Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 2
- Stars come in many sizes. Some stars are smaller than the sun.
- Some stars are giants, much bigger than the sun. The biggest stars are supergiants. They can be hundreds of times wider than the sun!
- So the sun is a medium-sized star. But it's still huge compared to Earth: about 100 Earths could fit in a line across it!
- Scientists compare sizes with words like bigger, smaller, biggest, and smallest.
- Your turn! Put these in order, from the smallest to the biggest.
Georgia Standards of Excellence in Science:
- S2E1.a — Ask questions to describe the physical attributes (size and brightness) of stars.
