Collage
Collage is the application of coloured pieces of paper glued, stuck, adhered to a canvas to form a picture. A good source of coloured paper is old magazines. It is a great rainy day activity, and needs only a backing sheet
of paper or board, glue and a source of coloured paper and imagination.
You can mix it with crayons, you can add some paint you can do it anyold how.

Construction
This is for the budding engineers, particulaly with a mechanical and civil leaning.
Civil Part
This part of the construction project involves making the pylon, the upright that holds the bridge up on the right hand side and the bridge or span section.
These are the Stationery Items, that are structurally important.
Mechanical Part
This part of the construction project involves making the hinge, and the raise lower hydraulic section.
The hydraulic lifting mechanism uses syringes with out the needles. Try using thin long syringes for the hand driven lifter, and short fat syringes for the actual mechanical lifter on the bridge. this will give you Mechanical
advantage.

Electrical
This is a fun project to do because lighthouses are becoming used less and less as technology is used more and more. Lighthouses flash their light on and off in a manner that let seafarers identify where they are. They
flash their light a number of times in a certain period. So a lighthouse may be described as Fl 3 2min meaning flashing 3 times every 2 minutes. Sometimes it is necessary for a lighthouse to stay on and "flash" off a number of times. When this
happens a lighthouse is said to Occulting and would be shown on a chart as Oc 3 2 min meaning Occulting 3 times every 2 minutes.
Many lighthouses are located on islands off the coast. This is so ships don't run into the islands because it doesn't do the islands any good, the penguins get scared, and so good ships further out to sea can see the lighthouses.
To build this project you need to make your island with a hill on it. Lighthouses generally go on hills so they are higher up. When you have built the island, then you can start constucting the lighthouse. This is made out of a
cardboard tube out of a roll of foil, or plastic wrap.

Next we need to make the electrical lamp circuit
This diagram is what electrical engineers use to build electrical installations such as power stations. To build this you will need a battery and battery holder, some electrical wire, and a globe in a globe holder
