Reaction Rate:How fast or slow a chemical reaction takes place. Like how long it takes for your popcorn to pop in microwave!
Catalyst:A substance that increases the rate of a chemical reaction without being consumed by the reaction itself. Like a cheerleader at a game who helps boost team spirit but doesn't play in game!
Reactant: A substance that undergoes change during a reaction. Think about baking cookies - flour, sugar, and butter are your reactants!
