Evidence Revealing the Composition of the Atom
Investigators use indirect evidence to guess what is occupying a sealed box. You could also use a set of plastic Easter eggs to encase the unknown items. Another terrific activity involves having high schoolers drop a pencil on a sheet...

Integrating Technology: Seeing Atoms: STM
In this atom worksheet, students learn about the scanning tunneling microscope and answer questions about its use, how it works and its ability to see electrons in atoms.
Curated OER
The Ghost Particle
Students collect evidence to make inferences about a object hidden inside a sealed box. They think critically and logically to raise questions. Students identify questions that can be answered through investigation. They formulate and...
Curated OER
Atomic Structure
Students investigate what is inside three different boxes using indirect observations and relate it to the discovery of the structure of the atom. In this atomic structure lesson plan, students explore the history of atomic structure by...
