I think that the ecology unit sparked my interest the most because of the food chain and learning about the impact of removing one biotic or abiotic factor from the chain. From the heat transfer unit, I found it very interesting to learn about the different types of heat transfer and what it was. I found both of these units interesting because of my previous curiosity about it. Earlier I wasn’t given much chance to learn about these subjects, so I was glad to do get the opportunity to learn about them. I don’t have many other questions related to these topics.
