Design and Technology – Rain Gauge Project
My target level is..............
Introduction
In this project you will have the opportunity to design and make a prototype
Rain Gauge. Before starting you will need to think about how a Rain Gauge
works. The current Met Office rain gauges are the Munro R102 and the
standard 5 inch check gauge.
This design guide will help you through your design process. Sketch, draw, write
down in a neat fashion ideas and thoughts as you work though this guide. You
will need these notes to help you produce your final design presentation.
Situation: Measuring the amount of rain accurately is not easy!

Must be stable.
What unit is used for rain fall?
Will it be a manual gauge or record rainfall automatically?
Where will the water go?
Think about the location of the rain gauge in a typical garden. How will its
location effect any rain falling into/on to it?
Think about wildlife, could they be a problem?
It will need to recorded very small amount of rain, how?
Is it easy to see or work out the rain fall?
Will it need a power source? How long will it last?
Any electrical circuit will need to be kept dry / waterproof, how?
How will you know if your screens design is effective?
Is your design effective?

Before starting to design it is a good idea to list down all the requirements for the rain
gauge and explain the reasons for each requirement. This is known as a specification, we
have started for you. Think of some more, include who will be the user of the screen.
Have you written down a list of the
requirements that the design must
satisfy?
Does the list include at least five
different types of requirement? For
example: what it looks like, the
needs of the person using it, cost,
safety, size, how it will work,
materials available and tools
required.
Have you taken users' views into
account? Does the list include the
things that limit what can be
made?

Can you show that the list
considers the needs of the people
who will use the product?
8
Have you explained why each is
important?
9
Are the features of similar products
mentioned in the specification
10
Does the explanation say how
similar products look and work, and
what this means for the product?
