First we got a beaker and filled it with 200ml of water. Then we put in 1 Alka-Seltzer into it. Next we added 10 raisins and it started to fizz. The raisins sunk to the bottom and bubbles were attracted to the raisins. After that the gas bubbles lifted the raisins to the top of the beaker and then the gas evaporated into the atmosphere and the raisins fell to the bottom.

This week in numeracy we have been learning about volume. We investigated scales on different measuring jugs, we looked at the different units of measurement, we calculated the volumes shown by markings that didn’t have numbers and we read volumes using the scales.
We are now learning to convert l to ml. We do this by multiplying by 1000. It can be quite tricky when there are decimals involved. To mulitply by 1000 you move everything 3 places to the left, the decimal point stays still, so 0.025l would be 25ml.
This week is Math’s Week! We applied our numeracy and scientific skills when learning about light and shade. We went to the playground throughout Wednesday and drew a line to show the length and position of our shadows. We then measured the lines and the angles between each one. We sketched the movement of our shadows in class, again using a protractor to measure the angles. We then debated the reasons our shadows change in this way through the day.
Over the last two weeks we have been looking at the All About Me topic in a different way. We decided to learn about ourselves and each other in maths. We measured our height, our stride, our head circumference and our arm span. When Mrs Horne said we were going to put our results into graphs Shravan asked if we could do a graph looking at height and age. We made a scatter plot to see if there was a trend. We thought height might increase with age but there was no link between the two. We also mader a graph using excel.
In art we looked in more detail at our shoes creating line drawings with pencils. We used shading to show the shape of the shoe and if it was darker in some bits.
I enjoyed P.E. outside this week. I learned about dribbling and demonstrated the skills we were learning. I also enjoyed science. We have been making electric circuits and will be looking more into how they work soon!
I enjoyed writing. It was part of All About Me. I wrote about my personality and my strongest subjects and the ones I need more help in.
