Particles are often misrepresented in sketches with no differentiation made between atoms and molecules. Electrons move in fixed orbital paths around the nucleus (strict adherence to the Bohr rather than Quantum Model).

This interactive lab shows how Rutherford was able to conclude that most of the space in an atom is empty Interactive A/CHEM12CA.html SC.912.P.8.3 Pearson chapter 4 interactive addressing how small an atom is and the relative size of it’s components. Also discusses that most of an atom is empty space. This would only take about 10 minutes for a student to finish and it might be good for the teacher to write some questions for them to answer as they went through it. This interactive could also be projected on the screen and gone through together as a class. Video - UT-04/player.html SC.912.P.8.4 Pearson 5 minute video chapter 4 on using chemistry to solve a crime. Detectives find a dead boy and look at the minerals in his bones to determine where he is from. (when people eat locally grown foods the minerals in the soil become incorporated into a consumer’s bones) Also goes over the parts of an atom.
