Atoms & Molecules
What is the smallest part of an element?
What is "An atom"
What is a chemical reaction?
What is "A process where substances change into new ones"
What does the Law of Conservation of Mass say?
What is "Matter is not created or destroyed in a chemical reaction"
In Experience 1, what did we model using atoms?
What is "Molecules or compounds"
This word starts with T and ends with R, and means someone who teaches. *hint: it's not a teacher*
What is "Tutor?"
What is a molecule?
What is "Two or more atoms bonded together"
What are signs of a chemical reaction?
What is "Color change, gas bubbles, heat/cooling, light, or a new substance"
Why must a chemical equation be balanced?
What is "To show that mass is conserved (same atoms on both sides)"
What did different colored balls represent in our molecule models?
What is "Different types of atoms or elements"
When you work together with classmates on a project, it’s called this.
What is "a group project or teamwork?"

In the equation H₂ + O₂ → H₂O, what’s missing to balance it?
What is "A coefficient: 2H₂ + O₂ → 2H₂O"
In Experience 4, what did we do with chemical equations?
What is "We learned to balance them to conserve mass"
Spell the school name *bonus if you sing it*
What is "S-C-H-I-M-E-L-P-F-E-N-I-G"
How are elements and compounds different?
What is "Elements have one kind of atom; compounds have two or more"
What are the substances made in a chemical reaction called?
What is "Products"
How do we know if mass is conserved in a reaction?
What is "The number and type of atoms are the same before and after"
How did we show that no atoms are lost during a reaction?
What is "By counting atoms on both sides of the equation"
Many students experience this when the teacher calls on them, and they weren’t paying attention.
What is "being caught off guard or awkwardness?"
What does a chemical formula (like H₂O) tell us?
What is "The types and number of atoms in a molecule"
What happens to atoms during a chemical reaction?
What is "They are rearranged to form new substances"
What tool can help show conservation of mass clearly?
What is "A model or balanced chemical equation"
What did our activities help us understand about matter?
What is "That it changes in reactions, but no atoms are lost or gained"
This process causes water to move through a plant from roots to leaves.
What is "transpiration?"
