This lesson introduces ocean acidification, the other carbon problem. The ocean absorbs about 25% of human-produced carbon dioxide from the atmosphere. This helps to mitigate climate change but is not without its negative consequences for the ocean.
This is a practical lesson where students will develop their working scientifically skills and develop their literacy by writing a scientific conclusion using the ‘Point Evidence Explain’ technique from English.

This activity teaches students about the amount of carbon in the different stores, e.g. ocean, atmosphere, and fossil fuels. It is a group activity designed for between 4 and 6 students. Students will also learn about how carbon passes from one store to another.
This activity focuses on the processes in the global carbon cycle. It can be played individually or in small groups of two to four. Each player will move their counter around the board using the instructions. Players will use a dice to see how their carbon counter will move around the different stores in the carbon cycle.

This lesson reviews students’ knowledge about the carbon cycle within the context of the study of ecosystems for GSCE Science (Biology) and Geography, as well as the changing composition of the Earth’s atmosphere for GCSE Science (Chemistry). It covers the carbon cycle and major carbon stores and fluxes. The lesson combines a digital interactive carbon cycle diagram to reinforce knowledge of the processes in the carbon cycle, with a hands-on activity to introduce students to the size of the major carbon stores and fluxes. Exam style questions and a knowledge organiser provide a good revision focus.
Learning outcomes

In this introductory lesson, we look at the scientific processes and concepts of the carbon cycle. This will enable students to grow prior knowledge of food webs, respiration, and photosynthesis, as well as the combustion of fossil fuels into a more complete model. The lesson starts with an exercise to illustrate the range of different forms of carbon and carbon compounds and where they are found. This is followed by a gamified exploration of the carbon cycle. Key vocabulary and an understanding of the carbon cycle and its link to climate change is developed through a dominos task and short answer questions.
Learning outcomes
Identify where carbon can be found
Describe ten basic processes of the carbon cycle
Demonstrate their understanding of carbon stores and movement between them
Link increasing carbon in the atmosphere to climate change

Submarine STEM 11-14 provides middle school / lower secondary school science and design and technology teachers with an engaging resource to explore the science and engineering of submarine exploration. The 6 lessons of Submarine STEM 11-14 are based on the exploratory submersible journeys undertaken as part of the XL Catlin Deep Ocean Survey. The XL Catlin Deep Ocean Survey was the first Nekton Mission and the first multidisciplinary scientific research program to measure the health and resilience of the deep ocean off Bermuda, the Sargasso Sea (between Bermuda and Canada) and off Canada’s east coast.
Submarine STEM challenges students to consider different aspects of submarine design. Each lesson contains a standalone practical investigation examining the scientific principles involved in safely exploring the deep ocean. The deep ocean is extremely difficult to observe and until recently marine science was conducted entirely from the surface. Students will follow in the footsteps of pioneers in deep ocean exploration, considering the different scientific concepts from forces and pressure to material choices needed for surviving in this inhospitable yet amazing environment.
