Exploring Solid Objects

Overview

• Duration: 30 minutes
• Class size: 10 students
• Unit: Hands-On Learning Adventure (Lesson 1 of 7)
• Age group: Year 1 (5-6 years old)
• Subject: Other (Science-focused hands-on activity)

National Curriculum Alignment

This lesson aligns with the Science Programmes of Study for Key Stage 1, specifically focusing on:

• Year 1: Everyday Materials (National Curriculum for England, 2014)

  • Identify and name a variety of everyday materials, including wood, plastic, glass, metal, water, and rock.
  • Describe the simple physical properties of a variety of everyday materials.
  • Compare and group together a variety of everyday materials on the basis of their simple physical properties.

• Scientific Enquiry (Working Scientifically - Years 1 & 2)

  • Ask simple questions and recognise that they can be answered in different ways.
  • Use observations and ideas to suggest answers to questions.
  • Gather and record data to help in answering questions.

Learning Objectives

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

1. Identify solid objects in the classroom environment.
2. Describe basic properties of solids (shape, texture, size).
3. Sort and categorise objects based on their physical properties.
4. Demonstrate collaborative skills through group discussion and sorting activity.
5. Begin to use scientific vocabulary such as solid, shape, texture, smooth, rough, and hard.

Resources Needed

• Collection of everyday solid objects in various shapes and textures (e.g., wooden block, plastic toy, metal spoon, rubber ball, fabric pieces, cardboard box)
• Sorting mats labelled with categories: Shape, Texture, Size
• Visual aids/posters showing materials vocabulary and property descriptors with pictures
• Large tray or box to hold objects
• Whiteboard and coloured markers
• Worksheet with simple drawing and labelling activity (optional, for assessment)

Lesson Structure

1. Introduction & Engagement (5 minutes)

• Greeting and settle students.
• Present the lesson title and explain the fun goal: "Today, we are going on a treasure hunt to find solid objects we can hold and learn what makes them special!"
• Show a few example objects and ask:
  • "Can you tell me what this object is?"
  • "What shape does it have?"
  • "How does it feel when you touch it? Smooth or rough?"
• Emphasise key vocabulary: solid, shape, texture, hard, smooth, rough. Write these on the board with icons illustrating meaning.

2. Exploration and Identification Activity (10 minutes)

• Hand out the tray or box of objects.

• Pupils work in small pairs to:

  • Explore objects by touching and observing.
  • Name the objects out loud and describe one property (shape or texture).

• Circulate and ask probing questions:

  • "Is it round or square?"
  • "Does it feel soft or hard?"
  • "Can this object change shape if you hold it tight?" (No! Because it’s solid.)

• Encourage use of scientific vocabulary.

3. Sorting Activity (10 minutes)

• Introduce sorting mats with clear pictorial cues and labelled headings: Shape, Texture, Size.

• Pupils return objects to the centre and work together as a class or in two groups to sort objects into these categories.

  • For Shape: round, square, irregular
  • For Texture: smooth, rough
  • For Size: small, medium, large

• Prompt group discussion about why objects go where.

• Use questioning to develop reasoning:

  • "Why do you think this object is rough?"
  • "Are all round objects smooth?"

4. Reflection and Recap (5 minutes)

• Gather the class back together to talk about what they learned.
• Ask questions:
  • "What is a solid object?"
  • "Name one object you liked and tell us how it feels."
• Summarise key vocabulary and concepts.
• Optional: Quick drawing task where pupils sketch one object and label it with shape or texture words learned today.

Assessment

• Formative: Teacher observations during paired exploration and sorting activity to assess understanding of solidity and object properties.
• Oral: Use questioning throughout to gauge vocabulary use and descriptive skills.
• Optional: Review completed worksheet/drawing for correct identification and simple description of an object.

---

Differentiation and Support

• For lower ability learners: Provide pre-sorted examples to model groups before the activity. Use paired support with a more confident peer.
• For higher ability learners: Challenge to explain why some objects might belong to more than one category (e.g., a small rough object). Introduce the word “hard” as an additional property.
• Sensory support: Include objects with varied textures and shapes for tactile engagement.

---

Extension Ideas (If time allows or for follow-up lessons)

• Introduce other states of matter by comparing solid objects to liquids (e.g., water) through simple safe demos.
• Create a “Material Detective Book” for each pupil to collect photos or drawings of solids they discover outside class.
• Use building blocks to construct 3D shapes and discuss their solidity and structure in more depth.

---

Teacher’s Notes

• Prepare all objects beforehand to ensure safety and appropriateness for this age group. Avoid small objects that could be choking hazards.
• Emphasise vocabulary repetition and encourage full sentences to build language skills.
• Maintain positive classroom management during hands-on activities by clear instructions and roles (e.g., “explorer,” “sorter”).

This plan offers an engaging and curriculum-aligned introduction to solid objects, developed specifically for Year 1 learners, intertwining scientific enquiry with tactile discovery, observation, and collaborative learning.
