Blast off with a straw rocket STEM Problem. This thrilling, hands-on science exercise permits youngsters to design, assemble and launch their very own straw rockets.
Straw rockets are simple to make and use solely cheap supplies. You may make them plain or theme in several methods. We have made Pterodactyls and rockets!
They’re additionally a improbable introduction to forces, gravity and trajectory!
Do not forget I even have a e book crammed with rocket and area science experiments for youths. This IS Rocket Science is obtainable from Amazon within the UK and bookstores in America.
Simple Straw Rocket STEM Problem
There are two methods to make these: you possibly can 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.

make a straw rocket
Paper model
Reduce 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!
Adorn if you need!
Straw Model
Reduce the broader straw so you’ve gotten a section about one-third the size of the normal-width straw.
Utterly seal one finish of the large straw with sellotape so no air can go by it. Examine this by blowing down the straw. Does any air escape?
Draw an image of a rocket or different area object on a chunk of paper and use sellotape (double-sided works greatest ) to connect to the broader straw.
Place the large straw onto one finish of the conventional straw and blow!
Watch your rocket fly!
Strive pointing the straw at completely different angles and blowing tougher/much less onerous to see how the flight of the rocket adjustments.
Straw Rocket Directions and Template
Use my useful template to make the problem even simpler!
If you happen to’d quite make flying butterflies than rockets, the template above works nicely.
Why does this occur?
Once you blow air down the straw, it travels to the tip and pushes its means out, taking the rocket straw section with it because it strikes. The tougher you blow into the straw, the extra vitality the air has and the additional the rocket will fly!
Change the trajectory
Discover out what occurs to the straw rocket should you level it straight up. How far does it fly? Does it fly in another way should you level it horizontally?
What is going on on?
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 may use cardboard as a substitute of paper for the rocket or add paper clips!
Make a number of completely different themes in your straw rockets. Purple Ted Artwork has some lovely summer season themed straw shooters that work in the identical means.
Extra Rocket Science for Children
If you happen to’ve received youngsters who love area and rockets, you may like our simple bottle rocket experiment , movie canister rocket or squeezy bottle rockets!
For youthful youngsters, I would suggest a rocket mouse! These are nice enjoyable for little ones, and larger siblings may get pleasure from getting concerned, too!
