How Telescopes Work
CONCEPTUALKnow that telescopes are instruments that help us see distant objects in space, and that space telescopes like Hubble and James Webb orbit above Earth’s atmosphere to get clearer views of the universe
Mastery Evidence
- Explain that a telescope magnifies distant objects so we can see them in more detail
- State that Earth's atmosphere blurs the view, so space telescopes get clearer pictures
- Name at least one space telescope (Hubble or James Webb) and describe what it does
Assessment Prompt
“Does [child] know what a telescope does and why some telescopes are sent into space — like the Hubble or James Webb telescopes?”

- The Sun is a starsoftAges 7—9
Show full prerequisite tree
- The Sun is a star soft
Understanding the Sun as a star motivates learning about telescopes for studying other stars
- Why seasons change soft
Curriculum daylight/seasons observation supports exploratory Sun/Moon/stars identification
- Naming the Planets soft
Relating daylight length to time of year draws on orbit and solar system vocabulary
- Days, Weeks, Months & Years soft
Observing and describing seasonal changes requires basic date and time vocabulary (months, seasons, year)
- Ordering Events in Time hard
Understanding days/months/years builds on sequencing events chronologically
- Sun, Moon & Stars hard
Must know the Sun and stars before learning about planets and the solar system
