Test Review

Wednesday - Enzymes

Tuesday - Solving the Mystery

Monday - Macromolecule Murder Mystery

Friday - Proteins and Nucleic Acids

Wednesday and Thursday - Polymers, Lipids and Carbohydrates

Wednesday we learned that monomers (one unit)  join together to make dimers (2 units) and polymers (many units). It takes energy and gives off one molecule of water for each bond formed. This is called polymerization or dehydration synthesis.

Tuesday - Food Labels

Today we looked at proteins, carbs and fats (lipids) on food labels.

Monday - pH

Today we learned about acids, bases and pH. If you missed class, please use these pages to catch up/.

Friday - More properties of water

On Friday we talked about 3 more properties of water. High Specific Heat, Low Density of Solid Water (Ice), and Water as a Universal Solvent. We also took a quiz. If you missed this day, please make arrangements to make up the quiz when you get back to school.

Thursday - Properties of Water Part 1

Today we talked about water. Water is polar like a magnet. It is attracted to other water molecules (cohesion) and other objects like a straw (adhesion). Cohesion causes surface tension so bugs can walk on water. Adhesion allows water to move up from the roots to the leaves in plants.

Wednesday - Carbon

Today we learned about the properties of carbon (forms 4 bonds, makes long, complex molecules) and the organization of life from small and simple to large and complex. These are the pages that we completed. If you missed class, make sure you fill in these pages in your packet when you get back to class.
