science course, it may be exactly the right size. If you need a full year, consider pairing it with Physics Complete – Middle School, which covers motion, forces and energy; code TEACHMORE15 gives 15% off two or more Complete Curriculum packages. The $189.90 version adds Teach-Life-Balance, a digital course with a planner, guides and templates for teacher workload, but no chemistry content.
Honest limits
What it leaves to you
No chemicals, glassware or lab equipment are included, and any hands-on activity uses materials you supply and your school's safety rules. With 20+ resources it is a focused unit set, not a full high school chemistry course; check the product page listing against your requirements. Its inquiry practices are not an endorsement of any standards, so compare it with your state or district science requirements. Team use by other science teachers needs a short message to Teach Lessons beforehand. You can exchange it within 7 days for store credit of equal value if it is not a fit; no cash is returned.
Good to know
Frequently asked questions
Does it meet NGSS or my state's science standards?
It includes inquiry practices and covers matter and atoms at a middle school level, but it is not endorsed, adopted or officially matched to NGSS or any state's standards. Compare the units with your own state science standards and identify any topics, such as chemical reactions in more depth, that you need to add.
Is it enough for a full year of chemistry?
Probably not on its own. With 20+ resources it fits a semester, a chemistry unit within physical science, or a focused block. For a full year, many teachers combine it with Physics Complete – Middle School or other science material. Check the product page listing to judge how far it stretches for your schedule.
How deep does the atomic content go?
Atomic structure is taught at a conceptual level suitable for grades 6–8, along with elements, compounds, symbols, periodic table patterns and metals vs nonmetals. It does not go into the mathematical detail of high school chemistry, which suits middle schoolers who are meeting atoms for the first time.
Will it work in a room with no lab benches?
Yes, for much of it. Many tasks rely on observation, data, diagrams and classification. Density and mass work go better with a scale and measuring containers, but you can use provided data where equipment is missing. Any hands-on activity should follow your school's safety rules.
How does it handle different ability levels?
Differentiated worksheets are part of the set, written for mixed-ability groups. Students who need support can focus on classifying states and changes, while stronger students take on density calculations and periodic table patterns in more depth. Both groups still work on the same topic, which keeps class discussion shared.
When can I use it?
Right away. After purchase a download link arrives by email, and the files also sit in your customer account under Orders. Everything works for print or digital classrooms, so the states of matter lesson can start this week using ordinary classroom objects, water and air as examples.
