This powerpoint presentation was created by Hillary Belen Chua in 5R. The document describes an experiment conducted to test for drafts in a house. The experiment involved using cling film, tape, and a pencil to create a draft tester that was used to test various doors and windows. The main findings were that the front door showed a soft breeze while Window 1 showed a much stronger breeze. The conclusion was that the house was not as drafty as initially thought.
