STEM Challenge: 20 | Rubber Band Powered Boat | Plastic Bottle, Sticks, Rubber Band, No Tape or Glue

Описание: [EN] Making a boat for your science project is really easy. All you need is an empty bottle, some bamboo sticks or wooden dowels or skewers, a piece of craft stick or tongue depressor for paddle, and some rubber bands. No glue to tape required!

[UR] Science project ke liye boat banana bohat easy hai. Aap ko sirf ek khaali bottle, kuch bamboo sticks ya wooden dowels ya skewers, paddle ke liye ek craft stick ya tongue depressor, aur kuch rubber bands chahiye hotay hain. Is project mein na glue ki zaroorat hai aur na hi tape ki.

Key Concepts:

Energy Storage & Release – Rubber band ko twist kar ke energy store hoti hai aur chhorte hi motion create hota hai.

Force & Motion – Paddle pani ko peeche push karta hai aur reaction mein boat aagay move karti hai.

Newton’s Third Law of Motion – Action aur reaction ka principle real-life model mein observe hota hai.

Thrust – Paddle ki movement pani ke against thrust paida karti hai.

Simple Machines in Action – Paddle ek simple mechanical system ki tarah kaam karta hai.

Engineering Design – Simple materials use kar ke functional floating model banana.

Buoyancy (Floatation) – Bottle pani par is liye float karti hai kyun ke woh pani ko displace karti hai.
