Ice Cube Challenge Lab ✨ cross-curricular
Teacher: TeacherAI | Grade: 2 | Subject: Reading/ELA, Science, Technology | Duration: 60 minutes
📝 Description: Students read science texts about matter changes, test heating and cooling with ice cubes, and evaluate digital sources for accuracy.
Standards
- 2.RI.7 (Explain how specific images contribute to and clarify a text)
- 2.RI.8 (Describe how reasons support specific points the author makes in a text)
- 2-PS1-3 (Make observations to construct an evidence-based account of how an object made of a small set of pieces can be disassembled and made into a new object)
- 2-PS1-4 (Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot)
- TECH.2.3.b (Evaluate digital content for accuracy and reliability)
Learning Objectives
Students will be able to:
- Identify how images in science texts help explain heating and cooling changes
- Describe reasons authors give to support points about matter changes
- Record observations of ice melting and water freezing using counting manipulatives
- Argue with evidence whether heating and cooling changes can be reversed
- Evaluate simple digital content about matter for accuracy using a checklist
Supplies Needed
- Tablets or Chromebooks
- White paper
- Pencils
- Counting manipulatives (cubes or bears)
- Ice cubes (2 per student)
- Small plastic cups
Lesson Structure
Opening (5 minutes)
Show students two ice cubes. Place one in a cup and one on a warm surface. Ask: "What do you predict will happen? How could we find out if this change can be reversed?" Record predictions on whiteboard.
Main Activity (50 minutes)
Step-by-step instructions:
- Digital Research Phase (15 minutes): Students use tablets to find one article about ice melting or water freezing. Using the Digital Content Checklist, they evaluate if the source shows real photos, gives clear explanations, and comes from a reliable website. Students mark "thumbs up" or "thumbs down" for each criterion.
- Text Analysis (10 minutes): Display a simple science text about states of matter on tablets. Students identify one image that helps explain the text and one reason the author gives for why ice melts. Have students turn and talk with partners about their findings.
- Ice Observation Setup (5 minutes): Give each student two ice cubes in separate cups. Students predict using manipulatives - place cubes in a line to show "how much water" they think will result. Record prediction on observation sheet.
- Heating Test (10 minutes): Place one cup in warm area, keep one in cool area. Every 3 minutes, students use manipulatives to model the amount of melting they observe. They arrange cubes to represent solid ice vs. liquid water amounts.
- Evidence Collection (5 minutes): Students draw before/after pictures and write one sentence about what they observed. Guide them to note which changes happened faster and why.
- Reversibility Challenge (5 minutes): Ask: "Can we turn the water back into ice? What evidence do we have?" Students discuss in pairs, then share reasoning with class. Explain how freezers can reverse this change, connecting to the concept of reversible changes.
Closing (5 minutes)
Students share one thing they learned about heating/cooling changes and one way images helped them understand the science text better.
Quick Check: "Show thumbs up if ice melting can be reversed. What made your digital source trustworthy? How did pictures help you understand the text?"
Formative Assessment
During the lesson, look for:
- Students correctly identifying specific images that clarify text meaning during digital research
- Accurate use of manipulatives to represent solid and liquid amounts during observations
- Appropriate evaluation of digital sources using the provided checklist criteria
Differentiation Strategies
Support for Struggling Students:
- Pair with stronger readers during digital research phase
- Provide sentence starters: "The ice changed because..." and "This picture shows..."
- Use fewer manipulatives (5-10 pieces) to represent changes
Challenge for Advanced Learners:
- Research examples of non-reversible changes (like cooking eggs) and compare to ice melting
- Create their own simple digital content about matter changes with drawings and explanations
- Predict and test melting times for different ice cube sizes
ELL/ELD Support:
- Pre-teach vocabulary: melt, freeze, solid, liquid, evidence, reverse
- Encourage drawing and visual representations alongside written observations
- Provide native language resources for matter vocabulary when available
