The Scientific Method of my Invention Michelle 5B/18
Problem What can I make tohelp my mother and my father to get their Blackberry easily while driving.
Purpose • To find a way to make my parents get their Black Berry easily because I’m scared if my mother / father gets hit while driving if they pick up the phone call
What you already know • We need to answer the phone call • We need to answer BBM
Finding information • Incline plane is one of the simple machine principles. • If we put our belonging with more then 90°, our belonging will easy to drop • And if we put our belonging less then 90°, our belonging will not be easy to drop
Observation & Inference • Observation • My dad or my mom always findsdifficulties when they want to answer a call while driving • Inference • The bag / pocket is not a suitable place to keep the phone while driving
Hypothesis • If I make the BB holder then my parents can get their BB easier while driving.
Materials needed • Velcro • BB • Unused box • Paint • Fabric
Variables • The independent variable (What I change) :I change the angle of the box • The dependent variable (What I Observe) : When the BB fall down from the BB holder and how long the BB can stand • Controlled variables (What I Keep the Same) : The BB, velcro, unused box,paint and fabric
Procedure • 1. Prepare all the material and equipment • 2. Cut the unused box the same as the BB size • 3. Paint the unused box • 4. Wrap the fabric aroud the box • 5. Stick the velcro behind the box • 6. Put the BB in the middle of the fabric and the box • 7. Now try to put the BB holder in the toy car because when we try it in the real car and if the BB fall, the BB will be broken
Result and Data Analysis • 90°: the BB will be easy to fall • 50°: the BB will be hard to fall
Conclusion • So if the angle of the BB holder is less then 90°, the BB will not be easy to fall. And if the angle of the BB holder is 90° or more than 90°, the BB will be easy to fall.
