Everything around us is made up of different elements. The air has oxygen (O) and nitrogen (N). Plants and people have lots of carbon (C). Hydrogen (H) is in water. Play until you discover which particle (or particles) determines the name of the element you build. What did you discover?

Background:
Atoms of the same element always have the same number of protons, but the number of neutrons can vary. When this happens, the atoms are called isotopes.
Task:
Use the Claim–Evidence–Reasoning framework to explain what an isotope is.
Claim:
Write a clear statement that defines what an isotope is.
Evidence:
Provide at least two pieces of scientific evidence (for example, use specific isotope examples like carbon-12, carbon-13, and carbon-14, or data showing proton and neutron numbers).
Reasoning:
Explain how your evidence supports your claim. Connect your ideas to scientific principles about protons, neutrons, and atomic identity.
