Series and parallel circuits. Basic notes and a quiz
Watch the video showing series and parallel circuits with two light bulbs. Read over your class notes and get help from the text book if you need to.
Series and Parallel circuits
In a series circuit the components are connected in such a way that the current flows from one component to the other all the way round the circuit. In a parallel circuit the current branches and can follow more than one pathway
What happens in a series circuit when a bulb is removed?
What happens in a parallel circuit when a bulb is removed?
Think about the brightness of the bulbs
then try the quiz. Make sure you click the submit button when you finish. Finally, the video is very boring. Make your own video to demonstrate the difference between series and parallel circuits
Your Science Exam for 2015 will take place during class time on Thursday and Friday. You will need to revise topics covered during the year. To begin with please familiarise yourself with the content from the Moving About, Structure of Matter and Electricity topics.
Look at the tests. These are the papers you completed earlier in the year.
Check that you are familiar with the material and can answer the questions by looking at the mark schedules.
Come prepared to ask for help with any aspects of the topics you need help with.
The end of year exams are looming. It is important that you finish the year strongly and don’t switch off early. Read through the notes and watch the videos on acids and bases before attempting the questions at the end
We have studied the reactions of acids with:
We have used word equations to produce fully balanced chemical equations in three steps. For a little more information on this process have a look at this post about the space shuttle being blasted into orbit on the back of a huge pop test.
the basic word equations we use are:
acid + base —–> salt + water
acid + metal —–> salt + hydrogen
Acid + carbonate —–> salt + carbon dioxide + water
Use these word equations to answer the questions below.
