Exploring Chemical Reactions and Cooking Equations in Science Class

In this interactive lesson plan, students will explore the principles of chemical reactions through fun, relatable food examples such as pizza and peanut butter & jelly sandwiches. They will learn to identify reactants and products while writing equations for their favorite foods. Activities include circling ingredients and underlining results, enhancing their understanding of science concepts. The lesson encourages teamwork, responsibility, and engagement as students collaborate in experiments. Ideal for middle school classes focusing on chemistry and practical applications in cooking.

  10. Unit 5: Chemical Reactions

  11. Objectives • Agenda • Catalyst 5 • Vision Refresh 5 • R  P candle 10 • Atom Model 10 • Balanced Equation 10 • Take it Farther 5 • 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

  12. Reactants & Products In chemical reactions, substances calledreactants, interact to create different substances called products. What are the reactantsin this chemical reaction? wax + oxygen  carbon dioxide + water products

  13. Reactants & Products Will the candle still burn if one of the reactantsis no longer available? In a chemical reaction, atoms in the reactantscombine in new and different ways to form the molecules of the products. wax + oxygen  carbon dioxide + water STOP & jot!

  14. Chemical Reactions STOP & jot!

  15. 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

  16. Chemical Reactions STOP & jot!

  18. 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.

  19. 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.

  20. 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
