Year 3 Design and Technology

Making a moving monster (Mechanisms)

Pupils will identify objects that use a lever or linkage mechanism, consider what a user might like or dislike for a new toy, make linkage mechanisms with card, identifying the input and output, investigate how changes to the mechanism change how it moves, use diagrams to show ideas for a product, choose between different ideas and explain the reasons, carry out a simple survey of others’ opinions, cut and join materials accurately, decorate a product with a good quality finish and evaluate my product against the design criteria.

1. Pivots, levers, linkages-How do levers and linkages help everyday objects move? To identify levers and linkages in everyday objects.

2. Making linkages- How can I create a linkage mechanism that creates movement? To investigate how to make linkage mechanisms

3. Designing my monster- How can I design a moving monster toy that meets the needs of a user?  To use diagrams and surveys to design a moving monster toy.

4. Making my monster-How can I cut and join materials to make a monster with a working linkage mechanism? To use suitable cutting and joining techniques to make a toy with a linkage mechanism.

National Curriculum Objectives

Design

• Use research and develop design criteria to inform the design of innovative, functional, appealing products that are fit for purpose, aimed at particular individuals or groups.

• Generate, develop, model and communicate their ideas through discussion, annotated sketches, cross-sectional and exploded diagrams, prototypes, pattern pieces and computer-aided design.

Make

• Select from and use a wider range of materials and components, including construction materials, textiles and ingredients, according to their functional properties and aesthetic qualities.

• Select from and use a wider range of tools and equipment to perform practical tasks [for example, cutting, shaping, joining and finishing], accurately.

Evaluate

• Investigate and analyse a range of existing products. 

• Evaluate their ideas and products against their own design criteria and consider the views of others to improve their work.

Technical Knowledge

• Understand and use mechanical systems in their products, for example, gears, pulleys, cams, levers and linkages.

Product packaging (Structures)

Pupils learn to investigate and analyse a range of existing packaging products, identifying shapes, form and function, evaluate what makes good packaging and what shapes suit which products,design, make and evaluate product packaging, following a design criteria, use CAD software (Sketchpad) to create 2D shapes that form the net of 3D shapes, including the tabs, give and receive feedback and identify errors in nets to help suggest improvements, cut, fold and stick the parts of a net together to make a 3D shape, use ribbing to strengthen packaging and decorate packaging with an intentional design that shows its function.

1. Exploring product packaging- How are 3D shapes used to make packaging for different products?- To evaluate how 3D shapes are used in product packaging.

2. Using nets- How can I design a net that folds into a 3D shape for packaging? To design nets for 3D product packaging.

3. Reviewing designs-How can I test and improve my net design to make effective packaging?- To review and improve net designs for packaging.

4. Making 3D packaging-How can I use a net to make packaging for a healthy snack? To make 3D structures to package a healthy snack.

5. Decorating and evaluating- How can I decorate my packaging to meet a design brief and evaluate how well it works?- To use a design brief to finalise and evaluate packaging.

Technical Knowledge

• Apply their understanding of how to strengthen, stiffen and reinforce more complex structures.

Cookery-Eating Seasonally - Seasonal Tart

1. What foods do we import?- To explain why food comes from different places around the world.

2. What effects does importing food have on the environment?- To explain the benefits of seasonal foods.

3. How can we cut and peel vegetables safely?- To develop cutting and peeling skills.

4. What words can we use to decribe different tastes?- To evaluate seasonal ingredients.

5. How can we create a mock-up of our dish?-To design a mock-up using criteria.

6. How can we improve our dish?- To evaluate a dish.

National Curriculum Links

• Understand seasonality, and know where and how a variety of ingredients are grown, reared, caught and processed.

• human geography, including: types of settlement and land use, economic activity including trade links, and the distribution of natural resources including energy, food, minerals and water.

• Select from and use a wider range of tools and equipment to perform practical tasks [for example, cutting, shaping, joining and finishing], accurately. 

• Prepare and cook a variety of predominantly savoury dishes using a range of cooking techniques

• Select from and use a wider range of materials and components, including construction materials, textiles and ingredients, according to their functional properties and aesthetic qualities.
