About This Lesson

Overview: Determine the relationship between density and buoyancy. Will it float or sink?

Learning Targets 

Students can: 

  • Use a digital simulation to collect science data. 
  • Use displacement to determine the volume of an object. 
  • Calculate density. 
  • Draw molecule diagrams to model the density of solids and liquids. 
  • Predict if a material will float or sink given the density of the material and the density of the fluid. 
  • Compare the density of the gas inside the balloon used in the movie The Aeronauts with the density of the gas in our atmosphere.

Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.
Develop models to illustrate the changes in the composition of the nucleus of the atom and the energy released during the processes of fission, fusion, and radioactive decay.
Communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.
