LIFE SCIENCE
This week - 4/11-15/11:
Current Unit: Physical Science
7.2.1.1.1 Recognize that all substances are composed of one or more of approximately one hundred elements and that the periodic table organizes the elements into groups with similar properties.
7.2.1.1.2 Describe the differences between elements and compounds in terms of atoms and molecules.
7.2.1.1.3 Recognize that a chemical equation describes a reaction where pure substances change to produce one or more pure substances whose properties are different from the original substance(s). Essential Question 1: What are elements and compounds in the terms of atoms and molecules? Developing Understanding: Enduring Understanding: What understanding will I need to demonstrate? Essential Question 2: What is the periodic table and how does it help us organize the elements? Developing Understanding: Dynamic Periodic Table Website Enduring Understanding: Essential Question 3: What is a chemical reaction and how does it differ from a physical change? Developing Understanding: 1. Pennies 2. Reactions Enduring Understanding: Past Units: Genetics 7.4.3.1.1: Recognize that cells contain genes and that each gene carries a single unit of information that either alone, or with other genes, determines the inherited traits of an organism. 7.4.3.1.2: Recognize that in asexually reproducing organisms all the genes come from a single parent, and that in sexually reproducing organisms about half of the genes come from each parent. 7.4.3.1.3: Distinguish between characteristics of organisms that are inherited and those acquired through environmental influences. 7.4.3.2.1: Explain how the fossil record documents the appearance, diversification and extinction of many life forms. 7.4.3.2.2: Use internal and external anatomical structures to compare and infer relationships between living organisms as well as those in the fossil record. 7.4.3.2.3: Recognize that variation exists in every population and describe how a variation can help or hinder an organism’s ability to survive. 7.4.3.2.4: Recognize that extinction is a common event and it can occur when the environment changes and a population’s ability to adapt is insufficient to allow its survival. 7.4.4.1.1: Describe examples where selective breeding has resulted in new varieties of cultivated plants and particular traits in domesticated animals. EQ1: What are genes and how do they influence traits organisms inherit?
Developing Understanding: 1. Class Traits
Enduring Understanding: What understanding will I need to deomonstrate on a quiz? Essential Question 2: If all living organisms have the same "ingredients", why is there such diversity of life on earth? Developing Understanding: 2. Fossil Beaks Enduring Understanding: What understanding will I need to demonstrate? Essential Question 3: How can humans affect the traits that organisms show? Developing Understanding: Enduring Understanding: What understanding will I need to demonstrate? Essential Question 4: How can genetics and plant reproduction concepts be applied to find out the paternity (father) of a generation of Wisconsin Fast Plants? Developing Understanding: Enduring Understanding: What understanding will I need to demonstrate? Cells!
Minnesota Academic Standards for This Unit: 7.4.1.1.1: Recognize that all cells do not look alike and that specialized cells in multicellular organisms are organized into tissues and organs that perform specialized functions.
7.4.1.2.1: Recognize that cells carry out life functions, and that these functions are carried out in a similar way in all organisms, including animals, plants, fungi, bacteria and protists.
7.4.1.2.2: Recognize that cells repeatedly divide to make more cells for growth and repair.
7.4.1.2.3: Use the presence of the cell wall and chloroplasts to distinguish between plant and animal cells. Essential Question 1: Do cells have the same structures and life functions in different organisms? Developing Understanding: 1. Micro Slides 2. Cell Gizmo 3. Cell City Enduring Understanding: What understanding will I need to demonstrate on a quiz? Essential Question 2: How do different kinds of cells work together to do various jobs in an organism? Developing Understanding: Enduring Understanding: What understanding will I need to demonstrate on a quiz? Essential Question 3: What do cells have to do with growth and repair of injuries? Developing Understanding:
Enduring Understanding: What Understanding will I need to demonstrate on a quiz?
Microbiology and Disease Checklist Minnesota Academic Content Standards for This Unit: 7.4.4.2.1: Explain how viruses, bacteria, fungi and parasites may infect the human body and interfere with normal body functions. 7.4.4.2.2: Recognize that a microorganism can cause specific diseases and that there are a variety of medicines available that can be used to combat a given microorganism. 7.4.4.2.3: Recognize that vaccines induce the body to build immunity to a disease without actually causing the disease itself. 7.4.4.2.4: Recognize that the human immune system protects against microscopic organisms and foreign substances that enter from outside the body and against some cancer cells that arise from within. Essential Question 1: What are the structures and functions of germs and how do they reproduce? Bacteria and Virus Research: Cells Alive: Bacterial Cell Structure Cells Alive: "Oh My Goodness, My E. Coli Has a Virus!" Current Topic Article: "Getting the Goods on Good Bacteria" Essential Question 2: How do bacteria and viruses infect the body to cause disease and how can they be prevented, treated, or cured? The Flu Videos (Use these if you missed them in class!) Nova ScienceNow: 1918 Flu (Bird Flu) Bacterial and Viral Disease Research: Viral Infections: Medline Plus (See related topic box) Bacterial Infections: Medline Plus (See related topic box) Mayo Clinic - Diseases and Conditions Essential Question 3: How does my immune system help to protect me against diseases and how do vaccines help my body do that? Immune System and Vaccines: Video: "An Inside Look at the Flu" Video: "How Do Vaccines Prevent Illness?"
