What materials are used in the two-stage rocket?

What materials are used in the two-stage rocket?

MATERIALS and TOOLS:

• 2 long party balloons (round balloon will not work)
• Nylon monofilament fishing line (any weight)
• 2 Plastic straws (milkshake size, non-bendable)
• Styrofoam cup.
• Masking tape.
• Scissors.

What is the aim of the balloon rocket experiment?

This simple and fun science experiment teaches children about Action and Reaction. Using everyday household items, children learn how the force of air moving in one direction can propel balloon in the opposite direction, much like a rocket!

What direction do balloons move?

opposite direction
The balloon always moves in the opposite direction from the jet of air. 2. The more compressed air there is in the balloon, the more force it will have and the faster it will move. If you decrease the number of pumps (lower the air pressure), the balloon has less force and will go slower.

Who laid the foundations that apply to modern rocketry?

scientist Sir Isaac Newton
Rocketry as a Science During the latter part of the 17th century, the scientific foundations that apply to all modern rocketry were laid by the English scientist Sir Isaac Newton (1642-1727). Newton expressed his understanding of physical motion via three scientific laws.

What makes the balloon expand?

Air molecules collide into the balloon with the same energy inside and outside the balloon. These molecules now collide into the balloon with more energy resulting in increased pressure. The increased pressure causes the balloon to expand.

Can you make a balloon fly straight?

Use as much tape as it will need to make the cone one solid piece of tape and paper. Leave a hole in the bottom of the tube. Roll the lip of the balloon’s spout off the top of the now solid cone and blow the balloon up. When it is full, pinch the balloon higher up, leaving most of the spout exposed.

What happens to Stage 2 of the rocket?

Stage II is restartable, and fires twice. The first burn occurs during the final portion of the boost phase and is used to insert the second and third stage spacecraft stack into a low Earth orbit. The second stage is programmed to shut itself off once the rocket and spacecraft are in orbit around Earth.

What is a balloon rocket experiment?

The Science Behind It This experiment is all about the air and thrust! Once you let out the air inside of your balloon, it creates a forward motion called THRUST! Thrust is a pushing force created by energy that pushes your balloon all the way across your string!

What happen to the balloon when untied and released?

Explanation: According to Newton’s third law of motion “for every action, there is an equal and opposite reaction”. As a blown up but untied balloon is released, the air trapped inside the balloon pushes out of the open end. This causes the balloon to move forward.

How does a 2 stage balloon rocket work?

So, that balloon deflates first—acting like the first stage of the rocket and pushing both balloons along the string. After it has deflated, the second balloon’s nozzle is released, and it acts like the second stage of the rocket—continuing to move along the string while leaving the first balloon behind (as long as you didn’t tape them together).

How are two stages of a rocket related?

You should observe that your two balloons behave like the two stages of a rocket. One balloon keeps the other balloon’s nozzle pinched shut at first, preventing them both from deflating at the same time. So, that balloon deflates first—acting like the first stage of the rocket and pushing both balloons along the string.

Is it possible to build a balloon rocket?

Build a Balloon Rocket is a great experiment that offers many opportunities to extend the explorations. Let us see what we can do to extend the science explorations in this experiment. 1) Take two more inflated balloons and try to run over the string using the same instructions. 2) Try to inflate two balloons to different sizes or circumferences.

How does a multi stage rocket save money?

In a multi-stage rocket launch, the initial stages break away and fall back to Earth (usually burning up in the atmosphere) after their fuel is depleted. This approach saves fuel (and therefore money) because the later stages do not have to continue carrying the dead weight of the empty stages up into space.
