Morse code STEM activity

Morse code STEM activity 

Kids can build a basic telegraph circuit and engage in offline code-breaking challenges. 

These hands-on activities blend electrical engineering, logic, and a fun way to send secret messages.

Hands-On Circuit Building

Build a functioning telegraph system using basic electronics Components 

A 3V battery pack, 

an LED,

 a power buzzer,

 a push switch.

Wire the components in a simple series circuit. When the switch is held down, it completes the circuit, allowing current to flow so the LED flashes and the buzzer sounds.

The Coding: 

Use short presses for "dots" and longer presses (about 3 seconds) for "dashes" to spell out messages.

Send secret messages for other group to decode.

Methanol a promising alternative to fossil fuels.  In the area of- Transportation Methanol can be used in road, rail, and marine transportation. It can be more affordable and reliable than electric vehicles (EVs) in some situations, like long-haul transportation.  Methanol engines can be as efficient as diesel engines without the diesel emissions. Energy Methanol can be used in boilers, process heating modules, tractors, and commercial vehicles.  Cooking Methanol can be used as a cooking fuel in stoves and canisters that don't require pipes or regulators.    Benefits Environmental impact Methanol can reduce nitrogen oxide emissions by up to 80% and carbon dioxide emissions by up to 95% compared to fossil fuels.  Accidental spills not harmful for environment as methonol is biodegradable,  ' Production Methanol can be produced from a variety of sources,  agricultural products,  municipal waste,  wood, and biomass.  from chemical recyc...

3I-Atlas Closest to Earth on 19 December 2025 danger of hitting Earth

Image
3I-Atlas story so far On July 1, the NASA-funded ATLAS ( Asteroid Terrestrial-impact Last Alert System ) survey telescope in Rio Hurtado, Chile, first reported observations of a comet that originated from interstellar space. Arriving from the direction of the constellation Sagittarius, the interstellar comet has been officially named 3I/ATLAS. It is currently located about 420 million miles (670 million kilometers) away. This diagram shows the trajectory of interstellar comet 3I/ATLAS as it passes through the solar system. It will make its closest approach to the Sun in October.  It is currently about 4.5 au (about 416 million miles or 670 million km) from the Sun. 3I/ATLAS will reach its closest approach to the Sun around Oct. 30, at a distance of 1.4 au (about 130 million miles or 210 million km) — just inside the orbit of Mars. 3I-Atlas Closest to Earth on 19 December 2025 danger of hitting Earth Although the trajectory of 3I/ATLAS brought it just inside the orbit of Mars, it is...

Déjà vu & Jamais Vu

Image
Déjà vu & Jamais Vu Déjà vu is a French phrase that translates literally to "already seen". It is a loanword adopted into English to describe the, often fleeting, psychological sensation of having already experienced a current situation. It consists of déjà ("already") and vu ("seen", past participle of voir).  Origin : Coined/popularized in France, with a potential origin in 1876 by philosopher Émile Boirac. Why it happens? In other words, it happens when there’s a miscommunication between two parts of your brain: The one responsible for memories (your temporal lobe) and the one responsible for taking in new information ( your hippocampus). Jamais Vu Jamais vu is a French phrase. It translates literally to "never seen". In psychology, it describes the phenomenon where a familiar situation, word, or person feels suddenly new, strange, or unfamiliar. It is commonly considered the opposite of déjà vu (already seen).  .
