Project Goals
– Study of the movement of bodies with different trajectories;
– Pay attention to creativity by creating rackets in various designs.
Teacher’s Guide
– В этом проекте каждый ученик работает индивидуально (можно выполнять в группе, если есть затруднения);
– Сделайте краткий обзор теоретической части и переходите к практической;
– Объясните учащимся, что важно делать ракету в любом дизайне, а не только по инструкции.
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 a line that an airplane or rocket leaves behind. Or the footprint left by a car that drives on sand or dirt.

This lesson will study how a rocket flies and its trajectory. The rocket moves under the action of the pushing force of the gas. When he releases gas from his “tail” down, he begins to fly in the opposite direction, that is, up. The force that lifts a ship is called the reactive force. The principle of rocket flight can be seen very well with the help of a balloon. Blow it out and let it go The ball flies under the influence of a stream of air that pushes it. When we make a rocket, we will launch it by blowing it into a tube, thereby using reactive power. At the end of the lesson, we will observe the trajectory of each rocket.
Practical part
Step 1. Fold one sheet of paper into a small rectangle and divide it into four parts. This will allow you to create four rockets.
Step 2 Wrap one of the paper rectangles around the tube to form a cylinder.
Step 3. Tape the cylinder to prevent it from opening (but you can’t stick it to the tube).
Step 4 Remove the cylinder from the tube. Pinch one end of the cylinder and cover it with tape. (This is the “front” end of the rocket.) Leave the other end open.
Step 5 Create the back of the rocket. From another sheet of paper, cut out four triangles (at a 90-degree angle in one corner).
Step 6. Draw a line parallel to one side of the triangle.
Step 7 Now fold the triangle along this line.
Step 8 Glue the flat piece to the side of the cylinder, and the open end.
Step 9 Repeat these steps for another triangle and glue it to the cylinder on the opposite side. The result should be four ribs that form a “+” shape when looking at the rocket from both ends. If necessary, fold the walls so that they are 90 degrees apart.
Step 10 The rocket can be styled differently if desired.
Step 11. There should be enough space in front of you and there should be no obstacles. Get ready to launch the first rocket! Put it in a straw. Point the straw forward and then inflate it as hard as you can.
Step 12 Watch the rocket as it flies. Run it a few times to see if the rocket flies the same. If you want to record the range of a rocket, shoot it from the same spot each time and measure it with tape to the landing area.
Step 13 Make a few more different rocket launchers with the rest of the paper. Place the new rocket on the straw and launch it.
Triangular tips, and fins, made on the “tail” of the rocket, help to keep the rocket in a constant or uniform direction. If the rocket turns a little, it will direct the rocket’s movement in the original direction. When you launch a rocket with the help of the wind, it moves along a certain trajectory, rising. See how they move, paying attention to this trajectory?
In this project, each student will be awarded a STEAM title in two categories:
– You managed to create a rocket with your own hands and launch it into the air, you are a real engineer!
– You created incredibly beautiful rockets from your imagination, you are a creative person!
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 answer a genuine, interesting, and complex question, problem, or challenge.
