scientific Lab Report:Connecting 2 circuits

Aim :

(what is the purpose of this experiment -in just a few words: To (observe /check /identify) :To observe what happens when you connect two different circuits ,to  make one circuit.

Hypothesis/prediction:   (what think that will happen and why )    we think that the brightness from the light will become dimmer ,because there is more electricity being used by two light bulbs.

Materials:                                                                                                           (what you will need )

  • 3 light bulbs 
  • 3 circuits
  • 3 batteries 

Method:(write in steps.Include variables -what will you change?what will you keep the same ?what will you measure ?)

Step 1 : Set up circuit 1 and 2                                                                            Step 2 : Turn on circuit 1                                                                                        Step 3 : Turn on circuit 2                                                                                           step  4 : Observe the brightness of the two different lights

Observations:( what happened-include diagram)

The brightness from the light will become dimmer, cause there is more electricity being used by two light bulbs.

Discussion:
Our group feel that to help with our aim we should have done some research about what type of circuit to create. We think that what circuit we did create effected the end result of the experiment. Afterwards, we did some research on series and parallel circuits to decide that should have done one of those. They look like this:
A circuit od series and parrallel

There are different types of circuits; two circuits that we focused are called series and parallel”. Components that are connected in series are connected along a single path, so the same current flows through all of the components. Components connected in parallel are connected so the same voltage is applied to each component. In other words, If a wire joins the battery to one bulb, to the next bulb, to the next bulb, to the next bulb, then back to the battery, in one continuous loop, the bulbs are said to be in series. If each bulb is wired to the battery in a separate loop, the bulbs are said to be in parallel.

We think that after researching about this we should have maybe done something like the parallel circuit.

Conclusion:
Our experiment was successful because what we thought would happen did happen. The light bulbs on the larger circuit were dimmer than the light bulbs on the normal circuit. This happened because the electricity running through the larger circuit was being used up faster by the light bulbs than the smaller circuit because there is  more wire to get through and more light bulbs to power. Our circuit was a series circuit and our group feel that that effected the result of the experiment and should have set up a parallel circuit to compare them.

 

S.E.P.E.P Reflection

This year we had a fun activity called “S.E.P.E.P”.It stand for soccer education physical education program.In this activity we have to play soccer .We had been alegated into our teams ,My team was “The Green ninja turtles”.

All the groups had one colour ,that all the team members wore as a,shirt, bandana ,or anything that has to do with their colour.We also had our own jobs to do with in the group.We had  little training were captain and/or were in charge of that .We also had duty group ,that  was when a few groups were in charge of setting up for the games ,and during those games people also had jobs .E.g. scorer , first aid ,timekeeper and empire. Overall I’ve enjoyed playing S.E.P.E.P this year and hope all the 5/6’s next year do to.

100WC #week10

Another cloudy day, were everyone is so sad. But somewhere, somehow, there is I tiny bit of joy left. Tiny light of joy that is so powerful .I tiny bit that can wipe out a nation. How could something so tiny be so big. Who holds this bit of joy? a little girl on the other side of the world. She is the only one that believes ,who hopes and loves. If everyone has this joy ,we would be a much better ,world. We should follow in the footsteps of this girl. Remember something tiny has something big with in it.

100WC #week8

It was friday the thirteenth  ,coincidently halloween.I am very hard to scare ,you see.And all my friends have a competition to see who can scare me  the most  . Georgia went first ,she told  “a scary story”,then held a knife out at me at the end,I yawned .She sat down ,disappointed. next was lisa,but then a guy in a chainsaw walked in ,I think he thought it was scary .He said “follow me “in a deep voice .So I did ,my friends looked scared ,but I knew that this was just some other prank .He had brought to a grave yard and yelled ,”spirits of the night show us all your might ,you don’t me but I know you ,bad things I will have to do,I have a past so sad ,but that’s the thing that made me bad.”
