K-5 science — common questions
What science does this site cover?
Kindergarten through Grade 5, across physical science, life science, Earth and space science, and engineering design. That is 158 printable worksheets and 90 lesson plans, every one tied to a specific NGSS performance expectation rather than to a topic name.
How many NGSS science performance expectations are covered?
78 — the full K-5 set for science. Each one is listed on the standards page with the published wording, a plain-language restatement, the worksheets that practice it and the lesson plan written for it.
Are the science worksheets and lesson plans free?
Yes, all 248 of them. There is no account, no email capture before a download and no printable that turns out to need a subscription at the last step. Print and photocopy them for your own class.
What is the difference between a lesson plan and a worksheet here?
A lesson plan is how to teach the standard: timed sections, the exact wording to use where the wording carries the evidence, the misconceptions to expect, and an exit ticket. A worksheet is the practice that follows it, with an answer key and 25 versions.
Which grades have science material?
All 6: Kindergarten through Grade 5, ages 5 to 11. Each grade has its own hub listing that grade's sheets grouped by the NGSS disciplines and performance expectations they practice, so a sheet can be found by code as well as by topic.
Can I print a different science worksheet for every student?
Yes. Every sheet is published in 25 versions, one per student, and set 1 offers all 25 as a single PDF — one download, 25 different papers plus their answer keys, ready for the photocopier.
