Organisms and Their Environment Unit Plan Overview “Organisms and Their Environment” unit plan is designed to teach 4th grade students that organisms have needs and can only survive in environments that meet those needs. They will explore the diverse environments, the plants and animals that live in them, and how they adapt to survive in their environments through Web Quests. Standards Addressed 1. Organisms have basic needs and can survive only in environments in which their needs can be met. The world has many different environments, and distinct environments support the life of different types of organisms. a. Identify the characteristics of different environments, such as forests, wetlands, grasslands, deserts, and in polar, temperate, and tropical regions. a. Describe the diversity of life forms (vertebrate and invertebrate animals and plants) supported by each environment. b. Investigate the relationships between the basic needs of different organisms and whether or not a particular environment meets those needs. 2. Organisms have senses that help them detect internal and external cues. a. Analyze specific behaviors influenced by internal cues (e. g., hunger and thirst). b. Analyze specific behaviors influenced by external cues in the environment (e. g., temperature, light, and precipitation). 3. Many characteristics of an organism are inherited from the parents of the organism, but other characteristics result from an individual's interactions with the environment. a. Identify and describe characteristics and behaviors that are inherited (e.g., color of flowers and animal instincts). b. Identify and describe characteristics and learned behaviors that enable organisms to survive in their environment (e.g., bear learning to fish). Materials Web Quests Computers with Internet Access Access to PowerPoint Student Handouts Time of Unit Approximately 6 class days Lesson Plans (Day 1) Introduction-Begin unit with an interactive PowerPoint to introduce “Organisms and Their Environment” unit to students. Close lesson by giving students a short quiz found at the end of the PowerPoint presentation. (Day 2,3) Web Quest Days--Students are divided into groups (make tags): (Forest, Wetland, Grassland, Polar, Tropical, and Desert) Explain to students to be prepared to “teach” the class about the environment they are studying. They will meet with the other members in their group upon completion of their Web Quest to plan their “lesson.” (Take students to the computer lab). Give each student a handout to record their findings from the quest and let them begin exploring (Day 4) Sharing & Planning Day-- Student environment groups meet together to discuss their findings from the Web quest and to plan their “lesson.” Students use “Lesson Plan” handout to guide them in planning. (Day 5) Presentation Days—Student groups “teach” the class about their environments. (Day 6) Closure Lesson- Students pretend to be an animal from one of the environments for one day and writes about their experience. What do you see, hear, and eat? Describe the temperature/weather. What do you eat and how to you get your food? Students share stories with the class. Evaluations Web Quest evaluation Student writing evaluation
