Project Goals
– Studying the trajectories of movement of various bodies;
– Studying the features of the movement of a helicopter and an airplane.
Teacher’s Guide
– In this project, each student works individually;
– Make a brief overview of the theoretical part and move on to the practical;
– Students must make up an airplane and a helicopter and tell the difference in movement.
Safety in Steam Lessons
Before starting a lesson, the teacher is advised to familiarize himself with the safety precautions. If necessary (in the case of using the items specified in the TB), conduct a brief briefing for students. Follow this link Safety in Steam Lessons
Theoretical part
All bodies move in space along a certain line. The line that any object creates during this movement is called the motion path. For example, you might notice the line that an airplane leaves behind. Or footprints in the sand left by a car, etc.

In this lesson, we will track the trajectories of a helicopter and an airplane. Helicopters fly in the air through spinning blades used to push upwards. Using enough of it, the ship can overcome the gravity that pulls the object toward Earth. Helicopter wings with rotating blades, unlike traditional aircraft, are called propeller wings.

This tutorial uses a simple paper helicopter called a whirlwind bird. Unlike a real helicopter, the whirlwind bird does not have an engine that spins the blades. However, their unusual shape makes the blades spin as they fall. When this whirlwind bird falls, an additional lift force slows it down. So if you drop this paper down, it will slowly drop down. Adding more paper clips to the swirl bird increases its weight. The earth pulls him so strongly towards the earth that a “vortex bird” with extra paper clips falls faster than the same “vortex bird” with fewer paper clips.
Practical part
1. Download and print a sample (whirlwind bird).
2. Download link – whirlwind bird
3. Follow the instructions on the template to cut and fold the swirl bird.
4. Cut along solid lines.
5. Fold parts A and B along the dotted lines inward. Fold part C up to hold parts A and B in place.
6. Fold part D along the broken line towards you. Fold part E to the other side of the broken line.
7. After cutting and gluing, the vortex should rotate like a helicopter if we drop the bird from a small height.
After we are ready, we can paint in the desired color. Now we need to make a plane to compare them.
1. We take an A4 sheet and fold it into the center into two triangles so that the edges are equal.
2. Fold down one triangle.
3. From the triangle to the center, as in the picture, add two more triangles, not reaching 2 cm to the end of the previous triangle.
4. Fold up a small triangle 2 cm in the center.
5. Fold along the length in the center.
6. At the nose of the aircraft, we fold it to the sides, as in the picture.
7. We launch when our plane is ready. We can also paint our aircraft in different colors.
When our plane and helicopter are ready, we launch them one by one. After practice, summarize the lesson by asking students questions.
– How does a helicopter fly?
– How does the plane fly?
– So, is there a difference between them?
In this project, each student will be awarded a STEAM title in two categories:
– You managed to explain the difference between the flight of a helicopter and an airplane, you are a real scientist – a future physicist!
– You independently designed and launched a model of an airplane and a helicopter, you are a future aircraft designer!
Evaluation
PBL grading criterion: Project-based learning is a learning method in which students acquire knowledge and skills by working on a single project to explore and find an answer to a genuine, interesting, and complex question, problem, or challenge.
