Fan-tastic Forces Activity Demo

## TL;DR

Students will engage in a demonstration activity to explore the forces of flight, including lift, weight, drag, and thrust.

## Key Insights

• π€ The Fantastic Forces activity allows students to explore and understand the forces of flight through hands-on demonstrations.
• ποΈ Different materials and shapes can be used to determine their susceptibility to lift, weight, drag, and thrust.
• π΄οΈ The activity can be adapted to suit different classroom needs and grade levels.
• ποΈ Lift, weight, drag, and thrust are essential forces that affect aircraft design.
• ποΈ The lift demonstration shows how different note cards exhibit varying degrees of lift when subjected to airflow.
• ποΈ The weight demonstration highlights how objects of equal size can have different weights.
• π§βπ Demonstration of drag helps students observe how different shapes experience varying levels of resistance.

## Transcript

hello my name is Adeline dine heart and I am an education specialist here at NASA Langley Research Center today I'll be demonstrating the fantastic forces activity where students will have the opportunity to use different materials and shapes of materials to determine which are the most and least susceptible to lift weight drag and thrust fantastic...

### Q: How can students determine which materials are most susceptible to lift, weight, drag, and thrust?

Students can construct different shapes using materials like straws, index cards, and plastic. They can then perform demonstrations to observe the effects of lift, weight, drag, and thrust on each shape.

### Q: What is the purpose of the lift demonstration?

The lift demonstration helps students understand how lift affects aircraft. By holding the note cards parallel to the ground and turning on the fan, one of the note cards will exhibit greater lift by raising higher into the air.

### Q: How can students demonstrate weight or gravity?

Students can hold two objects of equal size but different weights by the straws and have them face perpendicular to the ground. When the fan is turned on, one of the objects will exhibit less weight by being pushed closer to the person holding it.

### Q: How can drag be demonstrated during the activity?

To demonstrate drag, students hold the demonstration by the center straw, with the objects facing the fan. When the fan is turned on, one of the shapes will experience more drag by being pushed closer to the person, while the other shape will move closer to the fan.

## Summary & Key Takeaways

• Students will use various materials and shapes to determine which are most and least susceptible to lift, weight, drag, and thrust.

• The activity can be adapted to fit different classroom needs.

• The demonstration includes constructing different shapes and performing demonstrations for lift, weight, drag, and thrust.
