It's full of stars/teaching approach
Astronomy(topic) has been practiced for centuries and doesn't require expensive equipment! This first session aims to train the whole class(ta) to use a telescope and, hopefully, to provide an opportunity to engage in some active learning(ta). The lesson includes some naked-eye observations and describes how modern technology helps scientists know where to look. You can explore the scientific method(ta) and language(ta) at this point, using targeted questioning(ta)/differentiation(ta). Students may be able to engage in an inquiry(ta)-based project around this work, perhaps for homework(ta).
