Today we are exploring the wonderful world of chemistry with an acid-base experiment.

Quarks, like electrons, are fundamental particles, which means they can’t be broken down into smaller parts. Or can they?

How does water turn into ice? Why is ice sometimes slippery and other times sticky? Why is it so cold? Why does it float? How are icicles made? Why are icebergs mostly underwater? What was the ice age?

NPR correspondent Geoff Brumfiel tells us, so far antimatter has mostly escaped the detection of physicists.

Today on Short Wave, Schleier-Smith takes us into her laboratory — of lasers and mirrors — to break down what’s at work.

In the basic version, students learn about the atom, its structure, the particles. They will also learn how to calculate the atomic mass and find the number of protons, neutrons, and electrons. In the advanced version, students learn about isotopes and ions.

Students are introduced to the idea and structure of an atom with an engaging craft project.

Using M&Ms candies, this exercise will demonstrate the process of radioactive decay and its uses for determining the age of a substance.

Explore the elemental composition of the world.

Atoms & molecules can be represented in many ways

Atoms are made of neutrons, protons, and electrons

Students make a one-drop puddle on their hand and observe the water evaporate to investigate the question: Why do puddles dry up?
