Product Details

A new twist on crystal growing! In this activity, students cut out and assemble miniature paper trees. The trees are placed in a solution of Prussian blue, sodium chloride and ammonia. Overnight the trees become “snow-covered” in a thick, delicate envelope of salt crystals. This beautiful white forest is sure to be a classroom favorite. Includes detailed instructions and a reproducible student worksheet.

The Student Laboratory Kit is complete for 30 students, each making one tree. The Super Value Kit is complete for 5 classes of 30 students to each make one tree (150 trees).

Performance Expectations

HS-PS1-2: Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-PS1-3: Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.
