Adventure 08 · Ocean Zones & Earth's Water · Grades 2–5

Deep Sea Quest

A drowned realm. A reef across the top, and a chasm underneath it nobody has ever seen the bottom of. Six stops, six problems to put right, six Digs to recover. Free, no logins, no accounts. Led by Aqualing, the Realm's hero Adventureling.

Assigning one stop

  • Every stop has its own address. Stop 4 is /pages/deep-sea-quest#stop-4 — paste it straight into Google Classroom.
  • Progress is remembered on the device, so a class can do one stop a week and pick up where it left off.
  • Each stop runs 10–15 minutes. The finale needs all six done first.

The six stops

1. The Sunken ReefCoral is an animal with tiny algae living inside it. The algae make the coral's food and its colour. Water that stays too warm drives the algae out, and the coral turns white.2. The Twilight DropSunlight only reaches the top of the ocean. Down to about 200 metres there is enough light to see by. Below that it fades to a faint blue, and deeper still no sunlight reaches at all.3. Chomp ChasmThe sea floor has shapes with names, the same as dry land does. Near the coast it is shallow and gently sloping. Far out it is a wide flat plain. Mountains rise from it, and trenches cut down below it.4. Pearl GrottoAlmost all of Earth's water is salt water in the ocean. Most of the fresh water is frozen in ice caps and glaciers. Only a small part of all Earth's water is liquid fresh water in rivers, lakes and underground.5. The Silent DeepSound travels well through water. A ship sends a pulse of sound down and times how long the echo takes to come back. The longer the wait, the deeper the water.6. The Anglerfish AbyssNo sunlight reaches the deep ocean. The only light down there is light that animals make inside their own bodies. That is called bioluminescence.

What the kit adds

The adventure is free and always will be. The Deep Sea Quest kit adds the part a screen cannot do: six real specimens, six Digs that come sealed with the label scratched off, six Gemlings in a blind bag, and the printed map with Aqualing on it. Finish a stop online and that location's Dig is yours to open for real.

Finished Deep Sea Quest? The online adventure is the half you can do today. The other half is a real specimen in your hand — six of them, one per stop, sealed in a Dig with the label scratched off.
