Essential question: Why can a heavy ship float while a small dense object sinks?
Floating depends on density and displaced fluid, not mass alone.
Build an initial model and explanation for: Why can a heavy ship float while a small dense object sinks?
Record observations, questions, an initial model, and one claim that could be tested. Use these concepts where relevant: density; pressure; buoyancy; Archimedes principle.
Study and explain the week's core ideas: density; pressure; buoyancy; Archimedes principle
Open fluids text.
Revise Monday's model. Add two evidence-backed annotations and explain one limitation or uncertainty.
ρ=m/V; pressure; buoyancy comparisons.
Show units, setup, calculation or graph reasoning, then write what the quantitative evidence can and cannot establish about: Why can a heavy ship float while a small dense object sinks?
Water displacement with small safe objects or simulation.
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: Why can a heavy ship float while a small dense object sinks?
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.
