Plastic bowl with lid per Cub

Black spray paint 

Electrical wire (pre-solder to LED and veroboard)

3W White LED per Cub

2 AA Batteries per Cub

Veroboard

Insulation tape

Split pins

Metal paper clips 

Pin

Constellation template (attached) 

Spray paint the bowls and lid black.

In the bowl, punch small pin holes in the shape of the constellations, using the template below.

On the lid, build the circuit as follows:

• Tape/glue the LED withtwo wires to the centre of the lid
• Connect the batteries together with insulation tape, facing opposite directions and touching the veroboard piece provided.  Test that current is flowing
  
• Place the small veroboards connected to LED onto a strip of insulation and attach to the battery pack
  

• Bend the paper clip into the shape of a switch.  Measure the distance and place the two split pins at the measured distance by pushing the legs through the lid
  
• Connect the wires to the split pins

• Paper clip acts as the switch

• Attach battery pack to side of the lid and tape in place

• Place the bowl back on the lid.  Use the paper clip to switch on and off

Have an old computer or a variety of broken electronic devices that can be taken apart to show the Cubs the various components.  See how many they can remember and  pass the items around if possible.

Create a maze out of staves (outside) or straws/earbuds/skewers (indoors).

Cubs (in teams of 2) to write instructions to get from the centre of the maze to the exit (eg. walk forward two steps, turn right 90 degrees, etc.). 

When they believe the instructions are ready, one member of the team goes to the starting point of the maze (or places an object in the centre of the maze if indoors)

The second member of the team calls out the instructions in order.  The Cub in the maze must follow the instructions EXACTLY.  Challenge them if the instructions aren't specific enough. 

If their programme is not correct, they can go back and rework it and try again. 

Wiring a Plug

1. Bare the ends of the three wires inside the electrical cord for about half a centimeter, by cutting away the plastic insulation.

2. Gently twist the strands of copper wire with your fingers until each strand is tight.

3. Fold over the twisted strands.

4. Remove the plug cover by either "snapping" or unscrewing it.

5. Unscrew the little screws on each of the plug's pins.

6. Insert the twisted copper wires into the holes in the pins.

7. The green and yellow wire must always be inserted into the top pin.

8. The blue wire is inserted into the left pin (the pin is marked with a blue spot or the letter N).

9. The brown wire is inserted into the right pin (the pin is marked with a brown spot or the letter L)

10. Tighten the little screw on each of the plug's pins.

11. Make sure the electrical cord is firmly gripped by the arrestor clips.

12. Replace the cover of the plug.

Set up a string from a high point down to the ground.

Each Cub to blow up their balloon and tape a straw onto the side

Each Cub to take turns to launch their rocket by placing the string through the straw and letting go of the mouth of the balloon (allowing the air to escape).

Remember to hold the string taut so that the balloon travels up the string
