For our last piece of the puzzle before we begin reviewing for exams, we are going to take a look at some of the applications of what we have been learning so far.  You can choose one of the questions from the list below (or come up with your own and clear it with Mrs D) then find out the answer, and share it with the group in a meaningful way.  This could be a poster, a video, a model, a powerpoint, a speech – whatever you feel is appropriate to convey the information.

  • How is electrical charge associated with nervous impulses (signals) passing along neurones?
  • What is the difference between AC  and DC?
  • A time traveler from 100 AD arrives at ISM.  Explain to this person the dangers of electricity.
  • How does an electric motor work?
  • What is a fuse and what does it do?  Why are there different kinds of fuses?

Tim and Moby at brainpop have lots to say on this topic.  Here are links to one, two, three of their videos.

Here is Mr Dickinson’s “soldier’s marching” analogy: Electric Circuit

This site has really good, easy to follow information on all matters concerning electric circuits.  We will use this online circuit construction site as well.  And watch this: YouTube Preview Image

Lightning by -Qualsiasi on flickr

Start by watching this brainpop video.   And here is our old friend Bill Nye‘s explanation.

Here are a couple more links to some useful information:- this one from enchanted learning and this one from science made simple.  

Now can you explain how lightning happens?

Another useful bit of information.  And download this animation to help you as well.
