Viewers will see and hear about the characteristics of all living things and how they contrast to characteristics of nonliving things. Learn how all living organisms are made up of cells. Science S3 Sixth Grade Module 6-2.1 1 Assessment Guidelines From the SC Science Support Document: The objective of this The objective of this indicator is to summarize characteristics that all organisms share; therefore, the primary focus of assessment should be to generalize the major points about characteristics that all organisms share. However, appropriate assessments should also require student to recall or exemplify the characteristics of organisms; or compare how organisms obtain food or reproduce.

August 2010 Science S3 Sixth Grade Module 6-2.1 2 Sixth Grade Science Module 6-2.1 Structures, Processes and Responses of Plants Lesson A Standard 6-2: Students will demonstrate an understanding of structures, processes, and responses of plants that allow them to survive and reproduce. Indicator 6-2.1: Summarize the characteristics that all organisms share (including the obtainment and use of resources for energy, the response to stimuli, the ability to reproduce, and process of physical growth and development). Other indicator addressed: 6-1.1 Differentiate between observation and inference during the analysis and interpretation of data. August 2010 Science S3 Sixth Grade Module 6-2.1 3 From the South Carolina Science Support Documents: Indicator 6.2.1: Summarize the characteristics that all organisms share (including the obtainment and use of resources for energy, the response to stimuli, the ability to reproduce, and process of physical growth and development). Taxonomy level: Understand Conceptual Knowledge 2.4-B Previous/Future knowledge: In kindergarten (K-2.2), students identified examples of organisms and nonliving things. Students have explored the basic needs (food, shelter, water, space, and shelter) of plants in 1st grade and of animals in 2nd grade. It is not essential for students to know the characteristics that separate living organisms from nonliving things. All living organisms share the following characteristics: They obtain and use resources for energy All organisms must obtain resources, such as food, oxygen, and water, which provide required energy to perform the basic processes of life, such as growing and developing, or repairing injured parts. Autotrophs (for example plants) provide their own food for energy through the process of photosynthesis, while heterotrophs (for example animals) must find an external source for food. Energy is released from food in most organisms through the process of respiration. They respond to stimuli A stimulus is any change in an organism’s surroundings that will cause the organism to react. Examples of environmental stimuli may be changes in the amount of light present, changes in temperature, sound, amount of water, space, amounts or types of food, or other organisms present. The reaction to the stimulus is called a response. It can be an action or behavior performed by the organism. They reproduce Organisms have the ability to reproduce, or produce offspring that have similar characteristics as the parents. There are two basic types of reproduction: o Asexual reproduction: a reproductive process that involves only one parent and produces offspring that is identical to the parent. o Sexual reproduction: a reproductive process that involves two parents. The egg (female reproductive cell) and sperm (male reproductive cell) from these two parents combine to make an offspring that is different from both parents. August 2010 Science S3 Sixth Grade Module 6-2.1 4 They grow and develop Growth is the process whereby the organism becomes larger. Development is the process that occurs in the life of the organism that results in the organism becoming more complex structurally. Organisms require energy to grow and develop. It is not essential for students to know about the origins of life, mitosis or meiosis, or the chemical equations for photosynthesis and respiration. Assessment Guidelines: The objective of this indicator is to summarize characteristics that all organisms share; therefore, the primary focus of assessment should be to generalize the major points about characteristics that all organisms share. However, appropriate assessments should also require student to recall or exemplify August 2010 Science S3 Sixth Grade Module 6-2.1 5 Teaching Indicator 6-2.1: Lesson A- Basic Needs of Organisms Instructional Considerations: This lesson is an example of how a teacher might address the intent of this indicator. Living things are identified by some basic characteristics. The lesson allows students to distinguish between living and nonliving things. Over time, students will begins to understand that all living things grow, breathe, reproduce, excrete, respond to stimuli, and have similar basic needs like nourishment. Page Keeley, author of Uncovering Student Ideas in Science. Vol 1. (NSTA Press. 