Weather Exploration

XPLORE: What Is the Weather Like? Preparation • Read the teacher facilitation notes. • Watch the setup video for activity context. • Create a teacher exemplar for the Claim-Evidence (CE) response and the student handout. • Print and organize all materials needed for the activity. • Prepare index cards for key vocabulary terms introduced during the activity. Facilitation • Introduce the phenomenon question to guide student exploration. • Pre-teach and define key vocabulary. Encourage use of vocabulary during group discussions with sentence starters. • Model a think-aloud to demonstrate how students should complete the activity in small groups. • Post an anchor chart to record student observations and responses throughout the activity. • Create a Claim and Evidence chart. Prompt students to share their thinking and back up their claims with evidence from the investigation Formative Assessment • Use a kid-watching tool to document anecdotal notes of student engagement and reasoning. • Select and print a question from the Open-Ended Response Assessment to use as an Exit Ticket.

Standards Alignment (Common Core + Next Generation Science Standards)

Next Generation Science Standards (NGSS)

2-ESS2-1: Develop a model to represent the shapes and kinds of land and bodies of water in an area.
2-ESS2-2: Describe weather conditions through observations (temperature, wind, clouds, precipitation).

Common Core State Standards (CCSS) – Literacy in Science

CCSS.ELA-LITERACY.RI.2.1: Ask and answer questions to demonstrate understanding of key details in a text.
CCSS.ELA-LITERACY.SL.2.1: Participate in collaborative conversations with diverse partners about grade 2 topics and texts with peers and adults in small and larger groups.
CCSS.ELA-LITERACY.W.2.8: Recall information from experiences or gather information from provided sources to answer a question.

Learning Objectives

By the end of the lesson, students will be able to:

Use key weather-related vocabulary to describe the weather accurately (e.g., temperature, cloud, rain, wind).
Observe and record weather phenomena using simple scientific tools and senses.
Formulate claims about the weather conditions and support them with evidence collected during the activity.
Collaborate respectfully in small groups, using sentence starters to share observations and ideas.
Reflect on learning by responding to an open-ended question about the weather.

Materials Needed

Teacher exemplar Claim-Evidence (CE) response sheet
Student Claim-Evidence handouts
Index cards with key vocabulary: temperature, cloud, rain, wind, sunny, cloudy, stormy
Anchor chart paper and markers
Simple weather observation tools (thermometer, wind sock or paper pinwheel, rain gauge or plastic bottle to measure rainfall)
Kid-watching observation tool for anecdotal notes
Exit Ticket question printed for distribution

Vocabulary Sentence Starters for Student Use

"I notice that the ________ is __________."
"I think it is ________ because I see __________."
"My evidence for the weather being __________ is __________."
"The temperature feels _________, so I believe __________."

Lesson Procedure

1. Introduction (5 minutes)

Phenomenon Question:
"What Is the Weather Like Today?"
Engage students by asking, "How would you describe today’s weather to someone who can't see outside?"
Briefly introduce key vocabulary by showing index cards and defining words aloud. Use student-friendly definitions and examples.
Encourage choral repetition for each vocab word to reinforce pronunciation.

2. Modeling & Think-Aloud (5 minutes)

Display the teacher exemplar Claim-Evidence response for a weather observation.
Model a think-aloud while describing today’s weather and filling out the CE chart:
- Make a claim (e.g., "I claim it is cloudy today").
- Provide evidence (e.g., "The sky is covered with gray clouds, and it feels cooler than yesterday").
Emphasize how evidence comes from what they observe using their senses and tools.

3. Small Group Exploration (12 minutes)

Divide students into 4 groups of 3-4.
Distribute student CE handouts, vocabulary cards, and weather tools to each group.
Guide groups with sentence starters to make claims and support with evidence.
Circulate and use the kid-watching tool to document student participation and reasoning.
Post an anchor chart titled “Our Weather Observations” where each group contributes their claim and evidence.

4. Group Discussion and Reflection (5 minutes)

Invite each group to share one claim and supporting evidence from their CE chart.
Reinforce using vocabulary and sentence starters.
Add key student responses to the anchor chart.

5. Formative Assessment / Exit Ticket (3 minutes)

Distribute the printed open-ended response exit ticket question:
“Describe today’s weather. Use at least two vocabulary words and explain what evidence helped you decide.”
Collect responses to assess each student’s understanding.

Differentiation Strategies

For Emerging English Learners:
Provide sentence frames with visual icons and partner students with peers fluent in vocabulary use.
For Advanced Students:
Challenge them to incorporate observations about how weather changes throughout the day and speculate reasons.

Teacher Reflection & Notes

Review anecdotal notes for insights on student engagement and misconceptions.
Consider revisiting vocabulary and claim-evidence framework in future lessons to build scientific reasoning skills.
Reflect on group collaboration dynamics and scaffold communication as needed.

This lesson plan combines hands-on exploration with literacy integration within the science domain, engaging second graders in meaningful observation and evidence-based thinking directly tied to NGSS and Common Core standards. The guided Claim-Evidence framework fosters critical science practices and language development, making weather investigation accessible and fun.
