Journal Entry:

Paper and a log are made from the same compounds. Why don’t they burn at the same speed?

Learning Intentions

• We will learn the conditions that affect rate of reaction.
• We will learn what a catalyst is and how they work in chemical reactions.

Closing Task:

 You can explain factors that will increase the rate of a reaction.

Content Standards being covered:

Student understands what the letters and numbers stand for in a compound formula, can use those letter and numbers to determine how many of each type of element there are in a formula.

Student can create mathematical representations of chemical reactions and use them to make calculations about products and reactants.

Students can use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction. (HS-PS1-7 and CCC Energy and Matter)
