Download - Tootsie Pop Chemistry
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
If the flavors of Tootsie-Roll Pops
represent different atoms or elements, how many different combinations can
your group create?
•In your notebook, draw a picture of each combination.
•Which group can find the most combinations within 3 minutes?
• How many different kinds of atoms are represented by your Tootsie-Roll Pops?
• How many different combinations did your group make?
• Do you think any other group had the same combinations as your group did?
• Were there other combinations your group didn’t think of?
•Draw a picture description of this combination.
•Now write a description of this combination in words.
Can you think of a better way?
• 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!!!
Use symbols to describe the following combinations:
• 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
• Using the wrappers and colored paper squares, arrange the ‘atoms’ in the following combinations.
• If there is more than one ‘atom’, place the same ‘atoms’ on top of each other, but make sure you can count how many there are.
Law of Conservation of Mass
• 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.
OrCh2 + 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.
