Grace,
interesting choice of book:
it seems to be about a lot of different usages of stars (as rewards, as calendar markers, as something to keep in your pocket), but finishes up with a bit of night sky.
Given that SESE Geography expects Infants to identify and discuss the sun, the moon and stars
I’d try to keep the discussion on similarities and differences.
Be careful with statements like: “They are much bigger and hotter than our sun” since some stars are bigger and hotter, but in the immediate region of space near the Sun, it is one of the biggest. Smaller and cooler stars are harder to see, so the stars we see in the night sky are preferentially the nearer and naturally brighter ones. This advanced level activity lists stars by proximity and brightness.
How long would you expect to take with this sequence of activities and would you arrange this as stations?
