Unit 3 - CHEMICAL Reactions
Unit 3 Class Activity Information, Labs, and Demo Videos
These should be used when you need a link during class for an activity or there are also files specific for when you are absent on the day of a demo or a lab to use to catch up. If you were present in class but you want/need to see the lab or demo again you can also use the absent student links.
Lesson 1:
Station #1: Burning Tissue (for absent students)
Station #2: Zinc with Copper (II) Sulfate (for absent students)
Lesson 2:
Lesson 2 Slide Deck (used by everyone for the properties, pictures, and videos of the fuels you need to complete the lesson)
Formula Writing: Roman Numerals and Polyatomic Ions (Google Slide Deck used by everyone during class)
Ion Reference Sheet (handout - listed here for reference as well)
Forensic Fiber Lab - Flame Tests (for absent students)
This video goes through how to use the table in Lesson 2 to help you identify the fabrics by their flame tests.
Lesson 3:
How to Balance Chemical Equations (Google Slide Deck used by everyone during class)
This goes over the slide deck we covered in class on how to balance chemical equations (for absent students).
This can also be used by anyone who needs to go through the information again to understand more or to review.
Investigating Combustion of a Candle (Testing for Carbon Dioxide) (for absent students)
Lesson 4A:
How to Balance Equations (Google Slide Deck used by everyone during class)
Lesson 4B:
Types of Chemical Reactions Examples (Google Slide Deck used by everyone during class)
Composition Reaction - Iron and Sulfur Reaction Video
Decomposition Reaction - in class Electrolysis Demo (here is a VIDEO for absent students)
Single Replacement Reaction - in class Copper and Silver Nitrate Demo (here is a VIDEO for absent students)
Double Replacement Reaction - Lead (II) Nitrate with Potassium Iodide Video
Combustion Reaction - in class 'Pop'/Bark Test for Hydrogen Demo (absent students this was already in the Electrolysis Demo video above)
Lesson 4D:
Reactions Lab - Day 1 (Reactions #1-4) (for absent students)
Reactions Lab - Day 2 (Reactions #5-7) (for absent students)
Lesson 5:
Lesson 5A Resources:
This goes over the formula mass problems (#1 and #2, slide one of the video), the balanced equation (#3, slide two of the video), and the stoichiometry example (#10, slide three and four of the video) we cover in class, they are generally covered two different days so if you were absent for either part you can use this.
This can also be used by anyone who needs to go through the information again to understand more or to review.
Lesson 5B Resources:
This is mostly for absent students, it goes over the concept of mole to mole conversion ratios that is part of stoichiometry by going through the beginning of Lesson 5B including Problem #1 both part A and B like we do on the board in class.
This can also be used by anyone who needs to go through the information again to understand more or to review.
Lesson 5C Resources:
Absent students this goes over the stoichiometry example problem we worked through in class. There is also a document HERE that has all the steps written out, but this is a video of me talking through the steps as well.
This can also be used by anyone who needs to go through the information again to understand more or to review.
Lesson 6 and Lesson 7:
Simulation Link: Bond Formation (used by students in class and absent students)
Lesson 8:
Simulation One: Molecule Separation (used by students in class and absent students)
Simulation Two: Bond Formation (used by students in class and absent students)
Lesson 9:
Argon Gas Video (used by everyone)
Noble Gas PhET Simulation (used by everyone)
Molecular Model Kit Video (absent students ONLY - for #5A, 6E and 6F as well as the table in #7)
How to Draw Lewis Structures Review Video (used by everyone)
Lesson 10:
No additional resources needed
Lesson 11:
Demo #1 - Barium hydroxide and Ammonium chloride (used by everyone)
Demo #2 - Dissolving and Energy (for absent students)

Glow Stick Demo Slides (for absent students)
Lesson 13:
Coming soon
No additional resources needed
(for absent students)
Unit 3 Resource Materials
These are videos and other resources we used in the lessons (those are in the calendar on the day we used them as well) and any other resources that may be helpful if you need extra help.
Practice Balancing Equations - An interactive website where you can choose the coefficients to balance the equation and then check your answer immediately to see if it is right. Has three levels of difficulty to choose from. If you get it wrong it highlights the coefficients that are incorrect.
A very basic first introduction vodcast to balancing equations and how to set up an atom inventory. Only about 5 minutes long with three simple examples at the end if you need help with how to set up and use an atom inventory.
Types of Chemical Reactions Infographic
HERE is a link to a "Types of Chemical Reactions" infographic (ignore the neutralization reaction listed, we do not cover those at this level).
This goes over two formula mass examples that are random and not from any particular worksheet. ANYONE can use this if you need to see more examples before you complete the formula mass worksheet in the Extra Practice Packet and toward the quiz.
Molar Mass (Formula Mass) Concept Builder - For this concept builder "Calculating Molar Mass" is the best practice for your quiz. The "Atom Counting" level is fine as well if you need practice just counting how many of each element. The "Out of this World" level is also good practice if you need more of a challenge as it has "Alien" elements and a new Periodic Table to use so it will be things you are less familiar with. Remember they have a "help" section that will review information relating to the concept builder for you as well.
Stoichiometry Concept Builder - The "Apprentice Level" is mole-to-mole practice like Lesson 5B was and is good practice at using the coefficients to build relationships between substances. The Master and Wizard level don't align very well with the level of Stoichiometry we are doing and I would not recommend them unless you talk to me first about the format. They do not go gram to gram, they all stop at moles. Remember they have a "help" section that will review information relating to the concept builder for you as well.
MORE Molar Mass (Formula Mass) Practice - We have used this site for balancing equations practice already - you can generate your own quiz through this site. Choose the number of practice problems you want, pick "Molar Mass (aka formula weight)" as the option for problem type, and then select if you want fill-in-the-blank or multiple choice for the answers.
Stoichiometry Practice Problems - From the same site as the last practice set - choose how many problems you want, pick if you want to write formulas or not, pick if you want to balance the equations or not and generate a practice quiz.
Lewis Dot Structures Concept Builder Practice - the middle level ("Master Configurator") is the best level for practice on this concept builder. Draw all three Lewis Structures they show yourself (based on the number of atoms for each element they show) and then compare that to their answer to see if theirs is right and pick the ones that are incorrect.
(after Lesson 12) Collision Theory Concept Builder - the middle level ("The Collision Model") is the one to use to practice our basic concepts of collision theory.
