[Intro – teasing, mysterious]

Ah… the atom changes form and face…
Each age reveals another place…
What once was whole is now divided…
By minds that dared — and never hid it.

[Verse 1 – Democritus Dalton]

Democritus said in 460 BCE “the world made of , (mezzo-forte)
Indivisible particles”
Dalton (1808) then boldly claimed: (mezzo-forte)
“They’re whole numbers spheres that mix and play —  (spoken and sung)

Each element’s atom stands alone.” (forte)

*(Chorus echo, piano soft: “all atoms of an element are different from other atoms of elements with other properties…different from atoms of other elements…”)

Same mass…per element…

[Verse 2 – Thomson Rutherford]

Thomson (1897) broke that stone — (forte)
Found electrons dancing on their own! (fortissimo)
A pudding sweet with charges spread… (mezzo-forte)
Then Rutherford (1911) boldly said: (forte)
“Electrons in empty space! A nucleus instead!”

(fortissimo)

*(Chorus echo: “Nucleus instead… nucleus instead…”)

[Verse 3 – Bohr  Quantum]

Bohr (1913) made paths of light, (forte)
Electrons circling day and night. (fortissimo)
But quantum minds soon changed the scene — (mezzo-forte)
In 1926 and 1927: (crescendo to forte)
Not just an orbit but with quantized energy levels, wave-particle duality, and probability— just clouds unseen!” (fortissimo)

*(Chorus echo, piano soft: “Clouds unseen… clouds unseen…”)

[Finale – soft – dramatic]

From solid ball to ghostly cloud, (mezzo-forte)
Each vision bold, each thinker proud. (crescendo)
Ah, the atom — never the same, (forte)
Forever changing — science’s flame! (fortissimo, hold last note)

building the atom

.     Build ONE of the following atomic models: Plum pudding (Thomson), Rutherford’s, Planetary (Bohr), or the electron cloud model (Quantum Mechanical model - Schrodinger). Include the following for full credit:

• A 2-D or 3-D model, labeled & with a key included to identify the subatomic particles.

The 2D model cannot be done on a sheet of paper. The base must be of sturdy material, and the size of the subatomic particles must be representative.

B. perform a poem (the spoken word), rap, or song, emphasizing

how the atomic model has changed over time with each new scientific discovery. This can

be presented live or as a recorded video in class. The poem should include the discovery

around all atomic models - Democritus, Dalton, Thomson, Rutherford, Bohr, and the

Quantum Mechanical/Electron cloud model. Include a bibliography page citing sources

used.

2. Choose one of the following options for an oral class presentation and upload to canvas by

the due date.

A. Research & present the development of the atomic theory (Democritus, Dalton, Thomson,

Rutherford, Bohr, and the quantum mechanical/electron cloud model) in a slideshow.

Include the following: dates, discovery, a picture or drawing of the atomic model and the

experiment used where applicable. Include a bibliography page citing sources used.

B. Research, compose, & perform a poem (the spoken word), rap, or song, emphasizing

how the atomic model has changed over time with each new scientific discovery. This can

be presented live or as a recorded video in class. The poem should include the discovery

around all atomic models - Democritus, Dalton, Thomson, Rutherford, Bohr, and the

Quantum Mechanical/Electron cloud model. Include a bibliography page citing sources

used.

C. Research & develop a timeline to show significant dates, the experiment done, the model

proposed, any discoveries related to the development of the atomic theory from

Democritus, Dalton, Thomson, Rutherford, Bohr, to the current quantum

mechanical/electron cloud model.

The timeline must be drawn on a poster board and must include color. Be creative!

Include a bibliography page citing sources used.
