Everything here is free to use, print and photocopy for a class. No login, no sign-up, and nothing about your pupils is collected — the quiz and certificate run entirely on the device.
Ages 6–10 · 30 minutes. Draw a cross-section of the coast from beach to open sea: mangrove creek, seagrass meadow, coral reef, deep water. Ask pupils to place animals where they belong — crab in the mangrove, tafi in the seagrass, changu on the reef, tuna in the deep.
Discussion: what happens to the reef fish if the seagrass nursery disappears? Follow the chain out loud.
Ages 9–13 · one week. Find the tide table for your nearest port and chart high and low tides for seven days on a wall. Ask pupils to predict day eight before checking.
Discussion: why two high tides a day rather than one? Use a ball and a torch to show the two bulges.
Ages 6–10 · 20 minutes. Sort cards into two piles. Dolphin, turtle, octopus, crab, seahorse, shark, sea star, squid. Only the seahorse, shark and the true fish belong in one pile.
Discussion: what makes a fish a fish? Gills, fins, scales, cold blood, eggs — then look at which rules the seahorse and the shark break.
Ages 11–15 · 45 minutes. Use counters as fish in two identical "seas". Fish one every round; leave the other closed for three rounds, then fish it. Double the remaining counters between rounds to represent breeding.
Discussion: which sea ends up with more fish, and why? This is exactly the logic behind octopus closures on the Kenyan coast.
Ages 9–15 · one week. Have pupils log every piece of plastic they use for two days, then trace the route from bin to drain to river to sea for three of them.
Project: a beach or schoolyard clean-up, sorting and counting the categories found. Counting turns tidying into science.
Ages 11–15. If you are near the coast, invite a local fisherman or a Beach Management Unit member to class. Pupils prepare five questions in advance.
Why it works: knowledge that has never been written down is the most interesting thing in the room, and it is sitting with the person who goes out at 04:30.
Print it. Every page here prints cleanly in black and white. Use your browser's print function; the navigation and buttons drop away automatically.
No accounts, no data. Pupils do not sign in. The quiz score and the certificate name stay in the browser and are gone when the tab closes. Nothing about a child reaches us or anyone else.
Corrections welcome. If you are a teacher or a marine scientist and you find something wrong here, please tell us on WhatsApp and we will fix it. Accuracy matters more to us than looking clever.
