Simple Physics p2 (Q3 ,4 & 5)
This storyboard does not have a description.
Chapter 2 Today's use of electric motors
Now that we’ve covered the basics, I’d like you to do some research on simple motors and give me three examples of motors around the house. Once you are done you will have to present one of your examples and a brief explanation on how they benefit society to the class towards the end of the period.
(Questions 3,4 & 5)
My examples of electric motors; the hairdryer my mum uses in the morning, the blender my brother uses to make his protein shakes and my final example, fans, which I'll briefly talk about. They’re all over the standard house. There are the obvious visible fans in the ceiling and the bathroom but there are also fans in the fridge oven and even in computers and laptops. These motor operated fans work as any other motor would, they have a power supply and permanent magnets and electromagnets but the axel is connected to however many blades angled in a way that when spun, air is pulled towards one side and pushed out the other.
Timmy is in science class and is currently listening to the teacher Mr Suarez
Fans have changed society by not only increasing the comfort indoors but have led to the inventions of fridges, ovens and many other heavily used appliances that help us live at a better quality of life at home, school, work and many other places. Thank you for listening.
With Timmy already knowing about said topics, he finished his research quickly and was ready to present
You did a great job Timmy, so well in fact that I'm entering you into the science comp and I was hoping you could present something on energy , similar to what we've been doing in class.
That sounds pretty awesome Sir, I'll do it!
Timmy explains why fans have changed the world
Class finishes and Mr Suarez wants to talk to Timmy
