Investigating melting points
After learning about changes of state, our children have been independently researching the melting points of different metals. They presented their research using both a table and a bar chart. Of the metals that they researched, they found out that iron had the highest melting point and mercury had the lowest melting point.
Mercury would be a liquid at room temperature as it melts and becomes a liquid at -37oC!
Grouping Living Things
Year 4 have been working scientifically to group living things using Carroll and Venn diagrams. They worked independently on google classrooms to create their diagrams and sort the living things in different ways using different headings!
Conductors and Insulators
After learning how to create simple circuits, the children have been planning their own investigations to test which materials are conductors of electricity and which are insulators. They made their own predictions and spotted the pattern that the metals were the best conductors as the bulb lit up in their circuits when metal materials were used.
'I didn't realise that foil was a metal - but the bulb lit up so I researched it and found out that it is made of a metal called aluminium!'
Creating and testing circuits
Our pupils have been using their knowledge of how to create a complete circuit to independently create circuits, making secure connections. The children independently used their understanding to predict and test each circuit, as well as creating examples of their own using their circuit knowledge.
'I knew that the bulb would not light up because the wires have to be connected to each end of the cell so that the electricity can flow around the circuit. When I created the circuit to test my theory I found that I was correct!'
Independently researching invertebrates
After learning about the main invertebrate groups, the children have been using their scientific research skills to find out some interesting facts about different invertebrates as well comparing them to vertebrates.
'Did you know that the biggest earthworm ever found was 22 feet long!'
'I always thought that spider were insects but they are actually arachnids!'
