1. Improve your project in the following
O - Function.For charging a battery.
O - Weight.220 gram.
O - Strength.Material is iron thenit can withstand a lot.
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.
Topic for comparis
on
Our produc
t
Product on the market
Reason
Time for charging
Longer Faster - Products on the market used electric 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 Than similar product.
Less strong.
-Our structure product made from steel-the product from the market made from plastic. It can impede force is less.
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.
