Marine science, intro and chapters

This blog is for my Marine science class at Ranum Efterskole College, but if anyone else can use it, they are more than welcome. All the content here is non profit, and all errors are mine and mine alone. I have taught AS and A level Marine sciene since 2014, and the new IGCSE sylabus for two years This blog will cover the Marine Science 0697 syllabus, and have small videos of my class and the stuff we do. Syllabus sections will appear here below as they are done: Practial skills : 0.3 seperation 0.4: cooling and Ice formation 1.2; Heat from the core Ocean currents 2.1: Melting ice and sea level Chapter 2: Diffusion 2.2. PH and indicators 2.3 Dissolved gasses 2.6: Effect of temperature on density 2.8: Visibility 2.3:Activity- Upwelling 4.1: Nutrients 4.2: Respiration 4.3: Photosynthesis 5.1 and 5.2 Extra experiments Density Ecosystem models Ecosystems Salt and salt crystals Tectonic plate models Heat and expansion Section 1: The Earth and it's ocean: 1.1 Structure of the ear...

IGCSE Marine exam 2 Oct/Nov 2024 -practical

Here we are looking at paper 2 from oct/Nov 2024 This is the one where you work a LOT more with data and experimental setups So, remember your ruler and your calculator And do please look at the experiments in the book. This one here rests heavily on Practical 5.1, 5.2 and 5.5. One question is basicly practical 5.5. There is a LOT of points you can get just for knowing how to calculate percentage, draw a table and a graph, and to draw a picture of a fish, so there are KEY skills to practice before this exam. Here is a small video for 5.2 and 5.2: And its also good to have looked at Biological drawings ( page 35 to 37 in the book)and plotting graphs ( Page 38 to 46 in the book) Question 1 and 2 Question 3 and 4 Question 5 and 6

IGCSE Marine science section 1.1 :Structure of the Earth

Welcome to section 1.1 in the syllbus, and chapter 1.1 in the IGCSE coursebook. Index can be found here The syllabus here decides the stuff we need to work on. 1: Describe the Earth as a planet orbiting the Sun, and the Moon as a natural satellite orbiting the Earth 2 State that gravity keeps the Earth in orbit around the Sun, and the Moon in orbit around the Earth 3 Describe the structure of the Earth 4 State that the iron core creates a magnetic field around the Earth You can find the keywords for the chapter here: So,the chapter covers the structure og out wonderful planet ,and it's location in the solar system. This might seem like a funny way to start marine Science, but the location, rotation and tilt of our planet have a huge impact on our marne systems. Just a bit closer to the sun, and most water vould be vapor. And just a bit further away, and most water would be ice. Earths tilt also explains our seasons, and seasonal variations in light intensty and temperature, ...
