PRESENTATION OUTLINE
PROJECT
- This project is about mixtures, elements, and compounds and what they mean
- And also what elements are found in the earths crust
MIXTURES
- A mixture is a combonation between two or more things to make a different substance
- They can be easily seperated
- Five examples are: salad, air (contains oxygen nitrogen and other gases),chex mix
- Soil, and mixed vegetables

- Homogeneous is when you cant see all the substances there is and cant take it a part
- Heterogeneous is when you can see the substances for that mixture and take them a part
- Homogeneous examples air and koolaid
- Heterogeneous examples lucky charms and oil and vinegar
ELEMENTS
- Elements are pure substances and are composed of the same atoms
- They can be broken down into one element
- Five examples are sodium, chlorine, hydrogen, oxygen, carbon, and nitrogen
COMPOUND
- Compounds are two or more elements chemically combined make compounds
- Can be broken down into individual elements
- Five examples are water, glucose, alcohol, salt, and ethanol
ELEMENTS IN THE EARTHS CRUST
- The most common elements in the earths crust are
- Oxygen 46.1%, silicon 28.2%, aluminum 8.23%, iron 5.63%
- Calcium 4.15%, sodium 2.36%, magnesium 2.33%, potassium 2.09%
- Titanium 0.565%, and hydrogen 0.14%
