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!
We have been looking at how the Earth was formed and the reasons why it has an iron core and a rocky outside. Here are some models that we made to help us remember the layers.
Today the pupils investigated the pattern between shadow size and the distance of their light from the object. They plotted x-y scatter graphs that showed this relationship, and had great fun!
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.
The pupils planned presentations about different animals, including finding out about how they reproduce. Their presentations were fantastic!
In science we have been looking at rockets and planes. The photos below show the hoop planes that the pupils built. Some of them flew all the way across the room!
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.
Here are our results from the experiment
Levi has made this post! Gears change the speed and the power of things. Today we all had a go on the bicycle on the turbo trainer. We worked out our average speeds, and felt what it was like in different gears.
Pupils were given the chance to dissect pigs’ eyeballs from the butcher. We were all fascinated by the lenses inside the eyes. When you put the lenses on some newspaper they magnified the writing.
