STANDARDS OVERVIEW

Reading Strategy:

Learning to think, read, write, and speak like scientists.

Science Concept:

Scientists ask questions based on observations before they begin gathering information from texts and the natural world, and they benefit from working in teams to find answers.

NGSS:

3-LS3-1

CCSS:

SL.4.1

Science and Literacy Connection:

Scientists use different ways to observe the world, including reading scientific texts, conducting investigations, writing reports, and working collaboratively with others in the cycle of inquiry.

Science Language:

  • A trait is an observable characteristic that an organism is born with such as eye color, feathers, or the shape of leaves. 
  • Organisms are living things that carry out the activities needed to live, grow, and survive. 
  • Observation is carefully looking at something or someone to gather information.  
  • A scientist is a person who is an expert in or who studies aspects of the natural or physical world. 
  • A botanist is an expert in the scientific study of plants. 
  • A team, or teamwork, is a group of people who work together to accomplish a goal.  
  • Collaboration occurs when two or more people work together, learn from each other, and communicate with each other. 

  • Mini-Lesson

    OVERVIEW

    Teacher instructions are provided for each day’s mini-lesson. These instructions consist of declarative knowledge (statement of what children will do or learn), conditional knowledge (context or background related to what children will learn), and practical knowledge (explicit instruction and practice).  Today’s mini-lesson will simply explain what the children will be doing throughout the unit. The teacher will need to print out and post the “Inquiry Toolbox” and “Team Roles” anchor charts to use in the discussion. Alternatively, these could be created on chart paper.   Note: The teacher will need to assign children to teams before the next class. Review the options for creating teams in under Science Inquiry Circles in the separate document “Unit Overview for the Teacher”. 

    Materials for the Mini-Lesson:

    Teacher needs:  

    • “Inquiry Toolbox” anchor chart  
    • “Team Roles” anchor chart   

    PROCEDURE

    Each italicized statement below contains suggested wording the teacher may choose to use for the lesson; additional teacher actions and considerations are in parentheses.    

      

    Tell what the strategy is (declarative knowledge)  

    1. Today, you will learn about characteristics that plants inherit from their parent plants. Throughout this unit you will also learn about characteristics that organisms acquire during their lifetime due to interactions with their environment. Botanists, or plant scientists, can learn a lot by observing plants, but they can also learn from texts written by other scientists.  
    1. You will work together as a team in an inquiry circle to investigate the plants and environmental conditions in a particular ecosystem. This will help you understand more about how plants come to have the characteristics they have as a result of inheritance and interactions with the environment. In your inquiry circles, you will explore texts and media to find out more about the plants in your ecosystem. During inquiry circles, you can ask questions, discuss information you collect, and think about other questions you might have about plants in your ecosystem. The text-based inquiry involves asking questions and gathering information to answer these questions. In some ways, this is like the inquiry you engage in during a science investigation. We have an inquiry toolbox that will help you in your work. (Point to the “Inquiry Toolbox” anchor chart and read aloud to the class.)   

      

    Tell when and why to use the strategy (conditional knowledge)  

    1. When we investigate our plants in our ecosystem, we will practice our roles as scientists. We will do this because scientists use different ways to observe the world, including reading scientific texts, writing reports, and conducting investigations. You will take on the role of a scientist conducting inquiry by speaking like a scientist (using new science language), reading like a scientist (using strategies to find information), and writing like a scientist (using journals to organize important information and observations). There is no better way to learn about science than to become a scientist!  

      

    Tell how to use the strategy (procedural knowledge)   

    1. While in your inquiry circles, you will take on different science roles with duties within your team. Typically, science teams have a leader, called the Lead Scientist, and various other positions, such as Lab Director, Data Scientist, and Equipment Director. Each of these roles is important to the overall success of the team. (Point out and read each of the roles on the “Team Roles” anchor chart. At this point teacher can assign roles or allow children to choose their roles, letting them know that they will have the opportunity to assume different roles later.)  

    Post the “Team Roles” and “Inquiry Toolbox” anchor charts in your classroom so that the children can refer to them while in their inquiry circles. Encourage scientists to use them while in their inquiry circles.  

