How do plugs work?
We had great fun being electricians this week!
We took wired plugs and unscrewed the plug case to reveal what was inside. We learned all about the function of the three wires and why every plug has a fuse. We reflected on previous lessons and discussed the material used for the plug case and flexible cable and related to whether they are conductors or insulators. We were all really pleased that the cable and plug had a plastic covering as we know that this is an insulator and protects us from the electric current.
We've had great fun over the last couple of weeks completing our companion projects.
What conducts electricity?
To begin this project, we experiemented with circuit components in groups to try and make complete circuits to make a bulb light up. We also included a motor and a switch.
We then thought of objects and materials that we would like to test in the circuit to see if they let electricity flow through them. We know that these materials are conductors and have low resistance and those that do not allow electricity to flow through are insulators and have high resistance.
We made a prediction for each material and then tested it out. We were very excited when we included the lockers as part of our circuit and the bulb lit up!
We came to conclusion that the metals we tested were conductors and had low resistance.
Can you make a circuit from dough?
Using the knowledge that we had already gained on circuits, we moved onto our next companion project.
We used two different recipes. When we used the one that contained lemon juice and salt to make a circuit, the electricity passed through and we concluded that these ingredients must be conductors. The dough with sugar did not conduct, it just made a sticky mess!
Reading Comprehension and RE
Over the past few weeks, we have been working on a number of reading comprehension strands including Define, Predict, Infer and Summarise.
We made our own murti of Ganesh.
We have had a busy week this week in Science!
We had great fun testing our hearing. We played music at a low decibel up to music at a high decibel. Each time we played a quiet or loud sound, we measured how many steps we could get away from the sound source until we could no longer hear it.
We concluded that the louder the sound, the further away we were able to hear it.
We also carried out experiments to explore pitch. Using elastic bands, we found out that the longer and thicker the band, the lower the pitch and the thinner and shorter the band, the higher the pitch.
This week, we have been labelling different parts of the ear and matching their function.
This week, we have been working together in small groups to create our own version of the poem ‘The Sound Collector’. We shared our ideas about the sounds we could hear around school and put our individual ideas together to create a group poem, which we then read aloud together. We had to think about our intonation and expression and as a challenge, we were asked to think of ways we could incorporate some of the sounds we were describing into the poem!
This term, we will be learning all about the celebration of Ganesh Chaturthi. This is when people who believe in the Hindu faith celebrate the birthday of the elephant god, Ganesh.
During a reading comprehension activity, we used images from the Hindu story of Ganesh and used our prediction skills to think about what we thought would happen in the text and describe the different characters. We then read the story and reflected on our answers to see if we would change any of them.
We then had great fun creating Ganesh masks and we became a class full of elephant gods!
We carried out lots of experiments this week to understand how sound is made.
We recorded our observations using labelled diagrams and written explanations.
We found it fascinating when the rice bounced on the cling film when we made a loud bang nearby and it was great that we understood how and why this happened.
By the end of the lesson, we came to the conclusion that sound is made when an object vibrates and these vibrations are sent through the air in sound waves to the ear. We had fun pretending to be vibrating air particles ourselves to show how this would work.
Having learned different music vocabulary earlier in the week, we listened to some live jazz music and talked about the pitch, rhythm, tempo and volume of the different sounds we could hear. We then thought about different shapes that we could associate with those sounds, explaining why we chose them. Looking at Kandinsky’s artwork for inspiration, we created our own abstract pieces by sketching ideas first and then putting these separate ideas together into a final, colourful piece.
More photos of the final pieces to follow!
What a brilliant start to the new school year!
We had a fantastic time during our memorable experience, listening to live guitar music played by Mr Booth. We rocked the morning away and some of us even created our own rock bands.
During a Speaking and Listening activity, we thought about the sounds we had heard within the live music and how also thought about how the music made us feel.
Within our descriptions we found some great examples of onomatopoeia.
In Science, we began looking at the volume of different sounds. Using sound meters, we listened to sounds we could hear around the school and recorded he volume in decibels. We also had great fun making loud sounds with the musical instruments!
