Chemical Compounds
Unit Overview
For students to learn the properties of chemical compounds. They will determine the importance of certain chemical compounds that are used in everyday life. The students will to identify characteristics of certain chemical compounds and have an understanding of how they are used throughout the world.
Personal Achievement
By the end of the unit, I was able to fully understand what chemical formulas represent.
Enduring Understanding:
A chemical formula is a formula that shows the atoms present in a specific molecule, and their relative proportions. Example: H2O. This shows that, in the molecule, for every two atoms of Hydrogen (H), there will be one atom of Oxygen (O).
Reflection on Progress Towards the Standards
Area(s) of Strength
Throughout the unit, I was able to identify elements in a chemical formula and their ratios compared to the other elements in the formula.
Area(s) for Improvement
The only thing missing for me to fully understand this unit, was to get the names of the molecules right. I know the elements, but I struggle figuring out the names of compounds based on the elements it contains and the proportions of these in the molecule.

One of our first Labs during this unit, was to look around the school for 20 different chemical compounds that we use/see everyday. We had to take pictures of them, write down their names, and write down their chemical formulas. This showed us that chemical compounds are everywhere.
