Once you have got your seismometer running you will need to cover the sensor with a draft-proof box.
If the sensor is on display then this will need to be a box with at leats two transparent sides (Front and Top). Suggested materials for this are toughened glass or perspex. Your school workshop whould be able to help here. The other three sides of box can be made of any suitable material (eg MDF or Plywood sheet).
If the sensor is in an out of sight location then a simple cardboard box will suffice
