  1. Seats: period3

  2. Seats: period10

  3. Catalyst 4 minutes! • Which side of a chemical equation are reactants on? Right or Left? • Which side of a chemical equation are products on? Right or Left? • Copy this chemical equation then circle the 2reactants & underline the 2products 2C4H10 + 13O2 → 8CO2 + 10H2O • Will a chemical reaction (like burning a candle) continue if one of the reactants is no longer available? • En calladode unareaccionquimicaestan los reactantes? Derechaor Izquierda? • En callado de unareaccionquimicaestan los productos? Derechaor Izquierda? • Copiaestareaccionquimicay circula los 2reactantes & subrayalos 2productos 2C4H10 + 13O2 → 8CO2 + 10H2O • Va a seguirunareaccionquimica(comoquemaruna vela) sialguno de los reactantesya no esdisponible?

  4. 100.Benjamins • 1: Raise a hand • 1: Exemplary answer in sentence • 1: Exemplary answer with thought • 1: Demonstrate “North Star” traits • 3: 100% seated before the bell • 3: “Ready for your attention” • 3: Lab /activity clean up • 5: 100% on task during practice • 5: 80% exit ticket average Free Sit on Friday!

  5. 100.Benjamins love it or hate it! hot seat ! hot seat ! music ! hot seat !

  6. Unit 5: Chemical Reactions

  7. Objectives • Agenda • Atom Model 15 • Balanced Equation 20 • Take it Farther 10 • Exit Ticket 5 • We are learning to… • explain that no atoms are created or destroyed in a chemical reaction • We will be successful when we can… • identify reactants & products observed in chemical reactions elephant toothpaste

  8. Atom Model 10 minutes! • Color carbonatoms black, oxygenatoms red, & leave hydrogen atoms white • Cutout atoms • Use ½ the atoms to make reactantson the left side on the right side of the box • Write the chemical formula under each of the reactants • Draw a + sign between the reactants • Draw an after the reactants • When both you & your partner are ready, raise your hand! • Rearrange the atoms to make products on the right side on the right side of the box • Write the chemical formula under each of the products • Draw a + sign between the products • When both you & your partner are ready, raise your hand! • Use 100% the atoms to make the complete chemical equation • Glue the atoms to the paper 1

  9. Balanced Equations STOP & jot!

  10. Take it Farther 5 minutes! 0

  11. Conceptos Claves Cuando se forma una nueva sustancia, el cambio se llama una reacción química. • En una reacción química, los átomos y las moléculas que interactúan entre sí se llaman reactivos. • En una reacción química, los átomos y las moléculas producidas por la reacción se llaman productos. • En una reacción química, sólo los átomos presentes en los reactivos pueden terminar en los productos. No se crean nuevos átomos, y los átomos no se destruyen.

  12. Key Concepts When a new substance is formed, the change is called a chemical reaction. • In a chemical reaction, the atoms and molecules that interact with each other are called reactants. • In a chemical reaction, the atoms and molecules produced by the reaction are called products. • In a chemical reaction, only the atoms present in the reactants can end up in the products. No new atoms are created, and no atoms are destroyed.

  13. Exit Ticket 4 minutes! 4 minutes! • You may use your assignments! • You must work quietly& independently. • Talking will NOT be tolerated. BIG goal = 80% 0
