Fizzling — Physical Changes & Crystal Growth Crystal Growth Conservatory

Hi!

I'm Fizzling.

Welcome to Crystal Growth Conservatory!

Will you help me investigate physical changes & crystal growth?

The Grumblies have mixed up our clues.

Let's check the evidence!

Dissolving and changes of state can be physical changes.

Crystals may grow from a solution as dissolved material forms

an ordered solid.

Which material is recovered in our record?

  • A. Salt
  • B. A guaranteed new metal
  • C. A new kind of plastic

The answer is A: Salt

Dissolving and changes of state can be physical changes.

Crystals may grow from a solution as dissolved material forms

an ordered solid.

That clue helps us make sense of this place.

Crystal growth does not automatically prove a new substance formed.

Compare the material's identity before and after.

Does crystal growth always mean chemical reaction?

  • A. Yes
  • B. Only if crystals are large
  • C. No

The answer is C: No

Crystal growth does not automatically prove a new substance formed.

Compare the material's identity before and after.

Hmm...

how does that connect to our first clue?

Our record dissolves salt in water, then removes water

and recovers salt crystals.

The salt remains salt;

its form and distribution changed.

Which sequence fits?

  • A. Salt turns into sunlight
  • B. Dissolve salt, remove water, recover crystals
  • C. Destroy salt, create unrelated matter

The answer is B: Dissolve salt, remove water, recover crystals

Our record dissolves salt in water, then removes water

and recovers salt crystals.

The salt remains salt;

its form and distribution changed.

Nice investigating!
