Learning in Year 4

TV Adverts
After writing our own TV adverts in literacy, we performed them in small groups to the class. We then used our new Plickers cards to evaluate our friends’ performances. The iPad scans the Plickers cards and shows a graph of the results. We can also use them to answer multiple choice questions the teacher has written for us.




Science – Egg Drop!
After learning about the history and science of parachutes, we designed a container for an egg and a parachute to help it float gently to the floor. We then dropped them from the Year 6 stairs. Almost all the eggs survived, though some did crack. Surprisingly, having a large padded container didn’t seem to be the best solution – the small light containers worked better, with the parachute really slowing the fall of the egg.




Chocolate bar fractions
We imagined a party game where one chair had one chocolate bar and another chair had two chocolate bars. The guests had to stand by one of the chairs, then share out the chocolate on the chair between all the children at that chair. After we tried a few examples together, Hayden thought about what would be the best for 12 guests to do. At first he thought it might be 6 children at each chair, but then the children at the first chair would only get a sixth of a bar each. In the end he worked out it would be best for 4 to go to the first chair and 8 to go to the second chair, then every child would get a quarter of a bar.



Strong triangles
In science, we looked at photographs of tents, bridges and other structures and noticed that triangles were often used in order to make them strong. We then made our own bridges out of straws and masking tape, before testing their strength with dictionaries!




Science and History in 4.1
As part of our study of inventions from the Islamic Golden Age a thousand years ago, we tried to turn our classroom into a camera obscura. We blocked all the windows apart from a small hole in a piece of cardboard. We then held a white piece of paper as a screen for the light to fall on. You can see a blurry picture of the view outside. The image is upside down, just like happens in a camera or in your eye - the bright sky is at the bottom, and you can see the shapes of the trees and the mobile classroom roof. If you look carefully you will see a yellow rectangle in the middle. This is a piece of coloured paper being held by a child outside. When the yellow paper was waved around outside, we could see it moving on the white paper screen inside.



Roman Shields
Near the end of our Roman Britain topic, Year 4 made some Roman shields from stiff cardboard and painted them in bright colours. These photos show 4.1 displaying their shields in the large hall and then using them in various Roman army attack and defence formations. The adults really enjoyed the activity too!


In Maths, 4.1 looked at an old Maths Trail created by a teacher at Queen Edith before we were born! We decided to create our own updated Maths Trail. In small groups, we walked on a circular route around the playground and corridor, planning maths questions to ask at each place on the trail. The questions involved measuring distances, timing with a stopwatch, counting, and finding the temperature with a thermometer. The next week, we tried out our Maths Trails. We particularly enjoyed using the new school trundle wheels! 

 Burglar Alarms
In 4.1, we combined Science and Design Technology to plan and make a burglar alarm to protect a model of the classroom. We started by remembering how to make circuits so that electricity could flow round them. We then made our own “pressure pad” and “on-off” switches. Finally we created the model of the classroom and installed a burglar alarm. We tried to make our circuits stable so we didn’t need to keep repairing them; we also made them reliable so they went off when the burglar entered, but didn’t go off during the day when children were in the classroom; if we could, we tried to hide the alarm so the burglar wouldn’t spot it.


Maths Fractions
We spent some time in 4.1 looking at how tenths could be represented as both fractions and decimals. We cut out some fraction dominoes and put them together so that each fraction matched its equivalent decimal.


Andy Goldsworthy Part 2
After enjoying making our previous sculptures using leaves, we tried a different natural material: sticks! Which one do you think was the hardest to get just as we wanted it?

Year 4 Maths – Symmetry
In 4.1 we have been learning about lines of symmetry. In groups of four, we used a loop of string to make different quadrilaterals. We tried to make them with one, two, three or four lines of symmetry. Here are three shapes with one line of symmetry. Can you remember their names?

Year 4 Art
We have gathered natural materials from the field and playground to make our sculptures inspired by Andy Goldsworthy. They are temporary sculptures, just like his; we have photographed them and left them to be scattered by the wind.
