Year 3 have been using their measuring skills to make an Egyptian Shaduf. A shaduf is a device that farmers use to get water from the River Nile to irrigate their farmland. The bucket is dipped into the river, and the weight at the other end of the “see saw” makes it easy to lift the water at the opposite end.
Year 3 had to measure in cm to create a shaduf of a certain height before using some larger materials to make a bigger shaduf outside in teams. What do you think?
Recently E3 have investigated measuring lengths using cm, mm and meters. There were several hidden measurements in the room and the it was a race to who could find them all first!
In Maths we found out that Mr O was very fussy when it came to drinking. He would only drink water that was less than 12 degrees celsius so we had to measure the temperature of our school water. Luckily it was 10 degrees celsius so Mr O was able to drink it.
Then we found out that he would only drink tea that was 50 degrees celsius so we had to add hot water to our containers until it was the correct temperature.
Finally, Mr O said it was too hot as he wanted it to be just 30 degrees celsius. As a result we had to add cold water to bring the temperature back down to 30.
What a fuss pot! E2
As well as measuring temperature in celsius we also learned that we measure it in fahrenheit. To convert a temperature from celsius to fahrenheit we double it (X2) and add 30 (+30).
e.g. 42C would be about 114F because 42 X 2 = 84, 84 + 30 = 114
This morning we awoke to a really cold frost and used this to help us with our measuring skills in Maths. We learnt that we use a thermometer to record the temperature in degrees celcius and it is important that we know how warm or cold it is so that we wear the correct clothes.
We practiced reading the temperature on different thermometers and said that it is just like a number-line that goes up instead of across and looked at the numbers below 0 that we call negative numbers. We measure the temperature inside our class which was 20C and outside which was -3C and found that the difference between the two was a huge 23C!

This week in E3 we have been looking at measuring and recording data.
Mysteriously, Mr Martin’s Ipad disappeared! There were 4 potential suspects in custody and E3 had to race against the clock to try and convict one of them. The only clues they had were several hand prints and footprints left in the room. They knew the suspects height and forearm measurements and they also knew that a persons height is roughly 9 x the length of their hand. They also knew that a person’s forearm is the same as there foot length.
The students/detectives in E3 needed to match the hand and footprints to the forearm and height measurements of the suspects. Both pieces of evidence were required to convict a suspect.
Ellamae, Jack and Joshua’s team managed to solve the crime first. They showed the class how they knew which suspect was guilty and how they worked it out.
