Science Topics Made Simple

Big ideas, plainly put

A handful of science ideas show up everywhere: energy moving around, patterns repeating, and evidence deciding what we accept as true. Getting comfortable with those makes new topics far less intimidating.

A good starting pair is the difference between weather and climate and how photosynthesis works — both come up constantly and are easy to picture.

Topics covered here

Simple, general explainers on subjects like:

• Photosynthesis — how plants make food from light
• Weather vs climate — short-term conditions vs long-term patterns
• Gravity — the pull that keeps things grounded and orbits going
• Energy — the ability to do work, in its many forms
• The scientific method — how ideas get tested against evidence
• Ecosystems — how living things and their environment interact
• Basic biology — the fundamentals of living systems
• Basic physics — matter, motion, and forces in everyday terms

Thinking like a scientist

The habit behind all of science — asking how we know something — is useful far beyond the lab. The Productivity section touches on critical thinking in the same spirit.
