What is hydrogen?
I’m the force that pulls objects toward Earth.
What is gravity?
I’m the type of change that forms a new substance.
What is a chemical change?
I’m the push or pull that makes things move.
I’m the push or pull that makes things move.
These subatomic particles orbit the nucleus and have a negative charge.
What are electrons?
I’m the noble gas used in balloons to make them float.
What is helium?
I’m the scientist who formulated the laws of motion.
Who is Isaac Newton?
I’m the gas often released when vinegar reacts with baking soda.

What is a catalyst?
I’m the number of periods in the modern periodic table.
I’m the part of the atom responsible for bonding with other atoms.
What are valence electrons?
I’m the kind of change where no new substance is made—like melting ice.
What is a physical change?
I’m the force that resists motion between two surfaces.
What is friction?
I’m the part of a solution that dissolves the solute.
