2. 1. Improve your project in the following
O - Function.
For charging a battery.
O - Weight.
220 gram.
O - Strength.
Material is iron then
it can withstand a lot.

3. O - Appearance
We paint color.
O - Ease of use
Acting clamp that can be used
and stored easily.

4. 2. Find out the key features of your product by
answering the following questions:
O - What are the problems that your product
can solve?
We want to take advantage the
winds through us useless while driving.
O - What are the main benefits or
advantages that your product has?
The main benefit is charging a
battery.

5. Compare with product with similar
products.

6. Topic for Our Product on Reason
compariso product the market
n
Time for Longer Faster - Products on the market used electric
charging power directly.
- Our product is longer because it
depending on the price of the motor,
Weather, The speed of
the motorcycle.
Price cheap expensive -Our product is made from
materials is used.
Strength Stronger Less -Our structure product made from
Than strong. steel
similar -the product from the market made
product. from plastic. It can impede force is
less.

7. 3. For each key feature of your
product, carry out the experiment
based on the scientific method:
Our experimental results was completed.
It shows appropriate sized blade.
