Floating, Sinking & Motion Super Integrated Thematic Unit Floating, Sinking & Motion is a theme that can lend itself to a wide range of inter-connected activities and makes for a great rich topic. As pupils examine, contrast and investigate Floating, Sinking & Motion skills they can practise these in authentic learning contexts within the school and/or wider community. They can interact with leaders from the local or national community and be mentoed in their own skills and attitudes. This topic would be great for more senior pupils in the school as they take on roles of mentoring or assisting younger pupils or juniior classes. We have made a number of references to Wikipedia articles within the body of this article.

The
Basilisk Lizard, nicknamed the 'Jesus Christ' Lizard, has the amazing
ability to be able to walk upon the water. The real basilisk lizard
may not be able to kill you by looking at you, like the mythical basilisk.
But it is still a pretty weird beast. When scared the little lizard runs away on its back legs. It can even
run across water. Here's how it does it - its feet have a very broad
sole and a fringe on its toes. However it only works when the lizard
runs fast, as it slows down it starts to go through the surface and then
has to swim. It can run up to one hundred feet across any body
of water. The Basilisk's feet, push down, creating a hollow almost like
an air bubble in the water. Gathering enough speed, it uses the air to
push forward. The lizard pulls its foot upward before the hollow breaks..plunging
it into the water. to do this the toes on the foot are pulled together
and the entire foot is pulled upward. That means the foot is surrounded
only by air as
the animal quickly pulls its foot out of the hole. |
For a human to do what the basilisk lizard does, they would have to run 65 miles an hour and expend 15 times more energy than a human is able to expend. The Basilisk Lizards are found in the Central and South American rainforests,
usually near rivers or streams. Their diet mainly consists of insects,
small invertebrates, flowers, and smaller animals, such as snakes,
birds, and fish. They must beware of birds, snakes, fish, and other
reptiles and mammals. Their colours can range from green. to brown,
to striped, even to red. |

Leonardo de Vinci (the famous inventor, thinker and artist) may have wondered about this, and so he draw his invention for how this could happen. Do you think it worked? Today there is a firm selling its way of walking on water: The Vacation Gadget Man, Water Gadgets! Hydro Bronc |
World's Biggest Balloon: Space bid for world's biggest manned balloon. See also more links here Plants that Float
Cottonwood seeds and milkweed seeds also float in clouds of fluff. On a windy day, floating seeds can be blown for kilometres. More information here. Other plants equip their seeds to float in the ocean. Salt would normally kill plants so these seeds have great protection. One example is the coconut, check them out here. |

What
about living in a home that floats? This is a picture of a narrowboat,
sometimes called a canal boat or house boat. Wherever there are canals,

You may have learned to swim with the help of a swimming float. When were you last enjoying yourself watching a whole lot of parade floats? There has been need at times for floating drydocks for the repair of ships. Humans have floating ribs in them and many guns have a floating breech.

Sinking... the opposite of Floating! Let's have a look at the idea of sinking now. In conservation terms the idea of carbon dixode sinks has become important. Where land has sunk you can find sink holes (sink holes from teAra encyclopeadia), in some cases sink seas, and houses can get "eaten" by sinkholes (News Article). Computers rely on heat sinks, but so do a lot of other microprocessors (ships often found in electronic equipment). Towns and cities are sinking, take Venice for instance.

New Zealand Sinking! Harwoods hole is the largest natural sink hole in New Zealand, and at a depth of 176m (15m in diameter) its the largest in the southern hemisphere. It is at the top of Takaka Hill and is part of an intricate (complicated) network of hidden limestone caves that run through the hill. Cavers can abseil down into Harwood's depths and emerge at a cave system near Takaka. This is often called spelunking. In another famous sinking, in 1985 French Commandoes sunk the Rainbow Warrior, a Greenpeace boat. And then in 1968 one of the more well known New Zealand disasters, the sinking of the Wahine.(Another link here, more shipping disasters here) |
