**Objectives:**
1. Understand the three primary states of matter: solids, liquids, and gases.
2. Identify and describe characteristics and examples of each state of matter.
3. Explain the processes of changing states (melting, freezing, condensation, and evaporation).
**Materials Needed:**
- Ice cubes
- Beakers or small bowls
- Water
- Balloons

- Chart paper
- Markers
- Science journals
**Lesson Duration:** 60 minutes

### Lesson Outline:
**Introduction (10 minutes):**
1. Begin with a brief discussion about matter and its importance in everyday life.
2. Introduce the concept that matter exists in different states: solid, liquid, and gas.
3. Show an example of each state: an ice cube (solid), water (liquid), and air (gas, inside a balloon).
**Activity 1: Characteristics of States (15 minutes):**
1. Divide the class into small groups and provide each group with a set of materials (ice cube, cup of water, and a balloon filled with air).
2. Ask students to observe and record the characteristics of their samples in their science journals.
- Solid: keeps its shape, hard
- Liquid: takes the shape of its container, flows
- Gas: invisible, fills the whole container
3. As a class, discuss their observations and write the key characteristics on the whiteboard.
**Activity 2: Changing States of Matter (20 minutes):**
1. Conduct a demonstration of melting and freezing using ice and a hot plate or stove.
- Show what happens when ice (solid) melts into water (liquid).
- Discuss how water (liquid) freezes into ice (solid).
2. Explain the processes of condensation and evaporation.
- Boil water briefly and catch the steam on a cold surface to show condensation.
- Discuss evaporation in everyday life (e.g., drying clothes).
3. Use chart paper to create a diagram of the water cycle, emphasizing the states of matter transitions.
**Discussion and Q&A (10 minutes):**
- Engage students in a discussion about where they see examples of melting, freezing, evaporation, and condensation in their daily lives.
- Open the floor for any questions and provide clarifications.
**Wrap-Up Activity (5 minutes):**
- Ask students to draw and label an example of a solid, liquid, and gas in their science journals.
- Encourage students to write a short sentence about each state of matter based on what they learned.
**Conclusion:**
- Summarize key points.
- Emphasize the importance of understanding states of matter and their transformations in daily life.
**Homework:**
- Assign students to find one item at home for each state of matter and write a short description of it in their science journals.
---
**Assessment:**
- Participation in group activities and discussions.
- Observations and notes in science journals.
- Homework assignment.
**Extension Activities:**
- Experiment at home with freezing and melting different liquids (like juice or milk) and note the differences.
- Create a poster board that visually represents the states of matter and the process of changing states.

**Standards Alignment:**
- This lesson aligns with the curriculum expectations for Year 5 science and explores the principles of matter, its states, and phase changes. It fosters observational skills, critical thinking, and the ability to describe scientific concepts clearly.
