5th Grade Science with Mrs. Salego Wednesday, September 26th Warm-up: Name one property of a base. Type your answer in a private chat message. Please set up audio wizard to make sure you are able to fully participate. Disclaimer: This session will be recorded for learning purposes. Learning purposes include: a lesson review for students who are absent, students who want to review for a test, etc.

Molecules of Life Reaction Rates OLS Lessons to be completed by Friday: Unit 1 Lessons 7-8 Molecules of Life Reaction Rates * You may have time to work on these assignments in class today.

Lesson 7: Molecules of life http://safeYouTube.net/w/u2se

Lesson 7: Molecules of life Big Idea #1 Proteins, Lipids, and Carbohydrates play a role in human nutrition. This Photo by Unknown Author is licensed under CC BY-SA-NC

Lesson 7: Molecules of life Proteins Composed of long chains of molecules called amino acids Form parts of your skin and muscles Help carry Oxygen throughout body

Lesson 7: Molecules of life Lipids Known as fats and oils Insulate body from cold Protect and cushion nerves Important source of energy Body stores extra energy as FAT

Lesson 7: Molecules of life Carbohydrates Main fuel that your cells “burn” to get energy Ex – bread, pasta, rice, potatoes Most basic carbohydrates are sugars – Glucose, Fructose, and Starch

Lesson 7: molecules of life Big Idea #2 – Organic Compounds VS Inorganic Compounds

Lesson 7: molecules of life Organic Compounds Most contain Carbon Found or produced in living things

Lesson 7: molecules of life Inorganic Compounds Usually DO NOT contain Carbon Produced by humans or in laboratories

Lesson 7: molecules of life Big Idea #3 – Living things are mostly composed of just a few elements: Carbon Hydrogen Oxygen Nitrogen This Photo by Unknown Author is licensed under CC BY-SA

Lesson 8: Reaction Rates

Lesson 8: Reaction Rates Big Idea #1 – There are 4 ways to increase the rate of a chemical reaction Increase the temperature Increase the surface area Increase the concentration Add a catalyst

Lesson 8: Reaction Rates Big Idea #2 All chemical reactions require a certain amount of ENERGY in order to break existing bonds in the reactants and form new bonds in the products This Photo by Unknown Author is licensed under CC BY-SA-NC

Lesson 8: Reaction Rates Big Idea #3 ENZYMES can act a CATALYSTS to speed up chemical reactions in the human body.
