Lesson Descriptions
Day 13 - Introduction to Chemical Reactions and Balancing: Students will explore how Chemical Reactions occur and be introduce to the Law of Conservation of Mass/Matter and balancing Chemical Equations. The students will discover how chemical reactions actually happen by watching a short Youtube video. The ideas from the video are conjoined with a PhET simulation so that the students can explore these ideas further on their own. Balancing Chemical Equations will be introduced with class notes and a homework worksheet. Balancing will be touched on at the beginning of Day 14. This lesson is in alignment with NGSS HS-PS1.B and HS-PS1-7.
Day 14 - Overview of Balancing, Exothermic vs Endothermic Reactions, Reaction Coordinate diagrams: This day does not have a complete lesson plan represented in this unit outline. On this day, students will be able to ask questions about balancing, so that the topic from the day before is solidified for them. The teacher should then relate the Reaction Coordinate Diagrams the students saw on Day 13, and give them meaning by introducing Exothermic and Endothermic reactions. This can be done with class notes and a demonstration of the two types of reactions. This day then leads into Day 14 by introducing two overarching categories of Chemical Reactions. Days 15 and 16 will continue to break down Chemical Reactions into more specific categories. This lesson is in alignment with NGSS HS-PS1-4.
Day 15 - The 5 types of Reactions: Lab: This lesson will further break down Chemical Reactions into 5 sub-categories: Composition, Decomposition, Single-Replacement, Double-Replacement, and Combustion. To introduce the students to these types of reactions, there will be a brief period of notes. The rest of the class, will be given to the students time to explore these 5 reactions in the lab. One of the types of reactions (decomposition) will be done as a demo (Elephant's Toothpaste). This lesson will show the students the phenomena we will be exploring, and give them a concrete example of each type of reaction. Working in the lab will also spark their curiosity of the subject.This lesson is in alignment with NGSS HS-PS1-2.
Day 16 - The 5 types of Reactions - Reinforcement: In this lesson, the students will be practicing writing out Chemical Equations for the 5 types of reactions, practice identifying the 5 types of reactions from Chemical Equations, and practice predicting products for the 5 types of chemical equations based off of the reactants given to them. These activities should help really solidify the 5 different types of reactions for the students. This lesson is in alignment with NGSS HS-PS1-2.
Day 17 - Equilibrium: For this lesson, students will be looking at the idea of Chemical Equilibrium. Students will be introduced to the idea of a forward and reverse reaction of a chemical system. The teacher can use a demonstration of one student putting together and another student pulling apart legos to give an example of what equilibrium might look like. The students will also be introduced to how Chemical Equilibrium can be changed (le Chatelier's principle) using real world examples. This lesson is in alignment with NGSS HS-PS1-6.
