Tell Me and I Forget. Teach Me and I Remember. Involve Me and I Learn.Origin and HistoryThis widely quoted proverb is often attributed to Benjamin Franklin, though its roots may go deeper, possibly influenced by Confucian philosophy or earlier oral traditions.

What Is an Earthquake?An earthquake happens when the ground suddenly shakes. This shaking is caused by movements inside the Earth.

Over time, a lot of energy builds up. When the plates finally move, the energy is released as an earthquake. The ground can shake a little or a lot — depending on how much energy is released. How Do We Measure Earthquakes?Scientists use a tool called a seismograph to measure earthqu
What Is the Solar System?The Solar System is made up of the Sun and everything that moves around it. The Sun is a giant ball of hot gas that gives us light and heat.

The basic equation of photosynthesis is:Carbon dioxide (CO₂) + Water (H₂O) + Sunlight → Glucose (C₆H₁₂O₆) + Oxygen (O₂) Let’s break it down:1️⃣ Water is absorbed from the soil through the plant’s roots.2️⃣ Carbon dioxide enters the plant through small openings in the leaves called stomata.3️⃣ Sunlight is captured by chlorophyll.
