the maze had wires connected to a the plain tin foil then to a light bulb. The point of the maze was the light bulb was the light bulb was connected to the tin foil was permanently on and when you go off the path the light would go off. We had lots of dificulty’s making the experiment but we kept on persisting and in the end it didn’t work. At the end of the day Mrs Naismith tried to get it working and it worked!!
On 22nd of May we had our Open Night here at Berwick Lodge Primary School as we we’re getting ready to show our families and friends our work that we have done and completed since term 1 but the main thing that our class wanted to show off was science.We each got put into different groups and the people in my group were Suvi, Jake and I. Jake was away but Suvi and I still did our book about electricity. Suvi’s part was explaining why humans use electricity and my part was what is electricity. After all that we designed our book for Open Night but even though I didn’t go I herd it was fun
During this term we have been learning about electricity. Lockie and I have been studying about series and parallel circuits. A series circuit has only one path and the parallel circuit has more than one path to the electrical appliance.
If the series circuit is opened the electricity won’t be able to pass through.Electrical insulators are materials that have a high resisitance to electricity and won’t allow it to flow through them just like a series circuit.
If your hands are wet never plug in a electrical appliance.Your body is about 55% to 65% of water. Human bodies are very good conductors.If your hands are wet and you plug in an electrical appliance you could possibly die or get electrocuted.The strenghth of electricity that is given to our home is low compared to the voltage in the power lines. It is at 220-240v but is still very deadly.
Lockie and I set up a series circuit and a parallel circuit for open night. For an experiment for the series circuit we made a light bulb turn on and for the parallel circuit we made a fan work. Lockie and I loved learning about series and parallel circuits.
The grade 6’s in 5/6N were studying electricity, while the grade 5’s were studying light. For our science experiment, Mrs Naismith moved us into groups. In mine there were, Hayden, Nathan and myself. Our group could choose any type of electricity for our experiment. Hayden and I looked for an experiment to make. We decided to make a maze with these pieces of equipment:
2 sheets of foil
1 square piece of coloured paper (on our maze we used orange)
1 piece of cardboard (the same size as the paper. You can always slice it up)
3 lines of wire
1 light bulb
1 piece of contact
1 stanley knife
We made the foil the path of the maze, while the coloured paper made the whole maze stand out. Here is the information I typed up in my own words:
Insulators and Conductors
Our body is a conductor, especially when we are wet. That is why we never touch electrical appliances while wet. A conductor allows electricity to pass through. We use conductors to move electricity from one place to another. We use insulators to stop electricity reaching dangerous places. Electricians wear rubber boots to prevent getting electric shocks from wires. Metal wires conducting electricity are insulated with either rubber or plastic to make it safe from electric shocks.
Why it Works
The aluminium foil conducts electricity, and makes the maze able to be completed. The bulb glows , only while the nail is not touching the plastic inside. The reason is because plastic is an insulator. A conductor must contain charged particles that can move around. These electrons pass on the current. These electrons in plastic cannot move around. Therefore plastic is not a conductor.
In the last few days we have been making science experiments for Open Night. I was in a group with Erin and we both had lots of fun together doing this experiment I am about to tell you about. First of all we attached a pen to a ruler and we also made all of these signs about the science experiment to explain how it worked.When you hit the ruler and it vibrated the pen drew a sound wave on the piece of paper. But what is vibration? Vibration is when an object moves up and down or side to side. You might have a alarm that is set to vibration on your phone or when you set your phone to silence it might vibrate. If you still don’t know what vibration it is when a object shakes.
A few days ago, everyone had to get into a group of 2 or 3 and pick a science topic for open night. Rahni, Gemma and I were all in a group. Our topic for refraction. This is some information about what refraction is. We can see the refraction happening if we put a pencil in a glass of water .The pencil appears to have an unusual shape as the light rays have “bent”. Light can be refracted through an object. Rahni, Gemma and I are doing the pencil in the glass of water for open night. So Rahni. Gemma and I went to get a glass of water and a pencil. Mrs Webber got us a jug of flowers in it and it was refracted, so we used that too.
Grade 6s are learning about what electricity is in Science. Some of the experiments we have done include using a lemon as a battery and making our own electrical circuits. Here is more information about a series circiut. Series is an electrical circuit that only flows though one path. A parallel circuit is a circuit that can go though more than one path. Ish and I made circuits for Open Night to show the visitors the difference between the circuits. Here we are with our two different circuits.
What is opaque? Opaque is where you can’t see anything thourgh it. For open night , Nihaal and I did an experiment. The experiment was, ‘ An opaque’. For the experiment, we made a card game. We used coloured paper and a torch.We put the torch down on the table and the paper and we didn’t see the light thourgh the paper. If you can’t see an object it’s opaque.
This term, 5/6 N’s topic was science. The grade 5’s topic was light and the grade 6’s topic was electricity. We had to get into groups of either 2 – 3 people in one group. In my group was Amy, Gemma and I and our experiment was about refraction. Our experiment was, we had to get a glass and fill a third ( 1/3) of the glass with water and another third (2/3) of the glass as well but this third with oil. Then we also got a pencil and put it in our glass and when you look at it, it looks like the pencil is broken.
What I am learning in science is:
The type of the electricity I have been focusing on with my group (Meryn, Kiah and I) is Conductors and insulators.
Now for those who are visiting our blog and would like to know what conductors and insulators are, I will explain it for you:
A conductor allows electricity to flow/pass through a circuit without interuptions and some things that are conductors are – The human body because water is a good conductor and the human body is 55% – 65% water, metal, Copper, Zinc and more.
An insulator is usually made up of plastic and covers cords so that electricity can not escape from the cords or pass through, so there for you don’t waste power.
So that is what I have learnt and hopefully you have learnt some thing from my writing to, also we will be doing more science experiments.
Below is a photo of me and Kiah with our work, Meryn could not be in this photo becuase she has no picture publicity for the interent.
