Thank you so much for all the great memories Class 4. I have loved teaching you Science over the last few years. I look forward to hearing about all of your future achievements! Thank you for all the lovely cards, the memory book and presents. Mr Phillips.
We looked at how different musical instruments make sounds. We also looked at how sound is a vibration and how the vibration travels into your ear and how your brain receives the information about that vibration.
In the second lesson we investigated which ,materials were the best for making ear protectors. Three of the boys invented stick on your ear, static ear protectors!
Chromatography works like this: when some ink gets wet, the ink colours get wet and flow to the top. The heaviest colours are dropped off first then the ink’s lighter colours get dropped off until there are no colours left.
In science we have been learning about Forces. This week we were dropping paper cake cases from a certain height, and adding one on each time. My group dropped them from 1.4m and timed them to see how long they took to get to the ground. We found out that our prediction was entirely correct (that when you add a cake case, it will fall quicker because there will be the same amount of air resistance but the mass has increased) but we also found out that the speed is increasing but it can kind of only reach a certain speed.
