28.1 Foundations of Scientific Learning

28.1 Foundations of Scientific Learning

PECT lens: Objective 0013.1 (Module 3 — Mathematics, Science, and Health, 100% of Module 3 together with 0012 and 0014) tests the foundations of scientific learning — Pearson names the importance of inquiry and process skills and reliance on verifiable evidence — and how scientific learning and thinking affects and interacts with children's development and learning. Module 3 is 45 selected-response items in 90 minutes, with an on-screen calculator and the acronyms glossary. This descriptor is about how children learn to do science, not about dumping life, ecology, physical, or earth content (those are 0013.5–0013.8).

Science in PreK–4 is not a miniature high-school survey. It is how young children make sense of the natural and designed world by noticing, asking, trying, and checking. Pennsylvania teachers plan that work from STEELS — Science, Technology & Engineering, Environmental Literacy & Sustainability — and, for PreK–Grade 2, from the science standards in the 2024 Pennsylvania Learning Standards for Early Childhood. PECT still scores 0013.1 in 2014 Pearson language (inquiry, process skills, evidence). You must be bilingual: exam stems may say inquiry and process skills; classroom standards now say three-dimensional science.

Two languages, one classroom: PECT 2014 and STEELS

The Pennsylvania State Board of Education adopted STEELS in January 2022. Chapter 4 amendments were published as final in the Pennsylvania Bulletin on July 16, 2022. The 2002 Science and Technology and 2002 Environment and Ecology academic standards sunset June 30, 2025. STEELS is fully integrated into classroom instruction in school year 2025–26. OCDEL revised the Early Learning Standards science expectations to align to STEELS; 2024 updates cover Infant/Toddler, Prekindergarten, Kindergarten, Grade 1, Grade 2, and the Continuum.

STEELS is three-dimensional: children use Science and Engineering Practices (SEPs) and Disciplinary Core Ideas (DCIs) together with Crosscutting Concepts (CCCs) — often with Technology and Engineering Practices as well. They do not memorize a fact list, then maybe do a lab. Practices are what children do (ask, investigate, explain with evidence). Core ideas are what they are figuring out (needs of living things, pushes and pulls, weather). Crosscutting concepts are how they think across topics (patterns, systems, cause and effect). Pearson 0013.1's inquiry and process skills are the practices half. Unifying concepts wait for 0013.4. Do not invent unpublished STEELS codes on the exam; name the practice and the child evidence.

Exam move: If a stem says inquiry, pick the option where children investigate a question with materials. If a stem says STEELS or practices, pick the option where children do science, not only hear vocabulary. Both are correct languages for the same foundation.

Inquiry and process skills — named, not vibes

Scientific inquiry is a cycle of questioning, investigating, and explaining with evidence. It is not a kit, a Friday fun day, or a coloring sheet of a scientist in a lab coat. Process skills are the moves inside that cycle. Elementary science still names basic skills teachers can observe.

A child who only recites hypothesis, materials, procedure, conclusion has not yet used process skills. A child who melts ice, draws both cups, and says the sunny one melted faster has. STEELS SEPs (asking questions, planning investigations, analyzing data, constructing explanations, arguing from evidence, communicating information) are the same family in modern language.

Reliance on verifiable evidence

Verifiable evidence is something another person could check: an observation, a count, a measurement, a photo, a notebook record, a second trial. Science is not "the loudest guess" or "what the teacher already knew."

Wonder versus wild guessing is the exam distinction.

• Wonder starts with notice: The puddle is smaller after lunch. Then a testable question: Did the water go into the air? Then a plan for evidence: two cups, one covered, one open; measure; look again tomorrow.
• Wild guessing is a claim with no check: The floor ate it. If the adult says "good idea" and moves on, the child learned that science is opinion. If the adult says "how could we check?" the guess can become inquiry.

Do not shame a wrong idea. Do not treat every idea as equally true. The professional move is: claim → evidence → maybe revise. That is how scientific thinking interacts with cognitive development: children move from magical explanations toward cause they can test, still with concrete materials.

