I have 8 years of very comprehensive higher education in the field of Biology: from plant, animal, molecular/cellular biology to Parasitology and Genetics/Epigenetics. I have just finished a 4-month replacement in SVT for the 1st, 2nd and 12th grades and in Scientific Education for the 1st and 12th grades. In the SVT program there were Immunity, Genetics, Reproduction, Vector/Infectious Diseases, Microbiota, Cancer, (...). There was also geology. In the scientific teaching program there was for example the Radioactive Balance of the Earth/The Human Thermal Balance, Photosynthesis (1st) on the one hand. On the other hand, global warming and the evolution of human beings (terminal). If these themes are covered during your lessons, I can provide you with other explanations and exercises to contribute to your success!
