Summary
Uses the entertaining premise that we might be drinking recycled dinosaur water to explore the water cycle at a deeper level — focusing on long-term water storage in ice caps and groundwater and how slowly some water moves through the cycle.

Discussion questions
Discussion
- Why might some water molecules have been 'stuck' inside a glacier for thousands of years?
- What is groundwater, and how long can it stay underground?
- Does all water move through the cycle in days? What slows it down?
- What does this tell us about why protecting glaciers and aquifers matters?
Quick work-a-long
Vocabulary: water cycle, glacier, groundwater, aquifer, reservoir, deep storage.
Try it: Research how long water takes to pass through each reservoir: ocean (thousands of years), glacier (up to 100,000 years), river (days), atmosphere (about 9 days). Arrange them from fastest to slowest and discuss: which is most critical to protect?
