Use external classroom tools thoughtfully
CapeCodScience.com is a curated gateway, not the owner of the external resources we link to. Teachers should preview activities, confirm age appropriateness and accessibility, follow school or district privacy requirements, and review safety guidance before student use. For citizen-science platforms in particular, check each service’s educator and youth-account guidance first.
