MYP UnitMYP Unit Question: How can such a small thing impact our environment in such a big way? Area Of Interaction: Environment
Learner Profile: Inquirers
Essential Question: What makes an atom different from a molecule?
Standard: S8P1. Students will examine the scientific view of the nature of
matter. a. Distinguish between atoms and molecules. Learning Target: Today I am learning how tell the difference between atoms and molecules. This is important so that I understand the materials that make up my world .

Atoms:What do you recall about atoms?
Atoms are the building blocks of molecules, and molecules are the building blocks of matter.Molecules are extremely small. In one spoonful of sugar there are approximately 300 billion, billion molecules of sugar! Molecules can be made up of atoms of the same element, or molecules can be made up of a combination of atoms of different elements.
Work Session IAN pg. Title: Molecules
Today we will take Cornell Notes and create a flip chart on Molecules.
Turn to page in your IAN Notebook, title the page as Molecules.
What is an Element?An element is a pure substance that is made entirely from one type of atom that cannot be broken down into any simpler substance.
Elements are determined by the number of protons.
Define: Periodic TableThe periodic table is a tabular display of the elements, organized on the basis of their atomic numbers, electron configurations, and chemical properties.
Symbol
A one or two-letter set of characters used to identify an element.
Al is aluminum
C is carbonH is hydrogen
O is oxygen
Chemical Bond
A force that holds two atoms together
Molecule
Two or more atoms that are bonded together.
O2 – two like atoms bondedH2O – three atoms, not all alike
FormulaA combination of symbols that shows the ratio of elements in a compound.
Ex. H2O
Molecule foldable Book (IAN pg. )
Take a sheet of copy paper, after TITLE: write Molecules.
Take the scissors and cut each flap from the bottom to the title box (do not cut it all the way up to the top!!).
Label each tab as follows:TITLE:

Closing - Chalk TalkUsing the chalk provided answer
the following on your table.How can such a small thing make a big
impact on our environment?Compare the formula for water and hydrogen
peroxide.How does the addition of one more little
oxygen atom change everything?
