Design and make a doodler

Design

• Identifying factors that could be changed on existing products and  explaining how these would alter the form and function of the product. 

• Developing design criteria based on findings from investigating existing  products. 

• Developing design criteria that clarifies the target user.

Make

• Altering a product’s form and function by tinkering with its configuration. 

• Making a functional series circuit, incorporating a motor. 

• Constructing a product with consideration for the design criteria.  

• Breaking down the construction process into steps so that others can make  the product.

Evaluate

• Carry out a product analysis to look at the purpose of a product along with  its strengths and weaknesses. 

• Determining which parts of a product affect its function and which parts affect its form. 

• Analysing whether changes in configuration positively or negatively affect  an existing product. 

• Peer evaluating a set of instructions to build a product.

Technical Knowledge

• To know that series circuits only have one direction for the electricity to flow. 

• To know when there is a break in a series circuit, all components turn off. 

• To know that an electric motor converts electrical energy into rotational  movement, causing the motor’s axle to spin. 

• To know a motorised product is one which uses a motor to function.
