3-LS1-1, under Life Science for Grade 3. The published performance expectation reads: “Develop models to describe that organisms have unique and diverse life cycles but all have in common birth, growth, reproduction, and death.” The worksheet assesses that performance expectation rather than a paraphrase of it.
Egg, Growth, Eggs Again is written for Grade 3, typically ages 8-9. It is one of the sheets on 3-LS1-1, so it suits any student working at that standard — including older students revisiting it and younger ones working ahead.

25 — one per student, and all 25 ask different questions. Set 1 downloads the whole class as a single PDF. Every version is fixed to its own address, so a sheet printed today holds the same problems when you reopen it next week.