Hands-on before a vocabulary dump

Young children build science ideas from experience, then language. A PreK class that first plays with ice, water, and steam from a kettle the teacher controls can later learn solid, liquid, gas. A class that copies those words on Monday and "does the lab" on Friday has inverted the foundation.

Experience → talk → name → record is the sequence. Vocabulary is necessary; it is not the first move. Academic words (observe, evidence, melt, reflect, living) stick when they label something children just did. English learners and children with language IEPs especially need the material first, then the word with a gesture and a drawing — not a glossary packet in the hall.

Safety is part of science

Safety is not a lecture after the fun. It is a process skill and a practice: scientists protect people, living things, and tools.

PDE's STEELS Hub includes a Safety Guide. Follow district procedures and the school chemical-hygiene or elementary-science safety plan. Do not invent a numbered OSHA quiz for four-year-olds. Do teach stop, ask, don't taste, wear what we said, stay in the boundary.

How scientific learning interacts with development

Pearson asks for the two-way relationship. Science rides cognitive, linguistic, motor, social, and sensory development. It also grows those systems.

Piagetian caution (grain, not a delay excuse): PreK–K thought is largely preoperational — tied to what children see and do. Typical concrete-operational thinking in the elementary years supports conservation, classification, and more stable variable ideas, still with materials. Vygotsky is the teaching half: children construct science with others and with tools (language, notebooks, lenses) in a zone of proximal development. Waiting until a child "is ready for science" skips the work that builds readiness. Exclusion of children with disabilities or English learners is not developmental appropriateness.

PreK–K grain: senses, play with water/sand/magnets/plants, notice and wonder, sort, simple cause (push, melt, grow). Grade 1–2: more systematic observation, comparison, drawings with labels, first notebook habits. Grade 3–4: measurement, repeated trials, fair tests (depth in 0013.4), written explanations with evidence. Statewide PSSA science is a later accountability layer (confirm the current PDE tested grade — see 0013.3); it is not a reason to skip inquiry in PreK–2.

Scenario: PreK ice (hands-on before words)

Ms. Hale wants solid and liquid. She could hang a vocabulary chart and quiz four-year-olds. Instead she puts ice in tubs, lets children feel, watch, and pour the melt, then names solid and liquid for what they already did. Safety: no tasting the melt if the ice was handled; wash hands. That is 0013.1. The chart-first lesson was a dump.

Scenario: kindergarten wonder versus wild guess

A child says the class plant died because "it was sad." Mr. Ortiz does not mock and does not agree. He asks how could we check what plants need? Children put one plant in the closet and one in the window (same water, same pot). They draw both. The wonder became evidence. The untested feeling was a starting idea, not the conclusion.

Scenario: Grade 2 process skills, not a chant

The team recites scientific method steps each Monday. Children still cannot say what they observed. Ms. Patel instead has them observe mealworms, classify living/nonliving after criteria, communicate in notebooks, and infer from evidence. The chant was not inquiry.

Scenario: Grade 4 identity (two-way)

A child says, "I'm bad at science," after a parent called it a boy subject. Development here is identity. The teacher treats a wrong prediction as information, offers a second trial, and never ranks speed of "getting it." Science experiences shape whether the child will keep investigating.

Boundaries with nearby descriptors

You may melt ice in a scenario here. On 0013.1, pick the option that names how children learn science, not the option that dumps the water-cycle content list.

Exam traps for 0013.1

• Vocabulary first, investigation never — or a video in place of materials.
• Equating wild guessing with inquiry, or shaming a wrong idea instead of testing it.
• Treating safety as optional extra, or using safety to exclude children from science.
• Claiming STEELS repealed inquiry — or claiming PECT bans STEELS language. Teach both.
• Inventing unpublished standard codes or official age cutoffs. Describe child evidence.
• Waiting for Grade 3 or PSSA year to begin science.
• Dumping 0013.5–0013.8 fact lists into a foundations item.

When you plan, finish this sentence: "Children will use [materials / senses / a process skill] to gather [evidence] about [a question they can check], which also builds [language / motor control / identity]." If the leftover product could have been a word list with no investigation, it was not yet 0013.1 instruction.
