Introduction

“Science at home”.” is an informal learning ecosystem that connects everyday phenomena with scientific methods, promoting scientific identity, causal reasoning, modeling, and evidence-based argumentation. The literature of the National Research Council/National Academies (e.g., Learning Science in Informal Environments y How People Learn II) and approaches such as inquiry (NGSS), constructionism (Papert) and maker education (Martinez & Stager) support its impact.

Why now: post-pandemic science literacy; accessible smartphone sensors and simulators (PhET); curricula focused on scientific practices.

Theoretical basis

  • Constructivism (Piaget): confronting previous ideas with evidence.
  • Sociocultural (Vygotsky): family mediation and co-exploration.
  • Constructionism (Papert): learning by building artifacts.
  • Scientific inquiry (NRC/NGSS): ask questions, investigate, analyze data and argue.
  • Situated cognition: authentic home contexts.
  • Motivation and identity (Deci & Ryan): autonomy, purpose and early achievement.

Historical evolution

From museums and clubs (20th century) to the maker movement (2005-), scientific citizenship (2010-) and domestic edtech (2015-), with emphasis on real practices and data.

Critical subtopics

A) Design of inquiry experiences

Definition Activities where questioning and evidence guide learning (not just “recipes”).

Evidence: NRC and NSTA show improvements in modeling, analysis and argumentation.

Discussions: confirmation vs. discovery; coverage vs. depth → hybrid and deep focus.

Common errors: confusing spectacle with research; not recording data and uncertainty.

Internships: logs, process rubrics, process cycle, process cycle P-I-D-C.

B) Safety and ethics in the home

Definition Identify risks and controls (PPE, ventilation, safe disposal).

Evidence: NSTA/ACS recommend controlled food substances and micro-risks.

Errors: reusing food containers, lack of labeling/supervision.

Internships: positive list (vinegar, baking soda, salt, yeast, magnets, paper...), SDS when applicable.

C) Evaluation and documentation

Assess scientific practices (planning, control of variables, error analysis) with family portfolio, graphs and mini-posters.

D) Technology and data

Use cell phone sensors (accelerometer, microphone, camera), simulators (PhET) and microcontrollers. Triangulate simulation + real measurement.

E) Inclusion and family approach

Low-tech versions, multimodal instructions and rotating roles to avoid stereotypes.

Practical applications

  • Home: “measurement Tuesday”, “failure Friday”.
  • School-family: in-house data → in-class analysis (acoustics, evaporation).
  • Business/edtech: open kits with challenges and data upload.
  • Scientific citizenship: biodiversity and air quality.
  • Health/sports: heart rate and biomechanics with slow motion.

Step-by-step implementation

6-12 week plan

  • Sem. 1-2: science station, safety, rubric and logbook.
  • Sem. 3-6: everyday physics, culinary chemistry, environmental biology.
  • Sem. 7-10: simulators + sensors; modeling with real data.
  • Sem. 11-12: family fair with posters and lessons learned.

Activity template

Example Levers: hypothesis “the higher the arm, the lower the force”; measure elongation of a rubber band vs. distance; discuss nonlinearity.

Common errors and myths

  • “I need expensive equipment” → prioritize pedagogical design + mobile sensors.
  • “Spectacle = learning” → demands data and explanation.
  • “Recipes guarantee” → without variable control is mechanical execution.
  • “Simulations substitute” → triangulate with real data.
  • “To fail is to waste time” → failure analyzed is learning.

Recommended resources

  • National Academies: How People Learn II; Learning Science in Informal Environments.
  • NSTA / AAAS / NGSS: practice guidelines, safety and scientific literacy.
  • Maker/Constructionism: Martinez & Stager, Invent to Learn; Tinkering Studio (Exploratorium).
  • Simulators and data: PhET; Zooniverse; SciStarter.
  • Low-cost: micro:bit/Arduino (optional), Foldscope, sensor apps.
  • NSTA Press: Everyday Science Mysteries; Argument-Driven Inquiry.

Case studies

  • Home acoustics: dB per room/hours → notion of logarithmic scale.
  • Bread fermentation: temperature and yeast → simple kinetics and control of variables.
  • Kinematics with video: free fall → quadratic adjustment, measurement error.
  • Phototropism: seeds with light slits → experimental design and plant hormones.

Strategic conclusion

The key is to move from flashy activity to evidence-based inquiryRecommendations: good questions, security, data, analysis and communication. Recommendations: stable routines, depth of coverage, triangulation (real+simulation+model), process evaluation and connection with real life or citizen science.

Annex: Glossary & FAQ

Glossary

Scientific inquiry: building knowledge with data and argumentation. Modeling: represent phenomena with diagrams/equations/simulations. Control variable: constant factor to isolate effects. Validity/reliability: quality of the method and consistency of measurement. Systematic/random error: constant bias vs. fluctuation.

ElementShort description
Title/QuestionDefine the phenomenon and the variable of interest.
HypothesisExpected relationship between variables.
DataMeasurements with units and error control.

FAQ

Did it not come out? Document, identify variables and redesign. Risks? Positive list, PPE, labeling, ventilation and monitoring. Without instruments? Uses cell phone sensors, stopwatch, kitchen scale, ruler. Motivation? Small goals, celebrate iterations, autonomy and show impact.
