Modelling your toothbrush idea.
Today you will model your developed design idea using blue foam. This is an excellent material for modelling as you can sculpt designs using general equipment such as files and sand paper
You will all be provided with a toothbrush to model with and it is up to you how you complete this.
Do you model around it?

GCSE Design Technology – Toothbrush redesign for an elderly person
Modelling your toothbrush idea.
You may have noticed on the video the man used a template to cut around. This will ensure it is accurate. YOU WILL BE DOING THE SAME.
The cardboard template needs to be the same size and simply the outer shape.
The cardboard template will be attached to the blue foam using double sided tape.
Before you can START you need to know the thickness of your toothbrush(as well as length and width) so that it can prep and cut for you.
If the department has this resource use this slide.
