ORIGINAL IDEAS. CLEAR SOURCES.

Sources & reuse

TeechTempo provides 100 linked lesson listings: 82 Census Bureau resources and 18 NASA/JPL resources. Our summaries, general teaching outlines, and subject illustrations are original editorial additions. Titles, grade ranges, durations, and material inventories identify the resources and help teachers prepare.

Full source lessons, worksheets, videos, images, answer keys, and provider procedures remain at their original locations. We have not obtained a blanket license to redistribute them, and linking does not give users one. Check each resource’s license, third-party credits, and permitted uses before copying, adapting, distributing, or using provider branding. Do not assume every government-hosted item is public domain. JPL’s image policy is not a blanket license for lesson text.

Subject illustrations are decorative TeechTempo artwork. They are not photographs of the actual activities and do not imply provider approval. Group sizes, normalized times, learning supports, and preparation advice are editorial suggestions, not certification or individualized recommendations.

Reviewed October 22, 2026. All 100 source pages were reviewed: 88 through direct page retrieval and 12 NASA/JPL pages through web retrieval after empty automated responses. Linked resources can change. A successful page check is not copyright clearance or a safety certification. Always open the full original guide.
