Living Things and Their Habitats


 Plastic Pollution Presentations 

Year 4 have been learning all about the positive and negative effects that us humans have on the environment. They worked in pairs to research the harmful effects of plastic and discovered how humans can help reduce the impact of plastic pollution. Next, they created and presented presentations using their computing skills to showcase their knowledge. Finally, they presented to the class using their oracy skills. 

Sound: True or False?


After recapping their knowledge of materials from Year 2, our children have been thinking about which state of matter different materials belong to. They used their Oracy skills to give reasons for their responses.

History Focus: Sound


After learning about how sounds travel through vibrations, Year 4 have been developing their understanding of some key discoveries in the development of devices to support people with hearing problems. They then used their oracy and reasoning skills to explain each discovery and explain which discovery they thought was the most important and why.


Following on from Eva's point, I think that the most important discovery was the telephone because this was the first step in amplifying sounds using electricity!


Solids, liquids and gases

After learning about the properties of each state of matter, our children have been closely observing different materials to decide whether they are solids, liquids or gases. They then used their scientific oracy skills to explain their findings to the class and explain why they thought the material was a particular state of matter.


'I think that the ketchup is a liquid because even though it is thick you can still pour it and it takes the shape of the container - it just pours more slowly!'


How do we hear sounds?

Our children have been learning about how vibrations travel through the air and reach our ears. They have focused on their spoken language, using their scientific vocabulary to explain the stages in hearing sounds, from the vibrations reaching our ears and hitting the ear drum, to the message being sorted by the brain!


'When the vibrations reach our ear, they hit the ear drum, which then starts to vibrate.'


'The cochlea contains a liquid which moves around as our head moves and helps us to balance. That's why our ears are important for walking!'


'I worked really hard on changing my tone of voice so that I didn't sound like a robot when I was speaking!'


'I need to try an improve my volume next time I present'
