Ocean currents are patterns of waves that spread across the world. There are two main types of ocean currents, surface currents and deep ocean currents. Surface currents are currents that are the sea level or at the surface of the sea. Surface currents control around 10% of the world’s water. On the other hand, the deep ocean currents and currents that are below the surface and they make up around 90% of the water. Currents are primarily controlled by the wind, which mostly affects the surface currents. As the wind pushes the surface currents, the deep ocean currents are pulled alongside it with water around 400 meters below the surface still being affected by the wind. The reason that ocean currents are important is because they help to spread heat from sunlight across the globe. The two types of ocean currents make up something called the Global Conveyor Belt, which loops across the world, which is considered the longest current in the world. Originally, the Conveyor Belt moved a few centimeters a second, however due to climate change and global warming, the Conveyor Belt is believed to have slowed down. Due to this change, there have been issues with climates and weather systems. As such, it is vital that we study the ocean currents more to be able to better understand them, and to also work to reduce the impacts of global warming.

From my understanding, ocean currents are formed by wind patterns and the rotation of the Earth. The combination of the two influences the movement of air and, thus, the movement of the water. This is because the water at the surface of various water bodies is moved and displaced by the wind. As a result of the surface-level movement, the water below also gets displaced to some extent, creating ocean currents.

These are very important as they influence factors like regional climate and temperature, and, if they were to change, species adapted to the biotic factors of the region would struggle as they are thrust into different environments in terms of temperature, salinity, pH, etc. This may put numerous species in danger of extinction as they struggle to survive their new environments, disrupting the ecosystems and the food chains they belong to.

Watching the video helped me understand the vital role ocean currents play in shaping our world. I was fascinated by how a simple accident such as 28,000 rubber ducks being lost at sea led to a better understanding of how ocean currents work. I learned that currents are influenced by wind, tides, water density, and even Earth's rotation, forming complex patterns like gyres. Surface currents regulate heat distribution, while deep ocean currents, driven by temperature and salinity, form the Global Conveyor Belt, which sustains marine ecosystems. It surprised me that a single water droplet could take a thousand years to travel through this system, However, the mention of climate change slowing these currents made me concerned about the consequences for global weather patterns. This video showed me that ocean currents are not just water movements they are a lifeline for marine life and climate stability, making their study essential for our future.

From this activity, even though I already knew quite a bit about ocean currents, altitude, latitude, temperature and precipitation, I learnt lots more about them. As we began making connections between each and the new concepts like microclimates, I gained a better understanding of each of the concepts and their influence on climate.

In today's lesson I got a better understanding of the levels of biodiversity, especially the interconnectedness of the three in maintaining an ecosystem's biodiversity and resilience. We also covered conservation of biodiversity and it brought to light the importance of collaboration to be able to protect an ecosystem's biodiversity.

From this lesson, I learnt about the types of biodiversity, species diversity, habitat diversity and genetic diversity. I also learnt about resilience in ecosystems, and I learnt about ways that people can help to conserve biodiversity.

The activity that was conducted yesterday was good but if wee had got little more time like of 10 to 15 min we could have done better and as most of the student had went for there art work so it was not more interactive I hope in future we may get more such activity.

Please write exit tickets on the lines of:

1. What did you learn from the class?

2. Which section did you find difficult?

3. What did not go well in the class?

The activities that we performed in the class on how environmental value systems affected us . And from the activitie we learned how it affects us but there were some difficulty’s that we faced like stage fear . The thing that did not go as planned was that we could not present it well but we learned many attributes thank you
