100+ Interesting Science Facts for Students

There are many things around us that we see every day but may not know the reason behind them. Ice stays on top of water, a pressure cooker cooks food faster, and a simple mirror shows our reflection. Have you ever thought about why these things happen? Science has an explanation for all of them. Here are 100+ everyday science facts covering different topics that students will enjoy reading and learning.

100+ Everyday Science Facts Every Student Should Know

Science is not just something we learn from books; we can find it in many things we do and see every day. Let’s look at some interesting facts that explain common events, objects and natural phenomena in simple words.
