This word starts with T and ends with R, and means someone who teaches. *hint: it's not a teacher*

What is "Tutor?"

200

What is a molecule?

What is "Two or more atoms bonded together"

200

What are signs of a chemical reaction?

What is "Color change, gas bubbles, heat/cooling, light, or a new substance"

200

Why must a chemical equation be balanced?

What is "To show that mass is conserved (same atoms on both sides)"

200

What did different colored balls represent in our molecule models?

What is "Different types of atoms or elements"

400

What are the substances made in a chemical reaction called?

What is "Products"

400

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"

400

How did we show that no atoms are lost during a reaction?

What is "By counting atoms on both sides of the equation"

400

Many students experience this when the teacher calls on them, and they weren’t paying attention.

What is "being caught off guard or awkwardness?"

500

What does a chemical formula (like H₂O) tell us?

What is "The types and number of atoms in a molecule"

500

What happens to atoms during a chemical reaction?

What is "They are rearranged to form new substances"

500

What tool can help show conservation of mass clearly?

What is "A model or balanced chemical equation"

500

What did our activities help us understand about matter?

What is "That it changes in reactions, but no atoms are lost or gained"

500

This process causes water to move through a plant from roots to leaves.

What is "transpiration?"
