Notice & predict
Same paper, new shape
Predict which equal-paper shape will arrive first.
Curiosity Bundle
How Does a Parachute Slow Down?
Same paper. Same starting height. Does changing its shape change the fall?
Start with a prediction, compare repeated drops, then follow the idea of drag to a spacecraft landing on Mars. Both readings belong to the exploration.
IgniteWhich paper will arrive first?
Offer one puzzle. Keep the first explanation open.
Offer one puzzle. Leave room for a guess.
Hold two equal paper squares, one flat and one crumpled. Ask, "They started as the same paper. Which will reach the floor first?" Wait for a prediction before dropping them.
Another way to begin
Show a spread-out coffee filter and a gently crumpled one. Ask, "Could changing only the shape change how it falls?"
Use two equal sheets of scrap paper. The test works indoors and needs no parachute or special filter.
KindleSame paper, new shape
Save the prediction before reading. A sketch is enough to begin.
ReadFollow the clue a little further
Follow the falling-paper clue into drag, then travel with the idea to a Mars landing.
DoCompare the whole fall
Let the observation change the explanation. Record a missing or surprising result honestly.
Investigation
Compare the whole fall
Compare flat and crumpled paper safely.
CheckReturn to the first idea
Revisit the investigation and both readings. Use the parent answers as conversation notes.
A light check
What would you change now?
Explain drag with light prompts.
