Philip enjoys tae kwon do and playing football and basketball. He also plays tuba in his school's band. He hopes to become a history professor someday, stating, "I absolutely love history."
Philip is interested in the mold spores found in household dust. After seeing the price difference in air filters for houses with central air conditioning, he wondered whether expensive filters are any better for trapping mold spores than cheaper filters.
Philip set out petri dishes in five houses and let dust particles settle on them to test the background level of mold spores in each house. He then swapped the air filters for inexpensive versions and tested mold spore levels again. He tested mold spore levels in the houses a third time after changing the filters for expensive ones. Philip discovered that significantly fewer mold spores were present in each house when it was fitted with the expensive filters than when the inexpensive filters were in place.
