Essential question: How does three-dimensional shape influence molecular behavior?
Molecules with polar bonds can be overall polar or nonpolar.
Build an initial model and explanation for: How does three-dimensional shape influence molecular behavior?
Record observations, questions, an initial model, and one claim that could be tested. Use these concepts where relevant: electron domain; geometry; polarity; dipole; symmetry.
Study and explain the week's core ideas: electron domain; geometry; polarity; dipole; symmetry
Open text on VSEPR and molecular polarity.
Revise Monday's model. Add two evidence-backed annotations and explain one limitation or uncertainty.
Use geometry to predict net dipole qualitatively.
Show units, setup, calculation or graph reasoning, then write what the quantitative evidence can and cannot establish about: How does three-dimensional shape influence molecular behavior?
VSEPR model-building with safe kits or paper models.
Use the course safety charter. If supervision, facilities, materials, or conditions are not appropriate, use the supplied-data/simulation alternative rather than improvising hazardous procedures.
Record variables or design constraints, procedure/model, observations/data, and one revision you would make after reviewing the evidence.
Answer the essential question: How does three-dimensional shape influence molecular behavior?
Submit a claim, at least two specific pieces of evidence, reasoning that connects them, one limitation/counterclaim, and a correction note for any essential concept below 80%.
Select one artifact from this week and explain why it is trustworthy evidence of growth.
