Number of questions: 6 adapted activities, including identification of subatomic particles, analysis of electronegativity, classification of polar and nonpolar molecules, concept association, and interpretation of mixtures.”
Target audience:
Students with a good level of abstraction who have specific difficulties in Chemistry, especially in understanding atomic and molecular models.
Suitable for Middle School (8th and 9th grades) and High School.
Recommended for students with ASD (Level 1), ADHD, Dyslexia, difficulties with scientific reading, and students in the process of consolidating abstract thinking.
⚠️ This material is not recommended for students with Intellectual Disabilities, as it requires conceptual understanding of molecular structures, abstract relationships between electronegativity and polarity, and chemical generalizations that demand a higher level of formal reasoning.
Format:
Printable color PDF, with structural representations of molecules, color codes for electric charges, chemical symbols, objective instructions, and answer key included.
Objective
To deepen understanding of the concept of molecular polarity, addressing:
subatomic particles (atom, electron);
electronegativity;
identification of polar and nonpolar molecules;
the relationship between polarity and the mixing of substances (water, oil, alcohol, gasoline).
This material functions at an intermediate level and is recommended after a prior conceptual introduction to the topic.
Content
Recognition of the electron as the particle responsible for chemical interactions.
Understanding electronegativity as the attraction of electrons in a chemical bond.
Identification of nonpolar molecules through structural formulas (O₂, H₂, N₂, Cl₂, CH₄, CO₂).
Classification of mixtures based on polarity (water + alcohol, oil + gasoline).
Association between the concepts of polar, nonpolar, and the “molecule of life” (water).
Scientific justification for the immiscibility between water and oil.
Key features
✅ Accessible scientific language, without excessive mathematical formalism.
✅ Consistent use of colors, symbols, and visual structures to support reasoning.
✅ Activities that promote analysis, comparison, and conceptual generalization.
✅ Ideal for students who have already moved beyond the initial concrete phase of learning.
✅ Excellent for formative assessment or intermediate conceptual reinforcement.
✅ Saves approximately 2 hours and 45 minutes of teacher preparation time.
