We co-read an expository text from his language arts textbook, "When Is a Planet Not a Planet?" We paused to discuss the text and evaluate the photographs and diagrams. I remarked that NASA is launching a new telescope, the James Webb telescope, that will replace the Hubble telescope and greatly increase our knowledge of space. Mercer was interested, so we researched the topic and watched a short video on YouTube. We learned that the Webb telescope is about the size of an eighteen wheel truck, and will be launched 940,000 miles into space. The launch date is December 18, 2021.
