Matter structure and behaviour are covered in the IAB 2010 Pilot through the description and explanation of the state and change of state of the following systems:

Single particle systems:

• Atomic structure (structure of "elementary particles")
• Periodic table (Organization of single particle systems)

Many-particle systems (Molecular model):

• Chemical Bonding (construction of molecular models)
• Chemical reaction & chemical equations
• Electrochemistry: Electrical behaviour of particles

Many-particle systems as electron pair and proton exchangers:

• Acids & bases

Many-particle systems under thermodynamic & kinetic control:

• Chemical reactions & equilibrium

 

 

1- Analysis:

1. Predict whether A or B would have a greater effect on a given system (inferential).
2. Describe the electronic structure of a given system (descriptive).
3. Why must this experience be carried under a hood (causal).
4. Explain how each product is formed when A reacts with B (explanatory).
5. Distinguish between the 2 given systems (discriminatory).

2- Criterial thinking:

1. What criteria should be used to compare the properties of 2 given systems (comparison).
2. List the characteristics of each element in a given system (classification).
3. Calculate the value of the mass (or the volume) of a given system (measurement).
4. Arrange many given systems in increasing X (X= polarity, acidity or basicity...) (classification/comparison).
5. What are the factors affecting the rate of a given reaction (classification).

3- Relational thinking:

1. How can this type of reactions be used in electronic systems (extrapolation).
2. How can acid-base reactions be useful in biology (extrapolation).
3. How can the study of such properties be useful in other disciplines like biology (extrapolation).
4. What conclusion can be deduced from the following articles (synthesis).
5. How this type of transformations can be applied in chemical industries (extrapolation).

4- Logical thinking:

1. How do you justify the formation of this type of bond (justification).
2. Justify the electron configuration of a given system (justification).
3. Using the data listed in the Table below, convince yourself that the reaction proceeds in the direction shown (evidence-based argument).
4. According to a given reaction, justify the reactivity of the reactants (justification).
5. How can the chemical & physical properties of organic compounds be useful in developing sciences (petrochemistry, agrochemistry, pharmacology, food nutrition...) (esthetics/extrapolation).

5- Communication :

1. Represent a given chemical reaction by an equation (representation).
2. Represent a given molecule by a formula (representation).
3. What does the term "X" means (semantics).
4. What form does a molecule of "X" have (semantics)
5. Which graph describes the following experience (correspondence).
