Goldfish in Fishbowl Under Bell Jar - Science & Classroom Illustration #1357043 (License: Personal Use)

This simplified educational illustration shows a vibrant green fishbowl containing a single goldfish, positioned directly beneath a transparent gray bell jar. The setup visually represents scientific concepts such as oxygen depletion, closed ecosystems, or experimental containment in classroom demonstrations. Clean lines and bold colors make it suitable for young learners and presentation slides.

Used in elementary and middle school science curricula to explain respiration, photosynthesis limitations, or lab safety; often appears in digital worksheets, interactive lessons, or teacher-led demonstrations about environmental control.
