1. Thursday October 14 th Please have your yellow Cookie Reflection homework out so I can stamp it at the beginning of class. Agenda: Big Island Adventure Check/Turn in Homework Introduce New Challenge Demonstrations Project Board

2. Whirligig Challenge Learning Set 3 Lesson 3.1

3. The Whirligig Challenge10/14/10 11 Criteria: How to make a whirligig fall more slowly Constraints: Must fit on the back of a cereal box; paperclips Summary: template:pattern

4. Thinking about how Things Fall oDemonstration notes worksheet oObserve 3 short demonstrations oRecord both your predictions and observations DemonstrationPredictObserveCompare #1 Describe the event here

5. Completing the Form oPredict – I will explain to you what I am going to do during the demonstration. You will predict what you think will happen. DemonstrationPredictObserveCompare #1 Describe the event here

6. Completing the Form oObserve – You will observe the demonstration and record what you see and hear. DemonstrationPredictObserveCompare #1 Describe the event here

7. Demonstration 1 oI will drop a book and a piece of paper from the same height oBoth will be held parallel to the floor oFill out the prediction section of Demonstration #1 DemonstrationPredictObserveCompare #1 Describe the event here Fill out what you will think will happen here!

8. Demonstration 1 oWatch demonstration oRecord what you saw happen in the observe section of Demonstration #1 DemonstrationPredictObserveCompare #1 Describe the event here Fill out what you saw happen here!

9. Demonstration 2 oI will drop a single coffee filter and a stack of 7 coffee filters oItems will be dropped from the same height oThe bottom will be facing the floor DemonstrationPredictObserveCompare #1 Describe the event here #2 Describe the event here Fill out what you will think will happen here!

10. Demonstration #2 oWatch demonstration oRecord what you saw happen in the observe section of Demonstration #1 DemonstrationPredictObserveCompare #1 Describe the event here #2 Describe the event here Fill out what you saw happen here!

11. Demonstration #3 oA 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 oAll items will be dropped from the same height at the same time DemonstrationPredictObserveCompare #1 Describe the event here #2 Describe the event here #3 Describe the event here Fill out what you will think will happen here!

12. Compare oCompare your predictions to what you observed oNote what you predicted and what surprised you

13. Conference oShare all your predictions and observations with all the people at your table oBe sure to let everyone have a turn to share oTry to explain why the objects dropped the way they did oDiscuss what you think you know oDiscuss what you think you still need to know

14. The Whirligig Challenge10/14/10 11 Criteria: How to make a whirligig fall more slowly Constraints: Must fit on the back of a cereal box Summary: template:pattern Project Board: a place to plan and keep track of your project

15. Project Board 5/6B Whar What do we think we know? What do we need to investigate? What are we learning? What is our Evidence? What does it mean for the challenge? Whirligig Challenge

16. Project Board 1/2B Whar What do we think we know? What do we need to investigate? What are we learning? 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. Whirligig Challenge

17. Project Board 1/2A Whar What do we think we know? What do we need to investigate? What are we 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 Whirligig Challenge

18. Project Board 3/4A Whar What do we think we know? What do we need to investigate? What are we learning? 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 Whirligig Challenge
