Focusing on Forces of Flight

1. Focusing on Forces of Flight Virginia Rhame NWAESC Science Specialist October 31, 2013 ACC 2013

2. Goals of Session • Consider science pedagogy and how to best integrate activities and demonstrations • Be ready to take advantage of the free resources NASA has for educators • Add some new activities related to force and motion to your repertoire What are the forces related to flight?

3. Direction of Science Education in Arkansas What about textbooks?

4. Eight Practices- Framework ch 3, NGSS Appendix F *Note that in doing science or engineering, the practices are used iteratively and in combination; they are not linear steps to be taught in order. Asking questions (science) and defining problems (engineering) Design and using models Planning and carrying out investigations Analyzing and interpreting data Using mathematics and computational thinking Developing explanations (science) and designing solutions (engineering) Engaging in argument Obtaining, evaluating, and communicating information

5. The 5-E Model (bybee, BSCS)

6. Food for Thought. . . • “People don’t learn from their experiences; they learn from processing their experiences.” • --Bob Garmston • How might students have an opportunity to process their experiences inthe classroom?

7. Activities Exploring Air Pressure: • Before the demonstrations. . . • What are some misconceptions students might have about AIR? • Demonstrations. . . • Dunked Napkin Demonstration • Air Power Demonstration

8. Activities Exploring Gravity: • Before we demonstrate. . . • What are some misconceptions students might have about gravity? • Demonstrations. . . • Can Drop Demonstration • Feather and Hammer Drop on Moon

9. Another Gravity Demonstration • Fluttering Fun • Mold a small amount of clay into ball and press onto table. • Place pencil into clay with eraser side up. • Predict where you think butterfly will balance. • Balance butterfly on top of eraser • Change the center of balance by attaching paper clips and/or washers in different areas. Experiment with different combinations and locations. What do you notice? • Turn the pencil point up. Now try to balance it with and without weights. What do you notice?

10. Activities Exploring Lift: • Chin-Ups • Predict what you think will happen when you place a strip of paper under chin and blow. • Now, do it! • Table Talk: Draw what happened and suggest a possible “Why” • Paper Tent and Straw • Fold a piece of paper in half. • Predict what will happen when you use a straw to blow underneath the paper. • Table talk: Draw and suggest a possible “why”

11. More Activities Exploring Lift: • Ball and Straw • Predict what you think will happen when you release a golf ball above a straw while blowing through the straw. • Hold straw with short end pointing up. • Hold golf ball above short end. Blow. Release golf ball. • Table Talk: What is happening? Why? • Ping Pong Ball and Funnel • Predict what you think will happen when you hold a ping pong ball in a funnel while the funnel is pointed downward, blowing through the funnel and then releasing the ball. • Try it! • Table Talk: What is happening? Why?

12. Activities Exploring Thrust: • Balloon Jets • Measure out about 3 meters of fishing line. Thread piece of straw on line. Blow up a balloon but just pinch it shut (don’t tie it). Tape piece of straw lengthwise to balloon. Release balloon. • Predict what would happen with a larger or smaller balloon. • Table Talk: What is going on here? Why does balloon move forward from air coming out the back? • Moving Fan Demonstration • Predict what you think will happen when I turn this fan on. • Table Talk: What did happen? Why?

13. Activities Exploring Drag: • Parachute Activity: Not going to do it, but I’ve included it in packet. • Flaps on a plane increase drag.

14. Final THoughts. . . • Any questions? Misconceptions that haven’t been addressed yet? • Thanks! Have a great day!
