Eric Mazur
Born
Mazur’s Peer Instruction begins with a conceptual question and an individual vote. Students compare reasons with a neighbor before voting again. What makes the sequence useful is the contrast between the two votes, because disagreement gives the class something to investigate before the explanation arrives.

Derek Muller
Muller’s physics education research compared ways to present misconceptions in educational videos. In “How Does a Slinky Fall?” he asks people what they expect to happen when a hanging Slinky is released. Before watching the answer, predict which end moves first and name a detail you would look for in slow motion.

Katherine Perkins
The PhET simulations Perkins directs give students a way to try out a specific prediction. Pause with one setting fixed, ask what should change if you move one control, then compare the result with your idea. That is a more useful question to bring to a simulation than simply asking whether you can finish the activity.

Jane Goodall
Born
Roots & Shoots asks young people to observe and map their community before selecting a project. The map offers a way to ask where a problem occurs and who or what uses the same space. It carries the spirit of Goodall’s fieldwork into a setting a group can revisit for a second look.

Carl Sagan
Born
The Fine Art of Baloney Detection in The Demon-Haunted World gives readers questions to bring to a striking claim. Is there independent confirmation, and what else might explain the same observation? Try asking both before deciding how convincing the first explanation is.

Ainissa Ramirez
The Alchemy of Us starts with physical things and follows their consequences. Ramirez uses materials science to turn a familiar artifact into a two-way question: what properties made the invention possible, and how did it then change the people using it? That is a practical way to pick a first object to investigate.

Jocelyn Bell Burnell
Born
Bell Burnell’s public talk about the pulsar discovery follows what she did after noticing an unexpected signal. The example gives learners a question to borrow when a graph shows something strange. What would I have to see again to tell a real signal from a stray feature in the recording?

Emily Calandrelli
Emily’s Wonder Lab gives young viewers something concrete to test. In the egg-in-a-bottle experiment, the interesting question is what changed inside the bottle. Ask for a prediction before watching it happen, and keep the explanation open until the viewer has had a chance to describe what they saw.

Alan Alda
Born
Alda’s Flame Challenge asked scientists to explain a flame in a way a child could understand, and children helped judge the results. That changes who gets to decide whether an answer works. Start with a short question about a familiar thing, then see what remains unclear after the first explanation.

Frank Oppenheimer
Born
At the Exploratorium, Oppenheimer wanted visitors to develop the habit of asking questions through hands-on encounters. Change a setting, watch what happens, and compare a second try. The museum approach is worth following when a demonstration would otherwise be over by the time someone thinks of what to ask.

Rachel Carson
Born
The Sense of Wonder makes time outdoors an occasion for noticing together. Carson’s approach leaves space for a question to arise from something a child actually sees or hears. Pick one place to revisit, and the next useful question may be what changed since last time.

Hank Green
Born
SciShow often starts with a small question about something ordinary or puzzling. Green helped build the format around taking such questions seriously. It is a good model for asking the more useful version of a broad question, one tied to a particular event or observation that science can investigate.

Steve Spangler
The Windbag Wonders activity guide asks learners to name the question and make a prediction. It is a short way to turn a demonstration into a test. Try getting each person to tell you what result they expect before anyone reveals the way to do it.
