Criteria: How to make a whirligig fall more

slowly

Constraints: Must fit on the back of a cereal

box; paperclips

Summary:

• template: pattern

Thinking about how Things Fall

o Demonstration notes worksheeto Observe 3 short demonstrations o Record both your predictions and observations

Demonstration Predict Observe Compare#1 Describe the event here

Completing the Form

o Predict – I will explain to you what I am going to do during the demonstration. You will predict what you think will happen.

Demonstration #3

o A volunteer and myself will drop seven coffee filters that are taped together like a flower, a single coffee filter, and a stack of seven coffee filters

o All items will be dropped from the same height at the same time

Compare

o Compare your predictions to what you observedo Note what you predicted and what surprised you

Conference

o Share all your predictions and observations with all the people at your table

o Be sure to let everyone have a turn to shareo Try to explain why the objects dropped the way they dido Discuss what you think you knowo Discuss what you think you still need to know

What is our

Evidence?

What does it mean for the challenge?

• the thinner and bigger the item, the slower it falls• objects fall at same speed no matter the mass

• Make a bigger flower (20 filters) and drop it with the little flower• upside down flowers• how does mass influence the speed of drop

• how gravity affects how objects fall• aerodynamics (how wind changes how things fall)

• When we dropped the flower it landed last• dropped coffee cans with no marbles and marbles

• whirligig can trap air• space in between the materials• greater surface area• heavy or light doesn’t really make a difference.

learning?

What is our

Evidence?

What does it mean for the challenge?

• if two objects are dropped at the same time, they will fall at the same rate• Heavier things fall faster (more mass)

• how do aerodynamics play into the falling of objects (wind)

• Dropped coffee cans with/without marbles from a higher height

• how wind and air can change speed

• effects of mass on gravity

• flower flipped over and dropped slower than the other objects

• mass doesn’t really affect speed of fall

• the toy will need more surface area in order to fall more slowly

• whirligig should be light weight

What is our

Evidence?

What does it mean for the challenge?

• The more mass of an object the faster it falls• Two objects with different mass – both fall at the same speed.

• drop coffee cans – one with marbles and one without.

• Gravity pulls the objects down

• Book fell faster than paper

• mass won’t matter in the speed of fall
