I gwblhau'r arbrawf hwn bydd yn rhaid i chi greu cwch naturiol fel y gwelir yn her 3 ar ein prif dudalen o’r wefan. Os nad ydych wedi gwneud cwch eto cliciwch ar y ddolen isod i fynd i ein prif dudalen.
Ar ôl i chi greu eich cwch byddwch yn barod i roi cynnig ar yr arbrawf hwn .
Am her ychwanegol beth am ychwanegu cargo?
Llenwch eich cwch gyda'r hyn y gallwch chi ddod o hyd iddo. Gallai fod yn gerrig mân, cnau, dail neu aeron
Ydych chi'n dal i arnofio neu ydy o wedi suddo gyda'r pwysau ychwanegol? Rhestrwch eich canfyddiadau i'r graff wedi atodi!

For an extra challenge why not add some cargo?
Load your boat with what ever you can find outside it could be small pebbles, nuts, leaves or berries
