These straw rockets are very simple to make and nice enjoyable. You may make them plain or theme in numerous methods. We’ve made Pterodactyls and rockets!
They’re additionally a incredible introduction to forces, gravity and trajectory!
Don’t neglect I even have a e book stuffed with rocket and area science experiments for teenagers. This IS Rocket Science is on the market from Amazon within the UK and bookstores in America.
Straightforward Straw Rocket STEM Problem
There are two methods to make these: you’ll be able to both use a large straw because the rocket half ( sealed with tape at one finish ) or use paper sealed at three ends so the open finish matches over the straw.

Find out how to make a straw rocket
Paper model
Minimize a small strip of paper, fold in half and seal the highest and lengthy facet reverse the fold with tape.
This could match loosely excessive of the straw.
Place it over the straw and blow, it ought to shoot into the air!
Beautify in order for you!
Straw Model
Minimize the broader straw, so you’ve a section about one-third the size of the normal-width straw.
Utterly seal one finish of the vast straw with sellotape so no air can go by means of it. Test this by blowing down the straw. Does any air escape?
Draw an image of a rocket or different area object on a bit of paper and use sellotape (double-sided works finest ) to connect to the broader straw.
Place the broader straw onto one finish of the conventional straw and blow!
Watch your rocket fly!
Attempt pointing the straw at totally different angles and blowing tougher/much less onerous to see how the flight of the rocket modifications.
Straw Rocket Directions and Template
If you happen to’d slightly make flying butterflies than rockets, the tamplate above works properly.
Why does this occur?
While you blow air down the straw, it travels to the tip and pushes its approach out, taking the rocket straw section with it because it strikes. The tougher you blow into the straw, the extra power the air has and the additional the rocket will fly!
Change the trajectory
Discover out what occurs to the straw rocket if you happen to level it straight up. How far does it fly? Does it fly otherwise if you happen to level it horizontally?
What’s occurring?
Two forces are performing on the straw rocket. Gravity is pulling it down whereas the power from the air blown down the straw is pushing it ahead. These two forces mixed give a curved motion. An actual rocket wants to beat the gravitational power downwards.
Straw Rocket Problem – Extension Concepts
Add some weight to the straw rocket and see if that impacts how far it travels. You could possibly use cardboard as an alternative of paper for the rocket or add paper clips!
Make a number of totally different themes to your straw rockets. Crimson Ted Artwork has some stunning summer season themed straw shooters that work in the identical approach.
Extra Rocket Science for Children
If you happen to’ve obtained youngsters who love area and rockets, you would possibly like our simple bottle rocket experiment , movie canister rocket or squeezy bottle rockets!
For youthful kids, I’d suggest a rocket mouse! These are nice enjoyable for little ones, and greater siblings would possibly get pleasure from getting concerned, too!
