Ice Cream Setup

Overview

• Year group: 4
• Duration: 60 minutes
• Class size: 30
• Unit: Chill Out: Science Ice Cream (Lesson 4 of 6)
• Topic: Setting up the ice cream experiment
• Curriculum Links:
  • National Curriculum KS2 Science (Years 3 & 4): Working scientifically – making careful and systematic observations; recording data; using standard units of measure and appropriate equipment.
  • Mathematics Programme of Study: Measurement – using scales, measuring volumes and weights.

Learning Objectives

By the end of the lesson pupils will:

• Accurately measure ingredients using standard units (ml, g).
• Demonstrate correct use of measuring equipment such as measuring spoons, jugs, and kitchen scales.
• Follow a step-by-step procedure to prepare an ice cream mixture for the experiment.
• Understand why accurate measurement and preparation are crucial for a fair scientific investigation.

Success Criteria

• Pupils accurately measure ingredients within ±5% of the target amount.
• Pupils follow the preparation steps independently or with minimal adult support.
• Pupils can explain why measuring carefully is important in an experiment.

Resources

• Bowls or sealable plastic bags for ice cream mixture
• Measuring spoons (ml) and jugs
• Digital or kitchen scales (g)
• Ingredients per group (cream, sugar, vanilla essence, salt, crushed ice)
• Worksheets for recording measurements and method steps
• Whiteboard and markers
• Visual aids/poster showing measurement units and equipment
• Timer or clock

Lesson Structure

1. Starter (10 minutes)

Engage and Recap

• Begin with a quick discussion: “Why is measuring important in cooking and science?”
• Recap last lesson’s findings on what affects ice cream’s texture and freezing.
• Show students the ingredients and measuring equipment, naming each.

Activity:

• Quick quiz: “Name the unit of measurement for…” (volume - ml, weight - g)
• Demonstrate using a jug and scale, emphasising precision and reading the scales at eye-level.

2. Main Activity (40 minutes)

Setting up the Experiment

• Organise pupils into groups of 4-5 for practical work (6 groups total).
• Distribute ingredients and equipment. Each group receives a worksheet with:
  • Ingredient measurements (e.g., 120 ml cream, 2 tsp sugar, 1 tsp vanilla essence).
  • Step-by-step method for mixing ingredients.

Teaching points during the activity:

• Proper use of measuring spoons and jugs: level off sugar, fill to line on jug, and spoon vanilla carefully.
• Use scales for the salt and crushed ice: encourage zeroing the scales.
• Emphasise hygiene: wash hands before and after handling ingredients.

Activity instructions:

1. Measure and pour cream into bag or bowl.
2. Add sugar and vanilla essence.
3. Mix gently but thoroughly until sugar dissolves.
4. Prepare the outer bag/container with ice and salt for freezing (to be used in the next lesson).

Teacher’s Role:

• Circulate, observing accuracy and offering guidance.
• Ask probing questions: “How do you know you have the right amount?”, “What do you do if you add too much sugar?”
• Use assessment for learning—note groups’ measurement skills for next steps.

3. Plenary (10 minutes)

Reflect and Discuss

• Groups share how they ensured accuracy in measuring ingredients.
• Ask: “What might happen if we don’t measure correctly?”
• Highlight the importance of following steps for fair scientific testing.

Whole-Class Discussion:

• Connect measuring skills to real-life science and cooking.
• Encourage pupils to think ahead: “What will happen next lesson when we freeze the mixture?”

Quick Write:

• Pupils write one sentence about why measuring carefully matters in experiments.

---

Assessment

• Formative – observation notes on pupils’ measuring technique and adherence to instructions.
• Worksheet completion – recorded measurements and method steps checked for accuracy and understanding.
• Oral questioning during plenary to assess conceptual understanding.

---

Differentiation

• Support:
  • Provide visual measuring guides and step prompts for SEN pupils.
  • Assign peer buddies for additional support during practical work.
• Challenge:
  • Ask advanced learners to estimate and then verify volume/weight.
  • Encourage them to suggest improvements to the method or predict effects of measurement errors.

---

Cross-Curricular Links

• Maths: Measurement skills, reading scales, working with units and estimates.
• English: Writing clear instructions, using precise language.
• PSHE: Teamwork and responsibility during group work.

---

Safety and Management

• Ensure handwashing before and after handling food ingredients.
• Care when using scales and sharp utensils if needed.
• Clear spills immediately to avoid slipping hazards.

---

Teacher Notes

• Prepare all ingredients measured roughly before the lesson for efficiency, but allow pupils to do all the measuring.
• This lesson forms the foundation for experimental design; accuracy here is critical for valid results next sessions.
• Encourage curiosity by asking “What do you think salt does to ice?” to build scientific thinking for future lessons.

By following this detailed plan, teachers will create an interactive, hands-on experience that develops practical skills, scientific thinking, and collaboration, grounded in UK educational standards.
