(1) p. 1-6, Atoms and Molecules
Molecules in Solids and Liquids (for younger kids, but still works!)
(Same as "Eureka!" Episodes 16 & 17 combined.)
Molecules are made of two or more atoms.
Eureka! Episode 22 - Atoms
Basically atoms and elements are the same thing.
An atom is just the smallest amount of an element.
Read this ice cream analogy.
Eureka! Episode 23 - Electrons
Making Molecules with Atoms
►The Periodic Table of Elements with the names of the elements.
Some of the names of elements are copper, iron, and aluminum, carbon, oxygen, and helium, or potassium, calcium, and zinc.
Do you have any gold jewelry? How can you know if it is pure gold or not?
Atoms and Molecules
Elements (atoms or molecules) and Compounds (a molecule)

►Study this awesome diagram. Hover your mouse over the parts of the image.
(2) p. 8-10a, Measurements and Units; The Metric System
(3) p. 10-12a, Manipulating Units
(4) p. 12-18a, Converting Between Units
►Unit Multipliers at Donna Young.
Simple, easy! A bit loud, so you may want to turn it down.
Look at Table 1.3 on p. 15 - Relationships between English and Metric Units.
And these symbols can mean approximately equal to: ≈, ≃, ≅.
More practice. =)
(5) p. 18-21, Concentration
It matters what air we breathe!
We normally breathe about 21% oxygen in the air we breathe. The rest that is not oxygen, but other harmless gases, we simply breathe back out along with Carbon Dioxide.
Sometimes a patient needs more, like higher concentration of 80% oxygen.
People with Chronic Obstructive Pulmonary Disorder (COPD) cannot have high concentrations of oxygen.
