DESCRIPTION
Life Science Topics Unit - Download .ppt at www.sciencepowerpoint.comThis .Powerpoint is Part I/IV of an educational unit titled "The Life Topics Unit" that covers BIology / Chemistry / and Health Topics. The Powerpoint version of this video and entire unit can be downloaded at http://sciencepowerpoint.com/index.html Teaching Duration = 5 weeksThe Life Topics Unit is intended for students in grades 7-10 and includes an interactive and engaging Powerpoint Presentation of 1100+ slides with built in class notes (Red Slides), lab activities, project ideas, discussion questions, assessments, challenge questions with answers, review games, videos, and much more. Text is provided in large print (32 font) and is placed at the top of each slide so it can seen and read from all angles of a classroom. A shade technique and color coded text helps to increase student focus and allows teacher to control the pace of the lesson. Also included is a 12 page (Microsoft 2003 word doc.) assessment / bundled homework package that chronologically follows the Powerpoint slideshow as well as a 8 page modified assessment. 13 pages of class notes (Word doc.) with images are also included for students who require assistance, as well as answer keys to both of the assessments for support professionals, teachers, and homeschool parents. 22 video shorts (FLV files) are provided and a slide within the slideshow cues teacher / parent when the videos are most relevant to play. Video shorts usually range from 2-7 minutes and are included in organized folders. Two Powerpoint review games (125+ slides each) are included. Answers to the Powerpoint review games are provided in Powerpoint form so students can self-assess. Lastly, several class games such as guess the hidden picture beneath the boxes, and the find the hidden owl somewhere within the slideshow are provided. Difficulty rating of 9 (Ten is most difficult).Areas of Focus within The Life Topics Unit:-What is SPONCH?, SPONCH Elements / Biologically Important Molecules, % of SPONCH in Living Things, Organic Building Blocks, Carbohydrates, Simple to Complex Sugars, Proteins, Grrr (Growth, Repair, Reproduce, Regulate), Structural Proteins, Lipids, Types of Fats, Nucleic Acids, What is inside a Twinkie?, Dangers of Obesity, Why Fast Food Sells?, Dangers of Anorexia, Dangers of Bulimia nervosa, Dangers of Anabolic Steroid Use, Nucleic Acids. DNA, RNA, What does it mean to be living?, Characteristics of Living Things, Origins of Life (Other Theories), Origins of Life (Science Theory), Needs of Living Things, Origins of the Universe.(Timeline), Miller-Urey Experiment, Amino Acids, How Water Aided in the Origin of Life, Human Evolution, Hominid Features, Evidences of Human Evolution, Hominid Skulls.Please visit http://sciencepowerpoint.com/index.html to learn more about this unit, and the other 18 units in Life, Earth, and Physical Science for students in grades 5-10.

• Answer: Simple sugars such as a candy bar or sugar drink will give you quick short burst of energy, while complex sugars such as starch are longer lasting energy but require more time to break down.
• Starch is a major component of bread. We can find starch in breads and pasta, vegetables, and tubers like potatoes and yams.

• Candy bars have lots of simple sugars such as glucose and fructose.
• Simple sugars can be broken down quickly for short energy, Complex sugars have more energy, but it takes longer to break them down.
