Investigate Water Power


Materials:
- Foil Dish
- Scissors
- Pencil
- Tape
- Piece of string
- Weight of some sort

Procedure:
1. Make 8 equally spaced cuts around the edge and towards the centre of the plate. End each about 1 cm from the centre.
2. Fold one edge of each to make small ledges.
3. Puch a hole in the middle and push the pencil through. Tape it into place.
4. Let the pencil rest between your fingers and thumbs and hold the wheel under a stream of water (running tap). (What happens when the rate of flow is increased or reduced?)
5. Tie a piece of string to the pencil and attach the weight to the other end. The water wheel should wind the weight up to the pencil. (How much can be lifted? What happens when the load is too heavy?)

Investigative Flight




Materials:
- Paper
- Scissors
- Straw
- Tape
- Ruler

Procedure:
1. Cut a piece of paper 5 cm by 15 cm. Hold it against your lower lip.
2. Now blow across the surface. What happens?
3. Use another piece of paper and this time bend it to the shape of a wing, curved on top and flat at the bottom. Tape the ends together.
4. Put a straw through the wider end and let the paper hang down.
5. Blow over the wing. What happens?

Procedure:
1. Cut two strips of paper; one 2 cm by 24cm and the other 1.5 cm by 18 cm.
2. Make each strip into a loop by overlapping the edges by 1 cm and taping them.
3. Insert a straw into the two ‘pockets’ you have made.
4. Throw it like a spear. Compare it with throwing a straw on its own.

Dragon


Dragon by The Tail

Player line up one behind the other grassping the waist of the person in front. The person at the front of the dragon has to try to touch the person at the end of the tail, dragging the dragon as he or she tries to do so. Anyone who lets go is out of the game.
When the person at the front succeeds in touching the person at the end, he or she goes to the end of the line and the next person becomes the head.


Dragon Tiggy
When a person is tagged by ‘he’, the two join hands and so on until all players are joined to form one long dragon.

Dragon Board Game
Make a board game to follow the sequence of a favourite dragon story. Or, make a ‘dragons and ladders’ game. Or make a trail game to find the dragon’s treasure. Or, make up a variation of Battles.