  • Inquiry Circles

    OVERVIEW

    During the first day of inquiry circles, teams will select one of three Texas Ecoregions: the Piney Woods, the Trans-Pecos and Blackland Prairie. Teams will first explore informational texts about the ecosystems present in each of these Texas Ecoregions (temperate forest, desert, temperate grassland). These informational texts are meant to grab the attention of learners and get them interested in the topic. Refer to the “Ecosystem Resources” spreadsheet in the “Before the Unit Begins” section, which includes suggested exploratory texts and media for selecting inquiry topics. Today, you may use the suggested print text for each ecosystem. If the print texts are not available, you may choose to use the suggested EPIC eBook for each ecosystem. If only some of these are available, you may also choose from other texts in the spreadsheet, but we suggest you choose only one print text or eBook for each ecosystem. Make sure to have exploratory texts ready ahead of time.   

      

    If you feel your learners may have difficulty reading the exploratory texts independently, you may choose to read the texts aloud to your learners prior to starting this unit. This option still allows the opportunity for learners to become interested when deciding which ecosystem to investigate.    

    Materials for the Inquiry Circles:

    Each team needs:  

    • access to a small selection of exploratory texts (one for each ecosystem option) 

     

    Teacher needs:  

    • “Ecosystem Resources” spreadsheet for ideas  

    PROCEDURE

    Each italicized statement below contains suggested wording the teacher may choose to use for the lesson; additional teacher actions and considerations are in parentheses.    

      

    Before Inquiry Circles    

    1. In your inquiry circles, you will become experts on the ecosystem your team has chosen and the plants that live there. Since it is not always possible to observe an ecosystem or a plant firsthand, scientists must turn to text and media resources to expand their knowledge. As scientists, you will also explore texts and media (e.g., books and Web pages) to answer your questions about plants and environmental conditions in your chosen ecosystem and build your expertise.  
    1. Today during inquiry circles, you will explore three kinds of ecosystems found in North America (temperate forest, desert, and temperate grassland). These ecosystems can be found in Texas too! Temperate forests can be found in the Piney Woods region; Deserts are found in the Trans-Pecos region; and temperate grasslands, also called prairies, can be found in the Blackland Prairie region. You can choose any of these three ecosystems and associated regions in Texas: Piney Woods (temperate forest), Trans-Pecos (desert), or Blackland Prairie (temperate grassland). No matter which ecosystem you choose, you will investigate the physical characteristics of plants in that ecosystem, environmental characteristics of the ecosystem, and other aspects of the ecosystem that you would like to know about. Before you decide which ecosystem to investigate, you will have the opportunity to read some exploratory texts to see what may interest you the most. (Be sure to have the books available for children. You may have the Equipment Director choose a book for the team or you may distribute the books. You may also want to project the Texas Highways Map of Ecoregions which can be found in the “Ecosystem Resources” spreadsheet.)   

      

    During Inquiry Circles (20 minutes)    

    1. Now that each team has a text to explore, you need to decide how to read it together. You may want to take turns by paragraph or page, but decide before you start. (You may decide if you want your learners to read the text closely or to browse the text and read only certain sections. Encourage learners to look at the texts to spark conversations about what they discover. What do they see in the pictures? What questions do they have?)  
    1. While you are reading, I will be walking around to assist you as needed. (Allow the class time to read while you facilitate when necessary. Rotate the texts so that each team had a chance to explore a book about each of the ecosystems. If you are using the EPIC eBooks, you may want to set a timer and let learners know when it is time to switch to the next book.)   
    1. When all inquiry circle teams are finished reading the exploratory texts, you will work together to briefly summarize what you read and make a decision about which ecosystem you want to learn more about. Rank the ecosystems from favorite (1) to least favorite (4). (Children can rank the ecosystems individually OR in teams, depending on which option for creating teams the teacher has chosen.)    
    1. Now that you have identified your top choices, think about your top two ecosystems that you would like to learn more about. What questions do you have about the plants in these ecosystems? Write down your questions on sticky notes. (Teacher will want to collect sticky notes and store them in a way that will allow learners to return to them tomorrow.) 

