1. Duck LastWind Vane 2. 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. 3. O - AppearanceWe paint color.O - Ease of useActing clamp that can be usedand 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 similarproducts. 6. Topic for OurProduct onReasoncomparisoproductthe marketnTime for Longer Faster - Products on the market used electriccharging power directly. - Our product is longer because it depending on the price of the motor, Weather, The speed of the motorcycle.Pricecheapexpensive-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 experimentbased on the scientific method:Our experimental results was completed.It shows appropriate sized blade. 8.
