Year 3 Week 2 Day 1

Plan: Science Bug Year 2/P3 Unit: Uses of Materials Date: 04/04/16 School Name: Demo Account Teacher: Don Ashlone Class: Class 5

Uses of Materials - Unit overview

Summary In this unit children will name, identify and hunt for everyday materials including wood, metal, plastic, glass, rubber, brick, rock, paper, fabric and card. They will list properties of different materials such as hardness, strength, flexibility and shininess. They will learn that the properties of materials are important to the object they are made from. They will identify suitable and unsuitable materials for different objects and will be able to explain why. Working Scientifically, children will classify materials sorting them into groups in a variety of ways. They will use reference materials to find out some fascinating facts about a type of material. They will compare the strength of different types of paper predicting which will rip when pulled by their hands. They will learn what absorbency means and explore the absorbency of different types of materials. They will examine different ways to record results and select an appropriate way to record the results of an investigation about waterproof materials. They will apply the findings from these investigations to design a nappy.

Expectations

By the end of this unit: On Track Children who are working at the expected standard will have named and identified everyday materials including wood, metal, plastic, glass, rubber, brick, rock, paper, fabric and card. They will have understood different properties such as hardness, strength, flexibility and shininess, and will have compared the properties of different materials. They will have identified suitable and unsuitable materials for different objects and will have explained why they are unsuitable.

Children will have sorted materials into groups in various ways and will have explained their groupings. They will have used reference sources to help produce a fascinating facts sheet about a type of material. They will have compared the strength of different types of paper, predicting which will rip when pulled by their hands. They will have chosen an appropriate way to record the results of an investigation about waterproof materials. Exceeding Children who have exceeded the expected standard will have named and identified a wider range of materials including different types of metals and woods. They will have identified which material is the best for an object stating logical reasons. They will have made predictions relating to the relative strength of papers and will have explained their thinking and can order results. Working Towards Children who are emerging will have named and identified some everyday materials. They will have found objects made out of the same material as a given sample. They will have sorted materials into two groups often using opposites to do this, e.g. soft and hard. They will have investigated the strength, absorbency and waterproof properties of different materials and will have described what they observed.

Lesson Summary Uses of Materials 1 Children examine a selection of materials and list as many as they can. The teacher plays ʻAltogether, show me,ʼ with the class, identifying named materials from the selection. Children search for materials in their classroom and sort selections of materials into categories of their choosing. The teacher asks children simple questions about their choices and about similarities and differences between materials. Children then select a material and describe its properties for others to identify.

Uses of Materials 2 Children name materials around the classroom and state why they think objects are made from the materials that they are made from. The teacher shows a slideshow of objects that can be made from different materials and children answer questions on the suitability of the materials. In pairs, children list and test materials which could make

The teacher shows children pictures of objects made from unsuitable materials and discusses other unsuitable materials for objects.

Uses of Materials 3 Children explore the properties of cornflour slime. They read facts, choose the fact they found most interesting and explain why. They produce a 'lift-the-flap' style information sheet about a material of their choice and complete a quiz about the suitability of materials.

Uses of Materials 4 Children test the strength of different materials by pulling strips of the materials to discover how easily they rip. The teacher explains what Newtons are and shows children example measurements so they can determine the best method for recording data. Children carry out an experiment, combining water with absorbent materials and observing the results. They then test the absorbency of a variety of materials by wiping water from a metal tray. They record their results and then share them with the class.

Uses of Materials 5 The teacher asks children questions about waterproof clothing before challenging them to improve nappy waterproofing. They drip water onto a selection of materials to discover which one is least absorbent. They record their results and then share them with the class.

Uses of Materials 6 Children continue their challenge to design a perfect nappy. The teacher gives groups of children a nappy and asks them to disassemble them and to create a list of the component materials. Children select different materials based on their previous investigations to design and make nappies. They evaluate their nappies on durability, absorbency and waterproofing then give presentations on their nappy designs.
