Understanding

Comparing and contrasting coastlines

 

Our year 4 children discovered the different features of a coastline formed by the process of erosion. They then showed their understanding by comparing the formation of Formby’s sand dunes to Durdle Door’s arch! 

 

'Did you know that sand is made when rocks are broken down by waves? This is called erosion!' - Amelia

 

'An arch is formed when a cave is eroded by the waves, causing a hole to form in the headland!' - Charlie

Using and Making Maps Four-Figure Grid References

 

We developed our understanding of maps and four figure grid-references in order to read maps. We used a map of our local area to answer questions about four-figure grid references and the features within different squares. 

 

"Did you know that grid lines are numbered to help us to locate specific places on a map? The horizontal grid lines are know as ‘Eastings’ and the vertical grid lines are known as ‘Northings’."- Lucy ,C7

 

"To work out four-figure grid references, we first had to find the two-figure horizontal reference at the start of the grid square. Then, we had to find the two-figure vertical reference at the start of the square. Using the horizontal reference first, we put the two reference together to create a four-figure grid reference. This is the same way that we use co-ordinates in maths!"- Kaidyn, C8

Compass Directions

We used our understanding to identify and use the cardinal and inter-cardinal points on the compass. Then we created a compass panorama of what we could see using the cardinal points.

 

"Did you know that a compass has four cardinal points? They are North, East, South and West. Some people use a mnemonic to help them. I always say ‘naughty elephants squirt water’ as it makes me laugh!" - Ellie, C5

 

"Following on from Ellie’s point, a compass also has inter-cardinal points. They are North West, South West, North East and South East. We live in the North West!" - Bobby, C5

Mountains: How they are formed

 

In Year 3, we learnt all about Volcanic mountains. This year we have had the opportunity to develop our understanding further by exploring how volcanic mountains are formed. 

 

 

"Did you know that volcanic mountains are formed by hot magma being forced through weaknesses in the Earth’s crust, called volcanic vents?  As the magma bursts through the crust, lava, rock and are ash and thrown into the air. These materials fall to the ground, they form a pile, which, over time, grows into a cone-shaped mountain as the volcano continues to erupt." - Joseph, C6

 

"Did you know that most of the highest mountains in the UK are extinct volcanoes?" - Luke C7
