What this lesson covers
Why it matters
A handful of curious minds turned fire, air and metal from mysteries into laws. Each one cracked a different secret of matter.
Predict first
Who is called the 'Father of Modern Chemistry' for proving mass is conserved?
Lavoisier proved matter is neither created nor destroyed — he reacted things in a sealed jar and the total mass never changed.
- Antoine Lavoisier — correct
- John Dalton
- Marie Curie
What you do
Match each discovery to the chemist who made it.
Check yourself
Why did Lavoisier seal his jar before reacting things inside?
If gas escapes, the mass looks smaller. Sealed, the mass stays exactly the same — matter is conserved.
Who proposed that all matter is made of atoms?
John Dalton's atomic theory said every element is made of its own tiny atoms.
- So escaping gas couldn't fool the mass reading — correct
- To keep the reaction warm
- To make it react faster
- Dalton — correct
- Curie
- Lavoisier
