Tootsie Pop Chemistry

Chemical Symbols,

Formulas,

and Equations


Supplies
Supplies

  • Tootsie-Pop (different color for each person in the group)

  • Colored pencils

  • Colored squares of paper to represent additional pop wrappers

  • Arrows and + signs

  • Science notebooks


Purpose
Purpose

Use chemical symbols to represent chemical formulas and equations.


If the flavors of Tootsie-Roll Pops represent different atoms or elements, how many different combinations can your group create?






Can you think of a better way
Can you think of a better way? Tootsie-Roll Pops?

  • Drawing pictures or writing out descriptions is quite tiresome and time-consuming.

  • Let’s give each color a symbol.

  • You can unwrap your lollipop now!!!


  • Grape – G Tootsie-Roll Pops?

  • Cherry – Ch

  • Chocolate – Cc

  • Orange – Or

  • Green – Gn

  • Raspberry -R



Use symbols to describe the following combinations
Use symbols to describe the following combinations: describe them using the color symbols.

  • orange and chocolate

  • chocolate, grape, and cherry

  • grape, cherry, orange, and green

  • OrCc

  • CcGCh

  • GChOrGn


  • Sets of symbols like GCh and OrCcG are called formulas. Each symbol represents one kind of atom.

  • If you have more than one of the same kind of atom in a formula you place that number after and a little below the line to show the number of atoms.

  • This number is called a subscript.

  • Example – Or2Cc



3 cherries and 5 chocolates ‘atoms’ in the following combinations.

Now write the formula -

Ch3Cc5


1 orange and 2 grapes
1 orange and 2 grapes ‘atoms’ in the following combinations.

OrG2

4 chocolates, 2 greens, 3 cherries

Cc4Gn2Ch3


Law of conservation of mass
Law of Conservation of Mass ‘atoms’ in the following combinations.

  • Matter can neither be created nor destroyed during a chemical change.

  • The total mass of all substances must be equal to the total mass after a chemical change.

  • There can be no loss of mass nor gain of mass during a chemical change.


Orch 2 ccg 2 orccg 4 ccch 2
OrCh ‘atoms’ in the following combinations. 2 + CcG2 OrCcG4 + CcCh2

  • Make the following combinations with your wrappers and papers.

  • Compare and record the number of ‘atoms’ on each side of the arrow.

_____ Or _____ Or

_____ Ch _____ Ch

_____ Cc _____ Cc

_____ G _____ G


Ccg orgn 2 org 2 ccgn
CcG + OrGn ‘atoms’ in the following combinations. 2 OrG2 + CcGn

Or + Ch2 Ch2Or

G + R2Ch  RChG + R2


What needs to be done to have these combinations of atoms obey the law of conservation of mass
What needs to be done to have these combinations of atoms obey the Law of Conservation of Mass?


Stay tuned
Stay tuned……. obey the Law of Conservation of Mass?

Tomorrow we will use coefficients to balance these equations!!
