Eisco Atom Model Activity Set

This hands on atom model allows students to build and explore the structure of atoms. 

Each set contains:

• • 1 clear plastic dome model base;
  • 25 yellow electron pegs;
  • 30 green proton balls;
  • 70 blue neutron balls.

The plastic dome can easily be removed by turning the model over and gently pushing on the three posts that hold the dome in place. When building your atom it is recommended to fill the nucleus first with the appropriate number of protons and neutrons. Keep the dome representing the nucleus upside down and then add the plastic disc that holds the electrons over top of the dome. Push the three pegs gently into place forming a tight seal, and then flip the clear plastic base over so that the dome is facing up before adding the electron pegs to the apparatus.

Accompanied by a 40-page experiment guide which includes teacher notes and student instructions for the following activities:

• • Activity 1: Modeling the Atom
  • Activity 2: Isotopes
  • Activity 3: Atomic Mass
  • Activity 4: Ions
