To create a simple machine to help the school get water from a tank 10m below the ground, you will need the following materials:

1. Rope
2. Jerrycan
3. Metallic bar
4. Wheel of a bicycle

Steps to create the machine:

1. Tie one end of the rope to the handle of the jerrycan.
2. Attach the metallic bar to the other end of the rope.
3. Place the wheel of the bicycle on the ground near the tank.
4. Lower the metallic bar with the jerrycan attached into the tank.

Materials:

- Rope
- Jerrycan
- Metallic bar
- Wheel from a bicycle
- Pulley (optional)

Steps:

1. Build the Frame:
- Bend the metallic bar into a U-shape and insert it into the ground, creating a support frame.
- Attach the bicycle wheel to the top of the frame using bolts or clamps.

2. Attach the Rope:
- Tie one end of the rope to the handle of the jerrycan.
- Run the rope over the bicycle wheel and then attach it to the support frame.

3. Install the Pulley (Optional):
- If desired, attach a pulley to the support frame to reduce the force required to pull the rope.

How to Operate:

1. Fill the jerrycan with water.
2. Pull on the rope to lift the jerrycan out of the tank.
3. Use the pulley (if installed) to reduce the effort required.
4. Once the jerrycan reaches the ground, release the rope to lower it.
5. Untie the rope from the jerrycan and pour the water into a storage container.
