How could a self-directed learner investigate the effects of gravity on objects with different masses? (1 point)

He would decide what object he wanted to investigate, identity resources that could provide needed information,
and figure out what steps to take.
• He would only ask his teacher for ideas about investigating gravity and air resistance
• He would only follow the instructions in his science book.
• He would only join a team that is working on a project about gravity and air resistance