      

    After Inquiry Circles (10 minutes   

    1. The Data Scientist from each inquiry circle will now share the team’s top ecosystem choices, as well as anything interesting the team discovered today. What grabbed the team’s attention? (Be sure all members of the team assist the Data Scientist so that they are prepared to speak. Allow time for all inquiry circle teams to share.)   
    1. I will assign all ecosystems for investigation tomorrow. (If not already pre-assigned, teacher will need create teams and assign each team its ecosystem by the next lesson.)   
  • Guided Science Investigation

    OVERVIEW

    Learners will consider observable traits in plants.

     

    GUIDING QUESTIONS

    What are traits? How are parents and their offspring similar? How are they different?

     

    BACKGROUND INFORMATION FOR THE TEACHER

    A trait is a physical attribute of an organism, such as eye color, feathers, or the shape of leaves. Animals and plants of the same kind share basic traits that help us identify a species. However, not all individuals of the same species are exactly the same, some traits vary within a species.

    Traits can be inherited or acquired. Traits that are inherited are passed down from parent to offspring. Acquired traits are not passed down but are the result of environmental or external factors.

    NOTE: Starting tomorrow (unless the teacher has already assigned teams), children will be working in the same teams for the rest of the unit. The teams children work in during inquiry circles will be the same teams they work in during the guided science investigation. However, the team roles, or jobs, may change.

    Materials for the Guided Science Investigation:

    Each team member needs: 

    • science notebook 
    • pencil 
    • copy of (or digital access to) the “Organizing My Thinking: Traits” sheet  

     

    Teacher needs: 

    • “What Are Traits?” PPT 
    • copy of the “Organizing My Thinking: Traits” sheet (if not projecting digitally)  

    PROCEDURE

    Engage

    1. Ask learners, Do all plants look the same? Turn and talk to a partner and share your ideas. After a few seconds, turn to a different partner and again share your thoughts.
    2. Announce that you’re going to take the class outside to make some careful observations of any plants they may see. Caution the learners not to touch or handle any vegetation to prevent injury or irritation to the skin. (If you’re using indoor potted plants, they should be located where they can be observed from different angles. You may want to set up several different viewing areas and allow the learners to rotate between them. The same safety rule applies.)
    3. Instruct learners to carry their science notebooks with them to record their observations. They should look for physical features that are the same and features that are different. Remind them to consider plant structures they are familiar with, such as leaves, stems, and other plant parts.

     

    Explore

    1. Allow 15 minutes for exploration as you move between the teams to listen to their ideas.

     

    Explain

    1. After the exploration, randomly select team members to share their observations of the plants as a whole, whether outside or inside. Create a T-chart on the whiteboard to record similarities and differences. For example, a similarity might be that all plants had leaves; a difference might be that the leaves are many different sizes or colors. Record all student responses.
    2. Explain that the plant features they have described are called traits. Project slide 1 of the “Plant Images” PowerPoint. Explain that traits are physical attributes that can be seen, such as the shape or color of leaves. We can identify different species of plants by the traits they share.
    3. Ask, What traits in these plants do you see that are the same? (Possible answers should include leaves, stems, roots.) What traits make these plants different from each other? (Possible answers may include shape of the leaves, size, colors)
    4. Species in the same plant family may have similar features, but individuals can be different due to inherited and/or acquired traits. Project slide 2 of the “Plant Images” PowerPoint. Ask, What traits in these plants are the same? How are they different? Accept responses. (Possible answers may describe similar arrangement of leaves or coloring; differences may include shape of leaves.)
    5. Explain that traits that are inherited are passed down from parent to offspring. Acquired traits are not passed down but are the result of environmental or external factors.

     

    Elaborate

    1. Share that in the next class, teams will explore more about traits. Add that their work investigating plants in different ecosystems during inquiry circles is related to the work they will do in their science investigations. Both are important in helping them understand more about traits.
    2. Let learners know that, starting tomorrow, they will be working in teams for the rest of the unit. The teams they work in during inquiry circles will be the same teams they work in during science investigations. However, their roles, or jobs, may change.

     

    Evaluate

    1. Did children communicate a reasonable understanding of similarities and differences in plants based on their observations?
    2. Did children communicate a reasonable understanding of what a trait is?
