Questions about The Path Light Takes

What does the The Path Light Takes worksheet cover?

It practices modeling how reflected light entering the eye lets objects be seen — 2 questions for Grade 4, all on NGSS 4-PS4-2: Model how light bouncing off a thing and into your eye lets you see it. The instruction to students is “Number the steps from 1 to 4”, and the answer key follows on the next sheet.

Which NGSS performance expectation does The Path Light Takes practice?

4-PS4-2, under Physical Science for Grade 4. The published performance expectation reads: “Develop a model to describe that light reflecting from objects and entering the eye allows objects to be seen.” The worksheet assesses that performance expectation rather than a paraphrase of it.

What age or grade is this worksheet for?

The Path Light Takes is written for Grade 4, typically ages 9-10. It is one of the sheets on 4-PS4-2, so it suits any student working at that standard — including older students revisiting it and younger ones working ahead.

Does The Path Light Takes come with an answer key?

Yes. All 2 answers are generated from the same problems as the questions, so the key cannot drift out of step with the sheet. It starts on a fresh sheet of paper, after the questions, so it is not handed out with the class by accident.

How many different versions of The Path Light Takes can I print?

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.

Is The Path Light Takes free to print and photocopy?

Yes. The Path Light Takes, its answer key and its 25 versions are free to print and photocopy for your own class, with no account, no email capture and no subscription at the download step. Please do not resell them or republish them as your own.
