We reviewed last week's lessons, seeing as Jared was absent two days, and I could see he was not feeling well on Tuesday. He remembered a lot, despite everything! It was a very good lesson - once I saw Jared was remembering the lessons, I started to quiz him, as I used to do, and he did great. Then we started on the concept of the search for 'life' in the Universe, always stressing that it need not be like life here on Earth. We discussed the challenges for planets to host life, such as the extent of the 'habitable zone' and the presence of an atmosphere and a magnetic field, both of which shield the planet (as in our Earth) from harmful radiation from space. Jared was very attentive throughout the class, and again asked many interesting questions. It's good to have Jared back!
