River Study at Horton Kirby

On Wednesday April 20th Year 4 went to Horton  Kirby to study about rivers. We studied the flow and the depth of the river Darent.











The ducks have been released!!!



In order to do so, we had used rubber duckies and calculated how long it takes to travel 10 meters on the river. Since a river has 3 different parts, we collected our data on the three sections of the river Darent (A, B, C)


This is a small example of how much water there
was in our boots.... 

Jasmine is looking at the ducks to make sure
she stops the time when it reaches 10 meters. 
Once we were all wet, some of us had short wellies and the river was quite high, we walked back to the education center and learned about aquifer and the journey of the river Darent. Most of us were surprise to learn that it stops in Dartford and that where the city got its name from. 

Kathryn and Holly are experimenting which rocks are aquifer.
Year 4 students were lucky to visit Horton Kirby and put into practice what they had learn during the topic lessons. Mr. Berry, our instructor, kept repeating how amazing we were and how much we already knew.

We did learn a lot of things, we learned that there was chalk in the river and that was an aquifer, meaning it absorbs water.

 "It was a very fun school trip. The experiments were interesting to do. I got soaked!"                                                                  - Millie
 "We were in a room, it was like an olden days room. We looked at rocks with a microscopes, the rock that absorbed the most water was chalk. We tested the flow of the river Darent, I got water in my wellies. I learned that the deeper the river the fastest it goes"                                       - Isabella

River pollution!!

In year 4 Venus we have been learning about the effect of river pollution.It was very fun.
We also learned that if you find pollution at the start of a river it can travel extremely quickly to different parts of the rivers.
During this lesson, we did a science experiment on how pollution can travel to each part of a river quickly.
We did the experiment by getting three cups of water and then getting plastic tubes full of water linking the cups together. Afterwards, we needed a jug for the source and then food colouring to represent pollution. 

Miss Goulet slowly poured it into the source (jug).Next we poured the source into the first part of the river (first cup) we watched the fist cup pollute the others.

We learned that a small amount of pollution will be spread to many parts of the river and even in the sea. 

Once all the cups were polluted, we tried to clean the water. We did not manage to completely clean the water. There were still food colouring in the cups.
