Bell Ringer: 10/3/17 Objective: Use appropriate terminology in the context of studying chemistry, including atom, element, molecule, and compound. Questions: Write the cellular respiration equation. What is cellulose and what is it’s function? (You may need to look this one up)
Where can I find chemicals in my body? A chemical is a substance that is made up of elements/molecules and used in chemical reactions.
Atoms are the basic building blocks of ALL matter in the universe! Atom: Smallest particle of an element that still has all of the properties of that element Atoms are the basic building blocks of ALL matter in the universe!
Element: Single substances that cannot be broken down into simpler substances What are some elements you know?
Compound/Molecule: The chemical combination of two or more elements. Can you think of any other compounds? What elements can you pull out of these compounds?
Chemical Formula vs. Structural Formula Chemical Formula: Each element is represented by its chemical symbol and the number of atoms is shown in its subscripts. Ex. H2O, CO2, CH4, C6H12O6 Structural Formula: shows the chemical symbol of each element and how they are bonded to one another.
Organic vs Inorganic Organic: Usually composed of carbon and hydrogen. “Organic Chemistry” means the study of carbon- containing compounds. Inorganic: They do not contain bonds between carbon atoms
Organic Inorganic C6H12O6 : Sugar C2H6 : Ethane C5H10O5 : Ribose C3H8O3 : Glycerol H2O : Water NaCO2- : Sodium Carbonate O2 : Oxygen Water is the most important inorganic compound. Most organisms are 60-90% water by weight.
Intro to biochemistry individual practice Need: Worksheet, Chromebook, Writing Utensil Connections Section: Use #1 Important Elements on my weebly to answer questions
Using the scientific method… Question What foods have polysaccharides? Research….Here is what I know Hypothesis If…then… Experiment Data & Data Analysis Discussion and Conclusion Publish
Identifying polysaccharides GOGGLES!!!!!! Place SMALL pieces in test tubes so they don’t get stuck. Don’t use over 10 drops of iodine ever. Positive result rust to black.
CLEAN UP INSTRUCTIONS Throw potato and cereal in the trash. Goggles go back to shelf. Clean out test tubes with brush cleaner. Wipe down tables.
What is a polysaccharide? Define polysaccharide. Provide some examples of polysaccharides. How do we create a polysaccharide? Where can we find polysaccharides? What are they used for? How do we test for polysaccharides?
