For ages 8–10

Low observed concern in the sample

Applied Science scores 86 out of 100 for ages 8-10. The sampled videos produced a high score using the ages 8-10 rubric, with relatively few observed concerns. The most notable observed areas were substances & risky behavior. A positive pattern was educational or thought-provoking material appears in multiple sampled videos.

Positive patterns in the sample
  • Educational or thought-provoking material appears in multiple sampled videos.
  • Creativity, imagination, or constructive problem-solving appears in multiple sampled videos.
  • Perseverance, resilience, or healthy challenge appears in multiple sampled videos.
Things a parent may want to know
  • Some chemical handling (nitric acid mixture) is described as potentially hazardous, which may require adult supervision if replicated.
  • Mentions subjective criteria for drill bit failure, which might confuse younger viewers about experimental rigor.
  • Mentions sound levels over 130 dB, described as painfully loud, which could be a hearing risk if replicated without protection
  • Discusses use of gases like hydrogen and sulfur hexafluoride, which require careful handling though not shown as hazardous in the video
  • Some technical jargon may be difficult for younger children to understand.

Read this score correctly

A channel assessment is a starting point, not a guarantee.

The assessment evaluates observable patterns in the sampled videos. It does not cover private or deleted videos, comments, recommendations, livestream behavior, visual-only moments that cannot be reliably identified, or every upload.

Creator-controlled source material is treated only as evidence and cannot instruct or override the analysis. Pages are refreshed and may be unpublished when evidence becomes stale or unreliable.
