STANDARDS OVERVIEW

Reading Strategy:

Learning how to synthesize information.

Science Concept:

The force of gravity on Earth pulls plant roots in a downward orientation. This response to gravity is called gravitropism.

Reading TEKS:

4.6H

Science TEKS:

2024–25: 4.1D

NGSS:

4-LS1-1

CCSS:

RI.4.9

Science and Literacy Connection:

Scientists synthesize what they have read by other scientists with what they already know and put that information together in a new way.

Science Language:

  • Observation is carefully looking at something or someone to gather information.   
  • Using models in science helps us to make pictures in our minds about things that might be otherwise difficult to understand. 
  • The radicle is the first part of the seedling to emerge from the seed. It will become the root system as the plant grows. 
  • Gravity is the force that pulls objects toward Earth. 
  • Microgravity is a very weak or reduced force of gravity. It causes the condition of weightlessness in space. 

  • Mini-Lesson

    OVERVIEW

    Scientists put together new information about the world every day. Before they conduct their own investigations, scientists read lots of texts written by other scientists about their work. Scientists “synthesize” what they read with what they already know and put that information together in a new way. “Synthesis” means making something new by putting things together.  

      

    Today, you will model how to write a synthesis statement using the shared inquiry question and apple trees as a model plant. Teams will then write a synthesis statement for each inquiry question on their Inquiry Chart by combining (synthesizing) the findings in each column.   

      

    Note: You are encouraged to create the “Synthesizing” anchor chart with your learners as you move through the lesson, using the provided anchor chart as a model. Post it for easy reference when completed and remind learners to refer to the anchor charts during inquiry circles.  


    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. It is time to get into our inquiry circles. You will be with the same team as yesterday, but we will rotate the science roles. (Assign roles at your discretion and have the Equipment Directors gather the Inquiry Chart for their team).  
    1. We have answered all (or most) of our Inquiry Chart questions. Today we will write our synthesis statements, so we need to be sure we have completed the Inquiry Chart. (Make adjustments for teams that have not yet completed their Inquiry Charts.)   
    1. Now, inquiry teams will work together on their synthesis statements.  

     

    During Inquiry Circles (20 minutes)    

    1. When all questions are answered on your Inquiry Chart, your team will work together to write a synthesis statement for each one of your inquiry questions.   
    1. When writing your synthesis statements, remember to synthesize all the information in the column under each question. You probably have information from multiple sources as well as some information from your own knowledge.  
    1. As you work to write your synthesis statements, remember the synthesis statement from our mini-lesson today. (Refer to the written statement.)  
    1. Choose one inquiry question at a time and write a synthesis statement as a team. (You might also give teams the option to divide up the inquiry questions and have each team member write one synthesis statement. Facilitate in a way that works best for your learners.)  
    1. Write your synthesis statements in your science notebooks.  
    1. Do not forget to use the anchor charts to help guide your thinking. (Refer to the posted anchor charts.)  
    1. I will help guide the inquiry circles, but I expect you to work as a team to solve your problems together. (While teams are working, walk around the room to facilitate as needed.)  

     

    After Inquiry Circles (10 minutes)   

    1. As we conclude our inquiry circles for today, each team’s Lab Director will lead the discussion about today’s results. Was the team able to synthesize the questions on their inquiry chart? What problems did the team encounter? How did the team resolve those problems? (After you have allowed the teams to gather their thoughts, have the Data Scientist share with the class.)  
    1. The Data Scientists will now share with the entire class one of their team’s synthesis statements. (Encourage teams to share how they developed their synthesis statements. If you saw a great example in action, encourage that team to share with the entire class.) 
  • Inquiry Circles

    OVERVIEW

    Teams will write synthesis statements for each inquiry question on their Inquiry Charts. You may need to make adjustments for teams who are still working to complete their Inquiry Charts.  

    Materials for the Inquiry Circles:

    Each team member needs:  

    • science notebook  
    • pencil  

      

    Each team needs:  

    • team Inquiry Chart

  • Guided Science Investigation

    OVERVIEW

    Learners play a timed game to identify acquired plant traits caused by external factors.

     

    GUIDING QUESTION

    How do external factors affect inherited traits in plants?

     

    BACKGROUND INFORMATION FOR THE TEACHER

    In addition to these environmental considerations covered in Day 2, there are other external factors that can impact plants and vegetation, including animal and human activity, and extreme weather events, such as flooding, snow and ice storms, heat waves, droughts, and wildfires. Extreme weather events have a direct impact on inherited plant structures and their functions. In this lesson, learners will engage in a timed game to test their skills in identifying acquired traits that are the result of these kinds of external factors.

    Materials for the Guided Science Investigation:

    Each team member needs: 

    • science notebook 
    • pencil 
    • Root Data Log 

     

    Each team needs: 

    • access to the “ISS Light Flight 1” PPT  

     

    Teacher needs: 

    • “ISS Light Flight 1” PPT 

    PROCEDURE

    Engage

    1. It’s game time! Today we’ll test your skills of observation and what you’ve learned about traits as you play for points using a special timed slideshow. The slideshow contains images of plants and vegetation that have been affected by external factors, such as weather events, or animal and human activity.
    2. Distribute a “Justify!” page to each team. Review the page together, instructing learners to work together within their teams to find any acquired traits in each image. Suggest they work quietly so that other teams cannot hear their discussion.
    3. Let teams know they have 30 seconds to make their observations on each image. (Teacher can user a timer or set timing on the PowerPoint presentation.)
    4. Add that they will earn 2 points for each acquired trait they identify. However, they also have to justify their answers to get the points—in other words, they need to explain why it is an acquired trait.
    5. Ask if there are any questions before beginning the slideshow.

     

    Explore

    1. When ready, begin the PowerPoint slideshow. Move between the teams and listen for their responses, but make no suggestions.
    2. Remind them to include all team members in the discussion.
    3. At the end of the slideshow, have everyone put their pencils away, letting them know they cannot add any more to their observations.

     

    Explain

    1. Explain that you will now show each image again and give each team a chance to share the acquired traits they found, along with their justification. If a team gets both the observation and justification correct, they will earn 2 points.
    2. However, let them know that another team can challenge their answer. For example, if a team misidentifies an inherited trait as acquired or if the justification is incorrect or insufficient, another team may challenge the answer (trait identification and/or justification) and provide the correct answer for 2 points (the results of the challenge will be at the discretion of the teacher).
    3. Allow enough time for teams to explain their observations and justifications for each image, as well as any challenges. Be sure to keep a tally of points earned.

     

    Elaborate

    1. Conclude the lesson by sharing information from the “Justify!” answer key.
    2. Highlight any spot-on observations or challenges you heard and offer clarification if needed to correct any misunderstandings.

     

     Evaluate

    1. During their discussions, did learners communicate a reasonable understanding of the acquired traits they observed in the images?
    2. Did learners make reasonable justifications?
    3. Are learners correctly using new science language in their communications (verbally or in writing)?