2005) suggests a mnemonic to help students remember these characteristics. MRS GREN: M = movement, R=respiration, S=stimuli response, G=growth, R=reproduction, E=elimination of waste (excretion), N=nutrition (acquiring or making food) Preparation for the Lesson: Obtain and prepare picture cards of living and nonliving things Misconceptions: Students have difficulty characterizing things as living or nonliving. For example, they tend to describe anything that moves as alive. The cycle of life (birth, growth, death), and therefore they often classify living as nonliving because it has died. In science, living is used to describe anything that is or has ever been alive; nonliving is used to describe anything that is not now nor has ever been alive. Over time, students will begin to understand that all living things grow, breathe, reproduce, excrete, respond to stimuli, and have similar basic needs like nourishment. Safety: Safety must be emphasized at the beginning of the school year and reinforced with every lab activity. Students should understand that safety is everyone’s responsibility. Lesson time: 1 day (1 day equals 55 minutes) Materials Needed: SC Streamline Video Overhead and student copies of graphic organizer Picture cards of living and nonliving things (pages 7-15) Focus Question: What are the characteristics of living organisms? Engage: 1. Have students think about a time they have had to sort, arrange, or classify different types of things (Examples: laundry, groceries, dishes, etc)? Ask them what they were actually doing when they sorted or classified (arranged things into smaller groups). 2. Ask students to suggest ways they might classify different things in the classroom? Take their suggestions, and then tell them: Today we’re going to August 2010 Science S3 Sixth Grade Module 6-2.1 6 classify things in the classroom as living and nonliving. Allow students time to make two lists in their personal notebooks and list the items in the appropriate list. 3. Ask students to share the characteristics, special features or qualities they used when classifying the items in the classroom as living and nonliving. 4. Pair students and have them talk about those characteristics that the items that are living have in common. Have them develop a list of the characteristics that all living things possess. Explore: 1. Explain that the process of arranging or classifying into classes or a group by their similarities is called classification. 2. Provide the students with a set of picture cards including living and nonliving things. Allow time for groups of students to classify cards into the two distinct groups. Note to Teacher: You can print these out on cardstock and laminate them for future use. You do not have to have the identification words on the cards, they are there for you to identify the picture if a student asks. 3. Provide time for students to use the living things cards and discuss and list the characteristics and basic needs of organisms featured on the cards. 4. Compile a class list of the features of living things. (See list below) Once they have shared their features, discuss with them the definitions of response, stimulus, energy, growth and development and reproduction as they apply to living things. Response-all organisms react to changes in their environment; react to a stimulus with a response. Stimulus - a change in the environment that causes organisms to react. Reponses - an action or change in behavior. Energy- all cells in the body need energy to grow, repair, and carry out life functions. Growth and Development- the process of increasing in size and development is the process of change that happens as an organism become more complex. 5. Ask students to illustrate examples of the features of living things in their notebooks: Living things respond Living things use energy Living things grow and develop Living things reproduce 6. Show the SC Streamline Video: “The Basics of Biology: What is Life? “ (7:44) and ask students to add other significant information or questions they may have about the characteristics of living organisms. 7. Have students draw the graphic organizer (chart) below in their notebooks. Instruct them to select four living cards from the set of living organism cards and use them to complete the graphic organizer/data chart from below. Discuss each heading, provide examples and add them to the graphic organizer. If this is the first time students have worked with this organizer, August 2010 Science S3 Sixth Grade Module 6-2.1 7 you may want to model the process by completing it for one of the organisms. (Use the science support document to develop each concept listed below) Obtain Resources Response to stimuli Grow and Develop Reproduce 8. Allow time for students to complete the data chart below using the four living organism cards they selected. Characteristics of Organisms Organism Obtain Resources Response to Stimuli Energy use Reproduce Explain: 1. Divide students into groups and have them complete a claims and evidence chart on their assigned question. Example: We claim that one of the features of living things is growth because we know that all the living things on the cards we examined have a life cycle. 2. Have students post their charts. 3. Allow time for class discussion/discourse. 4. Ask each group to share their poster and be ready to answer any questions other classmates may have. 5. Questions to pose during class discussion might include: What are the features of living things? What do all living things need? What are two ways organisms obtain resources? Discuss different ways organisms respond to stimuli. What are two ways that organisms reproduce? Discuss and explain the difference between growth and development. Growth is the process whereby the organism increases in size. Development is the process that results in the organism changing and becoming more complex structurally. Assess student understanding by having them reflect by answering the focus question in their notebooks and then sharing their thoughts with cooperative group members. Extend: 1. Allow the students to reflect in cooperative groups using text information, data charts and any other resources they have available. Each group will share information on two living organisms with the class. 2.
